How Do Species Interactions Affect Evolutionary Dynamics Across Whole Communities?

This paper outlines verbal theory, existing evidence and future avenues for studying evolutionary interactions across whole communities. Many thanks to the Biodiversity Research Centre at the University of British Columbia (UBC) for hosting my sabbatical visit. Watching cedar waxwings and hummingbirds from my office window helped inspire this paper. We now need quantitative theory to guide our experiments – watch this space!
