Connectivity, metapopulation dynamics, and genetic structure of tiger salamanders in a heterogeneous landscape
… population dynamics and genetic structure of tiger salamanders (Ambystoma tigrinum tigrinum) in an agricultural landscape in Illinois. First, I assessed the degree to which matrix heterogeneity influences A. tigrinum movement behavior. Using a field experiment, I showed that a physiological …

Size Structure and Intraguild Interactions between Two Ambystoma Species
… in temporary pond ecosystems between marbled salamanders (<em>Ambystoma opacum</em>) and tiger salamanders (<em>Ambystoma tigrinum</em>) using an outdoor mesocosm experiment. I hypothesized that 1) <em>A. opacum</em> survivorship and growth would be negatively impacted when both species start …

A Study of Habitat Selection and Fluctuating Asymmetry of <em>Amybstoma tigrinum</em> at Henderson Island Wildlife Management Area in Jefferson County TN.
<p>Studies were conducted on a population of tiger salamanders, <em>Ambystoma tigrinum</em>, at Henderson Island Wildlife Management Area in Jefferson County, TN. Tests were conducted to locate the nonbreeding habitat of the salamanders and to detect any difference in fluctuating asymmetry (FA) …

Chemically-mediated prey responses: invasive brook stickleback induced changes in behavior and life history of larval long-toed salamanders
… from garter snakes (Thamnophis elegans), tiger salamanders (A. tigrinum) and brook stickleback (Culaea inconstans), which had been fed a larvae-diet of A. macrodactylum or a null-diet of earthworms (Lumbricus terrestris), and measured subsequent changes in A. macrodactylum behavior. A. …

Development and Application of Non-Traditional Vertebrate Models to Investigate Terrestrial Ecological Risk to 2,46-Trinitrotoluene Exposure
… in a terrestrial salamander: Ambystoma tigrinum (tiger salamanders). A. tigrinum was chosen since they are exclusively carnivorous, relatively long-lived, have a thin integument, and are large enough to investigate individual effects. These investigations were designed to mimic natural conditions …
