We analyzed the phylogeny of the Neotropical pitvipers within the Porthidium group
(including intra-specific through inter-generic relationships) using 1.4 kb of DNA sequences�…

Aim A number of processes can lead to weak or conflicting phylogenetic signals, especially
in geographically dynamic regions where unstable landscapes and climates promote�…

Gaps in recent studies of hognosed pit vipers in the genus Porthidium have left researchers
with an incomplete estimate of the evolutionary history of this group. Mitochondrial DNA�…

Aim We derived phylogenies, phylogeographies, and population demographies for two
North American pitvipers, Agkistrodon contortrix (Linnaeus, 1766) and A. piscivorus�…

The subfamily Crotalinae (pitvipers) contains over 190 species of venomous snakes
distributed in both the Old and New World. We incorporated an extensive sampling of taxa�…

With the continued adoption of genome‐scale data in evolutionary biology comes the
challenge of adequately harnessing the information to make accurate phylogenetic�…

Aim We used inferences of phylogenetic relationships and divergence times for three
lineages of highland pitvipers to identify broad‐scale historical events that have shaped the�…

Abstract During Pleistocene, the Laurentide ice sheet rearranged and diversified biotic
distributions in eastern North America, yet had minimal physical impact in western North�…

Systematics of the snake subfamily Crotalinae (Serpentes: Viperidae) were investigated by
means of mtDNA (12S and 16S rDNA sequences); 45 species, which included all genera�…

We use published and new mitochondrial DNA sequence data to investigate the origins and
evolution of the South American pitviper fauna. South America was invaded by at least four�…
