KARYOLOGY OF NORTH AMERICAN NATRICINE SNAKES (FAMILY COLUBRIDAE) OF THE GENERA NATRIX AND REGINAFour species of the water snake genus Natrix have a distinctly different pattern of chromosomal morphology than found in two species of the related genus Regina. Natrix all have a karyotype with seven ...
This paper focuses on the phylogenetic relationships of eight North American caenophidian snake species (Carphophis amoena, Contia tenuis, Diadophis puncta... T Pinou,S Vicario,M Marschner,... - 《Molecular Phylogenetics & Evolution》 被引量: 90发表: 2004年 Relict Caenophidian Snakes of North...
North America is home to more than 30 species and subspecies of venomous snakes (Table 1). These fall within two snake families: the Viperidae and Elapidae. The majority of human envenomations occurring in the United States (US) result from bites by members of the subfamily of Viperids known...

Little is known about life-history strategies of this species in North American environments. We report the first discovery of a Northern Snakehead nest in North America and discuss some of its nesting habits.Adult Northern Snakeheads constructed a circular nest in a patch of dense Hydrilla ...
EasternIndigo snakesare the largest snake species native to North America. These non-venomous snakes live in the southeastern United States. Slenderblind snakes, also known as thread snakes, are some of the smallest snakes found in North America. Because of their size and appearance, it’s easy...
, one of several North American reptiles in the pet trade. Mixed methods delineated what aspects of hognose biology facilitate their trade, what social and economic sites define their commercialization, and how the snake's natural history is dynamically embedded within them. Interviews with breeders...
Species divergence and their boundaries are therefore maintained at those loci. The East and FL lineages meet in a hybrid zone in northern Florida that has estimated width of 167 km, which is similar in size to other snake clines (Kindler et al. 2017; Burbrink et al. 2021; Fritz et ...
An abundant fossil record of the snake clade Scolecophidia exists in Europe; however, the minute snake is noticeably absent in reports about the North American Paleogene and Neogene. Presented here are four localities from Florida, USA, that contain scolecophidian remains older than the Pleistocene...
Snakeheads distributions were correlated with thermal factors, whereas those of Asian carps were related mainly to precipitation. Predicted suitable ranges for these nonindigenous species can be divided into three main areas: Mexico and the southern United States (five species); Mexico and the United...
