由于狩猎和栖息地丧失的协同效应，西部黑冠长臂猿的种群目前仅限于孤立的森林碎片。与其他灵长类动物一样，该物种在破碎森林中的活动范围推测与空间、食物和植被属性有关。我们研究了中国云南南部八角河一片孤立且受干扰的森林中不同食物资源的分布、植被结构（树木密度、胸径和高度）以及一个长臂猿群体的微生境利用。结果表明，长臂猿经常使用边缘栖息地，这些栖息地比内部森林受到更多的人为干扰，并且它们似乎通过使用竹子和草果植物来适应不连续的树冠覆盖。该群体还根据食物供应和当地植物群的波动调整了饮食。然而，在两个研究期间，长臂猿集中使用了树木果实可用性高的地区。这表明该群体的微生境利用主要受到特定食物资源分布和选择性伐木造成的树冠间隙的影响。保护当前分布区并种植本地重要食物物种以提高栖息地质量和连通性应被视为生活在有限区域的西部黑冠长臂猿保护计划的一部分。
Due to the synergistic effects of hunting and habitat loss, populations of the western black-crested gibbon are currently restricted to isolated forest fragments. The home range use of this species in fragmented forests is presumptively related to spatial, food and vegetation attributes, as in other primates. We examined the distributions of different food resources, the structure of the vegetation (tree density, DBH, and height), and the microhabitat use of one gibbon group in an isolated and disturbed forest at Bajiaohe in southern Yunnan, China. The results indicated that the gibbons used the edge habitat frequently, which was subject to more anthropogenic disturbance than the interior forest, and they appeared to adapt to discontinuous canopy cover by using bamboo and tsaoko plants for travel. The group also modified its diet in response to fluctuations in food availability and the local flora. However, the gibbons intensively used areas with high tree fruit availability across the two study periods. It is suggested that the microhabitat use by the group was mostly affected by the distribution of particular food resources and canopy gaps caused by selective logging. Protecting the current distribution area and planting native important food species to boost habitat quality and connectivity should be considered as part of conservation plans of the western black crested gibbon living in limited areas.
