On the organization and structure of a provisioning group of Sichuan snub-nosed monkeys in Qinling Mountains of China

从 2 0 0 2年 3月到 2 0 0 3年 5月 ,在秦岭北坡周至国家级自然保护区玉皇庙西梁 ,我们采用野外跟踪法和扫描动物取样法对一个川金丝猴投食群的组成和结构进行了观察 ,结果发现这个群是由 8个社会单位组成的 ,平均每个家庭有一个成年雄性、3 .75个成年雌性、1.1个亚成年雌性和 3 .75青少年猴组成 ,春季是产子季节 .金丝猴的社群结构是一雄多雌母系社会 .两年的繁殖情况比较分析 ,发现川金丝猴在野生条件下更倾向于隔年生育 .

Based on the tracking monkeys and scan sampling methods, the organization and structure of a provisioning group of Sichuan snub-nosed monkey were conducted from March 2002 to May 2003 in Zhouzhi Natural Reserve in the north slope of the Qinling Mountains of China. The results revealed that the whole group was composed of 8 one-male-units, each of which is made up of one adult male, 3.75 adult female, 1.1 sub-adult female and 3.75 Juvenile respectively. 12 newborn babies were found in breeding season. The result also shows golden monkey society is one male unit matrilineal societies. Comparing with the group' reproduction both 2002 and 2003, we find the species inclines to reproduce every other year.
