Genetic structure and phylogenetic relations of cinereous vulture (aegypius monachus) populations in Turkey

Çakmak, Emel
Throughout the world, vulture populations have suffered threatening declines in numbers in recent years. The Cinereous Vulture (Aegypius monachus) is a highly philopatric scavenger that ranges across southern Europe and the central Asian plateau. Turkey holds the second most numerous population in the Western Palearctic but there has been no research on the genetic structure of this particular population. In the present study, we describe the current genetic status of the Turkish population using both mitochondrial cytochrome b sequences and nuclear microsatellite markers. Although, mitochondrial (mt) DNA revealed extremely low genetic variability (haplotype diversity), nuclear diversity based on allelic richness and expected heterozygosity demonstrated moderate levels of genetic variation. Phylogenetic analyses indicated that the Turkish lineage, together with the Caucasus population, occupies an intermediate position between European (Balkan and Iberian) and Central Asian (Mongolian) lineages. We could not detect any significant differentiation between the four sub-populations (Çatacık, Tandır, Türkmenbaba and Köroğlu), which suggests that the sampled 81 individuals originated from a single large, panmictic population. Additionally, we observed evidence of a recent bottleneck in the Turkish populations and a low effective population size of 112 (95% CI 74–201). A population viability analysis using VORTEX revealed predicted population dynamics. These findings suggest that conservation strategies should be developed for treating Turkish populations as a single management unit.

Vulture populations worldwide have suffered precipitous declines in recent decades. The Cinereous Vulture Aegypius monachus, a highly philopatric scavenger distributed across southern Europe and the central Asian plateau, is threatened in many parts of its range. Turkey holds the second largest population of this species in the Western Palaearctic, but there has been no research on its genetic structure and the possible implications of this structure for the future of the species. Here we report nuclear div...
Extremely Low Mitochondrial DNA Diversity in a near Threatened Species, the Cinereous Vulture Aegypius monachus in Turkey
Çakmak, Emel; Akin Pekçen, Çiǧdem; Kirazli, Cihangir; Yamaç, Elif; Bilgin, Cemal Can (2019-04-01)
The Cinereous Vulture Aegypius monachus is a near threatened raptor that occurs in isolated populations across its range. The only comprehensive genetic study performed so far excluded samples from Turkey, although this area forms a significant part of the species' range. In this study, we used 311 bp long sequences of the mitochondrial cytochrome b gene from 58 Turkish individuals to assess genetic diversity and phylogeny, and to determine if any signals for population expansion exist. Our phylogenetic ana...

The dispersal of pelagic larvae in marine environments is one mechanism of connecting marine populations across large distances and structuring their population success and persistence. It is mostlythe planktonic stages of marine species that are affected by such large-scale transport during the times when directional swimming is not yet developed. In the Southern Ocean, Antarctic krill is a key component of the marine food web playing a fundamental role in the transfer of energy between the lower and the u...
Genetic diversity of gazelles (gazella marica and gazella gazella) in Southeast Turkey: with a special emphasis on ongoing conservation studies of gazella marica in Turkey
Saatoğlu, Dilan; Togan, İnci Zehra; Department of Biology (2015)
The present study was conducted to confirm the recently suggested taxonomic status of gazelles in Turkey and also to investigate genetic diversity that exists between and within populations of Gazella marica (One from Kızılkuyu State Farm, Şanlıurfa, n=48; one from Erikçe State Farm, Gaziantep, n=25) and Gazella gazella (population from Kırıkhan County, Hatay, n=4). In the frame of the study, partial mtDNA cyt-b sequence (amplified by the primers: L14724, H15149), 17 microsatellite loci (RT1, ETH10, OARFCB3...
Genetic relationships among perennial and annual Cicer species growing in Turkey assessed by AFLP fingerprinting
Sudupak, MA; Akkaya, Mahinur; Kence, A (Springer Science and Business Media LLC, 2004-03-01)
AFLP markers were used to assess genetic relationships among Cicer species with distribution in Turkey. Genetic distances were computed among 47 Cicer accessions representing four perennial and six annual species including chickpea, using 306 positions on AFLP gels. AFLP-based grouping of species revealed two clusters, one of which includes three perennial species, Cicer montbretii, Cicer isauricum and Cicer anatolicum, while the other cluster consists of two subclusters, one including one perennial, Cicer ...
