Effects of Timber Harvesting on Terrestrial Salamander Abundance and Behavior
… effects of 7 silvicultural treatments on terrestrial salamander populations at 4 sites in southwest Virginia and West Virginia. The 3 silvicultural treatments with the most canopy removal (4-7 m2 basal area Shelterwood, Leavetree, Clearcut) had significantly fewer salamanders than the …

Terrestrial Salamanders in southern Appalachain Harwood Forests: Relative Abundance, Nutritional Condition, and Response to Silvicultural Practices
… assessing nutritional condition in 3 groups of terrestrial salamanders. We measured variability in species richness and relative abundance before harvest at 5 sites in the Jefferson National Forest of southwest Virginia and compared the effects of 7 silvicultural treatments on terrestrial …

Effects of Forest Regeneration Methods on Salamander Populations in Central Appalachia
In forested ecosystems, salamanders occupy important ecological roles as predator, prey and as potential regulators of ecological processes. The effects of forest management, particularly clearcut harvesting, on salamanders have been well documented; removal of overstory trees negatively affects …

Development and Application of Non-Traditional Vertebrate Models to Investigate Terrestrial Ecological Risk to 2,46-Trinitrotoluene Exposure
… have been challenging, given the variation in terrestrial communities and the values in which policy makers are bound to protect. This has resulted in vague, yet flexible guidance from the U.S. Environmental Protection Agency and other interested parties (e.g., the U.S. Army Corps of Engineers, …

The influence of silvicultural manipulations on plethodontid salamanders
… on how methods of forest management impact salamanders. In this research, I examine how experimental silviculture impacts plethodontid salamander relative abundance and count, and I compare three different body condition indices. Chapter 1 focuses on plethodontid salamander relative …
