摘要极危海南长臂猿是世界上最受威胁的灵长类动物之一，现仅存于海南省霸王岭国家级自然保护区。我们描述了人口动态的变化，以及目前的个人数量，根据历史资料和实地调查在2002-2013年。种群由三个独立的群体中的总共20个个体（包括6个孤独的雄性）组成。它们都被限制在C的区域内。16平方公里。目前的种群在2002年由两个群体发展而来，共有13只个体，自那时以来，随着一个新群体的加入，种群数量缓慢增加。人口增长受到一个成年男性和两个成年女性的独特社会结构的阻碍，以及成年女性的生育年龄限制。后代性别比例失衡也可能阻碍了种群恢复，但需要对此进行进一步调查。我们的研究结果表明，在未来的几十年里，海南岛的珊瑚礁可能仍然处于极度濒危状态。
Abstract The Critically Endangered Hainan gibbon Nomascus hainanus is one of the most threatened primate species and is now found only in the Bawangling National Nature Reserve of Hainan Province, China. We describe changes in population dynamics, and the current number of individuals, based on historical sources and fieldwork during 2002–2013. The population comprises a total of 20 individuals (including six solitary males) in three separate groups. All are confined to an area of c. 16 km2. The current population developed from two groups that comprised a total of 13 individuals in 2002, and has increased slowly since then, with the addition of one new group. Population increase is hindered by the gibbon's unique social structure of one adult male and two adult females, as well as the reproductive age limit in adult females. An imbalance in the sex ratio of offspring may also have hindered population recovery but further investigation of this is required. Our findings indicate that the Hainan gibbon is likely to remain Critically Endangered in the coming decades.
