Community ecology of primates in Danum Valley Conservation Area

Report:HANYA, Goro

Date:2007/10/27 - 2007/11/07

I have conducted my project on the community ecology of five species of diurnal primates in Danum Valley Conservation Area since September 2006. My Malaysian assistants continue collecting data sampling while I am not at the study site. Since the beginning of the project, I have conducted primate census, orangutan nest census and fallen fruit census along a trail of 9. 9 km in length. Since December 2006, I have conducted behavioral observation of one group of red leaf monkeys. I followed them for 22 hours in three days. Every 10 minutes, I recorded the activity (feeding, moving, grooming and resting), the height of the animal and the height of the tree where animals are staying for all the visible individuals. When they are eating, I collected food samples and identified species. Fruiting season seemed to be finishing, and monkeys eat not only fruits but also leaves. I also observed muller gibbons for four hours in two days. On the way back from the study site, I visited Dr. Henry Bernard at University Malaysia Sabah. We discussed on the present status of his new project of proboscis monkeys in Klias river in Sabah, which started in November 2007.
