Taxonomic notes:
|
| With the introduction of the new subspecies Darevskia raddei chaldoranensis, the intermediate form, from the north-east of Turkey and the north-west of Iran, between Darevskia raddei raddei and Darevskia raddei vanensis (EISELT et al., 1993), might have been described. Also the Ararat population (PANNER, 2005; 2010) might be part of this newly described subspecies. Additional research is necessary to determine the actual distribution of all subspecies. |

(2003) - Molecular Evolution of Satellite DNA CLsat in Lizards from the Genus Darevskia (Sauria: Lacertidae): Correlation with Species Diversity. - Russian Journal of Genetics, Moscow, 39 (11): 1292-1305. × 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. Maximum differences between the subfamilies reached 25%. At this level of tandem unit divergence in the subfamilies, no cross-hybridization between them was observed (at 65°C). The individual variability within one subfamily within the species was on average 5% while the variability between species consensuses within a subfamily was 10%. 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 Agi160 also detected by us in another lizard genus, Lacerta s. str. was compared. 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. Seven species had mainly CLsatI (83 to 96%); three species, approximately equal amounts of CLsatI and CLsatIII (the admixture of CLsatII was 2–5%); and five species, a combination of all three subfamilies in highly varying proportions. 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.

Lac-ertidae. При сравнительном анализе последовательностей мономеров тандемных повторов ДНК (сатДНК) - CLsat - всех видов ящериц р. Darevskia показано, что вариабельность повторов обусловлена главным образом однонуклеотидными заменами, которые образуют около 50 диагностических позиций, на основании которых выделены три подсемейства повторов. Максимальные значения различий между подсемействами достигают 25%. При такой степени дивергенции мономеров трех подсемейств перекрестной гибридизации (при 65°С) между ними не наблюдается. Индивидуальная вариабельность мономеров одного подсемейства внутри вида в среднем составляет 5%, а вариабельность между видовыми консенсусами внутри подсемейства - 10%. Наличие высококонсервативных областей во всех мономерах и ряд особенностей их организации позволяют рассматривать сателлиты всех видов р. Darevskia как единое семейство сатДНК. Приведено сравнение организации последовательности мономеров сателлита CLsat и обнаруженного нами Agi160 из другого рода ящериц -Lacerta s. str. Выявлено сходство, свидетельствующее о родстве этих сателлитов и об их общем происхождении, предложен вероятный путь эволюции этих двух семейств сатДНК. Методом Саузерн-гибридизации изучено распространение и содержание подсемейств повторов CLsat во всех видах рода. Семь видов содержат в основном CLsatl (от 83 до 96%), три вида - примерно равные количества CLsatl и CLsatIII (примесь CLsatII составляет 2-5%), а пять видов - сумму всех трех подсемейств в сильно отличающихся соотношениях. На основе этих данных, в совокупности с зоогеографически-ми представлениями о родстве видов р. Darevskia, предложены гипотезы эволюции молекулярно-генетического родства видов этого рода.

The parthenogenetic species originated via directional hybridogenesis, with only some of the sexual species known to serve as parentals. However, it remains unclear when and where these events happened and how many parental lineages were involved. A multilocus phylogeographic analysis was performed on the parthenogens D. unisexualis, D. bendimahiensis and D. uzzeli, and their putative maternal species D. raddei. Results show the parthenogenetic species all have relatively recent origins, approximately 200–70 kyr ago, and at least three hybridization events were involved in their formation. Ecological niche models identify the region where hybridization events leading to the formation of D. unisexualis took place, namely in the northeast of the current distribution. Models also suggest that the sexual D. raddei might have undergone a habitat shift between the Last Interglacial and the Last Glacial Maximum.
