A Species-Level Phylogeny of Extant Snakes with Description of a New Colubrid Subfamily and Genus
Background With over 3,500 species encompassing a diverse range of morphologies and ecologies, snakes make up 36% of squamate diversity. Despite several attempts at estimating higher-level snakeExpand

Ecological divergence in the yellow-bellied kingsnake (Lampropeltis calligaster) at two North American biodiversity hotspots.
Several biogeographic barriers in the Eastern Nearctic appear to reduce gene flow among populations of many species in predictable ways, however these patterns used to infer process of divergence mayExpand

Predicting community structure in snakes on Eastern Nearctic islands using ecological neutral theory and phylogenetic methods
Predicting species presence and richness on islands is important for understanding the origins of communities and how likely it is that species will disperse and resist extinction. The equilibriumExpand

The phylogenetic position and taxonomic status of the Rainbow Tree Snake Gonyophis margaritatus (Peters, 1871) (Squamata: Colubridae) .
Molecular phylogenies have provided strong evidence for clarifying the taxonomy of groups with ambiguous morphological traits, thus avoiding potentially misleading conclusions based on evolutionaryExpand

First record of ophiophagy in the widely distributed snake Leptodeira septentrionalis (Kennicott, 1859) (Ophidia, Colubridae)
trionalis (Kennicott, 1859) is a widely distributed oviparous dipsadine snake with a range from extreme southern Texas to northwestern Peru. This nocturnal arboreal genus is known to eat primarilyExpand

A new non-coastal record for the Pine Woods Littersnake, Rhadinaea flavilata Cope, 1871 (Squamata: Colubridae), in Russell County, Alabama, USA
We found a single specimen of Rhadinaea flavilata in Russell County, Alabama, in an area composed of primarily pine plantation habitat. This record is 200 km north of the currently recognized rangeExpand

Ecological divergence across two North American biodiversity hotspots in the Yellow- Bellied Kingsnake (Lampropeltis calligaster)
Several biogeographic barriers in the Eastern Nearctic appear to reduce gene flow among populations of many species in predictable ways, however these patterns used to infer process of divergence mayExpand
Biogeographic barriers, Pleistocene refugia, and climatic gradients in the southeastern Nearctic drive diversification in cornsnakes (Pantherophis guttatus complex)
The southeastern Nearctic is a biodiversity hotspot that is also rich in cryptic species. Numerous hypotheses (e.g., vicariance, local adaptation, and Pleistocene speciation in glacial refugia) haveExpand
