A phylogeny and revised classification of Squamata, including 4161 species of lizards and snakes
BackgroundThe extant squamates (>9400 known species of lizards and snakes) are one of the most diverse and conspicuous radiations of terrestrial vertebrates, but no studies have attempted toExpand

Coalescent-based species delimitation in an integrative taxonomy.
The statistical rigor of species delimitation has increased dramatically over the past decade. Coalescent theory provides powerful models for population genetic inference, and is now increasinglyExpand

Phylogeny and tempo of diversification in the superradiation of spiny-rayed fishes
Spiny-rayed fishes, or acanthomorphs, comprise nearly one-third of all living vertebrates. Despite their dominant role in aquatic ecosystems, the evolutionary history and tempo of acanthomorphExpand

Phylogeny of the Colubroidea (Serpentes): new evidence from mitochondrial and nuclear genes.
The Colubroidea contains over 85% of all the extant species of snakes and is recognized as monophyletic based on morphological and molecular data. Using DNA sequences (cyt b, c-mos) from 100 speciesExpand

MITOCHONDRIAL DNA PHYLOGEOGRAPHY OF THE POLYTYPIC NORTH AMERICAN RAT SNAKE (ELAPHE OBSOLETA): A CRITIQUE OF THE SUBSPECIES CONCEPT
Abstract Subspecies have been considered artificial subdivisions of species, pattern classes, or incipient species. However, with more data and modern phylogenetic techniques, some subspecies may beExpand

The phylogeny of advanced snakes (Colubroidea), with discovery of a new subfamily and comparison of support methods for likelihood trees.
The superfamily Colubroidea (> 2500 species) includes the majority of snake species and is one of the most conspicuous and well-known radiations of terrestrial vertebrates. However, many aspects ofExpand

Early origin of viviparity and multiple reversions to oviparity in squamate reptiles.
Viviparity has putatively evolved 115 times in squamates (lizards and snakes), out of only ~ 140 origins in vertebrates, and is apparently related to colder climates and other factors such as bodyExpand

How and when did Old World ratsnakes disperse into the New World?
To examine Holarctic snake dispersal, we inferred a phylogenetic tree from four mtDNA genes and one scnDNA gene for most species of the Old World (OW) and New World (NW) colubrid group known asExpand

Neogene diversification and taxonomic stability in the snake tribe Lampropeltini (Serpentes: Colubridae).
The impact of climate change during the Pleistocene on organisms living in temperate areas of the world has been documented for more than fifty years (Rand, 1948). A major impact of PleistoceneExpand

EXTINCTION, ECOLOGICAL OPPORTUNITY, AND THE ORIGINS OF GLOBAL SNAKE DIVERSITY
Snake diversity varies by at least two orders of magnitude among extant lineages, with numerous groups containing only one or two species, and several young clades exhibiting exceptional richnessExpand
