Theses, Dissertations and Capstones

Being lungless, plethodontid salamanders respire through their skin and are especially sensitive to environmental disturbances. Habitat fragmentation, low abundance, extreme habitat requirements, and a narrow distribution of less than 70 miles in length, makes one such salamander, Plethodon punctatus, a species of concern (S1) in West Virginia. To better understand this sensitive species, day and night survey hikes were conducted through ideal habitat and coordinate data as well as tail tips (10 to 20 mm in length) were collected. DNA was extracted from the tail tips and polymerase chain reaction (PCR) was used to amplify mitochondrial 16S rRNA gene fragments. …
