Phylogenetics of Kingsnakes, Lampropeltis getula Complex (Serpentes: Colubridae), in Eastern North America
It is shown that 3 previously recognized subspecies in the eastern United States comprise well-supported monophyletic lineages that diverged during the Pleistocene, indicating shared geographic influences on evolutionary history.
Record length, mass, and clutch size in the nonindigenous Burmese Python, Python bivittatus Kuhl 1820 (Squamata: Pythonidae), in Florida
Pliocene-Pleistocene lineage diversifications in the Eastern Indigo Snake (Drymarchon couperi) in the Southeastern United States.
A cryptic new species of Indigo Snake (genus Drymarchon) from the Florida Platform of the United States.
A lineage that occurs along the Gulf coast of Florida and Mississippi as a new species, Drymarchon kolpobasileus, is described, distinguished from D. couperi by a suite of morphological features, including a shorter and shallower head, deeper and shorter 7th infralabial scales, and shorter temporal scales.
Molecular phylogeny of Caribbean dipsadid (Xenodontinae: Alsophiini) snakes, including identification of the first record from the Cay Sal Bank, The Bahamas.
Molecular data agree with some aspects of morphology supporting identification of this specimen as the Cuban Racer, Cubophis cantherigerus cantherigersus (Bibron 1840), a species previously regarded as endemic to Cuba.
Burmese Python (Python bivittatus)
CONFIRMATION OF INTRODUCED A GAMA PICTICAUDA IN FLORIDA BASED ON MOLECULAR ANALYSES
As of 2010, Florida had the largest number of introduced and established non-indigenous herpetofaunal species in the world. With the advent of molecular methodologies, researchers now are able to…
Confirmation of introduced Louisiana pinesnakes, Pituophis ruthveni, in Florida based on molecular analyses
Two recently collected Pituophis specimens in Miami-Dade County, Florida, were examined using molecular analyses and no molecular evidence was found supporting the recognition of P. ruthveni as a separate species, but adding other mtDNA and nuclear DNA genes might provide needed data for distinguishing between these two named taxa.
Reintroduced and Resident Amphibian Community Dynamics and Health Response to Oak Woodland Restoration
We are examining amphibian demographic, community, and health responses to oak restoration via canopy gap management and invasive understory removal in northern Illinois. Objectives include…
A new species of Erythrolamprus (Serpentes: Dipsadidae: Xenodontini) from the savannas of northern South America
This work reassess the taxonomic status of specimens previously identified as Erythrolamprus poecilogyrus schotti from the savannah habitats of Roraima state, northern Brazil, Guyana, and Bolívar state, Venezuela and concludes that they represent a distinct, diagnosable and reciprocally monophyletic taxon.
