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 diversity and relatedness determined by short tandem repeat genotyping of 81 individuals from the four largest colonies. Our results demonstrated no significant genetic structuring, suggesting a single panmictic metapopulation connected by frequent dispersal. Furthermore, we show that the study population has retained moderate levels of genetic diversity, despite passing through a recent demographic bottleneck. We estimated the effective population size to be 112 individuals (95% confidence interval 74-201). Our results imply that the observed lack of increase in population size since the 1990s has not been caused by lowered fitness due to genetic inbreeding but rather by increased mortality via demographic processes. In the short term, we suggest that conservation efforts should treat the Turkish subpopulations as a single management unit and aim to increase population size through effective protection, especially during the breeding season.


Genetic structure and phylogenetic relations of cinereous vulture (aegypius monachus) populations in Turkey
Çakmak, Emel; Bilgin, Cemal Can; Department of Biology (2018)
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 mitoc...
Genetic and morphologic diversity of Pseudophoxinus (Cyprinidae): implication for conservation in Anatolia
TELLİ, MURAT; Aykut, Kence (Springer Science and Business Media LLC, 2015-01-01)
Pseudophoxinus a freshwater fish genus shows remarkable diversification with high number of endemic species in Anatolia. Most of the species of the genus are categorized as endangered for conservation in IUCN Red List due to water abstraction and habitat destruction. The aim of the study is to investigate genetic and morphological structure of Pseudophoxinus populations using allozyme, microsatellite markers and geometric morphometrics (eight landmarks). Sample collection was performed from eight localities...
Exceptional maternal lineage diversity in brown bears (Ursus arctos) from Turkey

The genetic diversity and phylogeography of maternal lineages in Ursus arctos Linnaeus, 1758 (the brown bear) have been studied extensively over the last two decades; however, sampling has largely been limited to the northern Holarctic, and was possibly biased towards lineages that recolonized the vast expanses of the north as the Last Glacial Maximum (LGM) ended. Here we report the genetic diversity and phylogeography of U.arctos from Turkey based on 35 non-invasive samples, including five from captive ind...
Genetic relationships among perennial and annual Cicer species growing in Turkey as revealed by allozymes
Sudupak, MA; Kence, Aykut (Springer Science and Business Media LLC, 2004-05-01)
Allozyme polymorphisms were used to assess genetic variation and relationships among ten Cicer species ( annuals and perennials) growing in Turkey. Using seven enzyme systems, 12 putative scorable loci were detected and surveyed for polymorphism in an accession collection including wild and cultivated forms. Variation was generally low within accessions and species, but common between species. Cluster analysis based on the pairwise genetic distance coefficients (Nei 1978) among accessions and species using ...
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...
