研究领域

I have a wide-ranging mix of interests, particularly concerning the population ecology, community ecology, and physiological ecology of freshwater invertebrates. In particular, I am interested in how the following factors affect the distribution, density, dispersion, and persistence of animal populations: 1) behavioral responses (dispersal and migration, reproductive behavior and parental care, foraging, predator avoidance); 2) ecological interactions, both direct and indirect (predator-prey and competitive interactions, intraspecific and interspecific agonistic interactions); 3) physiological adaptations to changes in the physical environment (particularly respiratory adaptations to temperature, turbidity and hypoxia). Study organisms include: zebra mussels and quagga mussels (Dreissena polymorpha and D. bugensis), snails (numerous spp.), unionid bivalves (numerous spp.), crayfish (multiple spp.), isopod and amphipod crustaceans (Gammarus, Lirceus), waterbugs (Belostoma), and freshwater jellyfish (Craspedacusta).
