由于人类活动对栖息地的改变通常被认为是对自然生态系统和野生动物的威胁，因此在设计管理策略或开展保护活动时，充分了解栖息地改变对濒危物种的影响至关重要。黑白色仰鼻猴（Rhinopithecus bieti）在IUCN红色名录中被列为濒危物种，是中国喜马拉雅山脉的特有物种。目前，只有15个群体和2，500个个体留在野外，他们面临着严重的栖息地退化，选择性砍伐房屋和木柴。在西藏的小昌都，由于木材的采伐，栖息地正在恶化。bieti生活在该物种分布区最北部的边缘栖息地。为了了解在极端边缘生境中，该物种对选择性采伐的反应，收集了一组红腹锦鸡儿的生境偏好和食物组成数据。2003 - 2005年在小长渡采集了10头白蛉。猴子在一年中非随机地使用不同的栖息地。次生针叶林（SC）的选择指数最高（>1），表明猴群强烈偏好SC。与原生针叶林（PC）相比，SC中的猴群取食芽/叶较多，花/果/种子较多，地衣较少。膳食多样性显着高于SC比PC。这些结果表明，在短期内，低强度的干扰可能会导致树叶多样性增加，使R。bieti生存在这个边缘栖息地。Am.

As anthropogenic habitat changes are often considered a threat to natural ecosystems and wildlife, a sound understanding of the effects of habitat alteration on endangered species is crucial when designing management strategies or performing conservation activities. Black‐and‐white snub‐nosed monkeys (Rhinopithecus bieti) are categorized as endangered on the IUCN Red List and are endemic to the trans‐Himalayas in China. At present, there are only 15 groups and 2,500 individuals remaining in the wild, and they are facing intense habitat degradation with selective logging for house building and firewood. Habitat deterioration through wood extraction is occurring at Xiaochangdu, Tibet, where one stable group of R. bieti lives in a marginal habitat in the northernmost part of the species' distribution. To understand the species' response to selective logging in an extremely marginal habitat, data on habitat preference and diet composition of a group of R. bieti were collected at Xiaochangdu from 2003 to 2005. The monkeys used different habitats nonrandomly during the year. The selection index for secondary conifer forest (SC), where selective logging has occurred, was the highest of all habitat types (>1), suggesting that the groups strongly preferred SC. The monkeys fed more on buds/leaves, more on flowers/fruit/seeds, and less on lichen in SC than in primary conifer forest (PC). Dietary diversity was significantly higher in SC than in PC. These results indicate that over the short term, low‐intensity disturbances may result in increased foliage diversity that enable groups of R. bieti to survive in this marginal habitat. Am. J.
