The Qinling mountainous region is one of the world's biodiversity hotspots and provides refuges for many endangered endemic animals. The golden snub-nosed monkeys () are considered as a flagship species in this area. Here, we depicted the genetic structure and evolutionary history via microsatellite markers and combination with the ecological niche models (ENMs) to elucidate the intraspecific divergent and the impacts of the population demography on our focal species. Our results revealed three distinct subpopulations of and also uncovered asymmetric historical and symmetric contemporary gene flow that existed. Our evolutionary dynamics analyses based on diyabc suggested that the intraspecific divergence accompanied with effective population sizes changes. The ENM result implied that the distribution range of this species experienced expansion during the last glacial maximum (LGM). Our results highlighted that geological factors could contribute to the high genetic differentiation within the in the Qinling Mountains. We also provided a new insight into conservation management plans with endangered species in this region.
秦岭山区是世界生物多样性热点地区之一,为许多濒危特有动物提供了避难所。川金丝猴被视为该地区的旗舰物种。在此,我们通过微卫星标记并结合生态位模型(ENMs)描绘了其遗传结构和进化历史,以阐明种内分歧以及种群动态对我们重点研究物种的影响。我们的结果揭示了川金丝猴的三个不同亚种群,还发现了存在的不对称历史和对称当代基因流。基于diyabc的进化动态分析表明,种内分歧伴随着有效种群大小的变化。生态位模型结果表明,该物种的分布范围在末次盛冰期(LGM)期间经历了扩张。我们的结果突出表明,地质因素可能导致秦岭山区川金丝猴的高度遗传分化。我们还为该地区濒危物种的保护管理计划提供了新的见解。
