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

A multivariate analysis of the fringe-toed lizards of the Acanthodactylus scutellatus group (Squamata: Lacertidae): systematic and biogeographical implications
The taxonomy of the fringe-toed lizards of the Acanthodactylus scutellatus group has long been unstable and no consensus exists on the systematic status of its various forms. A multivariate analysisExpand

A hybrid phylogenetic-phylogenomic approach for species tree estimation in African Agama lizards with applications to biogeography, character evolution, and diversification.
Africa is renowned for its biodiversity and endemicity, yet little is known about the factors shaping them across the continent. African Agama lizards (45 species) have a pan-continentalExpand

What, if anything, is a 'typical' viper? Biological attributes of basal viperid snakes (genus Causus Wagler, 1830)
For many major phylogenetic radiations of organisms, the available ecological knowledge is disproportionately derived from a small minority of taxa, and sometimes from organisms that are highlyExpand

Comparative Data on Epiphyseal Development in the Family Varanidae
Abstract Radiographic and histologic examination of long bone epiphyses in 25 species of Varanoidea (including one Heloderma species) reveals a qualitative difference in epiphyseal developmentExpand

Terrestrial locomotion in sea snakes: the effects of sex and species on cliff-climbing ability in sea kraits (Serpentes, Elapidae, Laticauda)
Ecomorphological theory predicts a match between an organism's environment and its locomotor abilities, such that animals function most effectively under the conditions they experience in nature.Expand

Molecular data from contemporary and historical collections reveal a complex story of cryptic diversification in the Varanus (Polydaedalus) niloticus Species Group.
Previous studies of color pattern, tongue pigmentation, and scale counts have been used to distinguish two species of semiaquatic varanids in Africa, but these findings have yet to be tested withExpand

Comments on the Identities of Certain Tantilla ( Squamata : Colubridae ) from Guatemala , with the Descriptions of Two New Species
An examination of types representing Guatemalan species of Tantilla of the T. taeniata group reveals that current concepts for several species are incorrect and that several species remainExpand

Two new species of the genus Sitana Cuvier, 1829 (Reptilia: Agamidae) from Sri Lanka, including a taxonomic revision of the Indian Sitana species.
The genus Sitana was described by Cuvier (1829) on the basis of a single species, S. ponticeriana. The secondly described, Sitana minor Günther, 1864, is identical to S. ponticeriana Cuvier, 1829,Expand

Insights into chameleons of the genus Trioceros (Squamata: Chamaeleonidae) in Cameroon, with the resurrection of Chamaeleon serratus Mertens, 1922
Relationships among chameleons of the genus Trioceros in Cameroon are reviewed on a molecular basis us- ing mitochondrial genes and by morphology. Trioceros oweni is placed basal to two distinctExpand
