Proteolytic, hemorrhagic, and neurotoxic activities caused by Leptodeira annulata ashmeadii (Serpentes: Colubridae) Duvernoy's gland secretion.

Complex evolution in the Neotropics: the origin and diversification of the widespread genus Leptodeira (Serpentes: Colubridae).

Lineage diversification in the Neotropics is an interesting topic in evolutionary biology but is also one of the least understood. The abiotic and biotic complexity of the region precludes generalizations that can be drawn regarding the historical evolutionary processes responsible for the diversity observed. The snake genus Leptodeira provides an excellent opportunity to investigate such proce...

Notes on the Feeding Behavior and Caudal Luring by Juvenile Alsophis portoricensis (Serpentes: Colubridae)

A case of communal nesting in the Neotropical snake Sibynomorphus mikanii (Serpentes, Colubridae)

Disintegrin, hemorrhagic, and proteolytic activities of Mohave rattlesnake, Crotalus scutulatus scutulatus venoms lacking Mojave toxin.

Venom from the Mohave rattlesnake, Crotalus scutulatus scutulatus, has been reported to be either: (1) neurotoxic; (2) hemorrhagic, or both (3) neurotoxic and hemorrhagic. In this study, 14 Mohave rattlesnakes from Arizona and Texas (USA) were analyzed for the presence of disintegrins and Mojave toxin. All venom samples were analyzed for the presence of hemorrhagic, proteolytic and disintegrin ...

Reproductive biology and diet of Liophis poecilogyrus poecilogyrus (Serpentes, Colubridae) from southeastern Brazil

Received 5 March 2004. Accepted 9 June 2004. Distributed 30 September 2004. Abstract Reproductive biology and diet of Liophis poecilogyrus poecilogyrus (Serpentes, Colubridae) from southeastern Brazil. We describe the reproductive pattern and the diet of Liophis poecilogyrus poecilogyrus based on examination of museum specimens. The snake has an aseasonal reproductive pattern, suggesting multip...
