Virginia’S Amphibians: Status, Threats And Conservation, Jennifer Sevin, John D. Kleopfer Oct 2015

Virginia’S Amphibians: Status, Threats And Conservation, Jennifer Sevin, John D. Kleopfer

Virginia Journal of Science

Virginia’s diverse environments support 84 amphibian species (anurans and caudates), making it the third highest state in terms of species richness. However, the Commonwealth matches the global trend in declining amphibian populations with over one-third of its amphibian species in conservation need. The Species of Greatest Conservation Need included in the most recent Virginia Wildlife Action Plan cut across amphibian families and ecoregions. It is challenging to ascertain the exact cause of most of the population declines. In one degree or another, all of the global threats to amphibians exist within Virginia’s borders. While an active research program on amphibians …


Amphibian And Small Mammal Assemblages In A Northern Virginia Forest Before And After Defoliation By Gypsy Moths (Lymantria Dispar), Joseph C. Mitchell Jan 2015

Amphibian And Small Mammal Assemblages In A Northern Virginia Forest Before And After Defoliation By Gypsy Moths (Lymantria Dispar), Joseph C. Mitchell

Virginia Journal of Science

The introduced European gypsy moth (Lymantria dispar) caused substantial defoliation and mortality of oak trees along the North Fork of Quantico Creek in Prince William Forest Park, Prince William County, Virginia, U.S.A., in 1989 and the early 1990s. Results of a drift fence/pitfall study conducted in 1988 were compared to those obtained from the same technique in the same areas in 1993 to elucidate whether the amphibian and small mammal assemblages had changed over time. Number of Lithobates sylvaticus increased significantly in 1993, but the numbers of Lithobates clamitans and Plethodon cinereus were significantly higher in 1988. Total …
