                   Herbivory on the individual plant
                   is also constrained by ecosystem
                   processes. Environmental
                   conditions affect herbivore activity
                   and thereby influence herbivory
                   on individual plants.
                   Environmental factors such as
                   soil and air temperatures,
                   moisture availability, light
                   availability and precipitation can
                   all influence the ability of an
                   individual plant to respond to
Ecosystem          herbivory.                           Oak-Woodland Ecosystem


                   Spatial distribution of wild oat

HERBIVORY EFFECTS

Herbivory can increase bare
ground and compact soils
resuting in warmer and drier
microclimates, reduced
infiltration and increased
runoff.




Herbivory can influence
decomposition processes and
mineralization rates, the rate or
timing of primary production,
and food web interactions.


Competition from surrounding
plants in a community may
influence a plant's response
to herbivory


Herbivory affects the
abundance, distribution and
dominance of the consumed
population, and may
influence plant reproductive
output, or fitness.
