My dissertation research will focus on evaluating hybrid zone dynamics between Nelson’s and Saltmarsh Sparrows in order to better understand the interactions between the two species and the conservation and evolutionary implications of hybridization. To do this, I am using an integrative approach that combines field and genetic data, including the use of survival rates, habitat and simulation data, and conserved and neutral genetic markers. I am specifically interested in hybrid fitness and the impacts of natural selection and habitat associations in shaping patterns of introgression.
