In this review, we describe the history of amniote sex determination as a classic example of Darwinian evolution. We suggest that evolutionary changes in sex determination provide a foundation for understanding important aspects of chromosome and genome organization that otherwise appear haphazard in their origins and contents. Species with genotypic sex determination often possess heteromorphi...

Three sympatric species of Ameiva in Costa Rica (A. quadrilineata, A. festiva, and A. leptophrys) were found in distinct habitats with respect to vegetation cover, ground insolation, environmental temperatures, surface litter, and activity periods. Ameiva quadrilineata commonly forages in an area of open, low vegetation cover adjacent to bare soil. Its habitat is sunnier and warmer than those o...

A new species of the genus Hemiphyllodactylus is described from Luang Prabang Province, northern Laos. Hemiphyllodactylus kiziriani sp. nov. is distinguished from the remaining congeners by morphology, coloration, and a significant genetic divergence of greater than 20% (ND2 gene). The new species from Laos is characterized by the following features: SVL of adult males 35.1-40.1 mm, of adult fe...

The name “Cetartiodactyla” was proposed in 1997 to reflect the molecular data that suggested Cetacea is closely related Artiodactyla. Since then, taxon has spread popularity, even outside scientific literature. However, implications of are confusing, because and Artiodactyla not sister-taxa. Instead, evidence clearly shows cetaceans a group embedded within Artiodactyla, sister-taxon equal rank....

This study presents the molecular phylogenetic relationships among Lytorhynchus diadema (Duméril, Bibron & Duméril, 1854) populations in Saudi Arabia relative to from Africa and Asia. analysis was based on mitochondrial 16S 12S rRNA partial gene fragments using Neighbor-joining, Maximum Parsimony, Bayesian methods. The results strongly support monophyly of two concatenated genes separat...

Over the last two decades my colleagues and I have assembled literature on a good percentage of most coccidians (Conoidasida) known, to date, parasitise: Amphibia, four major lineages Reptilia (Amphisbaenia, Chelonia, Crocodylia, Serpentes), seven orders in Mammalia (Carnivora, Chiroptera, Lagomorpha, Insectivora, Marsupialia, Primates, Scandentia). These vertebrates, combined, comprise about 1...
