海南长吻金丝猴（Nomariahainanus），曾经广泛分布于中国海南，现在只在霸王岭国家级自然保护区发现。它是世界上最稀有的灵长类动物，种群数量为33只。栖息地丧失和破碎化是导致海南大熊猫种群数量下降的主要原因。在这项研究中，我们整合了基于实地调查和基因型分析的10个微卫星位点（粪便样本）的数据，以评估这一极度濒危灵长类物种的遗传多样性。结果表明，海南长吻金丝猴的遗传多样性极低，8个微卫星位点中有7个位点的遗传多样性降低。额外的分子分析与野外观察结果一致，表明A、B和C组中的个体亲缘关系密切，后代的雌雄性比明显偏离1：1，预计世界上剩余的海南长颈鹿种群将在未来经历持续的高水平近亲繁殖。由于栖息地的大量丧失（99.9%的自然范围已被砍伐）和破碎化，这种最稀有的猿类物种面临灭绝，除非立即采取纠正措施。
The Hainan gibbon (Nomascus hainanus), once widespread across Hainan, China, is now found only in the Bawangling National Nature Reserve. With a remaining population size of 33 individuals, it is the world’s rarest primate. Habitat loss and fragmentation are the primary drivers of Hainan gibbon population decline. In this study, we integrated data based on field investigations and genotype analyses of 10 microsatellite loci (from fecal samples) to assess genetic diversity in this Critically Endangered primate species. We found that the genetic diversity of the Hainan gibbon is extremely low, with 7 of 8 microsatellite loci exhibiting decreased diversity. Additional molecular analyses are consistent with field observations indicating that individuals in groups A, B, and C are closely related, the female–male sex ratios of the offspring deviates significantly from 1:1, and the world’s remaining Hainan gibbon population is expected to experience continued high levels of inbreeding in the future. Given extensive habitat loss (99.9% of its natural range has been deforested) and fragmentation, this rarest ape species faces impending extinction unless corrective measures are implemented immediately.
