Green-bellied Lizard English. Lectotype: BMNH Rabino, designated by Ahmadzadeh et al. Measurements and scale counts of this specimen are in accordance with the one illustrated in the original description. The remaining syntypes are consequently designated paralectotypes. Woosnam BMNH Boulenger, G. Ciobanu, D. The structure and evolution of a satellite DNA family was examined in lizards from the genus Darevskia family Lacertidae.

Comparison of tandem units of repeated DNA satDNA , CLsat, in all species from the genus Darevskiahas shown that their variability is largely explained by single-nucleotide substitutions, which form about 50 diagnostic positions underlying classification of the family into three subfamilies.

The presence of highly conserved regions in all monomers and some features of their organization show that satellites of all Darevskia species belong to one satDNA family. The organization of unit sequences of satellites CLsat and Agi also detected by us in another lizard genus, Lacerta s.

Similarity that was found between these satellites suggests their relatedness and common origin. A possible pathway of evolution of these two satDNA families is proposed. The distribution and content of CLsat repeat subfamilies in all species of the genus was examined by Southern hybridization.

Based on these results as well as on zoogeographic views on the taxonomy and phylogeny of the Darevskia species, hypotheses on the evolution of molecular-genetic relationships within this genus are advanced.

Ahmadzadeh, F. While traditionally species recognition has been based solely on morphological differences either typological or quantitative, several newly developed methods can be used for a more objective and integrative approach on species delimitation.

This may be especially relevant when dealing with cryptic species or species complexes, where high overallresemblance between species is coupled with comparatively high morphological variation within populations. Rock lizards, genus Darevskia, are such an example, as many of its members offer few diagnostic morphological features. Herein, we use a combination of genetic, morphological and ecological criteria to delimit cryptic species within two species complexes, D.

Our analyses are based on molecular information from two nuclear and two mitochondrial genes, morphological data 15 morphometric, 16 meristic and four categorical characters and eleven newly calculated spatial environmental predictors. The phylogeny inferred for Darevskia confirmed monophyly of each species complex, with each of them comprising several highly divergent clades, especially when compared to other congeners.

We identified seven candidate species within each complex, of which three and four species were supported by Bayesian species delimitation within D.

Trained with genetically determined clades, Ecological Niche Modeling provided additional support for these cryptic species. Especially those within the D. Due to overall morphological resemblance, in a first approach PCA with mixed variables only showed the separation between the two complexes. However, MANCOVA and subsequent Discriminant Analysis performed separately for both complexes allowed for distinction of the species when sample size was large enough, namely within the D.

In conclusion, the results support four new species, which are described herein. Azerbaijan , Iran. Darevskia chlorogaster: 41 references. AG magazine in print. Online magazine pdf.

English-German Dictionary

Darevskia is a genus of wall lizards of the family Lacertidae living in the Caucasus, Iran and Turkey in forest and grassy habitats with numerous rock outcrops. Among rock lizards, 7 parthenogenetic species are known. These are small lizards with a body length of 50—85 mm and with about two times longer tail. The body is usually flattened, the head is pointed in shape and in most species flattened in a vertical plane, which allows lizards to hide in narrow crevices between stones and rocks. Rock lizards have relatively long legs with special calluses on the inner surfaces of the paws and sharp claws, thanks to which they quickly move along the vertical rough surfaces of rocks and stones.
