“…For this reason, a 'refugia-withinrefugia' pattern during the Pleistocene climatic oscillations has also been proposed for Anatolia, with several studies describing secondary contacts and hybridization events (Fritz et al, 2009;Guicking, Joger, & Wink, 2009;Kindler et al, 2013;Stöck et al, 2012;Vamberger et al, 2013). This high level of genetic diversity in Anatolia has also reported in several other organisms (Dubey et al, 2007;Korkmaz et al, 2014;Rokas et al, 2003) and reptile groups (Bellati et al, 2015;Kornilios et al, 2012Kornilios et al, , 2018Kornilios et al, , 2020Rato et al, 2021;Sindaco et al, 2013;Tamar et al, 2016).…”

The smooth snake Coronella austriaca (Laurenti, 1768) is distributed across the western Palearctic throughout north-central, southern Europe and western Asia.So far, only few phylogenetic studies, based on mitochondrial DNA, have been carried out on this species focusing mainly on the Iberian Peninsula and northern Europe, leaving unstudied some of important areas of its distribution. This study aims to cover this gap and to explore the phylogenetic relationships between the populations of in the Eastern Mediterranean and to detect possible historical refugia. With this objective, total genomic DNA was extracted from samples originated from the Balkans, Anatolia and a large part of Europe. Two mitochondrial (cyt b, 16S) and six nuclear (BDNF, NKTR, RAG1, RAG2, MC1R and PRLR) markers were combined for phylogenetic and chronophylogenetic analyses.The different analyses confirmed previous phylogeographic hypothesis showing the presence of several well-supported clades distributed in Anatolia, Central Europe, Eastern Europe, Western Europe, the Balkans and the Iberian Peninsula and cryptic diversity within Anatolia and the Balkans. Moreover, dating analysis

“…In Darevskia, differences between 3.8-4.8% in cyt b correspond to species level detected for example in D. bithyni ca (Méhely, 1909). On the other hand, the taxo nomic position of this species belonging to the D. rudis complex is supported by differences in biparental mark ers and ecological niches (Rato et al 2020). Our data, however, allows the hypothesis that the Central lineage may represent a distinct taxon, most likely of the sub species rank.…”

“…Ecological niches for the closely related species are expected to be more similar compared with deeply diverged species, generally following a pattern of niche conservatism (Wiens and Graham 2005). Evidence of both niche conservatism and niche divergence has been reported in other representatives of the Darevskia genus (Ahmadzadeh et al 2013;Kurnaz et al 2019;Kurnaz and Yousefkhani 2020;Rato et al 2020). As shown in pre vious work, closely related species tend to occupy sim ilar ecological niches, while divergence can occur when significant shifts in habitat use are followed by morpho logical changes of functional traits (Schulte et al 2004;Collar et al 2010).…”

The Lindholm rock lizard, Darevskia lindholmi, is the only member of the genus Darevskia whose range is restricted solely to Europe, representing a local endemism found only in the Crimean Mountains. In our study, we investigated the cytochrome b gene (mtDNA) of 101 D. lindholmi sequences from 65 Crimean localities, representing its entire range. We found that D. lindholmi is highly genetically structured, and its range is divided into populations belonging to three mitochondrial lineages. The Lindholm rock lizard populations inhabiting the middle part of the Crimean Mountains (further referred to as the Central lineage) are sharply differentiated from the other two lineages (the Common and the Southwestern lineages), which are present in most of the species range. The genetic distance between the Central lineage and the other two taken together is 4.6%, according to our results, suggesting that the divergence occurred during the Early Pleistocene. The narrowly distributed Southwestern lineage and the widespread Common lineage, on the other hand, are differentiated by 1%. Field observations on the representatives of the main evolutionary groups show that their ecology is also different: the Central lineage is a mesophilic and cold-resistant form, while the other two closely related lineages are more xerophilic and thermophilic. Results of the potential ranges modeling and ecological niche analysis confirm that the genetic lineages occupy different niches of the Crimea. Furthermore, the area of inhabitation of the Central lineage splits the western and eastern parts of the Common lineage range, while the Southwestern lineage is restricted along the coast of the southwestern coast of the peninsula. The long-term co-existence of deeply divergent sister mitochondrial lineages in a relatively small (circa 7,000 km2) isolated mountain system serves as a mesocosm for understanding the speciation process. Our data suggest that the Central lineage warrants further taxonomic investigation.

Parthenogenesis in Darevskia lizards: A rare outcome of common hybridization, not a common outcome of rare hybridization

Hybridization is a common evolutionary process with multiple possible outcomes. In vertebrates, interspecific hybridization has repeatedly generated parthenogenetic hybrid species. However, it is unknown whether the generation of parthenogenetic hybrids is a rare outcome of frequent hybridization between sexual species within a genus or the typical outcome of rare hybridization events. Darevskia is a genus of rock lizards with both hybrid parthenogenetic and sexual species. Using capture sequencing, we estimate phylogenetic relationships and gene flow among the sexual species, to determine how introgressive hybridization relates to the origins of parthenogenetic hybrids. We find evidence for widespread hybridization with gene flow, both between recently diverged species and deep branches. Surprisingly, we find no signal of gene flow between parental species of the parthenogenetic hybrids, suggesting that the parental pairs were either reproductively or geographically isolated early in their divergence. The generation of parthenogenetic hybrids in Darevskia is, then, a rare outcome of the total occurrence of hybridization within the genus, but the typical outcome when specific species pairs hybridize. Our results question the conventional view that parthenogenetic lineages are generated by hybridization in a window of divergence. Instead, they suggest that some lineages possess specific properties that underpin successful parthenogenetic reproduction.
