Trees in Competition
        One of the decisive factors for the survival
        of forest trees is how well they can compete
        against their tree neighbours

      n commerce, companies succeed
      against the competition by using
      resources efficiently. Similar prin-
   ciples can also be observed in the
   competition between forest trees.
   Whether a sapling is able to survive
   is primarily decided by its ability to
   extract water, nutrients and, in par-
   ticular, light energy from the sun for
   photosynthetic carbon fixation from
   its surroundings, and then to make
   use of these resources. To what ex-
   tent plants can take up the various
   resources is decided by the amount
   of competition put up by neighbour-
   ing plants and by the plant’s ability
   to fend off parasites. The balance of
   the competitive uptake of resources
   and defence of these resources
   against animals, which eat plants,
   and parasitic micro-organisms,
   which attack them, is a measure of
   the plant’s “fitness”. This “fitness”
   is also decisive for the plant’s ability
   to reproduce.

gets this energy from the oxygen
and nutrients in the blood. The
heart therefore needs an adequate
blood supply to work properly. The
blood initially passes from the large
coronary blood vessels running
across the surface of the heart,
through smaller arteries and into
the tiniest branchings inside the
cardiac muscle, the capillaries.
Since these capillaries are very thin-
walled and lie deep inside the car-
diac muscle, this is where the mass
transfer takes place. Oxygen and
other vital substances are passed
from the capillaries into the sur-
rounding tissue, while in the other
direction “metabolic waste” passes
from the tissue into the blood, where                                                                                           15

        Some of the most important building blocks of life were carried to Earth by
        meteorites and comets, according to studies by a Franco-German team of chemists

A

       surviving from the Murchi-
       son meteorite may be re-
sponsible for changing our view of
the world by proving that life may
not have originated on Earth at all.
Some of life’s critical components
came from outer space and were
brought to Earth by meteorite
strikes, according to new studies by
a Franco-German team of chemists
from the University of Bremen in
Germany and the University of
Nice-Sophia Antipolis in France.
The researchers were able to show
that the meteorite was carrying so-
called di-amino acids that are
thought to have played a key role in
the emergence of life. Scientists are
also hoping to confirm these results
on the Rosetta Comet Mission being
undertaken by the European Space
Agency.
   Since 1953, when Watson and
Crick identified deoxyribonucleic
acid, or DNA for short, as the carrier
of genetic information and discov-
ered the unique information stor-

there has been speculation on the
origins of DNA and of life itself.
Theorists currently believe that
DNA and proteins are composed of
molecular building blocks. Various
amino acids, for example, are re-

dicate far greater amounts of biolog-
ical activity in the surface waters
than is the case today. These find-
ings point to a considerable produc-
tion of plants during this period.
   Sand and individual silicate parti-
cles, possibly transported to the Arc-
tic by ice floes and icebergs, appear
regularly during the last 15 million
years. This leads to the conclusion
that sea ice has played a key role in
the climate of the Arctic during this
period. The question of whether the
Arctic Ocean was frozen over only
in winter or throughout the year can
only be answered by further sedi-
mentological and micropalaeonto-
logical study. Clear evidence of im-
mense ice sheets on the surround-
ing continents has not yet been
found in the sediments.
   Particularly spectacular was the
discovery of individual silicate
stones from the Middle Eocene, the
period between 40 and 46 million
years ago. They must have been
transported to the Arctic from the
surrounding land by ice floes and
icebergs, indicating that climatic
conditions were cold at the same
time that the western Antarctic was
just starting to form a continental ice
cover. This is astonishing. Scientists
had previously believed that the ini-
tial formation of ice at the Antarctic
had occurred much earlier than at
Arctic latitudes. Does this mean we
have to rethink our view of the
world climate? Did the ice covers
appear in both the Arctic and
Antarctic simultaneously? For now,
these questions can be addressed
with no more than speculation.

     sponsible for promoting research in Germany. According to its statutes, the DFG serves        Josef-Schneider-Straße 2,
     all branches of science and the humanities. The DFG supports and coordinates research         97080 Würzburg
     projects in all scientific disciplines, in particular in the areas of basic and applied re-   Prof. Dr. Thomas Christaller
     search. Particular attention is paid to promoting young researchers. Researchers who          Dr. Ansgar Bredenfeld
     work at a university or research institution in Germany are eligible to apply for DFG         Fraunhofer Institut für Autonome
     funding. Proposals will be peer reviewed. The final assessment will be carried out by re-     Intelligente Systeme (AIS),
     view boards, the members of which are elected by researchers in Germany in their indi-        Schloss Birlinghoven,
     vidual subject areas every four years.                                                        53754 Sankt Augustin
     The DFG distinguishes between the following programmes for research funding: In the
     Individual Grants Programme, any researcher can apply for financial assistance for an         Albert Gerdes
     individual research project. Priority Programmes allow researchers from various re-           DFG-Forschungszentrum Ozeanränder
     search institutions and laboratories to cooperate within the framework of a set topic or      an der Universität Bremen,
     project for a defined period of time, each working at his/her respective research institu-    – Öffentlichkeitsarbeit –,
     tion. A Research Unit is a longer-term collaboration between several researchers who          Postfach 330 440, 28334 Bremen
     generally work together on a research topic at a single location. In Central Research Fa-     Dr. Reinhard Grunwald
     cilities there is a particular concentration of personnel and equipment that is required to   Generalsekretär der Deutschen
     provide scientific and technical services.                                                    Forschungsgemeinschaft,
     Collaborative Research Centres are long-term university research centres in which sci-        Kennedyallee 40, 53175 Bonn
     entists and academics pursue ambitious joint interdisciplinary research undertakings.         Tobias Lagatz
     They are generally established for a period of 12 years. In addition to the classic Collab-   Katholisch-Theologische Fakultät,
     orative Research Centres, which are concentrated at one location and open to all subject      Universität Münster,
     areas, the DFG also offers several programme variations. Transregional Collaborative          Johannistraße 8-10, 48143 Münster
     Research Centres allow various locations to cooperate on one topical focus. Cultural
     Studies Research Centres are designed to support the transition in the humanities to an       Dr. Jens Matthiessen
     integrated cultural studies paradigm. Transfer Units serve to transfer the findings of        Alfred-Wegener-Institut für
     basic research produced by Collaborative Research Centres into the realm of practical         Polar- und Meeresforschung,
     application by promoting cooperation between research institutes and users.                   Postfach 12 0161, 27515 Bremerhaven
     DFG Research Centres are an important strategic funding instrument. They concentrate          Prof. Dr. Rainer Matyssek

     internationally visible research priorities at research universities.                         Dr. Thorsten E. E. Grams
     Research Training Groups are university training programmes established for a specific        Department für Ökologie,
     time period to support young researchers by actively involving them in research work.         Wissenschaftszentrum Weihenstephan,
     This focuses on a coherent, topically defined, research and study programme. Research         Technische Universität München,
     Training Groups are designed to promote the early independence of doctoral students           Lehrstuhl für Ökophysiologie
     and intensify international exchange. They are open to international participants. In In-     der Pflanzen,
     ternational Research Training Groups, a jointly structured doctoral programme is of-          Am Hochanger 13, 85354 Freising
     fered by German and foreign universities.

     Other funding opportunities for qualified young researchers are offered by the Heisen-        Université de Nice-Sophia Antipolis,
     berg Programme and the Emmy Noether Programme.                                                Laboratoire Arômes,
