Research interests
The broader questions of my research involve the maintenance of species boundaries and hybrid zone dynamics. Hybrid zones have long been seen as “windows on the evolutionary process,” and are excellent systems in which to address the genetics of species boundaries. Salamanders of the family Plethodontidae are the most diverse and speciose of any salamander group in the world, comprising about two-thirds of all described species. The Southern Appalachians is one of two centers of diversity for this remarkable clade and contains numerous instances of incipiently diverging lineages. This makes the region well suited for studies of evolution, and especially of species boundaries. My study system is a series of hybrid zones among three species of plethodontids – Plethodon jordani, P. metcalfi and P. teyahalee – in the Great Smoky and Balsam Mountain Ranges of North Carolina. My immediate research questions incorporate both molecular and morphological markers, and are focused on the introgression of presumably positively selected traits.
