森林的破碎化和隔离会减少可供栖息地的面积，并导致某些灵长类物种的食物供应减少。非人灵长类动物的生存在很大程度上取决于它们适应环境变化的饮食能力。西部黑冠朱古力分布在越南北方、老挝西北部和中国西南部，但除了在保护良好的乌山森林中进行的研究外，对其饮食知之甚少。无量山和无量山。云南中部哀牢山。本文对滇南芭蕉河一个孤立干扰林中的小种群进行了2年的食物丰富度和食性研究，并与滇南大寨子种群进行了比较。无量。我们发现芭蕉河的长臂猿主要吃水果，但不吃无花果，不像大多数其他的长臂猿种群。藤本植物的果实和成熟的叶子被用来作为替代食物在果树果实稀缺的时期。我们的研究结果表明，在芭蕉河长臂猿栖息地破碎化和隔离消费的各种植物物种，这取决于那些当地可用的，并增加时间花在树上的果实和藤本植物，而不是增加时间花在消费树叶。Am.

Forest fragmentation and isolation can reduce the size of available habitat and lead to lower food availability for some primate species. The persistence of nonhuman primates in fragments depends largely on their ability to adjust their diet in response environmental change. The western black crested gibbon (Nomascus concolor) is distributed in northern Vietnam, northwestern Laos, and southwestern China, but little is known about its diet except from studies in the well‐protected forests of Mt. Wuliang and Mt. Ailao, central Yunnan. We studied food abundance and diet over 2 years in a small group surviving in an isolated and disturbed forest at Bajiaohe, southern Yunnan, and drew a comparison with the population at Dazhaizi in Mt. Wuliang. We found that gibbons at Bajiaohe consumed mostly fruit, but did not eat figs, unlike most other gibbon populations. Liana fruits and mature leaves were used as alternative foods during periods of tree fruit scarcity. Our results indicate that gibbons in Bajiaohe respond to habitat fragmentation and isolation by consuming a variety of plant species, depending on those that are locally available, and increasing time spent feeding on fruits of trees and lianas rather than increasing time spent consuming leaves.
