摘要

尽管进行了数十年的野外研究,但人们对长臂猿的分子生态学知之甚少,尤其是它们在退化和支离破碎的景观中的扩散能力。极度濒危的西部黑冠长臂猿(Nomascus concolor)已减少到只有约 1300 个个体的小规模、破碎化种群。在迄今为止规模最大的自由活动长臂猿种群遗传研究中,我们从中国的 13 个地点采集了 47 只长臂猿样本,并生成了 15 个多态常染色体微卫星标记。我们在云南发现了三个长臂猿种群集群,分别集中在:1)五梁山和隘老山;2)永德大雪山;3)靠近越南边境的一个孤立的残余种群。在武陵山区,我们发现了四个亚群,其中三个亚群以高海拔杜鹃林为界,另一个亚群与主群隔离开来,与退化的森林和草场相距约 2 公里。最小成本路径分析和阻力隔离模型表明,五莲山国家级自然保护区长臂猿种群遗传距离与避免使用高海拔杜鹃林而选择常绿阔叶林的地理路径显著相关。虽然这些长臂猿可能因近亲交配而降低了杂合度,但我们认为,它们在种群水平上积极避免近亲繁殖,从而保持了高于预期水平的遗传多样性。这项研究为我们了解长臂猿如何与异质环境相互作用提供了新的视角,并拓展了我们对长臂猿分子生态学和保护遗传学的认识。

Landscape and conservation genetics of western black crested gibbons (Nomascus concolor) in China.

Landscape and conservation genetics of western black crested gibbons (Nomascus concolor) in China.

Despite decades of field study, very little is known about the molecular ecology of gibbons, particularly as it relates to their ability to disperse across degraded and fragmentary landscapes. The critically endangered western black crested gibbon (Nomascus concolor) has been reduced to a small, fragmented population with about 1300 individuals. In the largest population genetic study of free-ranging gibbons to date, we sampled 47 of these gibbons from 13 sites in China and generated 15 polymorphic autosomal microsatellite markers. We identify three population clusters of N. concolor in Yunnan centered in 1) the Wuliang and Ailao Mountains, 2) the Yongde Daxueshan Mountains, and 3) an isolated remnant near the border with Vietnam. Within the Wuliang Mountains, we identified four subclusters, three of which are bounded by high-altitude rhododendron forest, and one that is isolated from the main population by ~2 km of degraded forest and pasture. Least-cost path analysis and isolation by resistance modeling demonstrates that the population genetic distances among gibbons in Wuliangshan National Nature Reserve are significantly correlated with geographic paths that avoid use of high-altitude rhododendron forest in favor of evergreen broadleaf forest. Although these gibbons have likely undergone reductions in heterozygosity from recent consanguineous mating, we suggest that their active avoidance of inbreeding on the population level maintains higher than expected levels of genetic diversity. This research provides new insights into how gibbons interact with heterogeneous environments and expands our understanding of their molecular ecology and conservation genetics.

期刊介绍: The objective of the American Journal of Primatology is to provide a forum for the exchange of ideas and findings among primatologists and to convey our increasing understanding of this order of animals to specialists and interested readers alike. Primatology is an unusual science in that its practitioners work in a wide variety of departments and institutions, live in countries throughout the world, and carry out a vast range of research procedures. Whether we are anthropologists, psychologists, biologists, or medical researchers, whether we live in Japan, Kenya, Brazil, or the United States, whether we conduct naturalistic observations in the field or experiments in the lab, we are united in our goal of better understanding primates. Our studies of nonhuman primates are of interest to scientists in many other disciplines ranging from entomology to sociology.
