Abstract：Group-living imposes costs and provides benefits for animals. While potential benefits may include decreased predation risk and greater defense of important resources,one of most prominent cost associated with group living is an increase in intra-group competition for important resources. Dominance rank is a common regulating resource fashion in group-living nonhuman primates,influencing the distribution of dominance resource among individuals. Aiming to establish the correlation between spatial position and female rank in golden snub-nosed monkeys,we selected four one-male units (OMU)of provisioned Qinling golden snub-nosed monkeys as target units during September 2009 and January 2010,by setting various spatial position of different density,to calculated the gain extent of dominance resource depend on the frequency and duration of dominance spatial position occupancy,at Yuhuangmiao village in the Zhouzhi National Nature Reserve in the north slope of Qinling Mountains,China. Our results showed that female ranks during feeding and resting periods were consistent,and they were positively correlated with the rank orders which were determined by displacement using Spearman Correlation Test. This study showed that compared with dominance index of displacement,the dominance index of defending dominant resources was feasible and easier in operation and statistic,and can determine female ranks quickly. The dominance index of defending dominant resources may facilitate the study of individual ranks in non-human primates under captivity and provisioning conditions of nature as a new determining method.
