Research in my lab focuses on the evolutionary ecology, physiology and conservation of freshwater fishes. Much of the research utilizes species in the Fundulus notatus species complex (F. notatus, F. olivaceus and F. euryzonus) to address basic questions in evolutionary ecology. The species in this complex are closely related and known to hybridize in numerous replicate hybrid zones throughout their broadly overlapping ranges. Within areas of coexistence, the species usually segregate along the river continuum with areas of hybridization and coexistence focused on confluences. Interestingly, in some areas of the distribution, typical up and downstream distributions may be reversed. Thus, hybrid zones in this system are replicated and replicate hybrid zones vary in the degree of genetic divergence and ecology of the parental species.
