External morphology and osteology of Darevskia rudis (Bedriaga, 1886), with a taxonomic revision of the Pontic and Small-Caucasus populations (Squamata: Lacertidae).

چکیده
A broad sample of Darevskia rudis from the main part of its range was reviewed with regard to external morphology (discriminant, UPGMA, MST and ANOVA analyses) and osteology. Darevskia bithynica is raised to species rank, with two subspecies: D. b. bithynica and D. b. tristis. The other subspecies are fairly similar (D. r. rudis being the most different). Two singular populations are described as subspecies: D. r. mirabilis ssp. nov. from Kaçkar Mountains, geographically adjoins the otherwise different D. r. bischoffi and D. r. bolkardaghica ssp. nov., which is geographically isolated but that seems to be very closely related to D. r. obscura.

Molecular evolution of satellite DNA repeats and speciation of lizards of the genus Darevskia (Sauria: Lacertidae).
Satellite DNA repeats were studied in Caucasian populations of 18 rock lizard species of the genus Darevskia. Four subfamilies (Caucasian Lacerta satellites (CLsat)I-IV) were identified, which shared 70%-75% sequence similarity. The distribution of CLsat subfamilies among the species was studied. All the species could be divided into at least 3 clades, depending on the content of CLsat subfamil...
متن کاملOff the scale: a new species of fish-scale gecko (Squamata: Gekkonidae: Geckolepis) with exceptionally large scales
The gecko genus Geckolepis, endemic to Madagascar and the Comoro archipelago, is taxonomically challenging. One reason is its members ability to autotomize a large portion of their scales when grasped or touched, most likely to escape predation. Based on an integrative taxonomic approach including external morphology, morphometrics, genetics, pholidosis, and osteology, we here describe the firs...

Introduction: Traditional teaching methods cannot keep up with the new knowledge in medical students anymore. There are several challenges between traditional and new teaching methods in different courses .This study has tried to compare the effects of two teaching approaches on education of osteology( lecture VS work in small groups). Methods: In a quasi experimental study, 54 medical stude...
متن کاملMorphology of the Podarcis wall lizards (Squamata: Lacertidae) from the Iberian Peninsula and North Africa: patterns of variation in a putative cryptic species complex
Cryptic species complexes represent groups that have been classified as a single species, because of the difficulty in distinguishing its members morphologically. Morphological investigation following the discovery of cryptic diversity is crucial for describing and conserving biodiversity. Here we present a detailed account of morphological variation in a group of Iberian and North African Poda...

Species diversity in skinks in the genus Brachymeles recently has undergone a state of flux, with numerous taxonomic discoveries over the past few years. Newly available, robust data sets from morphological data and molecular sequences have revealed that taxonomic diversity within this unique group of lizards is substantially underestimated. In this third recent monographic revision of a major ...
