Mapping the Dorsal Skin Pigmentation Patterns of Two Sympatric Populations of Ambystomatid Salamanders, <em>Ambystoma opacum</em> and <em>A. maculatum</em> from Northeast Tennessee.
… region, sympatric populations of ambystomatid salamanders <em>A. opacum</em> and <em>A. maculatum</em> were studied in Northeast Tennessee to address a number of questions: i) the extent of sexual size dimorphism (SSD) in both species, ii) what traits influence the dorsal skin pigmentation and …

Landscape Genetics of the Marbled Salamander (Ambystoma Opacum) at Mammoth Cave National Park
… Here I present a landscape genetics study on marbled salamanders (Ambystoma opacum) in highly connected forested habitat at Mammoth Cave National Park. This investigation of gene flow among ponds within a mostly continuous landscape provides data that can be compared with patterns observed in …

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 …

Amphibian Community Similarity Between Natural Ponds And Constructed Ponds Of Multiple Types In Daniel Boone National Forest, Kentucky
… wood frogs (<em>Rana sylvatica</em>) and marbled salamanders (<em>Ambystoma opacum</em>) were almost exclusively found in natural, ephemeral ponds, whereas large ranid frogs (<em>R. clamitans, R. catesbeiana, R. palustris</em>) were only found breeding in permanent, constructed ponds. …

Salamander Mating Behaviors and Their Consequences for Individuals and Populations
… system studies in a little studied species, the marbled salamander (Ambystoma opacum). I studied female mating behavior, sexual selection, and the consequences of polyandry for individual females and salamander populations. I also compared the performance of several statistical approaches for …

Amphibian and plant communities of natural and constructed upland-embedded wetlands in the Daniel Boone National Forest
… natural ephemeral wetlands. Wood frog and marbled salamander larvae are found almost exclusively in natural wetlands and green frog larvae and eastern newts are found in constructed wetlands. It is currently unknown whether plant communities at these constructed wetlands are similar to …

Interactions between Eastern Newts and Wood Frogs in an anthropogenically altered wetland system in eastern Kentucky
… Wood Frogs [<em>Lithobates sylvaticus<em>] and Marbled Salamanders [<em>Ambystoma opacum<em>]). Over the last 25 years, hundreds of wetlands have been constructed within the ridge-top ecosystem as permanent water sources for wildlife (i.e., game species). Consequently, the modified ridge-top …

Amphibian Community Composition And Disease Susceptibility In Ridge-Top Wetlands Of The Daniel Boone National Forest
… such as wood frogs (Lithobates sylvaticus) and marbled salamanders (Ambystoma opacum); these were game wetlands with shallower littoral zones and more complex basin vegetation that mimicked natural wetland characteristics. However, because none of the constructed wetlands were ephemeral, they …
