The Oriental large-bodied crested dragons of the genus Gonocephalus are known to include two distinct karyomorphs. To evaluate their phylogenetic significances, we conducted phylogenetic analyses of the genus together with other agamid genera on the basis of 862 base positions of mitochondrial 12S and 16S rRNA genes. Results suggested the presence of two distinct lineages within Gonocephalus, o...

We used pitfall trapping to investigate the effects of elevation, plant density and soil structure on species diversity and the impact of these habitat factors on lizard habitat selectivity in the Qom Province in the Central Plateau of Iran. From a total of 12 1-ha plots, we captured 363 individuals of 15 species of lizards (six species of Lacertidae, five species of Agamidae, two species of Ge...

Conspicuous colouration can evolve as a primary defence mechanism that advertises unprofitability and discourages predatory attacks. Geographic overlap is a primary determinant of whether individual predators encounter, and thus learn to avoid, such aposematic prey. We experimentally tested whether the conspicuous colouration displayed by Old World pachyrhynchid weevils (Pachyrhynchus tobafoliu...

We describe a new species of the agamid genus Calotes Cuvier, 1817 from southern Vietnam, which is most similar to Calotes mystaceus Duméril & Bibron, 1837, but can be distinguished from the latter and its other congeners by genetic and morphological differences. We discuss the current distribution of the new species and its sister species C. mystaceus in Mainland Southeast Asia.

abstract squamata or scaled reptiles are the largest order of new reptiles including lizards, snakes and amphisbaenia. they have formed 95 precent of new reptiles. our goal is lizard biodiversity of torbat-e heydaryeh in razavi khorasan province. the study of lizards biodiversity of torbat-e heydaryeh in razavi khorasan province was carried out in 2012 until 2013. in this research 132 specimens...

The present study describes by means of immunohistochemistry the comparative distribution of glial fibrillary acidic protein (GFAP)-positive cells in the forebrain and midbrain of three species of lizards: Eumeces algeriensis, Scincoidae; Agama impalearis, Agamidae; Tarentola mauritanica, Gekkonidae. In the species studied, the different types and proportions of glial cells expressing GFAP show...

The expression in females of ornaments thought to be the target of sexual selection in males is a long-standing puzzle. Two main hypotheses are proposed to account for the existence of conspicuous ornaments in both sexes (mutual ornamentation): genetic correlation between the sexes and sexual selection on females as well as males. We examined the pattern of ornament gains and losses in 240 spec...

Despite exhibiting considerable interspecific variation in body mass, flying lizards of the genus Draco are isometric in their area-mass scaling relationships and exhibit no significant compensatory variation in wing aspect ratio. Thus, larger species are expected to be relatively poor gliders, in lieu of behavioral or physiological compensation, when compared with smaller congeners. Here we te...

Two new species of pterygosomatid mites parasitizing lizards of the family Agamidae are described: Pterygosoma aqabensis sp. nov. from Pseudotrapelus aqabensis Melnikov et al. and Pterygosoma dhofarensis sp.nov. from Pseudotrapelus dhofarensis Melnikov and Pierson both from Arabian Peninsula. Pterygosoma aqabensis sp. nov. is most closely related to P. dhofarensis sp. nov. but differs by the pr...
