Evolution of neural systems and behavior, Evolution of prezygotic isolation among species and its underlying neurological and genomic basis

My lab is broadly interested in the evolution of behavior and its underlying genomic and neurological bases in fish. We tend to focus on variation that manifests among populations within species or among closely related species of fish - particularly killifish, darters, and bass. Currently, the lab is predominantly interested in two main themes.

The first revolves around developing mathematical models of visual systems so that the visual perception can be estimated for species whose visual systems differ from that of humans. We focus on species with retinas with as many as five cone cell types (killifish) or with as few as two (bass). We then ask whether models that combine critical parameters of the visual system and lighting environment explain the types of colors that animals have in nature.

The second theme revolves around questions of speciation and the evolution of pre-zygotic isolation. Our recent work indicates that reinforcement (selection to mate with conspecifics in areas of sympatry) is rampant among many fish systems and that genomic arrangements are often evolved. Projects along these lines involve dissections of the genetic basis of preference.
