Species Interactions &
How do species coexist within communities? What determines when species overlap versus segregate their distributions? How do interactions among species change with time since sharing a common ancestor? All of these questions are of central importance to our understanding of patterns of local diversity and limits on the distributions of species.
We use song playback and reciprocal removal experiments coupled with observations from nature and comparative studies to test ideas of how species interact and coexist. Most of our work has been conducted on birds, but we're expanding to insects and plants.
