Comparative Morphometrics of the Sacral Vertebra in <em>Aneides</em> (Caudata: Plethodontidae).
<p>The genus <em>Aneides</em> (Caudata: Plethodontidae) is an arboreal salamander with a prehensile tail and a distribution that spans North America. It is hypothesized that adaptations for arboreality will be visible in the osteology of the sacral vertebra either by qualitative analysis or linear …

Assemblages of salamanders (Family Plethodontidae) in CWA 305(b) fully-supporting, partially-supporting, and non-supporting streams on Walden's Ridge, Tennessee
Surface mining throughout the southeastern United States leading to acid mine drainage (AMD) has caused significant declines in plethodontid salamander communities in AMD affected streams. The Clean Water Act (CWA) requires that each navigable body of water in the United States be assigned a use …

Survey and Comparison of Amphibian Assemblages in Two Physiographic Regions of Northeast Tennessee.
… 1999 to May 2000).</p> <p>Nine caudate (Plethodontidae) and one anuran species (Ranidae) were found in John's Bog. Seven caudate (Ambystomatidae, Plethodontidae, Salamandridae) and five anuran species (Hylidae, Ranidae) were found in Henderson Wetland. Assemblages were compared using an …

RESISTANCE AND RESILIENCE OF STREAM SALAMANDER POPULATIONS TO DISTURBANCE
… first-order streams. Stream salamanders (Family Plethodontidae) represent the dominant vertebrate group and play important ecological roles in first-order streams, although they have often been neglected in previous studies on the effects of disturbance on system ecosystems. It was hypothesized …

Salamanders of the Mio-Pliocene Gray Fossil Site, Washington County, Tennessee.
… taxa from three modern families (Ambystomatidae, Plethodontidae, and Salamandridae) supporting the woodland-pond interpretation of the site. All specimens represent the earliest record of their respective families in the Appalachian Mountains; with the <em>Notophthalmus</em> sp. vertebrae being …

Social behavior and kinship in the four-toed salamander, Hemidactylium scutatum
… especially North American members of the family Plethodontidae, are at risk of local extirpation because they persist in small, isolated populations due to specialized habitat requirements and limited dispersal ability. To effectively conserve and manage such species, factors influencing …

Proximate Causes of Alternative Reproductive Tactics in Blue Ridge Two-Lined Salamanders (Eurycea cf. wilderae)
<p>Alternative reproductive tactics (ARTs) refer to discrete variation in reproductive behavior between members of a sex and within a species. ARTs are present in Blue Ridge two-lined salamanders (<em>Eurcyea</em> cf. <em>wilderae</em>) in the form of male polymorphism. Two male morphs exist: …

Genetic, Morphological, and Behavioral Analysis of the Oklahoma Salamander (Eurycea Tynerensis) in Southwestern Missouri
I investigated populations of Eurycea tynerensis which differed in coloration and life history mode. Using morphometrics and behavioral trials, I tested two sympatric color morphs for the presence of a cryptic species. I also obtained sequence data from the mitochondrial cytochrome-b gene of 21 …

Natural History and Conservation of Bolitoglossine Salamanders in Central Panama
<p>I conducted a mark-recapture study to assess the natural history of a Neotropical salamander community in three discrete 4–6 week sampling periods at Chorro Las Yayas, a protected natural area of about 8000 m2 in central Panama, during an extended drought. I captured 87 Bolitoglossa biseriata, …
