We conduct research on primate ecology, behavior, social structure, and conservation of primates and their habitats based largely on field work.
We study the population dynamics, feeding and behavioral ecology of Japanese, African, and Southeast Asian primates. Our aim is to reveal how wild primates and their environments interact with each other through various ecological process, such as competition, predation, symbiosis, and parasitism, and to make the
best use of such knowledge for the conservation of primates and their habitats.
Members of this section conduct behavioral and ecological research on wild, provisioned and captive primate populations in Japan, and on wild populations in various countries across Africa and South/Southeast Asia. Recent topics of interest include the speciation process of bonobos in DR Congo, female transfer, reproductive ecology and personality in bonobos. In Asia, research is being conducted in Japan, China, Indonesia, Malaysia, Sri Lanka, India, Thailand and
Vietnam on topics including feeding ecology, phylogeography, disease ecology, sexual behavior, vocal communication and behavioral endocrinology.
