“…Nucleotide diversity was highest in Türkiye (π= 0.0258) followed by Iran (π= 0.0233), Hungary (π= 0.0166), and Spain (π= 0.0083) (Table 1). A recent study conducted on only the Turkish populations of C. quercus revealed the presence of high genetic variation in the species particularly in the eastern/southeastern Anatolian populations (Mutun & Dinç, 2019). In this current study, the presence of high genetic diversity in each of the C. quercus populations is not unexpected since the Iberian Peninsula and the Balkans have been used as shelter areas by many taxa during the harsh environmental conditions of the last few ice ages, thus constituting the two important diversity centres for Europe (Hewitt, 2004).…”

In this study, we used DNA sequence data of a western Palearctic oak gall wasp species, Cynips quercus, showing distribution from Europe to Iran to answer the following questions: i) Do the eastern C. quercus populations have higher genetic diversity than the European populations?, ii) Are the eastern populations source for the European populations?, iii) What is the possible date of divergence between the Asian and European populations? For these purposes, we analysed 88 cytochrome b sequences representing Iran, Türkiye, Hungary, and Spain. Our analyses revealed that the highest genetic diversity was in Türkiye followed by Iran, Hungary, and Spain, respectively. Iranian samples were most divergent from the Spain and Hungary sequences. Pairwise comparisons showed that the highest gene flow was between Türkiye and Hungary, and between Türkiye and Iran, respectively. Phylogenetic analysis grouped the Turkish haplotypes with the Iranian sequences, and Spain was grouped with Hungary. Network analysis revealed that the western Turkish samples were separated from eastern sequences, and all of the eastern Turkish sequences were clustered with the Iranian samples meanwhile a western Turkish lineage provided source to Hungary and then to Spain. Times of divergence analysis estimated that the Turkish lineage split from the Iranian lineage around 4,67 million years, and Hungarian and Spanish lineages diverged from each other about 3 million years ago. Correspondingly, our analyses suggested that Anatolia played a key role as a bridge between Asian and European populations of C. quercus.

“…In the Pliocene, the wet and humid conditions changed to the colder and more arid conditions of the Pleistocene, with an impact on the landscapes as open vegetation started to spread. In the Pleistocene, Anatolia served as a refuge during the last glacial and interglacial cycles, and the AD may have acted as an environmental barrier at that time, limiting the dispersal for many taxa and promoting speciation (e.g., [62,63,[71][72][73][74][75][76][77][78][79]).…”

Molecular data for 19 specimens of Elmis syriaca syriaca and E. s. zoufali from eight countries have been analysed in order to investigate the taxonomic status and the geographical distribution of these two subspecies. The nominative subspecies was previously thought to be endemic to the Levant (Israel, Lebanon, Syria), while E. s. zoufali was regarded as being widespread from the Balkans to eastern Anatolia and Afghanistan. The results of our molecular studies using DNA barcoding and nuclear DNA data reveal that the two taxa are in fact distinct species, which separated around 2 Mya. A distinction based on the external morphological characters of 354 specimens was found to be impossible due to the pronounced variability, especially of the pronotal microsculpture, which had hitherto been used as the main distinguishing feature. The two species can only be distinguished by the aedeagal parameres and by the geographical distribution, which deviates considerably from the concept of previous authors. Elmis zoufali is distributed in Romania, the Balkan Peninsula, some Aegean Islands and in western Anatolia, while E. syriaca occurs from the Caucasus region southwards to eastern Turkey, Iran (probably also Afghanistan) and the Levant. Geographically, both species are widely separated by the so-called Anatolian Diagonal. Elmis zoufali resp. E. syriaca are recorded for the first time from Croatia, Romania, Azerbaijan, Georgia, Iran and Turkey. In addition, we examined 13 specimens tentatively identified as Elmis quadricollis (Reitter, 1887), a closely related species from Central Asia; we sequenced one specimen from China, which was revealed to be a sister to E. zoufali and E. syriaca.

“…It has long been suggested that there are two distinct Great Bustard subpopulations in western and eastern Turkey (Karakaş and Akarsu 2009), and our findings support this view. The Anatolian diagonal, which lies between the two populations, is a well-known biogeographic barrier shaping phylogeography and the distribution of various organisms (Nilson et al 1990, Gül 2013, Mutun and Dinç 2019). The diagonal is located at the eco-regional transitional zone, where there is a sharp environmental gradient (temperature seasonality, precipitation, elevation; Gür 2016).…”

Summary The Great Bustard Otis tarda is a globally threatened species with populations inhabiting the steppe zones of Turkey. In recent decades, its populations in Turkey have suffered severe declines in range and size. Although the remaining populations are in urgent need of protection, there has been no national-scale study on the species since 2009, and huge information gaps remain concerning its range, abundance, and movements in the country. Here, we combined data from five years of fieldwork together with all available sight and literature records to present up-to-date estimates of distribution and population size in Turkey, to better understand its movement patterns, to reveal its recent and historical population changes, and to assess its national extinction risk and threats. We find that the species’ breeding population has shrunk by 20–29% over the last five years, and there are only 559–780 breeding Great Bustards in Turkey distributed in two discrete subpopulations. Comparison with historical records shows that the species’ range has shrunk by at least 60% since the beginning of the 20th century. We suggest possible migratory routes within and through Turkey and that Turkey might have a higher regional importance for the species than previously thought. Illegal hunting, agricultural intensification, shift to irrigated crops, overgrazing, collision with powerlines, and disturbance are the most severe threats to the species in Turkey. Our national Red List assessment yields an Endangered categorisation. Further studies are needed to understand the metapopulation structure and movements of the species and to conserve its remaining populations in Turkey.
