Socio-ecological study on pig-tailed macaques in Malaysia

Report: Yosuke Otani

Date: 2012/10/6 - 2012/12/25

 By comparing the social features among different species inhabiting different environment, we can reveal a part of the mechanisms of the evolution of social structure. Species of genus Macaca are suitable subjects for this study because the group includes nineteen species and inhabit in various habitat types, from temperate to tropical zone. Therefore I plan to compare social features of pig-tailed macaque (Macaca nemestrina) and Japanese macaque (Macaca fuscata).

 I conducted direct observation by using VHF telemetry system to reveal their activity, food repertoire, and ranging behavior. Finally macaques allowed us to close 30-10m at minimum. However, we need further effort to record their activity because of the dense bush of tropical rain forest.
