biodiversity: The challenge of megadiverse Mediterranean climate ecosystems." Austral
Ecology 35(4): 406-422.
The Mediterranean climate regions of Western Australia and South Africa are
recognized as global hot spots of diversity. Both are threatened by climate
changes that are projected to have significant impacts on the quantity and
variability of rainfall and affect key ecosystem drivers (e.g. fire regimes). This
poses significant challenges to monitoring programs designed to detect these
impacts. Effective monitoring of the impact of climate change on biodiversity
(rather than individual species) requires a cross-disciplinary, coordinated,
focused and integrated approach. Ideally, this should involve a multidisciplinary
team of specialists working to a common plan on the same set of plots. The
contributions of ‗citizen scientists‘ are potentially useful if well managed.
Biodiversity per se (across all kingdoms of life, and including the levels of the
gene, population and community) should be monitored, especially key species
interactions and processes. Forestcheck is an example of such a program which
has been applied in forests in south-west Western Australia since 2001. In
concert with measuring the direct impact of climate change on biodiversity and
the indirect impact of factors that affect biodiversity (such as disease, invasive
species, fire regime and habitat removal), there is a need for a proactive focus on
creating, maintaining and monitoring resilience to climate change impacts in
ecosystems. It is also necessary to monitor the effectiveness of management
actions such as vegetation thinning, changes in fire regimes, species
translocations and revegetation of farmland to link isolated protected areas in
agricultural landscapes, remnant native vegetation in rangelands and extensive
protected areas. A pluralist approach is recommended. This should include
natural experiments, matched photographs where available, passive adaptive
management, active adaptive management and traditional reductionist scientific
investigation. The resultant synthesis of information from this range of sources is
likely to be a predictive, robust and credible record of historical change.
Abuodha, P. A. O. and C. D. Woodroffe (2010). "Assessing vulnerability to sea-level rise
using a coastal sensitivity index: a case study from southeast Australia." Journal of
Coastal Conservation 14(3): 189.
Many of the world's coasts appear vulnerable to the impacts of climate change
and sea-level rise. This paper assesses the application of a coastal sensitivity
index (CSI) to the Illawarra coast, a relatively well-studied shoreline in southeast
Australia. Nine variables, namely (a) rock type, (b) coastal slope (c)
geomorphology (d) barrier type (e) shoreline exposure (f) shoreline change (g)
relative sea-level rise (h) mean wave height and (j) mean tide range, were
adopted in calculation of the CSI (the square root of the product of the ranked
variables divided by the number of variables). Two new variables, shoreline
exposure and barrier type, were trialled in this analysis and the extent to which
these increased the discriminatory power of the index was assessed. Four
iterations of the CSI were undertaken using different combinations of ranked
variables for each of 105 cells in a grid template, and the index values derived
were displayed based on quartiles, indicating sections of coast with very high,
high, moderate and low sensitivity. Increasing the number of variables increased
the discriminatory power of the index, but the broad pattern and the rank order
were very similar for each of the iterations. Rocky and cliffed sections of coast
are least sensitive whereas sandy beaches backed by low plains or dunes record
the highest sensitivity. It is difficult to determine shoreline change on this coast,
because individual storms result in substantial erosion of beaches, but there are
prolonged subsequent periods of accretion and foredune rebuilding.
Consequently this variable is not a good indicator of shoreline sensitivity and the
index is unlikely to provide a clear basis for forecasting future recession of
beaches. The results of this study provide a framework for coastal managers and
planners to prioritize efforts to enhance the resilience or consider adaptation
measures in the coastal zone within a study region. Sensitivity of the coast if
considered in conjunction with other social factors may be an input into broader
assessments of the overall vulnerability of coasts and their
communities.[PUBLICATION ABSTRACT]

Climate warming due to the enhanced greenhouse effect is expected to have a
significant impact on the natural environment and human activity in high latitudes.
Because of its geography, wide coastal areas, water resources, forests, and
wetlands, the environment of Estonia is sensitive to climate change and sea level
rise. Climate change scenarios for Estonia were generated using a Model for the
Assessment of Greenhouse-gas Induced Climate Change (MAGICC) and a
regional climate change database, Scenario Generator (SCENGEN). Three
alternative emission scenarios were combined with data from 14 general
circulation model experiments. The assessment results of forest resources using
RipFor, a forest-soil-atmosphere model, show that climate warming would
enhance forest growth in Estonia resulting in increased productivity (2-9%) of
harvestable timber on highly productive sites. Nutrient mobility increases greatly
and in highly permeable soils with stable vegetation, increased mobility may
result in nutrient losses through leaching. The assessment results of water
resources using the simple water balance model, WatBal, show that the runoff
regime of Estonian rivers would equilibrate and the groundwater table would rise.
Climate warming would not cause any particular problems with water supply but
the groundwater quality may suffer from increased leaching. Due to milder
winters and increased storminess, the destruction of coastal areas, inundation of
wetlands and disappearance of rare plant communities in coastal areas would be
the most damaging results of climate change. Most sandy beaches high in
recreational value would disappear. However, isostatic uplift and settlements
inland from the present coastline reduce the risk of socio-economic decline.

The main emphasis of their paper is on allowing greater freedom in quantifying
some of the model input parameters that influence coastal response to sea-level
rise (sediment supply, underlying geology, profile shape). 2006) provide two case
studies of model application that demonstrate the effect of considering
uncertainty in model input parameters (profile shape, geological outcrop, seawall
presence, longshore sediment supply. Similarly, COOPER and NAVAS (2004)
demonstrated in Dundrum Bay, Northern Ireland, that natural bathymetric change
produced by sediment accumulation on the inner shelf modified the pattern of
wave-sediment interactions across the surf zone. Isolating the effects of sea-level
change from storms and other influences at decadal timescales has proved
impossible, and no study has yet been able to demonstrate a conclusive link
between sea-level change and coastal response at decadal timescales on an
open ocean coast. Simple geometric models of shoreline response to sea-level
change rely on a variety of assumptions regarding the relationship between wave
energy, sediment grain size, and profile shape.

This book is a solid summary of the current situation, by the Australian
Government's Expert Advisory Group on Biodiversity and Climate Change. It
includes lots of good information, is logically assembled and well presented. The
book is published by the Commonwealth Scientific and Industrial Research
Organisation (CSIRO) and the Australian Government and has a ‗CSIRO report‘
style, covering the bases broadly rather than homing in or hammering home a
single point. It assembles research from a range of sources, but it is not in itself a
research publication. It will be a useful reference for natural resource
management coordinators, but it is too detailed to be read by practising
politicians. It will be useful in teaching, though the introductory chapters should
already be familiar to most biology students.
There are eight chapters with text boxes by additional contributors. Some of these are
referenced, some not. There are no lists of text boxes or contributing authors,
figures or tables. There is no summary, and the introduction reads as terms of
reference. Chapters two and three provide an overview of Australian biodiversity,
its origins and values. Figure 3.7 (p. 30) seems to have a printing error, with
countries in sub-Saharan Africa shown using the same symbols and colours as
those in central Asia.
Chapter four provides a condensed overview of climate change projections, using
relatively complex graphical presentations. References are a little confusing. For
example, figures 4.5 and 4.6 (p. 60) are based on a 2007 article in Science, with
2008 data provided by two of the authors of that article but referenced to the
American Association for the Advancement of Science. Similarly, the caption to
figure 7.1 on p. 145 refers to the Intergovernmental Panel on Climate Change
(IPCC) Third Assessment Report but actually references the Fourth.
For a number of climate change parameters, measured values in recent years exceed
even the ‗worst-case‘ IPCC scenarios, so-called business as usual. This is
entirely unsurprising, since business, in fact, continues to grow; and the $5 trillion
‗economic crisis‘ of the last couple of years was a barely detectable blip in its
growth. The simplified comparison in figure 7.2 (p. 145), showing the IPCC's
‗runaway‘, ‗stabilization‘ and ‗recovery‘ scenarios mentions that ‗runaway‘ is in
fact only ‗business as usual‘. It does not mention, however, that it is at least as
likely, if not even more so, that economic growth and carbon emissions will
continue to accelerate, so that climate change may well exceed even the
‗runaway‘ scenario.
Chapter five is perhaps the core of the book, reviewing research on actual and
projected responses of Australian species and ecosystems to climate change.
There are generalized discussions of lags, thresholds, feedback and nonlinearity;
and examples drawn from a range of terrestrial and marine ecosystems.
Chapter six argues that current approaches to conservation policy, themselves relatively
weak, will be even less effective under climate change. It suggests four
now-standard adaptive responses: enhanced resilience, landscape connectivity,
enlarged reserves and ex-situ conservation. Off-reserve conservation and
ecosystem restoration are mentioned, but barely. The authors note the ‗historical
dominance of production industries over conservation‘ (p. 140) but they argue for
combining the two on the same landscape. Perhaps what they have in mind is
the conversion of production forests and private farmland to conservation. But
the forestry, fisheries and mining industries will interpret this phrase to mean that
they should have access to protected areas.
Chapter seven provides a synthesis, largely through some multi-page fine-print tables.
Table 7.1 (pp. 154–158) contrasts biodiversity management under ‗stationary‘
and ‗changing‘ climates. Most strategies listed, however, would apply equally to
both. Table 7.2 suggests funding mechanisms for conservation in different
landscapes: amenity migrants, conservation stewardship payments, carbon
offsets, industry levies and land buy-backs. These have been debated for
decades: each is possible, but none is easy. Other suggestions are: an annual
national forum; a national biodiversity trust; and a new profession of biodiversity
conservation facilitators. Nature conservation trusts already exist. The profession
of private conservation broker also exists in the USA, supported by tax
arrangements for conservation easements that do not yet apply in Australia.
A short concluding chapter argues only for: new approaches, public debate, more
funding, better governance and emission mitigation as well as adaptation. These
are broad and generalized, so the federal government can endorse them without
political risk. The strength of this volume therefore is not in its rather weak policy
recommendations, but in the large central synthesis chapter on impacts, and the
subsequent discussions on potential management approaches
Bulleri, F. and M. G. Chapman (2004). "The introduction of coastal infrastructure as a
driver of change in marine environments." Journal of Applied Ecology 47(1): 26-35.
1. Coastal landscapes are being transformed as a consequence of the increasing
demand for urban infrastructure to sustain commercial, residential and tourist
activities. A variety of man-made structures, such as breakwaters, jetties and
seawalls have thus become ubiquitous features of intertidal and shallow subtidal
habitats. This transformation will accelerate in response to the exponential
growth of human populations and to global changes, such as sea-level rise and
increased frequency of extreme meteorological events (e.g. storms). Here, we
provide a critical overview of the major ecological effects of increasing
infrastructure to marine habitats, we identify future research directions for
advancing our understanding of marine urban ecosystems and we highlight how
alternative management options might mitigate their impacts. 2. Urban
infrastructure supports different epibiota and associated assemblages and does
not function as surrogate of natural rocky habitats. Its introduction in the intertidal
zone or in near-shore waters can cause fragmentation and loss of natural
habitats. Furthermore, the provision of novel habitat (hard substrata) along
sedimentary shores can alter local and regional biodiversity by modifying natural
patterns of dispersal of species, or by facilitating the establishment and spread of
exotic species. 3. Attempts to use ecological criteria to solve problems of urban
infrastructure are promising. Incorporating natural elements of habitat (e.g.
wetland vegetation; seagrass) into shoreline stabilization can reduce ecological
impacts, without impinging on its efficacy in halting erosion. Likewise, improving
the ecological value of artificial structures by adding features of habitat that are
generally missing from such structures (e.g. rock-pools) can contribute to
mitigation of the detrimental effects of urbanization on biodiversity. Management
of anthropogenic disturbances (e.g. maintenance works; harvesting) to artificial
habitat is, however, necessary if such attempts are to be successful. 4. Synthesis
and applications. Increasing our understanding of the ecological functioning of
marine habitats created by urban infrastructure and incorporating ecological
criteria into coastal engineering are crucial for preserving biodiversity in the face
of the growth of human populations in coastal areas and of forecasted global
changes. Achieving this goal will need strong collaboration between engineers,
managers and ecologists.

events?" Geo-Marine Letters 28(1): 23-30.
The Gold Coast sandy beaches of Queensland (Australia) are exposed to
energetic wave conditions. Storms, particularly tropical cyclones, have a high
potential of destruction. The Gold Coast has not experienced excessive erosive
events over the past 30Â years. However, some climate indicators suggest that
cyclone frequency is likely to increase in response to global climate change
within the near future. Over a 2-month period in early 2006, beach surveys were
undertaken with a theodolite total station at four different sites. Offshore wave
conditions were provided by SWAN regional wave modelling. During this study,
the Gold Coast was exposed to three major storms, the first one being the
second most energetic over the past 30Â years. Results show a substantial
variability of the beach response to these events along the Gold Coast, and that
engineering structures do not have marked effects. Easterly swells have the
greatest impact on the Gold Coast sub-aerial beach morphology. When low
wave-energy conditions prevail, the southern Gold Coast beaches recover more
quickly than the northern ones, as they are sheltered from high SE waves and
draw advantage from the artificial sand bypassing system. Nevertheless, the data
show that the Gold Coast beaches are exceedingly fragile. For instance, the
early March decadal event considerably weakened the beaches, which resulted
in surprisingly high erosion rates all along the Gold Coast during the two
following annual wave events. This study suggests that the Gold Coast beaches
would not be able to withstand the impact of an increased frequency of extreme
events similar in scale to those of 1967.

the period 1987-2005: Impacts and lessons." Coastal Engineering 56(9): 940-950.
Erosion of the southern Gold Coast beaches (SE Queensland, Australia) was
exacerbated after the extension of the Tweed River training walls in the early
1960s. To achieve the objective of restoring and maintaining beach amenity,
significant nourishment works have been undertaken in Coolangatta Bay over the
past 30 years. Particularly, under the Tweed River Entrance Sand Bypassing
Project (TRESBP) since 1995, a number of nourishment campaigns and the
implementation of a permanent sand bypass system in 2001 have resulted in
significant changes of Coolangatta Bay morphology. The present case study
investigates the influence of both wave climate and nourishment works on the
area extending from the updrift Snapper Rocks area to downdrift Kirra Beach.
SWAN spectral wave model is implemented at Coolangatta Bay area and forced
by the global wave model WW3 to estimate wave forcing and the potential
natural longshore drift entering in Coolangatta. Specific transects extracted from
accurate bathymetric surveys are used to investigate and quantify Coolangatta
Bay sedimentation for the period 1987-2005. A network of Argus video stations
provides high sample rate information on the shoreline evolution. Results show
that, over the past 10 years, Coolangatta Bay has infilled rapidly. Sedimentation
reached up to 6 m in some areas between 1995 and 2005, with beach width
increasing by 200 m at Kirra Beach. Rapid seaward shoreline migration is
consistent with the intense over-pumping of sand relative to the natural potential
to move sand alongshore. The nourishment strategy used during this project has
successfully delivered large amounts of sand to the southern Gold Coast
embayment, although it has been up to now controversial from many community
perspectives. The artificial sand bypassing process proved to be much more
efficient than depositing the dredged sand in the nearshore area which requires a
significant period of low energy condition in order for the deposited sediment to
migrate shoreward and weld to the shore. This case study confirms that, when
carefully undertaken, sand bypassing is a sustainable and flexible soft
engineering approach which can work in concert with natural processes.

climate signals." Austral Ecology 35(8): 969-979.
Temporal and climate-related changes in avian phenology were assessed for
seven species of south-eastern Australia using data obtained from members of
the public, naturalist groups and other organizations. Despite significantly warmer
temperatures (∼0.02–0.03°C per year) and reduced rainfall (∼1.6–8.0 mm per
year) over much of south-eastern Australia in recent decades, most species
showed no corresponding trends in their timing of migration or breeding, the
notable exceptions being the grey fantail (Rhipidura fuliginosa) and the flame
robin (Petroica phoenicea), which migrate through Melbourne, Victoria, during
autumn and spring. In many species, however, migration or breeding timing
appeared to be influenced to some extent by local, rather than regional, climate
conditions, particularly local daily maximum and minimum temperatures. Whether
these species will noticeably change their phenology to match projected changes
in climate, perhaps when a currently unknown climate threshold is crossed, or
whether these species are sufficiently flexible in their foraging strategies or food
sources to be able to maintain their current timing, remains to be seen

The optically stimulated luminescence (OSL) dating method was used to
determine the geochronology of seven relict beach ridges that sit immediately
behind the modern beach at Beachmere, a low-energy sandy coast within
Moreton Bay, Queensland. Between 2600 ± 400 and 1700 ± 130 years ago,
the shoreline eroded and foreshore sediment was deposited over the older beach
deposit. Subsequently, there was a 1500-year period of shoreline progradation:
the shoreline advanced 0.16 m/y between 1700 ± 130 and 1140 ± 80 years
ago; and 0.41 m/y between 1140 ± 80 and around 200 years ago. Shortly after
690 ± 60 years ago, a series of well-developed regularly spaced beach ridges
gave way to an intertidal flat and then deposition of a set of lower amplitude,
closely spaced beach ridges. The younger ridges were deposited between 230
± 40 and 140 ± 50 years ago, at a rate of around 1.06 m/y. During the last
several decades, much of the Beachmere shoreline has eroded into these
younger relict ridges. Drivers of these changes in shoreline sedimentary regime
are yet to be accurately determined; however, it seems likely they are related to
switches that occur in the nearshore sand transport pathway. Our results
demonstrate the utility of the OSL method for providing insights into coastal
change that occurred in the historical and recent geological period. Better
understanding the tempo of shoreline change in the recent past is particularly
relevant for assessments of vulnerability to erosion of rapidly developing,
low-lying sandy coasts such as northern Moreton Bay. [PUBLICATION

Rocky shores occur at the interface of the land and sea. Typically they are open
ecosystems, with steep environmental gradients. Their accessibility to man has
rendered them susceptible to a variety of impacts since prehistoric times. Access
can be regulated, however, and they are more amenable to management than
open ocean habitats. This review uses examples from throughout the world to
demonstrate the extent to which rocky shores have been, and are currently,
affected by pollution (examples used are endocrine disrupters, oil,
eutrophication), over-collection of living resources, introduced alien species,
modification of coastal processes (coastal defences, siltation) and global change
(climate, sea level). These impacts are put into the context of natural fluctuations
in time and variability in space of both the environment and the organisms. The
relative magnitudes of some anthropogenic disturbances differ between the
industrialized, developed world and the developing world. For example, in
developed, industrialized countries pollution based impacts should diminish over
the next 25 years due to improved regulation and a reduction in older 'dirtier'
heavy industry. Conversely, in many developing countries pollution will increase
as a consequence of growth in the human population and industrialization.
Except for large-scale disasters such as oil spills, pollution tends mainly to
influence embayed coastlines. Chronic effects such as eutrophication can have
broader-scale impacts over whole coastlines and elevated nutrient levels have
also been implicated in a trend of increasing frequency of catastrophic kills due to
harmful algal. Direct removal of living resources has had major effects on
coastlines at both local and regional scales and is likely to increase over the next
25 years, especially in developing countries where rapidly expanding human
populations will put further pressure on resources. Impacts from recreational
activities are likely to increase with greater leisure time in wealthier regions of the
world, and cheaper travel will spread these impacts to poorer regions. Invasions
by alien species have increased in frequency during the last 20 years leading to
some dramatic effects on native assemblages. Problems associated with alien
species, especially pathogens, will continue to increase over the next few
decades. The proportion of the coastline modified by artificial structures
(breakwaters, seawalls, groynes) will increase because of coastal development
and defences against sea-level rise and the greater frequency of storms. This will
increase connectivity between areas of rocky habitat. Siltation will continue to
increase due to urbanization of catchments and estuaries, and changes in
agricultural practice. This may have considerable impacts at local and regional
scales, favouring sediment tolerant organisms such as turf algae and anemones.
In the future, greater frequency of environmental extremes is likely, including
large-scale events such as the El Nino Southern Oscillation (ENSO). Global
change in temperature, sea-level rise and increases in the frequency of storms
will affect rocky shores throughout the world, but this will occur over long time
scales; over the next 25 years most of the responses by rocky shore
communities will mostly be quite subtle. Thus rocky shores will be subject to
increasing degradation over the next 25 years. They are, however, less
vulnerable than many other aquatic habitats due to their hard substratum (rock),
their relative lack of large biogenic structures and to their generally open nature.
They are also remarkably resilient, and rec Their susceptibility to both terrestrial
and marine disturbances does make them more vulnerable than sublittoral and
offshore habitats. There are considerable gaps in knowledge, particularly of
certain microhabitats such as crevices, boulders, sand-scoured areas and rock
pools. These have been much less studied than more accessible assemblages
on open, freely draining rock. More research is needed to establish the effects of
increasing sediment loads, ultraviolet radiation and introduced species on rocky
shore communities. Strategic and applied research programmes should integrate
field experiments and carefully selected monitoring programmes to verify
management regimes. Hindcasting from the palaeo-record would be valuable, to
compare rates of predicted change with periods when change was rapid in the
past. This information could, in principle, be used to help conserve rocky shores
through networks of marine protected areas and a general reduction of
environmental pollution.

Ecology and Management 16(4): 255-276.
This review brings together information on mosquitoes, the diseases they
transmit and the wetlands that provide habitats for the immature stages (eggs
and larvae). Wetland values are mentioned, though the main literature on this
does not generally overlap the mosquito issue. Mosquito management is
overviewed to include: the use of larvicides, source reduction in intertidal
wetlands and management in freshwater systems. There is not a great deal of
information on mosquitoes and freshwater systems, except for constructed
wetlands and they are considered separately. We then consider restoration
mainly in the context of wetlands that have been the subject of habitat
modification for mosquito control. Land use and climate change, as they affect
mosquitoes and the diseases they transmit, are also reviewed, as this will affect
wetlands via management activities. Finally the review addresses the critical
issue of balancing health, both human and environmental, in an adaptive
framework. It concludes that there is a need to ensure that both mosquito and
wetland management communicate and integrate to sustain wetland and human
health.

to inform coastal management decisions: A research outline." Management of
Environmental Quality 20(4): 408.
Purpose - The purpose of this paper is to demonstrate the critical need for
economic information to inform the selection of coastal management options for
the beaches of the Sydney region and to outline the project currently under way
to address this information gap. Design/methodology/approach - The critical
need for the current case study is framed through presenting a summary of the
threats posed by current climate change projections, the legislative requirements
for economic valuation of natural resources, and the role which economics can
play in selection of appropriate coastal management options in response to
climate change impacts. Findings - The paper presents the valuation methods
that were selected for use in the Sydney Beaches Valuation Project and outlines
the rationale behind their selection. Originality/value - No current, empirical
estimates of the economic value of Sydney beaches are available, which means
that managers must use estimates from studies which may not reflect the unique
characteristics of either the Sydney beaches or the social context. The results of
the study, in terms of both unit measures of economic value and lessons learned
during the survey design process, will therefore be of great value to coastal
managers in the Sydney region. An external link provides details of the mixed
mode survey instrument, which can be used to inform the design of other similar
studies. Given the critical role of economic appraisal methods in selection of
coastal management alternatives, the survey structure is potentially of great use
to coastal managers in similarly threatened coastal locations elsewhere.

http://entweb.clemson.edu/database/trichopt/search.htm ], as at July 2006,
recorded 12,627 species, 610 genera and 46 families of extant and in addition
488 species, 78 genera and 7 families of fossil Trichoptera. An analysis of the
2001 TWC list of present-day Trichoptera diversity at species,
generic/subgeneric and family level along the selected Afrotropical, Neotropical,
Australian, Oriental, Nearctic and Palaearctic (as a unit or assessed as Eastern
and Western) regions reveals uneven distribution patterns. The Oriental and
Neotropical are the two most species diverse with 47â€―77% of the species in
widespread genera being recorded in these two regions. Five Trichoptera
families comprise 55% of the world’s species and 19 families contain fewer
than 30 species per family. Ten out of 620 genera contain 29% of the world’s
known species. Considerable underestimates of Trichoptera diversity for certain
regions are recognised. Historical processes in Trichoptera evolution dating back
to the middle and late Triassic reveal that the major phylogenetic differentiation in
Trichoptera had occurred during the Jurrasic and early Cretaceous. The breakup
of Gondwana in the Cretaceous led to further isolation and diversification of
Trichoptera. High species endemism is noted to be in tropical or mountainous
regions correlated with humid or high rainfall conditions. Repetitive patterns of
shared taxa between biogeographical regions suggest possible centres of origin,
vicariant events or distribution routes. Related taxa associations between
different regions suggest that an alternative biogeographical map reflecting
Trichoptera distribution patterns different from the Wallace (The Geographical
Distribution of Animals: With a Study of the Relations of Living and Extinct
Faunas as Elucidating the Past Changes of the Earth’s Surface, Vol. 1, 503
pp., Vol. 2, 607 pp., Macmillan, London, 1876) proposed biogeography patterns
should be considered. Anthropogenic development threatens biodiversity and the
value of Trichoptera as important functional components of aquatic ecosystems,
indicator species of deteriorating conditions and custodians of environmental
protection are realised.

Conversion of natural habitats into agricultural and industrial landscapes, and
ultimately into degraded land, is the major impact of humans on the natural
environment, posing a great threat to biodiversity. The emerging discipline of
restoration ecology provides a powerful suite of tools for speeding the recovery of
degraded lands. In doing so, restoration ecology provides a crucial complement
to the establishment of nature reserves as a way of increasing land for the
preservation of biodiversity. An integrated understanding of how human
population growth and changes in agricultural practice interact with natural
recovery processes and restoration ecology provides some hope for the future of
the environment.

Intermittently open/closed coastal lakes and lagoons are susceptible to
contamination and nutrient-enrichment. Although many of them are considered to
be degraded, our understanding of their ecology and the effects of anthropogenic
activity is limited. This study of coastal lakes in New South Wales compared the
density and distribution of macrobenthos in localities that differed in their degree
of isolation from the sea, that is, open versus closed lakes and mouths versus
inner reaches. Lakes kept open artificially (to improve water quality and reduce
flooding), were also compared with naturally open or closed lakes. Densities of
macrobenthos were usually greater in the mouths of open than of closed lakes,
but the opposite was true in inner reaches. While isolated localities differed more
between lakes than did mouths, small-scale variability was greater in the latter.
Spatial patterns were less temporally consistent in inner reaches than in mouths.
Differences in densities and spatial variability between mouths and inner reaches
were influenced primarily by whether a lake was open or closed and secondarily
by manipulation of the mouth. While, for example, densities in open manipulated
systems were usually greater in the mouths, but smaller in the inner reaches, the
effect of manipulation was less obvious in closed lakes. Differences in density
between types of lakes were not clearly related to physical factors although,
within lakes, benthos generally correlated negatively with salinity and positively
with median particle-size, silt and organic content. The effects of factors that
modify the degree of isolation of coastal lakes are discussed and it is concluded
that current levels of isolation do not appear to affect macrobenthos adversely.
Nevertheless, increased isolation, which is likely as a result of climatic change,
may well do so, particularly in lakes already stressed by human impacts.

Beach, Western Australia." Journal of Coastal Research 22(1): 63-77.
The morphology of Como Beach in the Swan River Estuary, Western Australia, is
described. Como Beach is in a microtidal estuarine environment in which modal
wave conditions are extremely low and nontidal fluctuations in water level are
principally determined by storm surges and low-frequency changes in ocean
water levels. Detailed descriptions of sandy beaches in very sheltered locations,
such as Como, are uncommon in the literature, although these beaches are a
common feature of coastal environments. In contrast to beaches in
wave-dominated environments, those in very sheltered, low-energy locations
may support subtidal terraces and beach profiles that differ in form and scale
from the bars and intertidal flats in wave- and tide-dominated environments. At
Como, beach profiles are superimposed on a subtidal terrace rising steeply from
waters several metres deep to -1.5 m (Australian Height Datum; AHD), then with
a low gradient to approximately -0.3 m (AHD) at the shore. The profiles range
from planar forms on which very small waves (H^sub b^ less than 0.1 m) are
dissipated to curvilinear forms that reflect higher waves (H^sub b^ > 0.2 m) from
the beachface. A transitional form with a segmented profile comprising a steep
beachface and flat inshore occurs, particularly where littoral drift is apparent.

in a changing world." Wetlands Ecology and Management 17(1): 71-84.
Global climate change is recognized as a threat to species survival and the
health of natural systems. Scientists worldwide are looking at the ecological and
hydrological impacts resulting from climate change. Climate change will make
future efforts to restore and manage wetlands more complex. Wetland systems
are vulnerable to changes in quantity and quality of their water supply, and it is
expected that climate change will have a pronounced effect on wetlands through
alterations in hydrological regimes with great global variability. Wetland habitat
responses to climate change and the implications for restoration will be realized
differently on a regional and mega-watershed level, making it important to
recognize that specific restoration and management plans will require
examination by habitat. Floodplains, mangroves, seagrasses, saltmarshes, arctic
wetlands, peatlands, freshwater marshes and forests are very diverse habitats,
with different stressors and hence different management and restoration
techniques are needed. The Sundarban (Bangladesh and India), Mekong river
delta (Vietnam), and southern Ontario (Canada) are examples of major wetland
complexes where the effects of climate change are evolving in different ways.
Thus, successful long term restoration and management of these systems will
hinge on how we choose to respond to the effects of climate change. How will we
choose priorities for restoration and research? Will enough water be available to
rehabilitate currently damaged, water-starved wetland ecosystems? This is a
policy paper originally produced at the request of the Ramsar Convention on
Wetlands and incorporates opinion, interpretation and scientific-based
arguments.
Everts, C. H., B. G. Thom, et al. (2006). "Management of Uncertainty in Predicting
Climate-Change Impacts on Beaches." Journal of Coastal Research 22(1): 232-245.
Management of uncertainty in model predictions of long-term coastal change
begins by admitting uncertainty. In the case of geometric mass-balance models,
the first step is to relax restrictive assumptions to allow for open sediment
budgets, time-dependent morphology, effects of mixed sediment sizes, and
variable resistance in substrate material. These refinements introduce new
uncertainty regarding the choice of parameter values. The next step is to actively
manage uncertainty using techniques readily available from information science.
The final step requires a shift in coastal management culture to accept decision
making based on risk-management protocols. Stochastic simulation was applied
to manage predictive uncertainty in cases involving complications resulting from
open sediment budgets, rock reefs, and seawalls. In these examples, the
respective effects caused between 20% and 60% difference from conventional
predictions based solely on equilibrium assumptions and substrates comprised
entirely of sand. Stochastic simulation makes it possible to establish confidence
limits and determine the statistical significance of differences caused by varying
effects such as substrate resistance and shoreface geometry. It also enables the
likelihood of critical impacts to be specified in terms of probability. Moreover,
probabilistic forecasts provide a transparent basis for coastal management
decisions by revealing the consequences if quantitative estimates prove to be
wrong. [PUBLICATION ABSTRACT]

Aims Despite the biodiversity values of the freshwater floodplains of northern
Australia being widely recognized, there has not been a concomitant investment
in developing the extent of knowledge of the basic functions and ecological
processes that underpin the ecological character of these habitats. This review
addresses the extent of our knowledge on the plant ecology of these wetlands
and covers: the relationships between the climate and the hydrological regime on
the floodplain; the vegetation patterns, succession and adaptation; and primary
production. Scope Information is available on the seasonal, but less regularly on
the inter-annual, dynamics of the macrophytic vegetation and its evident
inter-relationship with the extent, depth and duration of inundation by seasonal
flooding. The available scientifically collected information on plant distribution and
relationship with the water regime could be complemented by more attention to
traditional knowledge. The productivity of the vegetation is high-the dominant
wetland grass species have an annual dry weight production of 0.5-2.1 kg m(-2)
and the surrounding riparian (Melaleuca) trees contribute litterfall of 0.7-1.5 kg
(dry weight) m(-2) year(-1), similar to 70 % due to leaf-fall. The availability of
dissolved oxygen in the water is known to vary diurnally and seasonally, at least
in some habitats. The importance of seasonal differences in the availability of
dissolved oxygen for the growth of micro- and macrophytic vegetation has not
been investigated. The seasonal distribution and growth of plant species on a
few floodplains have been investigated, and maps at scales of 1 : 10 000 to 1 :
100 000 are available for these. However, only on a few occasions have longer
term analyses been conducted and long-term changes in the vegetation
measured and assessed. Species lists and categorization of growth strategies
and forms are available and provide a basis for further ecological investigation.
Conclusions Despite the large investment in managing the many pressures that
have degraded the ecological character of these highly valued wetlands, the
fundamental ecological processes that underpin the biodiversity values have not
received the same level of attention. Further information on plant growth and the
environmental factors that drive seasonal and annual changes in vegetation
distribution and productivity is required to assist managers in attending to
changes due to increasing invasive species and changes in fire regimes.

Freiberg, M. and S. M. Turton (2007). "Importance of drought on the distribution of the
birds nest fern, Asplenium nidus, in the canopy of a lowland tropical rainforest in
north-eastern Australia." Austral Ecology 32(1): 70-76.
The birds nest fern, Asplenium nidus, contributes greatly to the epiphytic biomass
in the canopies of both south-east Asia and tropical north Queensland
rainforests. It is generally believed that their abundance and their capacity to
store water is an important feature for habitat fragmentation in the canopy. We
investigated the microclimate of A. nidus and the effects of severe drought
periods on the A. nidus population over a 20-year period, hypothesizing that
water availability is the most important factor controlling the population under
drought conditions. One of two neighbouring A. nidus plants of the same size and
age was irrigated artificially before, during and after a significant dry period in
2000. By monitoring the microclimate within and around both ferns we were able
to estimate that four continuous weeks of rainless weather completely dried out
the accumulated humus of the non-irrigated A. nidus fern. Prolonged dry periods
were shown to kill the roots of A. nidus, which attach the fern to the bark and
eventually the affected A. nidus on verticals stems fell to the ground. Periods
longer than 8 weeks may even kill adult plants sitting in more protected branch
forks. Analysis of the whole A. nidus population within the 1-ha Canopy Crane
plot and the determination of the morphological age of all plants enabled an
evaluation of the historical development of the population. The oldest plant
originated in 1985, just 1 year after the longest recorded drought for the site. We
suspect that the 1984 drought killed every A. nidus plant within the study plot.
Years with low recruitment coincide with years with long drought periods.
Studies in the Neotropics (Freiberg 1997, 2001; Freiberg & Freiberg 2000) have shown
that canopy epiphytes and their accumulated dead organic matter (ramosphere)
reflect the microclimatic conditions of the forest floor suspended within a much
drier and warmer environment of the aerosphere (Freiberg 1996). A study in
Sabah (Ellwood et al. 2002) of Asplenium nidus in the canopy showed that this
species contributes about one tonne of dry mass per hectare and may hold up to
93% of the total number of invertebrates in the crown. The physiology of A. nidus
was investigated in detail in Singapore (Kluge et al. 1989) and although the
duration of the longest drought period was just 5 days, it has been hypothesized
that A. nidus is a stress tolerant plant that stores enough water in its root-debris
system to overcome periods of drought. The apical meristem of A. nidus is well
protected in a fur of scaly hairs. Falling leaf litter and other material accumulate
inside the basket and between the leaves and roots of the A. nidus creating a
suspended organic soil. The fleshy rhizome of A. nidus may reach a diameter of
up to 6 cm in adult plants and is probably an additional store of water in the dry
season. The physiological adaptations to drought of this pure C3 plant are not
known (carbon dioxide ratio δ13C of −26.8‰, Kluge et al. 1989; Holtum & Winter
1999). While A. nidus is also the most common epiphyte in the tropical areas of
north-eastern Australia, the climate of this region is rather different from Sabah
and Singapore with drought periods of several weeks not uncommon due to the
strongly seasonal rainfall regime (Tracey 1982). The Intergovernmental Panel on
Climate Change (IPCC 1996) predicts even more prolonged dry seasons for
north-eastern Australia by the end of the 21st century (Meehl 1997). In order to
predict the influence of an increase in drought length on the survival and
recruitment of the epiphytic vegetation in tropical rainforests, we investigate the
response of A. nidus to drought under natural conditions. By estimating the age
of individual plants and by using historical climate data it was possible to
determine what drought characteristics are important for the A. nidus population
at the study site. We also conducted a dry season field experiment on two
adjacent A. nidus plants, where one plant was artificially irrigated and the other
was left exposed to ambient weather conditions.

Austral Ecology 32(6): 669-685.
Abstract As urban areas continue to expand and replace natural and
agricultural landscapes, the ability to manage and conserve native wildlife within
urban environments is becoming increasingly important. To do so we first need to
understand species' responses to local-level habitat attributes in order to inform
the decision-making process and on-ground conservation actions. Patterns in the
occurrence of native terrestrial reptile and small mammal species in 59 sites
located in remnant urban habitat fragments of Brisbane City were assessed
against local-level environmental characteristics of each site. Cluster analysis,
multidimensional scaling ordination, and principal axis correlation were used to
investigate relationships between species' occurrences and environmental
characteristics. Native reptiles were most strongly associated with the presence
of termite mounds, a high amount of fallen woody material, and a moderate
amount of weed cover. Native small mammals were most strongly associated
with the presence of grass trees (Xanthorrhoea spp.), and both reptiles and small
mammals were negatively influenced by increased soil compaction. Significant
floristic characteristics were considered to be important as structural, rather than
compositional, habitat elements. Therefore, habitat structure, rather than
vegetation composition, appears to be most important for determining native,
terrestrial reptile and small mammal species assemblages in urban forest
fragments. We discuss the management implications in relation to human
disturbances and local-level management of urban remnants.

coastal lakes, southeastern South Australia." Hydrobiologia 591(1): 165-183.
Diatom analyses of sediment cores extracted from three lakes in coastal
southeastern South Australia reveal that, for most of the mid-late Holocene, they
were shallow, brackish to saline systems with limited flow of water from
continental sources. The construction of a substantial network of drains in the
early years of settlement, to maximise transportation and agricultural production
through wet winters, lead to abrupt freshening of the lakes. Interestingly, despite
substantial nutrient loads to Lake Bonney SE (there are two Lakes Bonney and
Frome in South Australia, which is why the lakes in the southeast of the state are
differentiated with ‘SE’) associated with the commissioning and expansion
of pulp and paper mills, a wastewater treatment plant discharge and agricultural
runoff, there is only moderate evidence of nutrient enrichment in the lake,
possibly because the post-impact assemblages are dominated by taxa with
broad ecological preferences. Despite being preserved within a conservation
park, eutrophication associated with agriculture is evident in the diatom
assemblages of Lake Frome SE, which has a catchment more than twice that of
Lake Bonney SE. Mullins Swamp, on the other hand, supports few indicators of
eutrophic conditions. The freshening of these lakes is against the tide of
salinisation from rising saline groundwaters in most wetlands across
southeastern Australia.

of Eastern and Southern Australia." Journal of Coastal Research 23(4): 899-910.
Macrofaunal communities of beaches in eastern Australia were investigated for
relationships of species number, abundance, and biomass with the physical
characteristics of the beach environment (expressed numerically as the
dimensionless fall velocity and beach state index [BSI]). A range of physical
beach states across three biogeographical regions was sampled for macrofauna
at low tide during summer months, and the data were regressed and compared.
Results showed that species number, abundance, and biomass increased from
reflective to ultradissipative shore conditions (abundance and biomass increasing
logarithmically). Species number showed the same numerical relationship with
BSI for each of the regions studied, the common regression equation showing
that nearly 90% of variation in macrofaunal species number between beaches
can be explained by this compound index of physical parameters. Abundance
and biomass showed similarities in response to BSI, although at different orders
of magnitude by region. The results of a multiple regression including latitude
suggest that, although species richness is almost directly related to physical
beach processes, abundance and biomass are determined more by a
combination of surf zone processes and climatic factors specific to each
biogeographic region. [PUBLICATION ABSTRACT]
Hancock, T. E. (2009). Ecophysiology of barrier island beach plants: Responses in form
and function to daily, seasonal and episodic stresses.
Barrier islands (BIs) are transient, highly dynamic geological structures of fairly
recent origin found along most continental shorelines. The small suite of plant
species that survive in this habitat have been the subject of numerous ecological
studies for greater than one-hundred years. Unfortunately, research on the
physiological ecology of BI beach plants is essentially nonexistent. The most
general objective of this dissertation is to incorporate the tools of physiological
ecology into an ecological study that investigates the response of four plant
species representing different functional groups to daily, seasonal and episodic
stresses present on Topsail Island, North Carolina (USA).

assessment." Sustainability Science 3(1): 67-87.
The Australian coastline is one of the longest and most diverse of any in the
world, and Australian researchers have developed preliminary models of the
behaviour of major coastal systems such as beaches and reefs. The Australian
population is particularly focused along the coastline, especially in metropolitan
centres; however, the population of regional centres along the coast is increasing
steadily in response to a phenomenon termed seachange. Coastal systems are
increasingly threatened by potential impacts as a result of climate change, as
indicated by the successive assessments by the Intergovernmental Panel on
Climate Change (IPCC). Although Australia played a central role in applying a
common methodology (CM), developed from IPCC guidelines in the 1990s, and
in devising alternative approaches, which were initially trialled at nine sites on the
Australian coast, there has not been a nationally co-ordinated approach to
assessing the coastal vulnerability of Australia, and such an approach is only
emerging now. Instead, there have been a series of different approaches
adopted to look at the different parts of the Australian coast, including wetland
mapping in northern Australia; geomorphic unit mapping in South Australia;
storm surge vulnerability modelling in Queensland; probabilistic approaches to
beach erosion in New South Wales; indicative mapping of potential coastal
retreat in Tasmania. Additionally, there have been methods proposed by insurers
and coastal engineers to meet their requirements. Since 2005, the Australian
government has once again seen the need for a national coastal vulnerability
assessment, and a series of studies are planned or under way to achieve the
aims of a National Climate Change Adaptation Framework.

Oscillation: implications for natural coastal resources and management." Helgoland
Marine Research 62(1): 5-14.
The El Nino Southern Oscillation (ENSO) significantly influences marine
ecosystems and the sustained exploitation of marine resources in the coastal
zone of the Humboldt Current upwelling system. Both its warm (El Niño: EN)
and cold (La Niña: LN) phase have drastic implications for the ecology,
socio-economy and infrastructure along most of Pacific South America. Local
artisanal fisheries, which especially suffer from the effects of EN, represent a
major part for the domestic economy of Chile and Peru and in consequence a
huge amount of published and unpublished studies exists aiming at identifying
effects of EN and LN. However, most processes and underlying mechanisms
fostering the ecology of organisms along Pacific South America have not been
analyzed yet and for the marine realm most knowledge is traditionally based on
rather descriptive approaches. We herein advocate that small-scale comparative
and interdisciplinary process studies work as one possible solution to understand
better the variability observed in EN/LN effects at local scale. We propose that
differences in small-scale impacts of ENSO along the coast rather than the
macro-ecological and oceanographic view are essential for the sustainable
management of costal ecosystems and the livelihood of the people depending on
it. Based on this, we summarize the conceptual approach from the EU-funded
International Science and Technology Cooperation (INCO) project “Climate
variability and El Niño Southern Oscillation: Implications for Natural Coastal
Resources and Management (CENSOR)― that aims at enhancing the
detection, compilation, and understanding of EN and LN effects on the coastal
zone and its natural resources. We promote a multidisciplinary avenue within
present international funding schemes, with the intention to bridge the traditional
gap between basic and applied coastal research. The long-term aim is an
increased mitigation of harm caused by EN as well as a better use of beneficial
effects, with the possibility to improve the livelihood of human coastal populations
along Pacific South America and taking differences between local
socio-economic structures of the countries affected by EN into consideration. The
success of such an approach however, does finally rely upon a willingness of the
recourse users and the various political and economic stakeholders involved to
taking on the message as part of sustainable management strategies.

Climate Research 37(2-3): 123-133.
Warming of the planet has accelerated in recent years and is predicted to
continue over the next 50 to 100 yr. Evidence of responses to present warming in
marine ecosystems include Shifts in the geographic range of species as well as
in the composition of pelagic and demersal fish, benthic and intertidal
assemblages, Here we provide a review of the changes, in geographic
distributions and population abundance of species detected on rocky shores of
the NE Atlantic over the last 60 yr. This period encompassed the warm 1950s, a
colder period between 1963 and the late 1980s and the recent period of
accelerating warming to levels above those of the 1950s. The likely
consequences of these responses are then explored. To do this, a summary of
the dynamic balance between grazers, macroalgae and barnacles in structuring
mid-shore communities is given before outlining experimental work on
interactions between key components of rocky shore communities. Modelling and
quantitative forecasting were used to predict changes in community composition
and dynamics in a warmer world and their consequences for ecosystem
functioning discussed. We then identify areas that need further work before
making a case for the use of rocky shore species not just as inexpensive
indicators of change offshore, but as tractable models to explore the direct and
indirect effects of climate change in marine and coastal ecosystems, We also
provide a societal perspective emphasising the value of long-term Studies in
informing adaptation to climate change.

change in the humid tropics of north Queensland." Austral Ecology 26(6): 590-603.
An analysis using an artificial neural network model suggests that the tropical
forests of north Queensland are highly sensitive to climate change within the
range that is likely to occur in the next 50–100 years. The distribution and extent
of environments suitable for 15 structural forest types were estimated, using the
model, in 10 climate scenarios that include warming up to 1°C and altered
precipitation from –10% to +20%. Large changes in the distribution of forest
environments are predicted with even minor climate change. Increased
precipitation favours some rainforest types, whereas decreased rainfall increases
the area suitable for forests dominated by sclerophyllous genera such as
Eucalyptus and Allocasuarina. Rainforest environments respond differentially to
increased temperature. The area of lowland mesophyll vine forest environments
increases with warming, whereas upland complex notophyll vine forest
environments respond either positively or negatively to temperature, depending
on precipitation. Highland rainforest environments (simple notophyll and simple
microphyll vine fern forests and thickets), the habitat for many of the region‘s
endemic vertebrates, decrease by 50% with only a 1°C warming. Estimates of
the stress to present forests resulting from spatial shifts of forest environments
(assuming no change in the present forest distributions) indicate that several
forest types would be highly stressed by a 1°C warming and most are sensitive to
any change in rainfall. Most forests will experience climates in the near future
that are more appropriate to some other structural forest type. Thus, the
propensity for ecological change in the region is high and, in the long term,
significant shifts in the extent and spatial distribution of forests are likely. A
detailed spatial analysis of the sensitivity to climate change indicates that the
strongest effects of climate change will be experienced at boundaries between
forest classes and in ecotonal communities between rainforest and open
woodland.

California: The Role of Beach Grooming." Estuaries and Coasts 33(1): 67-77.
We investigated the role of beach grooming in the loss of coastal strand
ecosystems. On groomed beaches, unvegetated dry sand zones were four times
wider, macrophyte wrack cover was >9 times lower, and native plant abundance
and richness were 15 and >3 times lower, respectively, compared to ungroomed
beaches. Experimental comparisons of native plant performance were consistent
with our survey results: although initial germination was similar, seed bank,
survival, and reproduction were significantly lower in groomed compared to
ungroomed plots. Rates of aeolian sand transport were significantly higher in
groomed plots, while native plants or wrack placed in that zone reduced sand
transport. Our results suggest beach grooming has contributed to widespread
conversion of coastal strand ecosystems to unvegetated sand. Increased
conservation of these threatened coastal ecosystems could help retain sediment,
promote the formation of dunes, and maintain biodiversity, wildlife, and human
use in the face of rising sea levels.

Macrobenthic Assemblages on Sandy Beaches." Environmental Management 41(6):
878-892.
Sandy beaches are the prime sites for human recreation and underpin many
coastal economies and developments. In many coastal areas worldwide, beach
recreation relies on the use of off-road vehicles (ORVs) driven on the shore. Yet,
the use of ORVs is not universally embraced due to social conflicts with other
beach user groups and putative environmental consequences of vehicle traffic on
sandy shores. Such ecological impacts of ORVs are, however, poorly understood
for endobenthic invertebrates of the intertidal zone seawards of the dunes.
Consequently, this study quantified the degree to which assemblages of intertidal
beach invertebrates are affected by traffic. The study design comprised a series
of temporally replicated spatial contrasts between two reference sites (no ORVs)
and two beaches with heavy ORV traffic (in excess of 250,000 vehicles per year)
located in South-East Queensland, Australia. Macrobenthic assemblages on
ORV-impacted beaches had significantly fewer species at substantially reduced
densities, resulting in marked shifts in community composition and structure.
These shifts were particularly strong on the middle and upper shore where
vehicle traffic was concentrated. Strong effects of ORVs were detectable in all
seasons, but increased towards the summer months as a result of heavier traffic
volumes. This study provides clear evidence that ORVs can have substantial
impacts on sandy beach invertebrates that are manifested throughout the whole
community. Demonstrating such an ecological impact caused by a single type of
human use poses a formidable challenge to management, which needs to
develop multi-faceted approaches to balance environmental, social, cultural, and
economic arguments in the use of sandy shores, including management of
"beach traffic." (PUBLICATION ABSTRACT)

resilience and future; R.S. Steneck et al.; Kelp forest ecosystems." Environmental
Conservation 29(4): 436.
Kelp forests are phyletically diverse, structurally complex and highly productive
components of coldwater rocky marine coastlines. This paper reviews the
conditions in which kelp forests develop globally and where, why and at what rate
they become deforested. The ecology and long archaeological history of kelp
forests are examined through case studies from southern California, the Aleutian
Islands and the western North Atlantic, well-studied locations that represent the
widest possible range in kelp forest biodiversity. Global distribution of kelp forests
is physiologically constrained by light at high latitudes and by nutrients, warm
temperatures and other macrophytes at low latitudes. Within mid-latitude belts
(roughly 40-60° latitude in both hemispheres) well-developed kelp forests are
most threatened by herbivory, usually from sea urchins. Overfishing and
extirpation of highly valued vertebrate apex predators often triggered herbivore
population increases, leading to widespread kelp deforestation. Such
deforestations have the most profound and lasting impacts on
species-depauperate systems, such as those in Alaska and the western North
Atlantic. Globally urchin-induced deforestation has been increasing over the past
2-3 decades. Continued fishing down of coastal food webs has resulted in
shifting harvesting targets from apex predators to their invertebrate prey,
including kelp-grazing herbivores. The recent global expansion of sea urchin
harvesting has led to the widespread extirpation of this herbivore, and kelp
forests have returned in some locations but, for the first time, these forests are
devoid of vertebrate apex predators. In the western North Atlantic, large
predatory crabs have recently filled this void and they have become the new
apex predator in this system. Similar shifts from fish- to crab-dominance may
have occurred in coastal zones of the United Kingdom and Japan, where large
predatory finfish were extirpated long ago. Three North American case studies of
kelp forests were examined to determine their long history with humans and
project the status of future kelp forests to the year 2025. Fishing impacts on kelp
forest systems have been both profound and much longer in duration than
previously thought. Archaeological data suggest that coastal peoples exploited
kelp forest organisms for thousands of years, occasionally resulting in localized
losses of apex predators, outbreaks of sea urchin populations and probably
small-scale deforestation. Over the past two centuries, commercial exploitation
for export led to the extirpation of sea urchin predators, such as the sea otter in
the North Pacific and predatory fishes like the cod in the North Atlantic. The
large-scale removal of predators for export markets increased sea urchin
abundances and promoted the decline of kelp forests over vast areas. Despite
southern California having one of the longest known associations with coastal
kelp forests, widespread deforestation is rare. It is possible that functional
redundancies among predators and herbivores make this most diverse system
most stable. Such biodiverse kelp forests may also resist invasion from
non-native species. In the species-depauperate western North Atlantic,
introduced algal competitors carpet the benthos and threaten future kelp
dominance. There, other non-native herbivores and predators have become
established and dominant components of this system. Climate changes have had
measurable impacts on kelp forest ecosystems and efforts to control the
emission of greenhouse gasses should be a global priority. However, overfishing
appears to be the greatest manageable threat to kelp forest ecosystems over the
2025 time horizon. Management should focus on minimizing fishing impacts and
restoring populations of functionally important species in these systems.

Abstract This study investigates the importance of climate as a factor influencing
the southern distributional limit of the common blossom bat (Syconycteris
australis). Using the climatic predictive model BIOCLIM and 73 locality records,
5. australis was predicted to have a coastal distribution in eastern Australia,
where winter temperatures are relatively warm and moist conditions prevail
throughout the year. The actual southern limit of S. australis, determined by
mist-netting suitable habitats, was found to be at Booti-Booti (32°19'S 152°3l'E)
on the mid-north coast of New South Wales. BIOCLIM predicted the southerly
limit of 5. australis to be 150–200km further south of their actual limit. Booti-Booti
was occupied at relatively low levels of abundance year round, while the
abundance of S. australis at a site 50 km to the north was much greater,
fluctuating with changes in Banksia flower numbers. Seasonal range extensions
beyond Booti-Booti were not detected, despite the availability of apparently
suitable habitat at Myall Lakes only 20–35 km further south. Metabolic costs of S.
australis at Booti-Booti were estimated to exceed basal metabolic rate (BMR) by
4.5 times, well above the physiologically predicted limit of 2.5 times BMR. These
results, together with the lack of range extensions and the close correspondence
of BIOCLIM'S predicted southern limit of S. australis with their actual limit,
suggest that the bat's southern distribution is limited by cold, wet winters and dry
summers

structure and function." Austral Ecology 31(2): 149-163.
Urbanization is a major cause of loss of coastal wetlands. Urbanization also
exerts significant influences on the structure and function of coastal wetlands,
mainly through modifying the hydrological and sedimentation regimes, and the
dynamics of nutrients and chemical pollutants. Natural coastal wetlands are
characterized by a hydrological regime comprising concentrated flow to estuarine
and coastal areas during flood events, and diffused discharge into groundwater
and waterways during the non-flood periods. Urbanization, through increasing
the amount of impervious areas in the catchment, results in a replacement of this
regime by concentrating rain run-off. Quality of run-off is also modified in urban
areas, as loadings of sediment, nutrients and pollutants are increased in urban
areas. While the effects of such modifications on the biota and the physical
environment have been relatively well studied, there is to date little information
on their impact at the ecosystem level. Methodological issues, such as a lack of
sufficient replication at the whole-habitat level, the lack of suitable indices of
urbanization and tools for assessing hydrological connectivity, have to be
overcome to allow the effects of urbanization to be assessed at the ecosystem
level. A functional model is presented to demonstrate the impact of urbanization
on coastal wetland structure and function.
Lees, B. (2006). "Timing and Formation of Coastal Dunes in Northern and Eastern
Australia." Journal of Coastal Research
22(1): 78-89.
This article revisits the debate about the processes of coastal dune initiation in
Australia. A review of the dates published so far on coastal dunes in Australia
indicates that these belong to identifiable process regions. Those to the north
and northeast seem to be largely derived from the deflation, at low sea levels, of
exposed deltaic sediments, which are subsequently reworked by episodes of
active transgressive dune development. In the southeast, the dunes, like other
coastal depositional features, are largely derived from the alongshore sediment
transport system, which is active along this coast at times of higher sea level.
Apart from during glacial maxima, episodes of dune transgression, where a
source is identifiable, seem to be initiated along the shoreline, strongly
suggesting that marine disturbance is the trigger. Although, in many cases, these
are also at times when climate is favourable to active transgressive dune
development, the eastern Cape York dune fields make it clear that this is not a
necessary condition.

ecosystems: a test of ghost crabs ( Ocypode spp.) as biological indicators on an urban
beach." Environmental Monitoring and Assessment 152(1): 413-424.
Sandy beaches comprise one of the most important coastal resources worldwide,
providing habitats to threatened vertebrates, supporting underappreciated
invertebrate biodiversity, and delivering crucial ecosystem services and
economic benefits to mankind. Monitoring of the natural resource condition of
sandy beaches and assessments of the ecological impacts of human disturbance
are, however, rare on sandy shores. Because a crucial step in developing beach
monitoring is to identify and test biological indicators, we evaluated the utility of
using population densities of ghost crabs (genus Ocypode) to measure how
beach biota respond to human pressures. Densities of crabsâ€‖estimated via
burrow countsâ€‖were quantified at two sites exposed to high and low levels of
human disturbance on an urban beach in eastern Australia. Human disturbance
consisted of pedestrian trampling and shoreline armouring which led to the loss
of dune habitat. Overall, crab numbers were halved in disturbed areas, but
contrasts between impact and control sites were not necessarily consistent over
time and varied between different levels of the shore: stronger and more
consistent effect sizes were recorded on the upper shore than further seawards.
In addition to lowering crab densities, human disturbance also caused shifts in
intertidal distributions, with a greater proportion of individuals occurring lower on
the shore in the impacted beach sections. The number of visible burrow openings
also changed in response to weather conditions (temperature and wind). We
demonstrate that spatial contrasts of burrow counts are broadly useful to indicate
the existence of a human-induced disturbance effect on urban beaches; we also
highlight a number of critical, hitherto unknown, issues in the application of this
monitoring technique; these encompass three broad dimensions: (1) a need for
standardised protocols; (2) unresolved causal links between observed patterns
and putative pressures; and (3) uncertainties of how organisms responds
specifically to both natural and human changes of environmental conditions on
sandy shores.

and threats." Environmental Conservation 29(2): 115-133.
This review examines the status of temperate-zone freshwater wetlands and
makes projections of how changes over the 2025 time horizon might affect their
biodiversity. The six geographic regions addressed are temperate areas of North
America, South America, northern Europe, northern Mediterranean, temperate
Russia, Mongolia, north-east China, Korea and Japan, and southern Australia
and New Zealand. Information from the recent technical literature, general
accounts in books, and some first-hand experience provided the basis for
describing major wetland types, their status and major threats. Loss of
biodiversity is a consequence both of a reduction in area and deterioration in
condition. The information base for either change is highly variable
geographically. Many countries lack accurate inventories, and for those with
inventories, classifications differ, thus making comparisons difficult. Factors
responsible for losses and degradation include diversions and damming of river
flows, disconnecting floodplain wetlands from flood flows, eutrophication,
contamination, grazing, harvests of plants and animals, global warming,
invasions of exotics, and the practices of filling, dyking and draining. In humid
regions, drainage of depressions and flats has eliminated large areas of
wetlands. In arid regions, irrigated agriculture directly competes with wetlands for
water. Eutrophication is widespread, which, together with effects of invasive
species, reduces biotic complexity. In northern Europe and the northern
Mediterranean, losses have been ongoing for hundreds of years, while losses in
North America accelerated during the 1950s through to the 1970s. In contrast,
areas such as China appear to be on the cusp of expanding drainage projects
and building impoundments that will eliminate and degrade freshwater wetlands.
Generalizations and trends gleaned from this paper should be considered only as
a starting point for developing world-scale data sets. One trend is that the more
industrialized countries are likely to conserve their already impacted, remaining
wetlands, while nations with less industrialization are now experiencing
accelerated losses, and may continue to do so for the next several decades.
Another observation is that countries with both protection and restoration
programmes do not necessarily enjoy a net increase in area and improvement in
condition. Consequently, both reductions in the rates of wetland loss and
increases in the rates of restoration are needed in tandem to achieve overall
improvements in wetland area and condition. [PUBLICATION ABSTRACT]

Progress in Physical Geography 23(1): 1-36.
The time span of the past few million years has been punctuated by many rapid
climate transitions, most of them on timescales of centuries to decades. The
most detailed information is available for the Younger Dryas-to-Holocene
stepwise change around 11 500 years ago, which seems to have occurred over a
few decades. The speed of this change is probably representative of similar but
less well studied climate transitions during the last few hundred thousand years.
These include sudden cold events (Heinrich events/stadials), warm events
(interstadials) and the beginning and ending of long warm phases, such as the
Eemian interglacial. Detailed analysis of terrestrial and marine records of climate
change will, however, be necessary before we can say confidently on what
timescale these events occurred; they almost certainly did not take longer than a
few centuries. Various mechanisms, involving changes in ocean circulation and
biotic productivity, changes in atmospheric concentrations of greenhouse gases
and haze particles, and changes in snow and ice cover, have been invoked to
explain sudden regional and global transitions. We do not know whether such
changes could occur in the near future as a result of human effects on climate.
Phenomena such as the Younger Dryas and Heinrich events might only occur in
a 'glacial' world with much larger ice sheets and more extensive sea-ice cover. A
major sudden cold event, however, did probably occur under global climate
conditions similar to those of the present, during the Eemian interglacial around
122 000 years ago. Less intensive, but significant rapid climate changes also
occurred during the present (Holocene) interglacial, with cold and dry phases
occurring on a 1500-year cycle, and with climate transitions on a
decade-to-century timescale. In the past few centuries, smaller transitions (such
as the ending of the Little Ice Age at about AD 1650) probably occurred over only
a few decades at most. All evidence indicates that long-term climate change
occurs in sudden jumps rather than incremental changes.
Masselink, G. (2001). "Seasonal changes in beach morphology along the sheltered
coastline of Perth, Western Australia." Marine Geology 172(3-4): 243-263.
Seasonal change in beach morphology is traditionally ascribed to a variation in
the incident wave energy level with calm conditions in summer resulting in wide
beaches with pronounced subaerial berms and energetic conditions in winter
causing narrow beaches with nearshore bar morphology. The coastline of Perth,
Western Australia, is characterised by a large seasonal variation in the incident
wave height and local beaches exhibit a distinct seasonal change in morphology.
However, these morphological changes are better explained by a seasonal
reversal in the littoral drift direction than by variations: in the incident wave
energy conditions. In summer, when northward sediment transport prevails due
to sea breeze activity, beaches located south of coastal structures, headlands or
rocky outcrops become wider due to the accumulation of sediment against the
obstacle. These beaches will subsequently erode in winter during storms when
the longshore sediment transport is toward the south. In contrast, beaches
located north of obstacles will become narrower during summer and wider during
winter. The usefulness of the dimensionless fall velocity Omega = H-b/w(s)T
(where H-b is the breaker height, w(s) is the sediment fall velocity and T is the
wave period) as a predictor of presence/absence of bar morphology and beach
type was investigated. It was found that Omega fluctuates around the threshold
of bar formation (Omega approximate to 1.5-2) over a variety of time scales
(daily, weekly, and seasonally). These temporal variations in Omega in
conjunction with the relatively low wave energy level that characterises the coast
negates the development of beach and nearshore morphology that is in
equilibrium with the hydrodynamic conditions. As a result, bar occurrence and
beach type can not be readily predicted using Omega along the Perth coast. (C)

Predicting the various responses of different species to changes in landscape
structure is a formidable challenge to landscape ecology. Based on expert
knowledge and landscape ecological theory, we develop five competing a priori
models for predicting the presence/absence of the Koala (Phascolarctos
cinereus) in Noosa Shire, south-east Queensland (Australia). A priori predictions
were nested within three levels of ecological organization: in situ (site level)
habitat (<1 ha), patch level (100 ha) and landscape level (100–1000 ha). To test
the models, Koala surveys and habitat surveys (n = 245) were conducted across
the habitat mosaic. After taking into account tree species preferences, the patch
and landscape context, and the neighbourhood effect of adjacent present sites,
we applied logistic regression and hierarchical partitioning analyses to rank the
alternative models and the explanatory variables. The strongest support was for
a multilevel model, with Koala presence best predicted by the proportion of the
landscape occupied by high quality habitat, the neighbourhood effect, the mean
nearest neighbour distance between forest patches, the density of forest patches
and the density of sealed roads. When tested against independent data (n = 105)
using a receiver operator characteristic curve, the multilevel model performed
moderately well. The study is consistent with recent assertions that habitat loss is
the major driver of population decline, however, landscape configuration and
roads have an important effect that needs to be incorporated into Koala
conservation strategies.

Managing Climate Change And Variability To Avoid Ecosystem Collapse
." Currrent opinion and environmental sustainability.
―Climate change policies currently focus on reducing the concentration of
atmospheric greenhouse gases, but pay limited attention to feedbacks between
the land surface and the climate system. Forests and woodlands play an
important role in the climate system by buffering climate extremes, maintaining
the hydrological cycle and sequestering carbon. To reduce the potential impact of
climate variability and change on society and the environment, therefore,
requires a broader focus of environmental sustainability and resilience that is
underpinned by the restoration of feedbacks between vegetation and climate. We
urge a stronger integration of land use and climate change policies, a virtual halt
to all deforestation, and an acceleration of investment in strategic reforestation,
especially in tropical and sub-tropical regions, supported by a comprehensive
global forest monitoring program. Without these actions, the degradation of the
Earth‘s ecosystems will continue exacerbated by, and exacerbating, variability
and changes in temperature, precipitation and extreme weather events.‖

habitat networks in Queensland, Australia." Pacific Conservation Biology 15(2): 96.
Estuaries are widely recognized as key habitats supporting nearshore secondary
production and catch of commercial fisheries. In Queensland, some of these
coastal marine habitats are protected by the declared fish habitat programme run
by the Department of Primary Industries and Fisheries. Expected environmental
changes for Australian estuarine systems include reduced freshwater flow,
increased sedimentation and with them, a loss of connectivity. At present, the
relationship between the protected declared fish habitat and habitat connectivity
remains unknown. By comparing long term coastal fish catch data with
geomorphic characteristics of coastal habitats structural connectivity was
previously identified as a potential driver of commercial fish catch in Queensland.
An ecology landscape approach was used for this study to identify potential fish
habitat hotspots along the coastline of Queensland thus allowing better defined
networks of declared fish habitats. A comparison between this approach and the
current declared fish habitats demonstrated potential deficits and provided
important insights for fisheries management. Declared fish habitats should be
placed in coastal habitats with high structural connectivity to ensure sustainability
of fisheries in light of environmental changes. [PUBLICATION ABSTRACT]

28-36.
Beach nourishment is increasingly being implemented to address problems of
erosion. However, the ecological consequences of nourishment are poorly
understood, especially in Australia. In Botany Bay, sand was piped from an
intertidal borrow area at Elephant's Trunk to nourish the nearby eroding beach at
Towra Point. The effects on an intertidal exoedicerotid amphipod, Exoediceros
fossor (Stimpson, 1856), were examined using a beyond-BACI (Before-After,
Control-Impact) sampling design. Sampling was conducted before and after
engineering operations at sites within the borrow and nourishment locations and
multiple control locations. Hypotheses concerning impact and recovery were
tested using asymmetrical ANOVAs and two-tailed F-tests. These examined the
effects on abundance and spatial variability, respectively. The impact of the
engineering operations on abundance was very large at both borrow and
nourishment locations. However, recovery started within several weeks and,
using space x time interactions as a criterion, appeared to be complete within a
year. This conclusion is made cautiously because of low statistical power and
because other criteria for recovery suggest that it was not complete at some
sites. As beach erosion is likely to increase in severity with rising sea levels and
greater storm surges associated with climate change, management authorities
will need a better understanding of the ecological effects of beach nourishment.

assessment: scenarios for integrated assessment." Sustainability Science 3(1): 89-102.
Coastal vulnerability assessments still focus mainly on sea-level rise, with less
attention paid to other dimensions of climate change. The influence of
non-climatic environmental change or socio-economic change is even less
considered, and is often completely ignored. Given that the profound coastal
changes of the twentieth century are likely to continue through the twenty-first
century, this is a major omission, which may overstate the importance of climate
change, and may also miss significant interactions of climate change with other
non-climate drivers. To better support climate and coastal management policy
development, more integrated assessments of climatic change in coastal areas
are required, including the significant non-climatic changes. This paper explores
the development of relevant climate and non-climate drivers, with an emphasis
on the non-climate drivers. While these issues are applicable within any scenario
framework, our ideas are illustrated using the widely used SRES scenarios, with
both impacts and adaptation being considered. Importantly, scenario
development is a process, and the assumptions that are made about future
conditions concerning the coast need to be explicit, transparent and open to
scientific debate concerning their realism and likelihood. These issues are
generic across other sectors.

alignment evolution of the Iluka-Woody Bay sand barrier, northern New South Wales,
Australia, since 3000 yr BP." Marine Geology 226(1-2): 127-144.
Multi-centennial fluctuations in the northern New South Wales (NSW) coastline
alignment are interpreted from a detailed reconstruction of the morphological and
depositional evolution of the Iluka to Woody Bay barrier during the late Holocene.
The regional coastline is aligned obliquely to the south-east, inner-shelf, modal
wave direction, and hence sediment is transported obliquely on the shoreface
with a net northward movement. On centennial to millennial time scales, the
coastline is shown to have responded to fluctuations in mean wave direction,
longshore gradients in sand transport and headland sand bypassing processes.
Overall, barrier progradation has been punctuated by episodes of shoreline
recession and realignment throughout the late Holocene. A prolonged shoreline
recessional phase occurred at similar to 1500 yr BP in response to a rotation in
modal wave direction from more southerly, towards east-south-easterly.
Subsequent to this realignment, renewed shoreline progradation occurred along
the east aspect coastline after similar to 1400 yr BP whilst the north-east aspect,
coastline remained in a receded alignment until after similar to 1000 yr BP, when
renewed progradation occurred. Progradation rates increased throughout the
past millennium, driven by changes to the alongshore gradient in sand transport,
under an implied shift to a more southerly and energetic modal wave climate. In
the past 50 yrs, the north-east aspect shoreline has experienced a rapid
recessional trend, which is associated with a shift in modal wave climate, to a
more east-southeasterly direction, and a reduction in headland sand bypassing,
The average sand supply rate to the Iluka to Woody Head section of the northern
NSW shoreline is 4.1m(3)/m/yr, since similar to 3000 yr BP. (c) 2005 Elsevier

pageAbstractCausal attribution of recent biological trends to climate change is
complicated because non-climatic influences dominate local, short-term
biological changes. Any underlying signal from climate change is likely to be
revealed by analyses that seek systematic trends across diverse species and
geographic regions; however, debates within the Intergovernmental Panel on
Climate Change (IPCC) reveal several definitions of a ‗systematic trend‘. Here,
we explore these differences, apply diverse analyses to more than 1,700
species, and show that recent biological trends match climate change
predictions. Global meta-analyses documented significant range shifts averaging
6.1 km per decade towards the poles (or metres per decade upward), and
significant mean advancement of spring events by 2.3 days per decade. We
define a diagnostic fingerprint of temporal and spatial ‗sign-switching‘ responses
uniquely predicted by twentieth century climate trends. Among appropriate
long-term/large-scale/multi-species data sets, this diagnostic fingerprint was
found for 279 species. This suite of analyses generates ‗very high confidence‘
(as laid down by the IPCC) that climate change is already affecting living
systems.

Hydrobiologia 595(1): 545-567.
The precise number of extant fish species remains to be determined. About
28,900 species were listed in FishBase in 2005, but some experts feel that the
final total may be considerably higher. Freshwater fishes comprise until now
almost 13,000 species (and 2,513 genera) (including only freshwater and strictly
peripheral species), or about 15,000 if all species occurring from fresh to
brackishwaters are included. Noteworthy is the fact that the estimated 13,000
strictly freshwater fish species live in lakes and rivers that cover only 1% of the
earth’s surface, while the remaining 16,000 species live in salt water
covering a full 70%. While freshwater species belong to some 170 families (or
207 if peripheral species are also considered), the bulk of species occur in a
relatively few groups: the Characiformes, Cypriniformes, Siluriformes, and
Gymnotiformes, the Perciformes (noteably the family Cichlidae), and the
Cyprinodontiformes. Biogeographically the distribution of strictly freshwater
species and genera are, respectively 4,035 species (705 genera) in the
Neotropical region, 2,938 (390 genera) in the Afrotropical, 2,345 (440 genera) in
the Oriental, 1,844 (380 genera) in the Palaearctic, 1,411 (298 genera) in the
Nearctic, and 261 (94 genera) in the Australian. For each continent, the main
characteristics of the ichthyofauna are briefly outlined. At this continental scale,
ichthyologists have also attempted to identify ichthyological
‘‘provinces’’ that are regions with a distinctive evolutionary history
and hence more or less characteristic biota at the species level. Ichthyoregions
are currently identified in each continent, except for Asia. An exceptionally high
faunal diversity occurs in ancient lakes, where one of the most noteworthy
features is the existence of radiations of species that apparently result from
intra-lacustrine speciation. Numerous fish-species flocks have been identified in
various ancient lakes that are exceptional natural sites for the study of speciation.
The major threats to fish biodiversity are intense and have been relatively well
documented: overexploitation, flow modification, destruction of habitats, invasion
by exotic species, pollution including the worldwide phenomena of eutrophication
and sedimentation, all of which are interacting.
Paulson, D. R., J. van Tol, et al. (2008). "Global diversity of dragonflies (Odonata) in
freshwater." Hydrobiologia 595(1): 351-363.
Larvae of almost all of the 5,680 species of the insect order Odonata (dragonflies
and damselflies) are dependent on freshwater habitats. Both larvae and adults
are predators. The order is relatively well studied, and the actual number of
species may be close to 7,000. Many species have small distributional ranges,
and are habitat specialists, including inhabitants of alpine mountain bogs,
seepage areas in tropical rain forests, and waterfalls. They are often successfully
used as indicators for environmental health and conservation management. The
highest diversity is found in flowing waters in rain forests of the tropics, the
Oriental and Neotropical regions being the most speciose. This paper discusses
diversity, summarises the biogeography of dragonflies in the different
biogeographical regions and gives the total number of species and genera per
family per biogeographical region. Examples are given of areas of particular
diversity, in terms of areas of endemism, presence of ancient lineages or
remarkable recent radiations but no well-based review of areas with high
endemism of dragonflies is available so far. The conservation status of
dragonflies is briefly discussed. Species confined to small remnants of forest in
the tropics are most under threat of extinction by human activities.

practices: responses of a soil stored seed bank to logging and repeated prescribed fire."
Austral Ecology: no-no.
Forest management practices have the potential to impact upon native
vegetation. Most studies focus on the effects of management on the
above-ground vegetation communities, with little attention given to the soil stored
seed bank. Here we examine the soil stored seed bank of a long-term
experimental site in south-eastern Australia, which has experienced timber
harvesting and repeated prescribed burning over a 20-year period. At each of
213 long-term vegetation measurement plots, 3.5 kg of soil was collected and
germinated in a glasshouse over a period of 2 years. Comparisons were made
between the experimental treatments considering differences in species
richness, abundance and community composition of the understorey seed bank.
Logged sites had a higher diversity and abundance of seedlings compared with
unlogged sites, which is consistent with observed changes in standing vegetation
within 10 years following logging. Prescribed burning resulted in a lower diversity
and abundance of seedlings, which contrasts with the increase in species
diversity observed in response to frequent fire in standing vegetation. Individual
taxa that declined in the seed bank in response to frequent fire were all taxa for
which germination is enhanced by exposure to smoke. Contrary to expectations,
these did not exhibit a corresponding decline as standing plants. While
management actions above ground are having minor impacts, greater effects
were seen in the soil stored seed bank.

Tropical cyclone-generated wave conditions coincident with extreme phases of

beaches over the period 1972-1989. The study expands upon similar previous
research conducted on Sydney's wave climate. values of summer (Southern
Hemisphere) mean-monthly deepwater wavepower on northern Gold Coast
(Australia) beaches were found to be significantly lower during El Nino Southern
Oscillation (ENSO) phases of the Southern Oscillation than during the opposing
anti-ENSO phases. It is proposed that Southern Oscillation-related variability of
Australian/South-west Pacific tropical cyclone activity is an important mechanism
underlying the observed contrast. A tropical cyclone wave generation area was
constructed for Gold Coast beaches using individual tropical cyclone and site
data Possible coastal management implications of these findings are discussed.

catchment land use on Late Holocene and modern beach-ridge sedimentation on a
tropical macrotidal coast: Keppel Bay, Queensland, Australia." Marine Geology
251(3-4): 195-208.
Beach ridges at Keppel Bay, central Queensland, Australia, preserve a record of
sediment accumulation from the historical period back to middle Holocene times.
The ridges comprise fine, well-sorted, feldspar-rich quartz sand that was eroded
from the Fitzroy River catchment, deposited in Keppel Bay during floods of the
Fitzroy River, and reworked onshore into beach and foredune deposits by the
prevailing currents, waves and wind. These floods have an average recurrence
interval of at least 7 yr and are induced by the passage of cyclones onshore into
the large Fitzroy catchment. The youngest series of beach ridges sit sub-parallel
to the modern beach and comprise six accretional units, each unit formed by a
set of ridges and delineated by prominent swales. Optically stimulated
luminescence (OSL) ages of beach ridges in these units indicate they were
deposited in periods of rapid progradation approximately 1500,1000,450 and 230
yr BP, when there was an enhanced supply of sediment to the beach from the
Fitzroy River via Keppel Bay. Estimates of the mass of sediment stored in the
beach-ridge strandplain show that it represents a significant sediment store,
potentially trapping the equivalent of 79% of the estimated long-term (100 yr)
average annual bedload of the Fitzroy River that is deposited in Keppel Bay.
There has been a reduction in the rate of sediment accumulation in the
strandplain since around 1000 yr BP, which is consistent with other coastal
records in eastern Australia of a relatively wetter phase of climate in the late
Holocene compared to the present. The youngest beach ridges (OSL ages < 100
yr BP) are tall relict foredunes that reflect a low rate of sediment accumulation.
These ridges have a distinctive trace-element composition produced by a greater
contribution from catchment areas with basaltic soils. The change in catchment
provenance has likely been a consequence of erosion that followed clearing of
native vegetation in these areas. Our findings demonstrate the important insights
that beach-ridge deposits proximal to a river sediment source can provide into
processes of sediment accumulation and the response to variations in climate in
tropical coastal sedimentary systems. Crown Copyright (C) 2008 Published by

environmental stressors for encapsulated gastropod embryos on rocky shores?" Marine
Biology 152(4): 991-1002.
Adults of motile intertidal invertebrates are able to seek shelter to avoid
environmental stress associated with low tides, but embryos within egg masses
are effectively sessile for the duration of their encapsulation. Gastropod egg
masses from 34 taxa on two rocky shores in SE Australia (34°37′08″S,
150°92′03″E and 34°35′45″S, 150°53′20″E) were surveyed
over 2 years (June 2002â€―May 2004) to test the hypothesis that eggs are
deposited in patterns that minimize exposure to environmental stress. Egg
masses were expected to be predominantly deposited in shaded habitats not
prone to environmental extremes. It was also anticipated that the deposition of
egg masses in habitats exposed to UVR, desiccation, and/or extremes in
temperature would occur when exposure to these abiotic factors was minimized.
Among the taxa investigated, only four species spawned in full sun (Bembicium
nanum, Nerita morio, Siphonaria zelandica and S. denticulata). Summer had the
highest UVR index, water temperature, and air temperature as well as the lowest
daytime tides. Univariate and multivariate analyses confirmed that egg mass
abundance was highest during summer, with no change in egg mass size. This
study shows that those species depositing egg masses on the surfaces of rock
platforms do not adjust the seasonal timing or macrohabitat location of their
spawning to avoid physiologically stressful conditions, particularly UVR. Alternate
reasons for the evolution of egg mass deposition behavior in apparently
sub-optimal habitats are discussed, and it is almost certainly the complex
interplay of a variety of highly species-specific factors that is responsible for the
patterns observed.
Ranasinghe, R. (2004). "The Southern Oscillation Index, wave climate, and beach
rotation." Marine Geology 204(3-4): 273-287.
Short embayed beaches bounded by headlands are a common feature along the
southern and central coastline of New South Wales, Australia. Many of these
embayed beaches have experienced severe erosion at their southern end over
the last decade. Previous studies have suggested that this erosion may be the
result of an oscillatory medium-term phenomenon known as beach rotation. The
present study was undertaken with the objectives of: (1) establishing definitive
links between the Southern Oscillation Index (Sol), wave climate, and beach
rotation, and (2) determining the physical processes governing beach rotation.
Data from two similar New South Wales beaches were analysed using time
series analysis techniques and image processing techniques (using ARGUS
video images) in this study. The results indicate that the northern end of this type
of beach accretes during El Nino phases, while the southern end erodes,
resulting in a net clockwise rotation of the beach. The opposite occurs during La
Nina phases resulting in a net anti-clockwise rotation of the beach. The beach
response at the northern and southern ends lags Sol trend shifts by 3 and 17
months, respectively. Waves are predominantly incident from the southeast
during both El Nino and La Nina phases. Offshore wave height is positively
correlated with the Sol while offshore wave direction is negatively correlated with
the Sol. On average, the number of storms per year doubles from El Nino to La
Nina. Based on these links between beach width fluctuations, SOI, and incident
wave conditions, a conceptual model of beach rotation is presented. The model
describes the combinations of cross-shore and longshore sediment transport and
hydrodynamic processes that are expected to result in the observed clockwise
and anti-clockwise beach rotation during El Nino and La Nina phases,
respectively. Crown Copyright (C) 2004 Elsevier B.V. All rights reserved.
Ranasinghe, R., A. Short, et al. (2008). "Statistical simulation of wave climate and
extreme beach erosion." Coastal Engineering 55(5): 375-390.
Recent developments in extreme values modelling have been used to develop a
framework for determining the coastal erosion hazard on sandy coastlines. This
framework quantitatively reproduced the extreme beach erosion volumes
obtained from field measurements at Narrabeen Beach, Australia. This
encouraging finding was achieved using Kriebel and Dean's [Kriebel, D.L. and
Dean, R.G., 1993. Convolution method for time-dependent beach profile
response. Journal of Waterway, Port, Coastal and Ocean Engineering, 119(2):
204-226.] simple beach erosion and accretion model. The method includes
allowances for joint probability between all basic erosion variates including; wave
height, period and direction, event duration, tidal anomalies and event spacing. A
new formulation for the dependency between wave height and period has been
developed. It includes the physical wave steepness limitation. Event grouping,
where significantly more erosion can occur from two closely spaced storms is
handled by temporally simulating the synthetic wave climate and the resulting
beach erosion and accretion. (C) 2007 Elsevier B.V. All rights reserved.

The path of environmental law has come to a cliff called climate change, and
there is no turning around As climate change pokey dialogue emerged in the
1990s, however, the perceived urgency of attention to mitigation strategies
designed to regulate sources of greenhouse gas emissions quickly snuffed out
meaningful progress on the formulation of adaptation strategies designed to
respond to the effects of climate change on humans and the environment. Only
recently has tiffs "adaptation deficit" become a concern now actively included in
climate change pokey debate. Previously treating talk of adaptation as taboo, the
climate change pokey world has begrudgingly accepted it into the fold as the
reality of failed efforts to achieve global mitigation policy has combined with the
scientific evidence that committed warming will continue the trend of climate
change well into the future regardless of mitigation policy success.

from long-term flowering records of plants along the Victorian coast, Australia."
Australian Journal of Botany 58(6): 428-439.
We investigate the utility of using historical data sources to track changes in
flowering time of coastal species in south-eastern Australia in response to recent
climate warming. Studies of this nature in the southern hemisphere are rare,
mainly because of a paucity of long-term data sources. Despite this, we found
there is considerable potential to utilise existing data sourced from herbaria
collections and field naturalists’ notes and diaries to identify native plant
species suitable as biological indicators of climate change. Of 101 candidate
species investigated in the present study, eight were identified as showing a
general trend towards earlier flowering over time, indicating a correlation with
increasing temperatures. There was some evidence to suggest that species
which flower in spring and summer may be more sensitive to changes in
temperature. There was a high level of uncertainty regarding the detection of
trends, which was a function of the accessibility, abundance and accuracy of the
various data sources. However, this uncertainty could be resolved in future
studies by combining the datasets from the present study with field monitoring of
phenological cycles in climatically different locations. Data held by community
groups could be made more accessible if there was a concerted effort to fund
collation and digitisation of these records. This might best be achieved by
working with community groups, and facilitated through the recent establishment
of a community phenological observation database in Australia.

One of the things with climate change that the author finds particularly unnerving
is that the weather is supposed to change. Change means more dramatic swings
in temperature and, very importantly, precipitation. Availability of water to drink
and more importantly for people to grow their food is likely to be the first major
impact of climate change. Agriculture has tools like drip irrigation systems instead
of flood or overhead spray systems, which can make a huge difference. But
another thing that people can do is use more compost. Steps are: 1. Get water
into the soil. 2. Keep it there.

The increasing awareness of the effects of climate change on plant distributions
in situ has made the appropriate application of ex situ techniques more crucial.
These ex situ conservation techniques need to be targeted to priority species
identified at risk from climate change. The present paper assesses the sensitivity
of plant species to climate change in Belgium and explores the current
conservation status of those species potentially vulnerable to climate change. We
then checked whether these species were included in ex situ collections. The
whole Belgian flora has been assessed (a total of 1,396 native plant species).
We evaluated whether each of these species occurs in a "climate
change-vulnerable" habitat, having therefore a higher probability to be impacted
by climate change. The assessment revealed that there are at least 415 native
plant species (30% of the Belgian native flora) that appear to be vulnerable to
climate change during the next decades. Results also showed that about
one-third of the species currently included in the red list may have their situation
made potentially worse due to climate change. In addition, depending on the
region, between 45 and 67% of the species that are currently not threatened in
Belgium are likely to become so due to climate change. It also appeared that only
32% of these climate change-vulnerable species are currently held ex situ. We
conclude that there is a need to identify gaps in existing ex situ collections as an
urgent priority and ensure that species potentially vulnerable to climate change
are conserved ex situ.[PUBLICATION ABSTRACT]

Escalating pressures caused by the combined effects of population growth,
demographic shifts, economic development and global climate change pose
unprecedented threats to sandy beach ecosystems worldwide. Conservation of
beaches as functional ecosystems and protection of their unique biodiversity
requires management interventions that not only mitigate threats to physical
properties of sandy shores, but also include ecological dimensions. Yet, beach
management remains overwhelmingly focused on engineering interventions.
Here we summarise the key outcomes of several workshops, held during the
2006 Sandy Beach Ecology Symposium in Vigo, Spain, that addressed issues of
climate change, beach management and sampling methodology. Because
efficient communication between managers and ecologists is critical, we
summarise the salient features of sandy beaches as functional ecosystems in 50
'key statements'; these provide a succinct synopsis of the main structural and
functional characteristics of these highly dynamic systems. Key outcomes of the
workshops include a set of recommendations on designs and methods for
sampling the benthic infaunal communities of beaches, the identification of the
main ecological effects caused by direct and indirect human interventions, the
predicted consequence of climate change for beach ecosystems, and priority
areas for future research.

terrestrial-aquatic energetic connectivity in intermittently connected estuaries of tropical
Australia." Marine Biology 157(9): 2071 - 2086.
δ^sup 13^C was used to identify seasonal variations in the importance of
autochthonous and allochthonous sources of productivity for fish communities in
intermittently connected estuarine areas of Australia's dry tropics. A total of 224
fish from 38 species were collected from six intermittently connected estuarine
pools, three in central Queensland (two dominated by C3 forest and one by
C^sub 4^ pasture) and three in north Queensland (one dominated by C^sub 3^
and two by C^sub 4^ vegetation). Samples were collected before and after the
wet season. Fish collected in the two forested areas in central Queensland had
the lowest δ^sup 13^C, suggesting a greater incorporation of C^sub 3^ terrestrial
material. A seasonal variation in δ^sup 13^C was also detected for these areas,
with mean δ^sup 13^C varying from -20 to -23% from the pre- to the post-wet
season, indicating a greater incorporation of terrestrial carbon after the wet
season. Negative seasonal shifts in fish δ^sup 13^C were also present at the
pasture site, suggesting a greater dependence on carbon of riparian vegetation
(C^sub 3^ Juncus sp.) in the post-wet season. In north Queensland, terrestrial
carbon seemed to be incorporated by fish in the two C^sub 4^ areas, as δ^sup
13^C of most species shifted towards slightly heavier values in the post-wet
season. A two-source, one-isotope mixing model also indicated a greater
incorporation of carbon of terrestrial origin in the post-wet season. However, no
seasonal differences in δ^sup 13^C were detected for fish from the forested area
of north Queensland. Overall, hydrologic connectivity seemed to be a key factor
in regulating the ultimate sources of carbon in these areas. It is therefore
important to preserve the surrounding habitats and to maintain the hydrologic
regimes as close to natural conditions as possible, for the conservation of the
ecological functioning of these areas. [PUBLICATION ABSTRACT]

shifts: Where and how should we be looking?" Austral Ecology 31(1): 22-29.
Global climate warming is expected to cause systematic shifts in the distribution
of species and consequently increase extinction risk. Conservation managers
must be able to detect, measure and accurately predict range shifts in order to
mitigate impacts on biodiversity. However, important responses to climate
change may go unnoticed or be dismissed if we fail to collect sufficient baseline
data and apply the most sensitive analytical tests. Here we use randomizations
of a contemporary data set on rainforest birds of north-eastern Australia to
quantify the sensitivity of three measures for assessing range shifts along
altitudinal gradients. We find that smaller range shifts are detectable by analysing
change in the mean altitude of presence records rather than upper or lower
range boundaries. For a moderate survey effort of 96 surveys, measurements of
change in the mean altitude of 34 species have the capacity to provide strong
inference for a mean altitudinal range shift as small as 40 m across the species
assemblage. We also show that range shifts measured at range boundaries can
be potentially misleading when differences in sampling effort between
contemporary and historical data sets are not taken into account.

Swan Coastal Plain (Western Australia) wetlands affected by drought-induced
acidification." Hydrobiologia 624(1): 191-203.
Management of wetlands influenced by the Gnangara groundwater mound,
Western Australia, is becoming increasingly challenging due to an ongoing
decline in the regional groundwater table. A number of these
groundwater-dependent wetlands have acidified (with adverse effects on the
extant macroinvertebrate fauna) due to the oxidation of pyritic sediments. One
management option in such cases is artificial augmentation of surface water in
order to maintain or reinstate anaerobia in the sediments. This paper documents
cycles of macroinvertebrate decline and recovery over 12 years of monitoring in
three Gnangara mound wetlands affected by drought-induced acidification, one
of which is being artificially augmented. Acidification did not result in a reduction
of the total number of macroinvertebrate families present, however, there were
clearly identifiable groups of acid-sensitive taxa (amphipods and isopods,
ostracods, chydorid and daphnid cladocerans, mayflies, oligochaetes, clams and
snails) and acid-tolerant taxa (sandfly larvae, macrothricid cladocerans and water
boatmen). In the artificially augmented wetland, the effects of acidification were
reversed: acid-sensitive taxa reappeared and acid-tolerant taxa decreased in
numbers. Moreover, there were a number of taxa that appeared for the first time
since augmentation, and summer family richness increased markedly. This study
has shown that artificial augmentation of wetland water levels can be a
successful recovery strategy for recently acidified systems, but this will depend
on a number of factors, and the ‘recovered’ state will be at least slightly
different from the original state.
Spencer, R.-J. and G. S. Baxter (2006). "Effects of fire on the structure and composition
of open eucalypt forests." Austral Ecology 31(5): 638-646.
Fires are integral to the healthy functioning of most ecosystems and are often
poorly understood in policy and management, however, the relationship between
floristic composition and habitat structure is intrinsically linked, particularly after
fire. The aim of this study was to test whether the variability of habitat structure or
floristic composition and abundance in forests at a regional scale can be
explained in terms of fire frequency using historical data and experimental
prescribed burns. We tested this hypothesis in open eucalypt forests of Fraser
Island off the east coast of Australia. Fraser Island dunes show progressive
stages in plant succession as access to nutrients decreases across the Island.
We found that fire frequency was not a good predictor of floristic composition or
abundance across dune systems; rather, its affects were dune specific. In
contrast, habitat structure was strongly influenced by fire frequency, independent
of dune system. A dense understorey occurred in frequently burnt areas,
whereas infrequently burnt areas had a more even distribution of plant heights.
Plant communities returned to pre-burn levels of composition and abundances
within 6 months of a fire and frequently burnt areas were dominated by early
successional species of plant. These ecosystems were characterized by low
diversity and frequently burnt areas on the east coast were dominated by
Pteridium. Greater midstorey canopy cover in low frequency areas reduces light
penetration and allows other species to compete more effectively with Pteridium.
Our results strongly indicate that frequent fires on the Island have resulted in a
decrease in relative diversity through dominance of several species. Prescribed
fire represents a powerful management tool to shape habitat structure and
complexity of Fraser Island forests.

Physical Geography 24(3): 311-327.
This review identifies four themes in shore platform research: 1) the role of
marine and subaerial processes in platform development; 2) morphology of shore
platforms; 3) modelling platform development; and 4) measuring rates of erosion.
The view that shore platforms have a wave-cut origin has dominated the
literature in the last 20 years. It is argued that this wave-cut origin remains to be
convincingly demonstrated. Attempts to link platform morphology with the
process environment have proven difficult but a recent demarcation between
platform morphologies based on wave erosion and rock resistance offers an
interesting and new way to consider platform morphology. Attempts to model
platform development have been handicapped by a lack of data and a clear
understanding of development processes. All models are based on the premise
that platforms have a wave-cut origin, yet this has not been adequately
demonstrated. There are a number of contradictions between models that require
resolution. Erosion rates have been measured using the micro-erosion meter, but
these studies are restricted both temporally and spatially. The contribution of
microscale erosion relative to other forms and scales remains unknown. A
number of issues are raised and suggested as being suitable questions for future
research. It is proposed that real advances in understanding shore platforms will
be aided by collaborative work between researchers from a number of
morphogenetic environments.

by mangroves and saltflats." Estuarine Coastal and Shelf Science 54(6): 1039-1049.
Mangrove swamps and hypersaline saltflats fringe many estuaries in dry tropical
climates, especially in Northern Australia. For most of the year these estuaries
receive zero riverine freshwater input and thus, after the wet season, a steady
increase in salinity occurs. In some locations the estuary becomes fully inverse,
i.e. the salinity increases monotonically from the mouth to the head. In other
locations, a salinity maximum zone separates the sea from low salinity water that
persists at the head of the estuary throughout the dry season. Field data from
five estuaries indicate that in short estuaries where a large area of saltflats and
mangroves extends over the whole length of the estuary, the estuary becomes
completely inverse with salinity rising to 55 within a couple of months. The
evaporation and evapotranspiration over the saltflats and mangroves cause this
rapid increase in salinity. Longer estuaries where a large area of salt flat exists
only close to the mouth do not become completely hypersaline for the whole
length of the estuary by the end of the dry season. A salinity-maximum is
generated close to the river mouth but salinities of less than 10 persist in the
upper reaches of the estuary until the end of the dry season, even though the
estuary does not receive any further freshwater input. A simple analytical
expression is presented that reproduces the changes in salinities in the estuaries
studied. This model can be used to predict the formation of hypersaline
conditions in other mangrove and saltflat fringed estuaries where freshwater flow

Abstract There is less certainty about the impact of climate change on tropical
rainforests than on temperate forests because of the comparative lack of
background data and because few large scale experiments have been, and are
being, carried out in tropical rainforests. Many of the factors critical to the future
of tropical rainforests concern canopies, the key processes that take place there,
and the roles and interactions of canopy biodiversity. In particular there are
almost no data on how forest canopies and processes are changing with
increased carbon dioxide levels. The implications of elevated carbon dioxide,
climatic stress and related changes in water-use efficiency, nutrient availability
and other such changes are discussed particularly with references to Australia's
tropical rainforests.

South Australia." The Holocene 11(3): 281-290.
Wetland degradation in the Upper South East of South Australia is an urgent
management concern. Scant recent environmental data is available for the
region and long-term monitoring data is lacking. Usually a palaeoecological
analysis is able to reveal environmental change in the medium- to long-term past.
However, the region is not conducive to palaeoecological investigation due to a
fluctuating upper groundwater aquifer and alkaline soils which have destroyed
most microfossils. It was found that the diatom assemblage was preserved in the
wetlands of the region for the period of European settlement. Analysis of the
diatom assemblage enabled production of an inferred salinity curve. In
combination with a small amount of historical information that was available, the
salinity trend for the wetlands, for the period of European agricultural activities,
was identified. It was found that, while groundwater salinity has been increasing,
the wetland areas have experienced a freshening of surface water. This is due to
an increase of throughflow of surface water, a result of constructed drainage
systems flushing salts from the wetlands. Despite the freshening of wetlands they
continue to degrade due to the changed hydrology, an impact of the drainage
structures.

impact from a coastal environment: Tuckean Swamp, eastern Australia." Journal of
Paleolimnology 39(1): 71-82.
Diatom-based paleolimnological studies are being increasingly used to track
anthropogenic change in estuaries. Little is known, however, about the direction
and nature of long-term environmental changes in Australian estuaries. In this
study, shifts in diatom assemblages preserved in a 210Pb and C14 AMS dated
sediment core from Tuckean Swamp were analysed to determine environmental
changes that had taken place as a result of changing land-use practices. Prior to
European impact, the diatom assemblage remained relatively stable and was
dominated by Actinocyclus normanii and Diploneis smithii. An increasing
dominance of Cyclotella meneghiniana correlates well with changed land use
activities in the catchment area and indicates an increase of freshwater influence
in the swamp’s environment. A major shift in species composition began
∼1970, Eunotia flexuosa becoming dominant. The assemblage shifts recorded
at this site appear to be consistent with environmental changes triggered by
human activities such as vegetation clearance, drainage and the construction of
a barrage. This study demonstrates the use of paleolimnoology in an estuarine
environment to provide pre-impact data necessary for management of the
aquatic environment.

Journal of Coastal Management 35(4): 499 - 509.
The mobile nature of soft coasts means that coastal communities face
uncertainty in their property values and peace of mind when the existing coastal
defense is lowered or removed. The acceptance by the U.K. government that
coastal realignment in areas of low population density and limited ecological
value is unavoidable means that the current state of affairs, where coastal
residents have broadly come to assume that they will be defended if they make
enough fuss, cannot continue. The government is currently unwilling to confront
this consternation and continues to refuse to pay compensation for lost property
value. This is creating an outcry over loss of fairness of treatment. This dispute
raises important questions of governance for coastal change. This participatory
research project worked closely with English Nature, North Norfolk District
Council, local residents associations, the Environment Agency, and the
Department for Environment, Food and Rural Affairs. What emerged in the
analysis were unresolved tensions between national strategic frameworks,
emerging planning arrangements, changing economic assessments, and the
desirability of delivering, through a number of public and voluntary agencies,
local flexibility in participation and in coastal design. This article reports on the
research process, the challenges for coastal governance, and the scope for
creative partnerships between science, planning, policy delivery, and public
acceptance.

and ecological impacts caused by vehicle tracks associated with beach camping on
sandy shores: a case study from Fraser Island, Australia." Journal of Coastal
Conservation 12(2): 67-82.
As coastal populations expand, demands for recreational opportunities on
beaches and coastal dunes grow correspondingly. Although dunes are known to
be sensitive to direct human disturbance and provide irreplaceable ecosystem
services (e.g. erosion control, critical habitat and nesting sites), dunes serve as
campsites for large numbers of people (∼90,000 p.a.) on the ocean-exposed
shores of Fraser Island, Australia. Campsites are located in the established
dunes and can only be accessed with 4WD vehicles along tracks cut directly
from the beach through the foredunes. Here we quantified the extent of physical
damage to foredunes caused by this practice, and tested whether
human-induced physical changes to foredunes translate into biological effects. Of
the 124 km of ocean-exposed beaches, 122 km (98%) are open to vehicles
driven on the beaches, and camping zones cover 28.7 km or 23% of the dunes.
A total of 235 vehicle tracks are cut across the foredunes at an average density
of eight tracks per km of beach. These tracks have effectively destroyed one-fifth
(20.2%) of the dune front in camping zones, deeply incising the dune-beach
interface. There is evidence of accelerated erosion and shoreline retreat centred
around vehicle tracks, resulting in a “scalloping― of the shoreline. No dune
vegetation remains in the tracks and the abundance of ghost crabs (Ocypode
spp.) is significantly reduced compared with the abutting dunes. Because current
levels of environmental change caused by dune camping may not be compatible
with the sustainable use of coastal resources and conservation obligations for the
island (listed as a World Heritage Area and gazetted as a National Park),
restoration and mitigation interventions are critical. These will require spatial
prioritisation of effort, and we present a multi-criteria ranking method, based on
quantitative measures of environmental damage and ecological attributes, to
objectively target rehabilitation and conservation measures. Ultimately, coastal
management needs to develop and implement strategies that reconcile demands
for human recreation, including beach camping, with conservation of coastal
dune ecosystems.

biodiversity changes for ecosystem functioning of North European rocky shores."
Marine Ecology Progress-Series
396: 245-259.
We review how intertidal biodiversity is responding to globally driven climate
change, focusing on long-term data from rocky shores in the British Isles.
Physical evidence of warming around the British Isles is presented and, whilst
there has been considerable fluctuation, sea surface temperatures are at the
highest levels recorded, surpassing previous warm periods (i.e. late 1950s).
Examples are given of species that have been advancing or retreating polewards
over the last 50 to 100 yr. On rocky shores, the extent of poleward movement is
idiosyncratic and dependent upon life history characteristics, dispersal
capabilities and habitat requirements. More Southern, warm water species have
been recorded advancing than northern, cold water species retreating. Models
have been developed to predict likely assemblage composition based on future
environmental scenarios. We present qualitative and quantitative forecasts to
explore the functional consequences of changes in the identity, abundance and
species richness of gastropod grazers and foundation species such as barnacles
and canopy-forming algae. We forecast. that the balance of primary producers
and secondary consumers is likely to change along wave exposure gradients
matching changes Occurring with latitude, thereby shifting the balance between
export and import of primary production. Increases in grazer and sessile
invertebrate diversity are likely to be accompanied by decreasing primary
production by large canopy-forming fucoids. The reasons for Such changes are
discussed in the context of emerging theory on the relationship between
biodiversity and ecosystem functioning.

case study from Cockburn Sound, southwestern Australia." Journal of Coastal
Research 23(2): 429-444.
Low-energy beaches are omnipresent coastal features. In total, their overall
length greatly exceeds that of ocean shorelines throughout the world. However, a
comprehensive understanding of low-energy beaches is lacking, with their
dynamics generally considered under existing principles governing open ocean
beaches. This study investigates the morphodynamic characteristics of very low
energy beaches on which wave heights can be less than 0.15 m under nonstorm
conditions, as distinguished from the characteristic of high-energy environments
in which low energy states commonly have modal wave heights of 0.5-1 m. This
investigation is achieved through an analysis of a 30-year profile data set for
Cockburn Sound, a fetch-limited, low-energy basin in southwestern Australia.
The Sound experiences the full ranging of microtides and surges of the region,
together with locally generated wind waves. Recurring patterns in cross-shore
geometries and their distribution were identified through regression analysis of
mean profile shapes. The spatial variability in the wind-wave regime was
established by hindcasting conditions for key fetch directions. Cluster analysis of
profile and environmental variables identified four morphotypes. Each
morphotype can be explained in terms of a simple exposure factor, Ef =
log(Fl/Ms), which is the proportion of fetch length (Fl) to marginal shoal width
(Ms), such that Ef < 1 was characteristic of exponential profiles, Ef = 1-1.5 of
segmented profiles, Ef = 1.5-2 of concave-curvilinear profiles, and Ef > 2 of
convex-curvilinear profiles. Thus, the exposure factor is identified as a useful
nondimensional parameter for the delineation of low-energy profile morphotypes
within the study area. The utility of this approach in widespread classifications of
low-energy beach morphology requires further research. This should take place
in a variety of environments with varying degrees of protection and shelter from
swell and subject to different tidal ranges and fluctuations in sea level.
Trenhaile, A. (2002). "Rock coasts, with particular emphasis on shore platforms."
Geomorphology 48(1-3): 7-22.
Rock coasts are one of the most common elements of the world's littoral zone,
and they are often important sources of sediment for estuaries and beaches.
Economic development, growing populations, and the potential effects of rising
sea level provide a practical need to understand the dynamics of these coasts.
Although there have been significant advances in our understanding of rocky
coastal systems, further progress has been hindered by a lack of researchers
and by the often imperceptible changes that generally occur within human time
scales. This paper reviews rock coast processes and landforms in a variety of
morphogenic environments. One of our most fundamental challenges is to
determine the degree to which rock coasts are contemporary rather than
inherited features from the Quaternary, when changes in sea level and climate
were responsible for marked variations in the nature, intensity, and elevational
distribution of the marine and subaerial processes that sculpture rock coasts. (C)

Marine Ecology - Pubblicazioni Della Stazione Zoologica Di Napoli 15(3-4): 177-211.
The interstitial system of sandy beaches is lacunar and has its dimensions
defined by the sand granulometry. It can be described by features such as pore
size, porosity, permeability, and water content. The most important process
occurring in this system, water filtration, is driven by inputs of freshwater from
groundwater discharge, and inputs of seawater by tides, wave run-up, and
subtidal wave pumping. Reflective beaches have seawater input effected mainly
by waves; they filter large water volumes with short residence times. Dissipative
beaches display the opposite patterns, slowly filtering small volumes input by
tides. Flow patterns and their effects on interstitial climate are described. The
water table of the beach moves in response to groundwater discharge, tides, and
waves and influences erosion/accretion processes on the beach face: a high
water table promotes erosion. A series of moisture zones can be recognised from
the dry surface sand at upper tide levels, to permanently saturated sand below
the low tide water table, namely: a stratum of dry sand, a stratum of retention, a
stratum of resurgence, and stratum of saturation. Interstitial chemistry is briefly
described in terms of salinity changes, organic loads, oxygen content, and
nutrient cycling. It is concluded that the interstitial environment of sandy beaches
spans a continuum between physically and chemically controlled extremes: the
former condition occurs on coarse sand reflective beaches, which experience low
organic inputs and high filtration rates of large water volumes - resulting in
powerful hydrodynamic forces; the latter occurs on dissipative beaches of fine
sand, which are subject to high organic inputs and low filtration volumes -
resulting in stagnation and steep vertical chemical gradients. Many intermediate
situations occur and these are more favourable to interstitial life than either of the
extremes.

Australians are known for their fierce independence, and now they're increasingly
moving to take climate change matters into their own hands. It's not a moment
too soon, given that the country is experiencing what scientists call "accelerated
climate change" thanks to its dry climate. Two new proposed pieces of legislation
would allow many Aussies to help defend themselves from the effects of climate
change, but critics are worried that they may also adversely affect the
environment.
In New South Wales, state legislators are moving to override local planning policies that
prohibit coastal fortification to let beachside residents protect their homes against
rising tides believed to be caused by climate change. The NSW government said
it would list 19 "hot spot" beaches where waterfront homes were at risk from
rising sea levels. Property owners in those areas would be given more rights to
construct sea walls and barriers, with the state government appointing itself as
final judge over any barrier plans rejected by local councils. Homeowners are
pleased with the plan, but environmentalists fear widespread coastal defenses
could block the movement of sand, causing massive erosion.
Meanwhile, a new program launched in the state of Queensland will help motorists
offset their carbon emissions. Through the "Reverse the Effect" program,
Queensland residents will receive a flyer with their car registration renewal
notices announcing that they can pay an additional fee with the registration to
help offset the emissions created by their automobiles. The state government
has allocated $4.5 million over the next five years to match motorists'
contributions dollar for dollar.
The goal of the program is to offset 290,000 tons of C[O.sub.2]. But carbon offset
programs have come under fire for encouraging a sort of pay-to-pollute mentality
and for not translating directly to emissions reductions.

on an Estuarine Beach." Journal of Coastal Research
1: 153-157.
Sandwave formation at the shoreline has been related to waves with a high
incidence angle. This paper presents the evolution and longshore movement of a
shoreline-attached sandwave on the northern shoreline of Port Stephens estuary
(NSW, Australia) from 1968 to present. Results presented include historic
evolution using Geographic Information Systems (GIS) and periodic topographic
measurements to evaluate shorter term evolution and wave climate. Port
Stephens is a tide-dominated estuary located on a wave-dominated coast; it is a
drowned river valley estuary with a large shallow flood tide delta that provides
some protection to the estuarine beaches. The orientation of the estuary mouth
(SE) coincides with the dominant wave energy permitting propagation of
southerly waves inside the estuary. The north shore of the lower estuary
comprises a shoreline that alternates areas characterised by overall erosion and
accretion, terminating at a sand spit that is extending westwards; the sandwave
forms and develops near the estuary mouth. Decadal studies of the sandwave
show that the first observed sandwave occurred in the 1980s, that was followed
by a period of intense accretion until 2001 and since then sandwave migration
has slowed down. Short term evolution indicates that the sandwave is a highly
dynamic area with a net gain of sediments between March 2007 and April 2008
of +10 x 10(3) m(3). During the study period some high energy storms occurred
during which it was observed that while the sandwave was accumulating
sediment, erosion was occurring on other parts of the beach. The sandwave has
recently been dredged for nourishment purposes and ongoing work is measuring
sandwave recovering after the dredging.

Coastal geomorphologists are becoming increasingly concerned with applied
studies for a variety of reasons, including economic considerations. However,
there are other remaining challenges for coastal geomorphologists including
relating processes and forms, observa tions and theories to produce convincing
and useful explanatory frameworks. Without these developments, applied studies
will always lack rigour and predictive power. In the following sections I review
some recent observational, theoretical and applied work in coastal
geomorphology in general and then focus on coastal sand dune studies.

an eroding coastal region over the twenty-first century." Climatic Change 84(2):
141-166.
A numerical model detailing the functioning and emergent behaviour of an
eroding coastal system is described. Model output from a 50-km study region
centred on the soft-rock shore of northeast Norfolk was verified through
comparison with cliff recession rates that were extracted from historical maps
spanning more than a century. Predictions were then made for the period 2000 to
2100 under combined climatic change and management scenarios. For the
scenarios evaluated, the model was relatively insensitive to increases in offshore
wave height and moderately sensitive to changes in wave direction, but the most
important effects were associated with accelerated sea-level rise (SLR). In
contrast to predictions made using a modified version of the Bruun rule, the
systems model predicted rather complex responses to SLR. For instance, on
some sectors of coast, whereas the Bruun rule predicted increased recession
under accelerated SLR, the systems model actually predicted progradation owing
to the delivery of sediment from eroding coasts up-drift. By contrast, on coasts
where beaches are underlain by shore platforms, both the Bruun rule and the
systems model predicted accelerated recession rates. However, explicit
consideration of the interaction between beach and shore platform within the
systems model indicates that these coasts have a broader range of responses
and lower overall vulnerability to SLR than predicted by the Bruun rule.

and wetland management in the Australian wet-dry tropics." Wetlands Ecology and

The vulnerability of coastal areas in the Alligator Rivers Region (northern
Australia) to predicted climate change and potential sea level rise was assessed
as part of a national study. The coastal area is composed of a number of
estuarine and freshwater habitats that are intricately interlinked and can not be
effectively managed in isolation of each other. The outcomes of the assessment
focused on the floodplain environments of the region, but are also applicable to
the broader wetland environments that occur across the northern Australian
wet-dry tropics. The management regime in the region is based on traditional
Aboriginal ownership of much of the land, which is leased to the federal
government as a national park. Scientific research has been intensive; however,
important questions have been raised about the collation and effective use of this
information. The vulnerability assessment framework required effective use of
this information and cooperation with the management authority to identify
change scenarios and management and research responses. A climate change
scenario was established as the basis for predicting biophysical change in the
coastal and wetland environments. The predictions suggest that large-scale
change will occur and many of the existing values derived from these areas (i.e.,
usage by traditional Aboriginal occupants, and nature conservation) could be
degraded or even lost. Recommended management responses include the
initiation of specific monitoring, empowerment of local bodies to take active
management steps, and to increase awareness of the likely consequences of
change. Further data coordination and review are needed to ascertain the validity
of the predictions and the concomitant management responses.

Myall Lakes is a large brackish coastal lake on the east coast of Australia that
was considered pristine until the occurrence of blue-green algal blooms in 1999.
The temporal and spatial extent of chemical and biological changes to the water
column of Myall Lakes was studied intensively after a rain event in 2002. Water
quality profiles (T, EC, pH, DO), turbidity (secchi), nutrients (TN, NO x , NH4 +,
DON, TP, FRP, DOP, Si), and phytoplankton (chl a and cell counts) were
measured at nine sites on eight occasions immediately after the rain event.
Freshwater inflows affected a large area of the lake. Greatest changes were
seen in areas close to the mouth of the upper Myall River which is the largest
freshwater input to the lakes. Here, greatly elevated concentrations of NO x , TP,
and FRP (up to two orders of magnitude higher than background) were recorded
immediately after the rain event but persisted for only 2 to 8Â days. Slightly
elevated concentrations of TP and NO x were seen in inflows from the smaller
Boolambayte Creek. Stratification was associated with bottom water anoxia and
release of ammonia from the sediments. Identification of the sources of nutrient
species delivered from different parts of the catchment, combined with studies of
nutrient loads can assist managers to develop effective nutrient reduction
strategies to reduce the incidence of blue-green algal blooms in Myall Lakes.

wetlands; W.J. Junk; Future of tropical wetlands." Environmental Conservation 29(4):

Tropical wetlands assume important functions in the landscape and contribute
considerably to the welfare of large parts of the human population, but they are
seriously threatened because they are considered free resources of land and
water. This review summarizes long-term environmental trends for tropical
wetlands and predicts their future to the time horizon 2025. Many tropical
countries do not have the economic strength, scientific and technological
capacity, and/or administrative infrastructure to adequately react to the
challenges of increasing population pressure and globalization of the economy
with respect to the sustainable use of the resources. Furthermore, political
instability and armed conflicts affect large areas in several tropical countries,
hindering wetland research and management. Detailed wetland inventories are
missing in most countries, as are plans for a sustainable management of
wetlands in the context of a long-term integrated watershed management.
Despite large regional variability, a continental ranking shows, in decreasing
order of wetland integrity, South America, Africa, Australia and Asia, while efforts
to mitigate human impacts on wetlands are largest and most advanced in
Australia. Analysis of demographic, political, economic and ecological trends
indicates fairly stable conditions for wetlands in tropical Australia, slight
deterioration of the large wetland areas in tropical South America excepting the
Magdalena and Cauca River flood plains where human population is larger,
rapidly increasing pressure and destruction on many African and Central
American wetlands and serious threats for the remaining wetlands in tropical
Asia, by the year of 2025. Policy deficiencies, deficient planning concepts, limited
information and awareness and institutional weakness are the main
administrative reasons for wetland degradation and must be overcome to
improve wetland management and protection in future. Intensification of
international cooperation and assistance is considered of fundamental
importance for most tropical countries to solve problems related to wetland
research, protection and sustainable management. [PUBLICATION ABSTRACT]

The coastal zone is where land, ocean, and atmosphere interact. It exhibits a
wide diversity of geomorphological types and ecosystems, each one displaying
great variability in terms of physical and biogeochemical forcings. Despite its
relatively modest surface area, the coastal zone plays a considerable role in the
biogeochemical cycles because it receives massive inputs of terrestrial organic
matter and nutrients, is among the most geochemically and biologically active
areas of the biosphere, and exchanges large amounts of matter and energy with
the open ocean. Coastal ecosystems have therefore attracted much attention
recently and are the focus of several current national and international research
programs (e.g. LOICZ, ELOISE). The primary production, respiration,
calcification, carbon burial and exchange with adjacent systems, including the
atmosphere, are reviewed for the major coastal ecosystems (estuaries,
macrophyte communities, mangroves, coral reefs, and the remaining continental
shelf). All ecosystems examined, except estuaries, are net autotrophic. The
contribution of the coastal zone to the global carbon cycle both during pristine
times and at present is difficult to assess due to the limited metabolic data
available as well as because of major uncertainties concerning the magnitude of
processes such as respiration, exchanges at the open ocean boundary, and
air-sea fluxes of biogases.

Singapore Journal of Tropical Geography 24(1): 111-132.
From a physical geography perspective, tropical coasts are characterised by
coral reefs, mangroves and carbonate beaches on atolls and low reef islands.
They face threats not only from sea level rise, but also from human activities that
destroy mangroves, degrade coral reefs and accelerate beach erosion. Physical
conditions in the tropics are suitable for the ideal tourist beach. Conceptually, the
tourist coast can be considered as the integration of a physical system (the
coast) and a human system (tourism). Studies have been carried out on various
types of tourist coasts in Southeast Asia. For many atoll island states, sea level
rise is more than just a threat to their tourism; it also determines their survival. In
recent years, assessments of their vulnerability and adaptation have favoured a
more integrative approach of physical and human sciences. Hopefully, this
should result in a better analytical tropical geography that could play an important
role in reducing coastal erosion and assist the small island states.

mobilisation in coastal lowland acid sulfate soils: Implications of sea level rise for water
quality." Geoderma 160(2): 252-263.
Coastal floodplains are highly vulnerable to inundation with saline water and the
likelihood of inundation will
increase with sea level rise. Sediment samples from floodplains containing coastal
lowland acid sulfate soils
(CLASS) in eastern Australia were subjected to increasing seawater concentration to
examine the probable
effects of sea level rise on acidity and metal desorption. Ten soils were mixed with
synthetic seawater
concentrations varying from 0% to 100% at a solid:solution ratio of 1:10 for 4 h. There
was a slight decrease in
pH (≈0.5 units) with increasing seawater concentration following treatment, yet,
calculated acidity increased
significantly. In most soil treatments, Al was the dominant component of the calculated
acidity pool. Al
dominated the exchange complex in the CLASS and, correspondingly, was the major
metal ion desorbed. In
general, concentrations of soluble and exchangeable Al, Fe2+, Ni, Mn and Zn in all soil
extracts increased with
increasing salinity. Increasing trace metal concentrations with increasing seawater
concentration is attributed
to the combined effects of exchange processes and acidity. The increasing ionic
strength of the seawater
treatments displaces trace metals and protons adsorbed on sediments, causing an
initial decrease in pH.
Hydrolysis of desorbed acidic metal cations can further contribute to acidity and
increase mobilisation of trace
metals. These findings imply that saline inundation of CLASS environments, even by
relatively brackish water
may cause rapid, shorter-term water quality changes and a pulse release of acidity due
to desorption of acidic
metal cations.

in coastal blackbutt forests of southeastern Australia." Austral Ecology 25(1): 83-98.
Periodic low-intensity fire (hazard-reduction burning) is a conspicuous
management strategy in virtually all of Australia‘s dry forest communities where it
is primarily used to reduce fuel levels with the intention of minimising the extent
and severity of wildfires. Little is known, however, about the effects of its
repeated use on natural ecosystems over long periods of time. This study
investigated the long-term effects of frequent low-intensity fire on forest ant
communities by comparing frequently burnt sites with long-unburnt control sites.
While the richness of ant communities remained largely unchanged, the
composition of assemblages differed substantially between treatments. Although
frequent burning apparently resulted in the loss of a substantial number of
species, the overall richness of frequently burnt areas was maintained by the
addition of species not present on unburnt sites. These changes in species
composition were accompanied by major changes in community organisation
(structure) and were considered to be a response to altered habitat conditions,
particularly litter biomass, vegetation structure and patterns of insolation at
ground level. Appropriate fire prescriptions could therefore be applied to
manipulate these habitat elements at a landscape scale to meet both
management and conservation goals. A comparison of pitfall trapping and litter
extraction techniques revealed the importance of a composite sampling strategy,
with 22% of ant species detected only by litter extraction.
