Evolution of Reproductive Isolation in Daphnia

My interests lie at understanding the mechanisms behind speciation and reproductive isolation. For populations to diverge into new species, reproductive isolation must develop to prevent populations from exchanging genetic material between them. I am interested in studying the strengths of reproductive isolating barriers between two closely related species, Daphnia pulex and Daphnia pulicaria. The two species are found to be isolated by habitat and have differences in their timing of reproduction; however, not much is known about other reproductive barriers that have an impact on isolating these two species. With this understanding of reproductive isolation, I aim to examine how reproductive barriers are maintained and persist in intermediate metal contaminated environments in the Sudbury region.
