  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.

  Исследовали структуру и эволюцию семейства сателлитной ДНК ящериц рода Darevskia сем. 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.

  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. chlorogaster and D. defilippii, both distributed in northern Iran. 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. chlorogaster and D. defilippii, respectively. Trained with genetically determined clades, Ecological Niche Modeling provided additional support for these cryptic species. Especially those within the D. defilippii-complex exhibit well-differentiated niches. 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. chlorogaster-complex. In conclusion, the results support four new species, which are described herein.
