A nesting of vipers: Phylogeny and historical biogeography of the Viperidae (Squamata: Serpentes).
Despite their medical interest, the phylogeny of the snake family Viperidae remains inadequately understood. Previous studies have generally focused either on the pitvipers (Crotalinae) or on the OldExpand
Coevolution of diet and prey-specific venom activity supports the role of selection in snake venom evolution
The processes that drive the evolution of snake venom variability, particularly the role of diet, have been a topic of intense recent research interest. Here, we test whether extensive variation inExpand
Tracing an invasion: landbridges, refugia, and the phylogeography of the Neotropical rattlesnake (Serpentes: Viperidae: Crotalus durissus)
Pleistocene fragmentation of the Amazonian rainforest has been hypothesized to be a major cause of Neotropical speciation and diversity. However, the role and even the reality of Pleistocene forestExpand
The phylogeny of cobras inferred from mitochondrial DNA sequences: evolution of venom spitting and the phylogeography of the African spitting cobras (Serpentes: Elapidae: Naja nigricollis complex).
We use phylogenetic analysis of 1333 bp of mitochondrial DNA sequence to investigate the phylogeny and historical biogeography of the cobra-like elapid snakes, with special reference to the evolutionExpand
Historical biogeography of the Western Rattlesnake (Serpentes: viperidae: Crotalus viridis), inferred from mitochondrial DNA sequence information.
We infer the phylogeography of the Western Rattlesnake (Crotalus viridis) using phylogenetic analysis of mitochondrial DNA sequences from 1345 bp of the genes for cytochrome b and NADH dehydrogenaseExpand
When continents collide: phylogeny, historical biogeography and systematics of the medically important viper genus Echis (Squamata: Serpentes: Viperidae).
We analyze the phylogeny of the medically important and taxonomically unresolved viper genus Echis using four mitochondrial gene fragments. The results show that the populations of the genus fallExpand
Snakes across the Strait: trans-Torresian phylogeographic relationships in three genera of Australasian snakes (Serpentes: Elapidae: Acanthophis, Oxyuranus, and Pseudechis).
We analyze the phylogeny of three genera of Australasian elapid snakes (Acanthophis-death adders; Oxyuranus-taipans; Pseudechis-blacksnakes), using parsimony, maximum likelihood, and BayesianExpand
Molecular clocks and geological dates: cytochrome b of Anolis extremus substantially contradicts dating of Barbados emergence
Even though molecular clocks vary in rate to some extent, they are widely used and very important in a range of evolutionary studies, not least in interpreting cause and colonization inExpand
Optimal intron analyses in the trimeresurus radiation of Asian pitvipers.
Nuclear introns are commonly used as phylogenetic markers, but a number of issues related to alignment strategies, indel treatments, and the incorporation of length-variant heterozygotes (LVHs) areExpand
Inclusion of nuclear intron sequence data helps to identify the Asian sister group of New World pitvipers.
Despite much effort towards resolving the molecular phylogenetic tree for pitvipers, some aspects remain unresolved. In particular, the sister group of the diverse New World radiation has remainedExpand
