Twenty-four specimens of Pantherophis guttatus (Linnaeus) (corn snake) from North Carolina were examined for endoparasites. Fourteen species of helminths (2 cestodes, 10 nematodes, 2 acanthocephalans) and 1 pentastome are reported, representing 14 new host records and 1 new geographic distribution record. No trematodes were found, and the salvaged...

Wetland condition assessment is often performed by land managers, federal and local governments, and conservation organizations to document current condition and potentially take action to protect or restore valuable wetland resources. These condition assessments often include data collection or surveys of biotic communities such as vegetation, mac...

Twenty-eight specimens of Pantherophis alleghaniensis Holbrook (eastern rat snake) from North Carolina were examined for gastrointestinal helminths. Thirteen species of helminths (3 trematodes, 2 cestodes, 7 nematodes, and 1 acanthocephalan) are reported, representing 8 new host records and 1 new geographic distribution record. Immature physalopter...

Cryptic species are a challenge for systematics, but their elucidation also may leave critical information gaps about the distribution, conservation status, and behavior of affected species. We use the leopard frogs of the eastern U.S. as a case study of this issue. We refined the known range of the recently described Rana kauffeldi, the Atlantic C...

Morphological and color characters from photographic analysis of 220 leopard frogs (Rana spp.) in the eastern U.S. Frogs were identified using genetics and designated as “pure” if they had a 90% or greater match with a single species; individuals with a species match between 10% and 90% were designated as admixed. Sample sizes for each character ar...

Context Accurate estimates of population density are a critical component of effective wildlife conservation and management. However, many snake species are so secretive that their density cannot be determined using traditional methods such as capture–mark–recapture. Thus, the status of most terrestrial snake populations remains completely unknown....

We surveyed for helminth parasites salvaged specimens of 27 Agkistrodon contortrix (Copperhead), 4 Agkistrodon piscivorus (Cottonmouth), and 7 Crotalus horridus (Timber Rattlesnake) collected between 2003 and 2010 from various locations in North Carolina. We detected 10 previously described helminths (2 trematodes: Ochetosoma kansensis, Travtrema s...

The Southern Hognose Snake (Heterodon simus) is a poorly known and declining species in the southeastern U.S. We conducted road surveys from 1985-2012 and accumulated 764 observations of this species from the sandhills and southeastern Coastal Plain of North Carolina. Here, we report information on the size, sex ratio, diet, diel and seasonal activ...

Terrestrial Movements of the Red-bellied Mudsnake (Farancia abacura) and Rainbow Snake (F. erytrogramma) Red-bellied Mudsnakes (Farancia abacura; Fig. 1A) and Rain-bow Snakes (Farancia erytrogramma; Fig. 1B) are relatively large species with geographic distributions restricted to the south-eastern United States. Both species are highly associated w...

Nesting behavior in the Northern Pine Snake (Pituophis m. melanoleucus) is poorly documented outside of the New Jersey Pine Barrens. Two natural nests of P. m. melanoleucus are described from the North Carolina Sandhills. One was modified from a pre-existing subterranean refugium, and was also used by at least one adult male; one adult female; and...

The first confirmed record of dicephaly in the eastern ribbon snake, Thamnophis s. sauritus, is reported. A juvenile female, wild-caught in North Carolina, was maintained in captivity for 1,050 days. Some behavioral observations are described.

The river frog (Rana heckscheri), a large ranid occurring in aquatic and riparian habitats in the southeastern United States, reaches the northern edge of its range in southeastern North Carolina, where it has been recorded historically from a few scattered localities in the Lumber and Cape Fear river systems. Currently listed by the state as a spe...
