The postglacial adaptive radiation of the threespine stickleback fish forms the basis for much of the research conducted in our laboratory. Laboratory members address questions concerning the evolution of reproductive and antipredator behavior, morphology, and life history in both contemporary and older contexts. A core aspect of this research involves understanding the role of phenotypic plasticity in evolution. Others, working with John Baker, are engaged in conservation research in Massachusetts streams, including study of the globally endangered freshwater mussel, Margaritifera maragaritifera.
