To better understand ecology and social structure of proboscis monkeys, I studied harem groups of proboscis monkeys in Lower Kinabatangan Wildlife Sanctuary since January 2005.

After completing sample collection, I dried all leaf samples at the Forest Research Center, Sabah, Malaysia, and obtained permission from the director of Herbarium Section to bring plant samples back to Japan.
Nutritional analysis of samples collected on this trip will be conducted in Japan.
In addition to leaf sampling, boat-based survey was conducted along the Menanggul River.
Further, I visited the Sabah Wildlife Department and the Institute for Tropical Biology and Conservation, University Malaysia Sabah and discussed findings from this research with Malaysian collaborators.
