Species Delimitation in Desmognathus Salamanders – [Research Assistantship]

Professor: Alex Pyron

Department: Biological Science

Title: Species Delimitation in Desmognathus Salamanders

The Dusky Salamanders, genus Desmognathus, are one of the most diverse and
abundant animals in the eastern forests of the United States. They are
classic study organisms for ecology and behavior. Despite their visibility
and imperilment, we know little about their genetic diversity and
evolutionary history. While there are only 21 currently named species, recent
work using DNA sequencing has revealed at least 45 potential species, which
would more than double the size of the group.

Duties: The research assistant will work with me to collect data and build a
computational model to distinguish between cryptic species of Desmognathus
salamander. Classes in ecology/evolution and experience with statistics are a
