摘要

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.
