Time budgets of Rhinopithecus bieti at Xiangguqing in the Baimaxueshan National Nature Reserve, Northwest Yunnan, China
摘要
Abstract
Studies of time budgets can provide important information about the time allocation patterns,movement rules,and habitat use of nonhuman primates.A large group of up to 480 individual black and white snub-nosed monkeys (Rhinopithecus bieti) living at Xiangguqing (27°37′N,99°22′E),within the Baimaxueshan National Nature Reserve,was observed to determine how monkeys spent their time.Data were collected from June 2008 to May 2009 via instantaneous scan sampling.In total,we observed 260 546 individual activity records,and obtained 1 609 observation hours.Group members spent 38.8％ of their time feeding,27.4％ moving,20.9％ resting,and 12.9％ engaged in other activities.Time budgets showed significant seasonal variation:monkeys spent more time feeding in winter (41.5％),and less in autumn (36.5％).In summer,the group spent more time moving (32.8％) than they did in other seasons.To conserve energy,monkeys rested most often in winter (24.4％).More time was devoted to other activities (15.7％) during autumn.The amount of absolute time spent moving showed a significant positive relationship with day length and monthly mean temperature (P ＜ 0.01).Absolute time spent resting was significantly negatively affected by monthly mean temperature (r =-0.585,P =0.046).Precipitation amount did not influence the time budgets of the study group at all (P ＞ 0.05).Seasonal dietary changes had a strong influence on activity patterns ; monkeys moved less (r =-0.902,P ＜ 0.001) and rested more (r =0.860,P ＜ 0.001) when primarily consuming lichens,moving more often while young leaves or bamboo shoots were abundant (r =0.832,P =0.001).These results suggest that the time budget of R.bieti reflects an adaptation to seasonal variations in diet,day length,and climate.关键词
