Professional Interests of Rick Relyea

Wood Frog For effective conservation of natural communities, we have to understand how communities work and how they are affected by human impacts. To accomplish this goal, my lab works at the interface of several biological fields, including ecology, evolution, animal behavior, development, toxicology, and biochemistry. By integrating our thinking (and our experiments) across these diverse biological disciplines, we can develop exciting new insights that improve our basic understanding of ecological communities as well as making discoveries that are important to conservation. I have applied this approach to my studies of aquatic communities in which I work in a variety of environments (from highly controlled laboratory experiment to pond mesocosms and natural field sites) and focus on a diversity of aquatic organisms including amphibians, fish, insects, snails, and other aquatic invertebrates.

My research program can be broken down into three broad areas:

The effects of pesticides on amphibians and aquatic communities
The ecology and evolution of phenotypic plasticity, including how predators and competitors affect an organism's behavior, morphology, and life history
Long-term monitoring of aquatic communities
