| 中文摘要: |
| 2008年12月至2009年4月在梵净山国家级自然保护区东北部岩高坪片区对黔金丝猴（Rhinopithecus brelichi）昼间休息行为进行了研究。采用随机取样法（ad libitum sampling），观察记录黔金丝猴个体的休息姿势、休息位置的林层高度、休息时利用支撑物树枝的粗细与倾斜角度以及团抱组合的个体数量等休息行为相关参数。研究发现黔金丝猴昼间休息行为主要选择利用林层的树冠中位，占总频次的52%；黔金丝猴的休息姿势主要为坐姿，占总频次的99%，偏好利用直径介于5 ~ 10 cm之间中等粗细树枝作为支撑物；选择支撑物树枝的倾斜角度趋近于水平；昼间休息多采用2只个体组成的团抱模式；猴群休息位置支撑物树枝直径与树冠层高度呈显著负相关；黔金丝猴在树冠各层间休息时的平均团抱大小差异显著。树冠层支撑物资源在树冠的垂直分布可能是黔金丝猴昼间休息行为利用树冠层高度与团抱模式的主要影响因子。 |

| There is currently little information on resting behavior of wild Guizhou snub-nosed monkeys (Rhinopithecus brelichi). This field study on the ecology and behaviors of this species was conducted in Fanjingshan National Nature Reserve, China. Parameters related to resting behavior including the posture, forest/tree strata, support diameter and inclinations, and numbers in huddling groups were recorded by ad libitum sampling method from December 2008 to April 2009. Our results showed that sitting was the most common posture (99%); the middle tree stratum was most frequently used (52%) during resting periods; the medium diameter of support branches (5﹣10 cm) and the approaching level of support branches inclinations were most frequently used (Table 1); and huddling group most frequently comprised of two individuals. And there was a negative correlation between tree strata and the diameter of support branches (r =﹣0.478, P < 0.05, n = 50). There was also a significant difference of average huddling group size between different tree strata (Fig. 1, Fig. 2). Vertical distribution of support resources may influence both huddling group size and tree strata use in Rhinopithecus brelichi. |
