Exploring evolution of social relationships and life histories in non-human primates

In many gregarious non-human primates, males tend to disperse from their natal group before sexual maturity and transfer among bi-sexual groups through their lives. Some males successfully transfer into another bi-sexual group soon after the emigration, but others will spend a considerable time as a member of all-male groups or alone as solitary males. Their social relationships with other males are not stable, in other words, interaction partners and extent of time spending on interaction will be drastically changed along with their growth and life stages. I am studying on social relationships among male non-human primates, especially among Japanese macaques, for more than 15 years. I have started study on rhesus macaques, Tibetan macaques, and Yunnan snub-nosed monkeys recently. I’m challenging to examine the evolutional process of male social relationships and life histories.

Recent Interests:

I started the project to examine dispersal patterns of male rhesus macaques using GPS collars. Direct observation methods provide behavioral data with good quality but at the same time they will face disadvantages due to the time and resource limitation. GPS telemetry system is an effective data collection method compensating fort those disadvantages. I’m challenging to the integration of direct and indirect observation methods for data collection. Also, I‘d like to collaborate with primatologists and anthropologists to expand our knowledge about evolutional process of sociality.
