Research: The influence of selective logging and habitat fragmentation on group density, demography and vocalizing behaviors of Mueller's Bornean gibbon (H. muelleri) in Sabah, Malaysia.
Species/Topic: Mueller's Bornean gibbon
Abstract: The Stability of Altered Forest Ecosystems (SAFE) site in Sabah, Malaysia, a large scale habitat fragmentation experiment, offers a unique opportunity to study the effects of fragmentation using a powerful experimental framework. Pre-fragmentation data collection will include auditory sampling via fixed point counts to estimate gibbon group density in logged and unlogged forest. Recordings of gibbon vocalizations will also be taken to investigate the possibility of using individual vocal fingerprints to identify groups at the SAFE site and playback recordings of gibbon vocalizations will be used in an attempt to make visual contact with the gibbon groups and collect demographic data. This project will provide baseline data on gibbon ecology at the SAFE site in preparation for a long-term study on the effects of habitat fragmentation and will also allow for the testing of hypotheses related to the effects of habitat disturbance on gibbon behavior and ecology.
