The chukar (Alectoris chukar, Galliformes) is a species hunted throughout its native range from the East Mediterranean to Manchuria and in the USA, which hosts the world's largest introduced population. This study aims to investigate the genetic structure of Mediterranean chukar populations to aid management decisions. We genotyped 143 specimens at two regions of the mitochondrial DNA (mtDNA: cytochrome b, control region) and eight loci of the microsatellite DNA. Samples were collected in northern (Limnos, Lesvos, Chios) and southern (Crete) Aegean islands (Greece) and Cyprus. We also carried out mtDNA-based comparison with chukars (n = 124) from Asia (16 countries) and the USA (five states). We propose six management units for Mediterranean populations. Given their genetic integrity, Limnos and Cyprus, which host different subspecies, proved to be of primary conservation interest. We found exotic A. chukar mtDNA lineages in Lesvos, Chios and Crete and produced definitive genetic evidence for the Asian origin of the US chukars.
石鸡(Alectoris chukar,鸡形目)是一种在其原生范围内被猎杀的物种,其原生范围从东地中海到满洲,在美国也有分布,美国拥有世界上最大的引入种群。本研究旨在调查地中海石鸡种群的遗传结构,以辅助管理决策。我们对143个样本的线粒体DNA(mtDNA:细胞色素b、控制区)的两个区域以及微卫星DNA的八个位点进行了基因分型。样本采集于爱琴海北部(利姆诺斯岛、莱斯博斯岛、希俄斯岛)和南部(克里特岛)的岛屿(希腊)以及塞浦路斯。我们还对来自亚洲(16个国家)和美国(五个州)的石鸡(n = 124)进行了基于mtDNA的比较。我们为地中海种群提出了六个管理单元。鉴于其遗传完整性,拥有不同亚种的利姆诺斯岛和塞浦路斯被证明具有首要的保护意义。我们在莱斯博斯岛、希俄斯岛和克里特岛发现了外来的石鸡mtDNA谱系,并为美国石鸡的亚洲起源提供了确凿的遗传证据。
