The Arabian tahr (Arabitragus jayakari) occurs only in the mountains of northern Oman and the United Arab Emirates. The species is classified as Endangered due to its small declining population. In this study, we combined genetic and landscape ecology techniques in order to inform landscape scale conservation and genetic management of Arabian tahr. Using 540 base pairs of mitochondrial control region in a dataset of 53 samples, we found eight haplotypes, which fell into two haplogroups. Population genetic analysis using a panel of 14 microsatellite loci also showed a weak, but significant division. Analyses of landscape connectivity supported the genetic results showing poor connectivity between populations in the far south of the study area and those in the north. The most likely location of corridors connecting Arabian tahr populations were identified. Many corridors between tahr populations are impeded by multi-lane highways and restoration of these connections is required to maintain population viability of Arabian tahr. Owing to limited genetic samples outside of Wadi Sareen, further sampling is needed to elucidate both mtDNA and the nuclear structure of Arabian tahr more fully. Our study provides a toolkit that may be used for future genetic and connectivity monitoring of the Arabian tahr population.

濒危阿拉伯塔尔河种群结构、遗传多样性和景观连通性的首次评估

阿拉伯塔尔河(Arabitragus jayakari)只出现在阿曼北部和阿拉伯联合酋长国的山区。由于种群数量下降幅度较小,该物种被列为濒危物种。在这项研究中,我们结合遗传和景观生态学技术,为阿拉伯塔尔的景观尺度保护和遗传管理提供信息。使用 53 个样本数据集中的 540 个线粒体控制区碱基对,我们发现了八个单倍型,它们分为两个单倍群。使用一组 14 个微卫星位点的群体遗传分析也显示出微弱但显着的分裂。景观连通性分析支持遗传结果,表明研究区最南部和北部人口之间的连通性较差。确定了连接阿拉伯塔尔种群的走廊的最可能位置。tahr 种群之间的许多走廊受到多车道高速公路的阻碍,需要恢复这些连接以维持阿拉伯 tahr 种群的生存能力。由于 Wadi Sareen 之外的遗传样本有限,需要进一步采样以更全面地阐明 mtDNA 和阿拉伯塔尔河的核结构。我们的研究提供了一个工具包,可用于未来阿拉伯塔尔种群的遗传和连通性监测。电子补充材料本文的在线版本(10.1007/s42991-020-00072-4)包含补充材料,可供授权用户使用。tahr 种群之间的许多走廊受到多车道高速公路的阻碍,需要恢复这些连接以维持阿拉伯 tahr 种群的生存能力。由于 Wadi Sareen 之外的遗传样本有限,需要进一步采样以更全面地阐明 mtDNA 和阿拉伯塔尔河的核结构。我们的研究提供了一个工具包,可用于未来阿拉伯塔尔种群的遗传和连通性监测。电子补充材料本文的在线版本(10.1007/s42991-020-00072-4)包含补充材料,可供授权用户使用。tahr 种群之间的许多走廊受到多车道高速公路的阻碍,需要恢复这些连接以维持阿拉伯 tahr 种群的生存能力。由于 Wadi Sareen 之外的遗传样本有限,需要进一步采样以更全面地阐明 mtDNA 和阿拉伯塔尔河的核结构。我们的研究提供了一个工具包,可用于未来阿拉伯塔尔种群的遗传和连通性监测。电子补充材料本文的在线版本(10.1007/s42991-020-00072-4)包含补充材料,可供授权用户使用。我们的研究提供了一个工具包,可用于未来阿拉伯塔尔种群的遗传和连通性监测。电子补充材料本文的在线版本(10.1007/s42991-020-00072-4)包含补充材料,可供授权用户使用。我们的研究提供了一个工具包,可用于未来阿拉伯塔尔种群的遗传和连通性监测。电子补充材料本文的在线版本(10.1007/s42991-020-00072-4)包含补充材料,可供授权用户使用。
