The cao vit gibbon is a critically endangered species. Only approximately 110 individuals remain in degraded karst forest along the China-Vietnam border. Karst forest is unusual gibbon habitat. Currently, the canopy height of cao vit gibbon habitat is approximately 10 m. Research on the locomotor behavior of gibbons living in this particular forest type(More)
The Cao Vit gibbon (Nomascus nasutus) was rediscovered in 2002 in Vietnam and then in 2006 in China. This is the only known population with about 110 individuals located along the China-Vietnam border. Little is known about it other than its population size and distribution. We describe the social structure and group dynamics of the Cao Vit gibbons in China(More)
Peripheral populations are valuable for conservation because of their potential genetic distinctiveness and ecological differentiation, but they tend to be smaller and more easily isolated than central populations. The Indochinese gray langurs living in the Wuliang Mountains of southwestern China, which form the northernmost peripheral population of the(More)
Food acquisition is an important factor in the evolution of primate postural behavior. Gibbons are well known for their ability to exploit terminal branches by means of below branch suspensory feeding, but few studies of gibbon positional behavior have been conducted since the seminal work of the 1970s and 1980s. We studied the feeding posture of three cao(More)
The Nangunhe Nature Reserve in Southwest Yunnan (PRC) has long been presumed to be the last stronghold of lar (or white-handed) gibbons (Hylobates lar) in China and the likely last place of occurrence of Hylobates lar yunnanensis. We conducted a comprehensive survey to assess the status of lar gibbons at Nangunhe. We found no visual or auditory evidence of(More)
