We study the causes, consequences, and maintenance of biological diversity. Our research integrates studies on (1) how interactions between species evolve , (2) what factors promote and constrain microevolutionary processes, especially natural selection, (3) how interactions structure multispecies communities, and (4) which mechanisms promote the long-term maintenance of biological diversity. Our work combines theoretical explorations of these themes with experimental, observational, and meta-analytical studies. Although we have used a variety of study systems, most of our empirical work is conducted using damselflies (an awesome predatory aquatic insect).
