Community ecology of primates in Danum Valley Conservation Area
Date:2008/02/16 - 2008/02/24
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 started to observe other primates in May 2007.
This time, I followed red leaf monkeys for 17 hours in three days, pig-tailed macaques for 1 hour in one day, and muller gibbons for 6 hours in two 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.
During the stay, my assistant collected fresh carcasses of a gibbon, flying lemur, and bushy crested hornbill.
The carcasses were photographed and kept frozen.
