摘要
了解野生有蹄类动物种群的遗传结构对于知情的保护规划至关重要，特别是在喜马拉雅山等生态敏感和地形复杂的地区。利用8个微卫星位点对喜马拉雅山脉西部（WH）和东部（EH）地区巴拉尔（Pseudois nayaur）种群的遗传变异进行了研究。我们的分析显示，WH和EH群体之间存在显著的遗传差异，Nei's遗传距离为0.91，双FST值为0.14，表明它们是不同的谱系。WH群体与喜马拉雅巴拉尔（P. n. nayaur）有更大的遗传亲缘关系。相反，EH种群与中国巴拉尔（P. n.）密切相关。因此，WH和EH巴拉尔代表不同的进化重要单位（esu），应作为单独的管理单位（MUs）进行管理。它进一步强调需要制定针对特定区域的保护战略，以保护印度喜马拉雅地区巴拉尔种群的遗传完整性和生态恢复力。
Unveiling genetic variation among Bharal (Pseudois nayaur) in the Indian Himalayas using nuclear markers.
Understanding the genetic structure of wild ungulate populations is essential for informed conservation planning, particularly in ecologically sensitive and topographically complex landscapes such as the Himalayas. We investigated the genetic variation in Bharal (Pseudois nayaur) populations from the western (WH) and eastern Himalayas (EH) using eight microsatellite loci. Our analysis revealed significant genetic divergence between WH and EH populations, with a Nei's genetic distance of 0.91 and a pairwise FST value of 0.14, indicating their delineation as distinct lineages. WH populations showed greater genetic affinity with the Himalayan Bharal (P. n. nayaur). In contrast, EH populations were closely related to the Chinese Bharal (P. n. szechuanensis) of the Tibetan Plateau. Hence, WH and EH Bharal represent distinct Evolutionarily Significant Units (ESUs) and should be managed as separate Management Units (MUs). It further highlighted the need for region-specific conservation strategies to safeguard the genetic integrity and ecological resilience of Bharal populations across the Indian Himalayan Region.
期刊介绍：
Genetica publishes papers dealing with genetics, genomics, and evolution. Our journal covers novel advances in the fields of genomics, conservation genetics, genotype-phenotype interactions, evo-devo, population and quantitative genetics, and biodiversity. Genetica publishes original research articles addressing novel conceptual, experimental, and theoretical issues in these areas, whatever the taxon considered. Biomedical papers and papers on breeding animal and plant genetics are not within the scope of Genetica, unless framed in an evolutionary context. Recent advances in genetics, genomics and evolution are also published in thematic issues and synthesis papers published by experts in the field.
