Javan Gibbon (Hylobates moloch) Non-Vocal Social Communication and Gesture Use With Conspecifics
… gestures used by captive Javan gibbons (<em>Hylobates moloch</em>) at the Gibbon Conservation Center (Santa Clarita, CA). I hypothesized that a sender gibbon’s gesture modality would vary with the recipient gibbon’s attentional state and the sender would be equally likely to use all …

Group density estimates for lar gibbons (Hylobates lar) and siamangs (Symphalangus syndactylus) and the quantitative analysis of the vegetative characteristics of the Sikundur field site.
Southeast Asia’s tropical forests encompass 20-25% of the world’s plant and animal species. However, at the moment, this region is in the midst of a biodiversity crisis since it is experiencing a higher rate of forest loss than any other region. Indonesia has one of the highest deforestation rates …

Spatial distribution and density of the Lar gibbon Hylobates lar and Siamang Symphalangus syndactylus in relation to canopy structure and disturbance in a lowland dipterocarp forest, Sumatra.
… the two sympatric gibbon species, the lar gibbon Hylobates lar, and the siamang Symphalangus syndactylus. The field study was conducted from 1st March to 1st August 2016 within the Sikundur region of the Gunung Leuser National Park, North Sumatra, where both large and small-scale logging practices …

Effects of seed dispersal by gibbons, sambar, and muntjac on Choerospondias axillaris demography, and the disruption of this mutualism by wildlife poaching
… dispersal of its seeds to light gaps by gibbons (Hylobates lar), sambar deer (Cervus elaphus), and muntjac deer (Muntiacus muntjak). In parks where these mammals are heavily hunted, far fewer seeds are dispersed to light gaps and seedling abundance is significantly reduced. These results suggest …
