“…Sheer semibarren rock walls are sometimes used for sleeping by some populations of sacred langurs, Semnopithecus spp. (Vogel 1975;Boggess 1980). Black-and-white snub-nosed or golden monkeys (Rhinopithecus bieti) have a limited distribution in northwest Yunnan and southeast Tibet, where they inhabit alpine forests (Long et al 1994).…”

We examined the criteria for sleeping place selection in a social band of Rhinopithecus bieti (black-and-white snubnosed or golden monkeys) living in the mountainous Samage Forest, Baima Snow Mountain Nature Reserve, Yunnan, China. We performed principal component analysis and found that slope aspect, tree height and trunk diameter were likely key variables influencing selection of sleeping places. Sleeping sites were preferentially located in mixed deciduous/conifer forest. The monkeys slept exclusively in evergreen trees, of which 82% were conifers (mostly Picea likiangensis and Tsuga dumosa) and 18% evergreen oaks (Cyclobalanopsis oxyodon and Quercus spp.). Sleeping trees were tall (mean 30.5 m), had high boles (mean 18.4 m), large diameters (mean 62.6 cm) and large crown areas (mean 57.9 m 2 ). A comparative analysis of phytological and architectural features between trees in "sleeping site plots" (n = 18) and trees in "non-sleeping-site plots" (n = 66) revealed that diameter, crown surface area and tree height were significantly (P < 0.01) larger in the former compared with the latter. All investigated roosting sites were situated on steep mountain slopes. Valleys and mountain ridges were avoided. We also detected re-use of roosting sites on several occasions, but not on consecutive nights. It is most likely that a mix of factors (stability of trees, access to food, unit cohesion, monitoring potential) explains the pattern of sleeping site preference, but predation at night seems to be only slightly important. Climate appears to have a profound influence on patterns of sleeping site selection in the monkeys' harsh temperate habitat. This is demonstrated by the monkeys' preference for mixed forest at medium elevations over montane fir forest at high elevations and slopes instead of ridges, with reduced exposure to wind and precipitation inherent in the former. We also emphasize the possibly substantial role that non-environmental factors (the nature of social organization and socio-behavioral strategies) play in determining sleeping site use in R. bieti and other primates.

“…All known births occurred between December and April, with sexual activity most pronounced between May and October. For a more detailed discussion of the study site and langur population see Curtin [1975] and Boggess [1980].…”

“…Variability in social structure was a key issue drawn from the early langur studies [Yoshiba, 1968], More recent studies have focused attention on the phenomenon of male competition for mates and the manner in which male competition is related to infant killing, social dynamics among males, and adult male residence patterns in bisexual groups [Hrdy, 1974a[Hrdy, , b, 1977[Hrdy, , 1979Curtin, 1977;Curtin and Dolhinow, 1978;Boggess, 1979Boggess, , 1980Vogel, 1979], Yet, the related topic of social relations between imma ture and adult males has been largely ignored. To date, even the most extensive published descriptions of social relations between young and adult free-ranging langurs have been brief, generally qualitative accounts [Jay, 1965;Mohnot, 1978;Yoshiba, 1968], although some quantitative data on this topic exist in doctoral dissertations [Jay, 1962;Bishop, 1975].'…”

Immature Male and Adult Male Interactions in Bisexual Langur (Presbytis entellus ) Troops

One bisexual troop of langurs (Presbytis entellus) was intensively investigated for 32 months at the Junbesi-Ringmo study site in Nepal. Observations occurred during three separate studies and span a period of 6 years. All members of the study troop could be individually recognized throughout the three studies. During this investigation data were collected on immature male (from birth to 5 years of age) social relations with adult males. Social relations between these two classes of males varied both in type and in frequency of behaviors displayed. During the first study, when the troop was predominantly multi-male, young males directed various tense behaviors toward adult males. Monthly rates of occurrence of such behaviors fluctuated and showed a positive correlation with rates of agonistic behaviors between adult males. In contrast, interactions between the adult and immature males were considerably more relaxed during the second and third studies when the troop had but 1 adult male. Based on the results of these studies, and data evaluated from other studies of P. entellus, it is hypothesized that the frequency and patterning of interactions between adult males affect adult male relations with young males.

“…Male-male fighting is infrequent within groups because one male often monopolizes mates and evicts rivals. However, this calm evaporates when multiple males compete (Boggess, 1980;Borries, 2000). If modern humans retain traces of such a social organization, one should see higher vigilance among males watching for nongroup rivals, and a significant increase in distractions and within-group vigilance when male rivals co-reside in a group.…”
