Although the availability of food resources affects a wide range of ecological and evolutionary processes, its role in generating patterns in natural systems remains largely unresolved. Elucidating the importance of resource availability should be made easier by the development of techniques that...
Community convergence across biogeographically distinct regions suggests the existence of key, repeated, evolutionary mechanisms relating community characteristics to the environment. However, convergence studies at the community level often involve only qualitative comparisons of the environment...
We present empirical evidence that the direct and indirect effects of species richness on ecological processes depend on a system's disturbance regime. We manipulated the number of species of freshwater suspension feeders (net-spinning caddisflies) in laboratory stream mesocosms where communities...
