Electrophoretic Variation In Northern Dusky Salamander Desmognathus fuscus Populations In Eastern North America (Caudata: Plethodontidae)

An electrophoretic analysis was performed on 336 Northern Dusky salamanders (Desmognathus fuscus) from 17 sites in the Eastern US to determine the presence of alternate forms from the piedmont physiographic province. Sites were selected from low (0-239m), medium (240-479m), and, high (>480m) elevations to detect contact zones or range limits if applicable.
