Abstract
We studied the heat shock response in a coastal plain population of the lungless salamander species Plethodon chlorobryonis. We recorded field body temperatures of salamanders during summer at the Savannah River Ecology Lab, Aiken, South Carolina. We collected specimens and either froze them or returned them to the laboratory and gave them a standard heat shock of 1 hour at 2 [degrees] C below CTMax. Hsp-70 levels of frozen and heat shocked salamanders were determined using ELISA and SDS PAGE. Plethodon chlorobryonis had the highest field body temperatures ever recorded for plethodontid salamanders (33.6 [degrees] C). Tissue analyses from these `hot' salamanders indicate that hsp-70 levels were highly elevated. Plethodon chlorobryonis induced high levels of hsp-70 in response to thermal stress. This ability of P. chlorobryonis to induce and accumulate high levels of hsp-70 may allow them to inhabit the hot coastal plain.
