This field study investigated the social organization, range use and diet of the Yunnan snub-nosed langur Rhinopithecus bieti (Colobinae). Systematic observations were conducted during 11 months over two years on wild individuals of one band of R. bieti at Wuyapiya (28$\sp\circ30\sp\prime$N, 99$\sp\circ12\sp\prime$E), Yunnan Province, the People's Republic of China. Field work included extensive study of lichen ecology. Laboratory analysis investigated the nutritional correlates of food choice.

520 $a This field study investigated the social organization, range use and diet of the Yunnan snub-nosed langur Rhinopithecus bieti (Colobinae). Systematic observations were conducted during 11 months over two years on wild individuals of one band of R. bieti at Wuyapiya (28$\sp\circ30\sp\prime$N, 99$\sp\circ12\sp\prime$E), Yunnan Province, the People's Republic of China. Field work included extensive study of lichen ecology. Laboratory analysis investigated the nutritional correlates of food choice.
520 $a Rhinopithecus bieti at Wuyapiya had a two-tiered social organization. Reproductive units appeared to consist of one male, several females and associated immatures. Fifteen to eighteen of these reproductive units formed a band which was strongly cohesive. The band had approximately 175 members, and covered 25 km$\sp2$ over the two years of the study. The band stayed at high elevations at all times of year (mean: 4082 m).
520 $a The main food was a lichen of the genus Bryoria (79% of feeding records, n = 1229). Compared to the leaves of both angiosperms and gymnosperms at Wuyapiya, lichens were generally high in non-structural carbohydrates and low in protein. Lichens also were low in fiber and contained virtually no phenolics. Lichens were common between 3600 and 4400 m. Bryoria (Usneaceae, aff. B. nepalensis and B. trichodes) was found in virtually every conifer tree (conifers provided 65.6% basal area at the site), and there was more Bryoria at higher elevations. Based on regression of total lichen volumes to crown sizes for 38 trees in four species (Abies georgei, Quercus pannosa, Rhododendron phaeochrysum, Picea likiangensis), there was approximately 200 kg/ha Bryoria in the forests at Wuyapiya. Complete regeneration of lichen, once stripped from a tree, was estimated to take 20 years.
520 $a The spatial and temporal dynamics of lichens apparently are key to social organization and range use in R. bieti. Intra-group food competition may be low due to the ubiquitous nature of Bryoria, and the large patches of Bryoria may induce the formation of large groups. The slow regeneration time of Bryoria requires that a large range be used over the long term.
