One of the major social-biological characteristics in the genus Rhinopithecus is that the animals live in large groups of tens to hundreds of individuals. Study of the distribution pattern of various age-sex classes in the foraging Sichuan golden monkey troop has revealed that the spatial pattern of the Sichuan golden monkey group is an ellipse with its vertical axes longer than the horizontal axes. Most members are concentrated in the center and the center-back.Adult males gather in the front, the center and the back of the troop; adult females and the young assemble in the center and near-center; sub-adult males are mainly distributed in the center-back and back, but some are also seen in the front, front-center and center; sub-adult females are more or less uniformly dispersed. The spatial distribution of various age-sex classes seems well correspondent with their status and role in the group. This result indicates that the spatial distribution strategy adopted by Sichuan golden monkeys is

The spatial distribution of various age-sex classes seems well correspondent with their status and role in the group. This result indicates that the spatial distribution strategy adopted by Sichuan golden monkeys is ecologically adaptive.
