Inuyama Symposium

"Adaptation and Evolution of Cercopithecidae in Africa"

January 6 - 9, 1999

At"FREUDE" (Inuyama International Sightseeing Center)


Forty years have passed, since Kyoto University Primate Research Group started their first field study in Africa. Though great apes seem to have been the focus of interest of the Japanese field studies, our teams of Kyoto University Primate Research Institute also have studied African monkey species of Cercopithecoidea. Gelada baboons and hybrid baboons in Awash in Ethiopia were studied in the1970s, and then we conducted field surveys on mandrills and drills in the forests of Cameroon in the1980s. Some of us conducted studies on primate communities of forest monkey species beside target species. Others conducted studies on patas monkey in the dry area of Cameroon. In the1990s we resumed our studies on geladas and hybrid baboons in Ethiopia, and we have just started our studies on hamadryas baboons in Saudi Arabia. We are also interested in monkey species in Kenya. As our fields and scope of studies have expanded, it is evident that we should examine our knowledge at present, and reassess the scope of our studies.

Kyoto University Primate Research Institute has obtained a Monbusho fund for promotion of the COE Program in these years. Symposiums can be organized as a part of this COE Program. We have a good opportunity to gather and discuss the recent topics concerning the theme, "Adaptation and Evolution of Cercopithecidae in Africa", together with all international participants who have progressed in the studies along this theme.

The field studies on primates have quite changed in the past 40 years, to be interdisciplinary, involving genetics, morphology, physiology and virology besides socio-ecological studies. This symposium involves all these aspects putting baboons in the center of the topics. The systematics of baboons reveals discrepancy between morphological studies and genetical studies. We want to narrow the gap between these two sides of studies in this symposium.
