Mabuya vitatta (Olivier) (Scincidae) and Agama stellio (L.) (Agamidae) were infected with Hemolivia mariae Smallridge et Paperna, 1997 by ingestion of tick viscera from Amblyomma limbatum Neumann, fed as nymphs on naturally infected Australian sleepy lizards, Tiliqua rugosa Gray. The unnatural infection apparently interfered with the developmental schedule of the parasites. Transmission electro...

The characteristics of the hemipenis Scincidae and Agamidae New Guinea are veryrarely studied, although they very easy to do. Morphological andhemipenis size between these two families different. Some have a cylindrical that is not lobed lobed, some even variety structures withdistinctive ornaments. Tail length can affect hemipenis. This study aims describe Guinea. species Lamprolepis smaragdin...

The habitat destruction and land-use changes caused the decline of animal composition in many tropical regions. Here, we study diversity herpetofauna lowland areas Sumatera Barat, a midwestern province island, using visual encounter survey method. surveyed included rubber plantations, streams, paddy fields, peat swamps. We observed 338 individuals representing 44 species from 14 families with a...

Three new species of pterygosomatid mites Pterygosoma engai sp. nov. P. indare sp. nov. and P olape sp. nov. (Acari: Pterygosomatidae) are described from the agamid lizard Agama sankaranica (Sauria: Agamidae) from Kenya. P. engai sp. nov. is similar to P annectans circularis Jack, 1962 but in the new species, the anterior paddle-shaped setae with spicules on the apical margin of the idiosomal d...

Habitat use may lead to variation in diversity among evolutionary lineages because habitats differ in the variety of ways they allow for species to make a living. Here, we show that structural habitats contribute to differential diversification of limb and body form in dragon lizards (Agamidae). Based on phylogenetic analysis and ancestral state reconstructions for 90 species, we find that mult...

Iguanian lizards form a diverse clade whose members have been the focus of many comparative studies of ecology, behavior, and evolution. Despite the importance of phylogeny to such studies, interrelationships among many iguanian clades remain uncertain. Within the Old World clade Acrodonta, Agamidae is sometimes found to be paraphyletic with respect to Chamaeleonidae, and recent molecular studi...

The usage of invasive tagging methods to assess lizard populations has often been criticised, due to the potential negative effects of marking, which possibly cause increased mortality or altered behaviour. The development of safe, less invasive techniques is essential for improved ecological study and conservation of lizard populations. In this study, we describe a photographic capture-recaptu...
