Cytogenetic studies on Gonatodes (Reptilia, Squamata, Sphaerodactylidae).
Mitotic and meiotic chromosomes of 5 species of the reptile genus Gonatodes are described by means of conventional staining, banding analyses and in situ hybridization using a synthetic telomeric DNA probe. The amount, location and fluorochrome affinities of constitutive heterochromatin, the number and positions of nucleolus organizer regions, and the patterns of telomeric DNA sequences were de...
متن کاملThermal physiology of Amazonian lizards (Reptilia: Squamata)
We summarize thermal-biology data of 69 species of Amazonian lizards, including mode of thermoregulation and field-active body temperatures (Tb). We also provide new data on preferred temperatures (Tpref), voluntary and thermal-tolerance ranges, and thermal-performance curves (TPC's) for 27 species from nine sites in the Brazilian Amazonia. We tested for phylogenetic signal and pairwise correla...
متن کاملNeaves’ Whiptail Lizard: the First Known Tetraploid Parthenogenetic Tetrapod (reptilia: Squamata: Teiidae)
The first known tetraploid amniote that reproduces through parthenogenetic cloning by individual females is named and described. The species originated through hybridization between Aspidoscelis exsanguis (triploid parthenogen) 3 Aspidoscelis inornata (diploid bisexual or gonochoristic species) in the laboratory. We compared multivariate morphological variation between two lineages that arose f...
متن کاملReproductive Biology of Agkistrodon Piscivorus Lacépède (squamata, Serpentes, Viperidae, Crotalinae)
Aspects of the reproductive biology of male and female Agkistrodon piscivorus are described using histological techniques, reviewed, and compared with historical data on A. piscivorus. These include anatomical description at the macro and microscopic levels, and correlation of the male and female urogenital cycles to the reproductive life history of A. piscivorus. New anatomical descriptions an...
متن کاملThe high-level classification of skinks (Reptilia, Squamata, Scincomorpha).
Skinks are usually grouped in a single family, Scincidae (1,579 species) representing one-quarter of all lizard species. Other large lizard families, such as Gekkonidae (s.l.) and Iguanidae (s.l.), have been partitioned into multiple families in recent years, based mainly on evidence from molecular phylogenies. Subfamilies and informal suprageneric groups have been used for skinks, defined by m...
