Explication of proboscis monkeys' society by measure of relatedness
Date:2010/04/22 - 2010/05/18
For getting DNA samples, I collected 84 feces of proboscis monkeys at Surabaya zoo, Indonesia.
I discussed with zoo manager about capturing the monkeys for collecting bloods and/or hairs.
I got positive response from zoo.
After getting permission from zoo and Indonesia government, I will analyze the feces, bloods and hairs samples.
In addition to collect feces, I observed various sexual behaviors such as homosexual mounts and copulations of adult male and female holding infants.
Moreover, I confirmed a male replacement.
From my observation, infanticide seemed to be not occurred, I would confirm from analyzing DNA samples later.
