神农架自然保护区川金丝猴投食群友好行为的初步观察

为探讨人工补食条件下川金丝猴(Rhinopithecus roxellana)的友好行为因补食产生的影响,2007年1～9月,采用行为取样法、扫描取样法和全事件记录法对湖北神农架自然保护区大龙潭投食猴群的友好行为进行了观察.共记录到11种友好行为,发生频次居前的是理毛、张嘴、拥抱、游戏、趋近.友好行为的发起者和承受者在性别间差异均不显著,但在年龄间差异均显著.在一雄多雌单元内发起者按次数多少为成年、少年、青年、亚成年猴,承受者的顺序亦如此.在全雄单元内发起者按次数多少为成年、少年、亚成年、青年猴,承受者的顺序亦如此.友好行为在单元内和单元间差异显著,单元内多于单元间.这在一定程度上说明川金丝猴社会单元内个体间的关系紧密,单元间的关系相对疏远.友好行为在繁殖和非繁殖季节差异不显著.

Preliminary Observation on Affiliative Behaviors of Rhinopithecus roxellana in a Provisioned Group in the Shennongjia National Nature Reserve

To evaluate the effects of provisioning on affiliative behaviors of Sichuan Snub-nosed Monkeys(Rhinopithecus roxellana),we conducted a systematic observation on a group in the Shennongjia National Nature Reserve from January to September 2007 by using behavior sampling,scanning sampling and all-occurrence recording methods.The group consisted of 3 one-male units(OMU)and 1 all-male unit(AMU)with 45 individuals in total.Eleven types of affiliative behaviors were defined and recorded.Allo-grooming,opening mout...
