云南富合山地区滇金丝猴游走模式的季节性差异

从 2 0 0 0年 11月至 2 0 0 2年 1月 ,我们在云南富合山 (99°2 0′E ,2 6°2 5′N)记录了滇金丝猴 (Rhinopithe cusbieti)的游走以及其他行为 ,以描述猴群行为模式的季节性变化及其对温带环境的适应。由于季节间行为方式的相似 ,我们将冬季和春季、夏季和秋季的数据合并表述。猴群终年以取食树叶为主 ,多在过夜地附近活动。在冬 -春季 ,猴群一般在低海拔的南部地区活动 ,同时缩短日行走距离 ,花费较多的时间取食树叶、竹叶和竹笋 ;而在夏 -秋季猴群的活动模式与冬 -春季相反 ,并取食大量果实。我们将富合地区猴群的季节性游走模式以及食性看作是食物供给和温度变化之间折中的结果 ,这些行为特征和其它温带灵长类的相似。此外 ,过夜地的分布也会影响猴群利用家域内各方格的方式

Seasonal variation in ranging patterns of Yunnan snub-nosed monkeys Rhinopithecus bieti at Mt.Fuhe, China

From November 2000 to January 2002, data on range patterns and other behaviors were collected for a band of Yunnan snub-nosed monkeys Rhinopithecus bieti at Mt. Fuhe (99°20′E, 26°25′N) to describe the seasonal variations of behaviors and their potential adaptations to a temperate environment. Due to the similarities of ranging patterns between following seasons, we pooled data and showed the results in categories of winter-spring and summer-autumn. The monkeys primarily fed on broad leaves and acted around sleeping sites year-round. In winter-spring, the monkeys often stayed at lower altitudes, had shorter daily path distances, and fed more on broadleaves, bamboo leaves and shoots than in summer-autumn, which was characterized by a reverse ranging mode and by incorporating more fruits in their diet. These seasonal ranging patterns and diets suggest that the movements of R. bieti at Mt. Fuhe are results of compromise between food availability and temperature variations and coincide with the ranging patterns of other temperate monkeys. In addition, the distribution of sleeping sites also influenced the pattern of monkeys utilizing different quadrats within home range Acta Zoologica Sinica 50 (5): 691 - 696, 2004].
