Landscape Genetics of the Marbled Salamander (Ambystoma Opacum) at Mammoth Cave National Park
… 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 more fragmented …

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.
… in Appalachian 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 …

An assessment of a herpetofaunal community in Hamilton, County, Tennessee: baseline ecology, species richness, and relative abundance
… all study years due to large sample sizes of ambystomatid salamanders relative to all other species. Body sizes of Ambystoma were larger in females, and sex ratios of all Ambystoma were significantly male-biased in all study years except one female-biased sample of Ambystoma opacum (2009). …

Size Structure and Intraguild Interactions between Two Ambystoma Species
… 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 at a similar size …

Biotic and abiotic influences on aggressive interactions within larval <i> Ambystoma</i> assemblages
… two species of intraguild (IG) predators, <i>Ambystoma opacum</i> and <i>A. tigrinum</i>, and their shared intraguild prey, <i>A. maculatum</i>. All species exhibited similar ontogenetic patterns of aggression, characterized by peaks of aggression early in development and subsequent gradual …

Amphibian Community Similarity Between Natural Ponds And Constructed Ponds Of Multiple Types In Daniel Boone National Forest, Kentucky
… 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. Habitat predictors for some …

Salamander Mating Behaviors and Their Consequences for Individuals and Populations
… 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 analyzing genetic …

Interactions between Eastern Newts and Wood Frogs in an anthropogenically altered wetland system in eastern Kentucky
… 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 ecosystem contains hundreds …

Amphibian Community Composition And Disease Susceptibility In Ridge-Top Wetlands Of The Daniel Boone National Forest
… (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 did not exactly …

Amphibian and plant communities of natural and constructed upland-embedded wetlands in the Daniel Boone National Forest
… (Lithobates sylvaticus) and marbled salamanders (Ambystoma opacum) and constructed wetlands were associated with green frogs (L. clamitans), eastern newts (Notophthalmus viridescens), and spotted/Jefferson salamanders (A. maculatum, A. jeffersonianum). Four-toed salamanders (Hemidactylium …
