Research Interests:
I have two primary research interests: mating system evolution and speciation. For my dissertation I am studying how high male mating costs may have affected reinforcement, and thus speciation, in the Hawaiian cricket genus Laupala. To do this, I am defining species boundaries and determining the extent of hybridization using nDNA and mtDNA sequences, I am documenting patterns of prezygotic isolation between sympatric and allopatric species and populations, and finally I am testing how high male mating costs--due to spermatophore investment--might be changing the direction in which reinforcement acts in this genus. Results of this work will hopefully shed some light on how speciation has occurred so rapidly in this genus and may also serve to elucidate a new pattern for reinforcement.
