摘要放牧行为和栖息地利用是生态影响个体行为的重要指标。2005年9月至2006年8月，我们在广西农岗自然保护区石灰岩栖息地收集了两组猕猴(猕猴)的活动行为和栖息地利用的数据。我们评估了食物资源的时空分布对放牧行为和栖息地利用的影响。在研究期间，两个焦点种群的总活动范围分别为53公顷和65公顷；平均每日路径长度分别为590米和782m，远远小于在其他物种猕猴中观察到的路径长度。阿萨姆猕猴并不统一使用它们的活动范围。50%的位置记录发生在各自家庭范围的11%(第1组)和13%(第2组)范围内。在两个研究组中，现场使用的强度与集体进食的分布之间存在显著的正相关。在包括进食在内的维护活动中，猕猴白天71.1%的时间都在悬崖上度过。种群对栖息地的差异化利用和对悬崖的更密集的占领可能与它们的主食资源--板蓝叶的空间分布有关。
Abstract Ranging behavior and habitat utilization are important indicators of ecological influences on individual behavior. We collected data on the ranging behavior and habitat use of two groups of Assamese macaques (Macaca assamensis) between September 2005 and August 2006 in a limestone habitat within Nonggang Nature Reserve, Guangxi, China. We evaluated the influences of spatial and temporal distribution of food resources on ranging behavior and habitat utilization. During the study period, total home range sizes for the two focus groups were 53 ha and 65 ha; mean daily path lengths were 590 m and 782 m, much smaller than those observed in other species of macaques. Assamese macaques did not use their home ranges uniformly. Fifty percent of location records occurred within 11% (group 1) and 13% (group 2) of their respective home ranges. A significant and positive correlation was found between the intensity of site use and the distribution of group feeding for both study groups. Macaques spent 71.1% of the daytime hours on cliffs during maintenance activities, including feeding. The differential utilization of the group’s home range and more intense occupation of cliffs can be related to the spatial distribution of their staple food resources, the leaves of Indocalamus calcicolus.
