Outline of Final Research Achievements

We investigated on the intraspecific variation in fore-stomach microbial communities of proboscis monkeys inhabiting mangrove and riverine forests, Sabah, Borneo, Malaysia. We found that proboscis monkeys have a similar microbe community to that in ruminants including Ruminococcus sp., Prevotella sp., Oscillospira sp. and Selenomonas sp. In addition, the diversity of microbe community was much higher in the proboscis monkeys living in a riverine forest compared to those in a mangrove forest, suggesting that the differences of their food habits between riverine and mangrove forests strongly influence their microbe community.
