贵阳黔灵公园动物园笼养黑叶猴的行为观察

2004年4月26日至5月25日,在贵阳黔灵公园动物园,采用扫描取样法对其笼养状态下的黑叶猴的日活动节律及活动时间分配行为进行了观察记录并对引起群体活动时间分配的内在和环境因素进行探讨分析。研究结果表明:1.黑叶猴的日活动具有一定的节律性,一天中有9:00~10:30和15:30~16:30两个明显的行为活动高峰期。2.黑叶猴在活动时间分配中:休息占62.3%,取食占15.1%,移动占8.9%,梳理占6.1%,戏耍占2.6%,威胁占0.5%,其它行为约占4.5%,但在活动时间分配上个体间(P<0.01),成体-青年体间(P<0.05)存在明显差。3.统计分析表明黑叶猴的群体、成体、青年体、雄性、雌性以及大部分个体具有显著(P<0.05),或极显著(P<0.01)的左侧优势现象。

Behavioral Observation of Capitved Francois, Langur ( Trachypithecus francoisis) at Qianling Park Zoo, Guiyang, China

From April 26th to May 25th 2004,by means of scan sampling,we recorded the daliy activity rhythm and time budget of captived Francois' langur at Qianling Park.We also analyzed the inter-and outer-causes for this time budget pattern.The results were as follows: 1.Captived Francois' langur at Qianling Park showed significant daily rhythm,with two active peaks,of which one in the morning from 9:00 to 10:30 am,and another in the afternoon from 15:30 to 16:30 pm;2.Francois' langur spent about 62.3% of its time for resting,15.1% for feeding,8.9% for moving,6.1% for groming,2.6% for playing and only 0.5% for threatening and 4.5% for other behaviorl types.Time-budget showed significant differences between individuals(P<0.01),and age-classes(adult and juvenile,P<0.05);3.Francois' langur showed significant(P<0.05)or most significant(P<0.01) left-side superiority,in levels of group and sex-age classes.
