Abstract

A 16-month study of foraging and ranging among gray langurs (Presbytis entellus) in the Nepal Himalaya revealed that these animals range over larger areas than other gray langurs so far studied and that they show great seasonal differences in foraging and ranging. A summer monsoon and winter dry season characterize the Himalayan climate. During summer, broadleaf forest provides the basic foraging substrate for the langurs, and when its resources fail during the winter dry season, they radically shift their diet and feed largely in meadow, range over wider areas, use their range more evenly and make longer day journeys. It is hypothesized that the ability of the langurs to make these changes in response to the dry season is vital to their survival at the study site.

摘要

一项对尼泊尔喜马拉雅地区灰叶猴（长尾叶猴）觅食和活动范围进行的为期16个月的研究表明，这些动物的活动范围比迄今为止所研究的其他灰叶猴更大，并且它们在觅食和活动范围上表现出很大的季节性差异。喜马拉雅地区的气候特点是夏季季风和冬季旱季。夏季，阔叶林为叶猴提供了基本的觅食场所，而在冬季旱季，当阔叶林的资源枯竭时，它们会彻底改变饮食，主要在草地觅食，活动范围更广，更均匀地利用其活动区域，并且进行更长距离的日间迁徙。据推测，叶猴应对旱季做出这些变化的能力对它们在研究地点的生存至关重要。
