The biotic diversity of the grasslands has historically supported a diverse assemblage of species.
In addition to their role in plant defence, both genes are involved in the plant response to the environment and their expression is regulated by biotic and abiotic agents.
Aquatic ecologists have emphasized the role of biotic interactions on body size distributions.
The approach is from the community level, highlighting physical and biotic interactions at varying spatial scales.
The effectiveness of exclusion through pore size is relatively easy to demonstrate for biotic pollinators by direct observation.
And how have we put our particular gifts to use in our biotic community here on planet Earth?
Development of models of intraspecific body size variation incorporating abiotic and biotic factors would be useful.
Certain types of ecosystems and biotic communities, such as tropical rain forests and wetlands, might completely disappear.
There is little evidence of equilibrium in many natural systems, the environment is always changing and abiotic and biotic evolution is part of that change.
Numerous interacting abiotic and biotic factors have profound effects on nest sites and incubating females.
