A Behavioral Syndrome in the Southern Red-Backed Salamander (Plethodon Serratus)
Animals generally are predicted to behave in ways that are presumed to maximize fitness, such as retreating at the sign of a predator or being aggressive in mating competitions and territorial conflicts. However, responses to specific stimuli can be highly variable, which in part can be explained …

Behavioral and Metabolic Responses of the Southern Red-Backed Salamander (Plethodon Serratus) to Predatory Stimuli: Influence of Body Size
In nature, visual cues are limited for southern red-backed salamanders (Plethodon serratus), so chemoreception may be important for predator detection. I conducted experiments to examine the effect of chemical stimuli from predatory ringneck snakes on the foraging behavior and metabolic rates of P. …

The status and distribution of terrestrial amphibians in old-growth forests and managed stands
… My study demonstrated that clearcut harvesting reduces terrestrial amphibian populations by as much as 70%. I suggest that the mechanism behind this pattern is a reduction in the availability of moist microhabitats. In support of this, salamander densities in managed stands were similar to those …

Influence of Physical Stress, Sex, and Body Size on Metabolic Rates of Ozark Zigzag Salamanders, Plethodon Angusticlavius
Ozark zigzag salamanders (Plethodon angusticlavius) are exposed to a variety of stressors, each eliciting a combination of behavioral and physiological responses. One response is an increase in oxygen consumption rate. Individuals were physically stressed to simulate a predatory attack, and oxygen …
