Sleep is a vulnerable state for animals as it compromises the ability to detect predators. The
evolution of shelter construction in the great apes may have been a solution to the trade‐off …

Primates spend a significant proportion of their lives at sleeping sites: the selection of a
secure and stable sleeping tree can be crucial for individual survival and fitness. We …

In various respects anthropology has developed along paths leading into isolation. It no
longer should hesitate to stake clear claims for all of primatology, now that the comforting old …

We studied the ranging behavior of a habituated group of black crested gibbons (Nomascus
concolor jingdongensis) in a high, seasonal habitat on Mt. Wuliang, central Yunnan, China …

Gibbons are highly territorial and have two key areas within these territories. The core area
in which we find all sleeping trees and the trees from which the gibbons duet and the wider …

We used data on loud duetted and solo songs collected from one habituated polygynous
group of black‐crested gibbons (Nomascus concolor jingdongensis) on Mt. Wuliang …

Gibbons are generally reported to live in small socially monogamous family groups in which
both sexes disperse when they reach maturity. For the first time, we documented the …

When choosing their sleeping sites, primates make adaptive trade‐offs between various
biotic and abiotic constraints. In human‐modified environments, anthropic factors may play a …

Selection and use patterns of sleeping sites in nonhuman primates are suggested to have
multiple functions, such as predation avoidance, but they might be further affected by range …

Several factors are likely to control sleeping site selection and presleep behavior in
nonhuman primates, including predation risk and location of food resources. We examined …
