The White-shouldered Fairywren (Malurus alboscapulatus) is a tropical passerine bird distributed across much of New Guinea. White-shouldered Fairywrens are among few species of fairywren with exclusively tropical distributions and differ from better studied congeners in Australia because subspecies vary by female, but not male, coloration and morph...

Background The amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), has been implicated as a primary cause of decline in many species around the globe. However, there are some species and populations that are known to become infected in the wild, yet declines have not been observed. Here we conducted a yearlong capture-mark-recapture stud...
Article

We studied the population-genetic structure of the Diamondback Terrapin (Malaclemys terrapin pileata) in Louisiana and used data from previous studies to compare our results with rangewide patterns of genetic diversity. We analyzed blood plasma to examine the contaminant load in Louisiana terrapins in the wake of the 2010 Deepwater Horizon oil spil...
Article
Full-text available
There has long been debate over alternatives to toe-clipping as an individual marking method in anurans. Alternative methods include visible implant elastomer (VIE) tags and passive integrated transponder (PIT) tags. VIE tags are low cost, easy to insert and have been used successfully in reptiles, fish and salamanders without tag loss or movement....
Article
Full-text available
The amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), has been linked to amphibian declines and extinctions worldwide. The pathogen has been found on amphibians throughout eastern North America, but has not been associated with mass die-offs in this region. In this study, we conducted laboratory experiments on the effects of Bd infecti...
Article
Full-text available
Batrachochytrium dendrobatidis, a pathogenic chytrid fungus implicated in worldwide amphibian declines, is considered an amphibian specialist. Identification of nonamphibian hosts could help explain the virulence, heterogeneous distribution, variable rates of spread, and persistence of B. dendrobatidis in freshwater ecosystems even after amphibian...
Article
Full-text available
Little is known about the impact that the pathogenic amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), has on fully aquatic salamander species of the eastern United States. As a first step in determining the impacts of Bd on these species, we aimed to determine the prevalence of Bd in wild populations of fully aquatic salamanders in th...
Article
Full-text available
Amphibians worldwide are experiencing devastating declines, some of which are due to the amphibian chytrid fungus (Batrachochytrium dendrobatidis, Bd). Populations in the southeastern United States, however, have not been noticeably affected by the pathogen. The green treefrog (Hyla cinerea) is abundant and widespread in the southeastern United Sta...

Article
Full-text available
The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) has been implicated in amphibian declines worldwide. In vitro laboratory studies and those done on wild populations indicate that Bd grows best at cool temperatures between 17 and 25 degrees C. In the present study, we tested whether moderately elevating the ambient temperature to 30...
Article
Full-text available
Hybrid zones have yielded considerable insight into many evolutionary processes, including speciation and the maintenance of species boundaries. Presented here are analyses from a hybrid zone that occurs among three salamanders –Plethodon jordani, Plethodon metcalfi and Plethodon teyahalee– from the southern Appalachian Mountains. Using a novel sta...
Article
Full-text available
This dissertation includes three studies that focus on the evolution of salamanders in the Plethodon glutinosus group (family Plethodontidae), that are found throughout much of the eastern United States. The first study explores species delimitation in taxonomically problematic groups and then, in that context, examines the long and contentious tax...

Roads may be one of the most common disturbances in otherwise continuous forested habitat in the southern Appalachian Mountains. Despite their obvious presence on the landscape, there is limited data on the ecological effects along a road edge or the size of the "road-effect zone." We sampled salamanders at current and abandoned road sites within t...
