| Outline of Final Research Achievements |
The research was conducted on Western gorillas in the Gabonese Republic, bonobos in the Democratic Republic of Congo, and chimpanzees in Republic of Uganda, under the human-dominant landscape, mainly for their habitat uses and food selections. These African great apes are regarded as representatives of the primeval tropical forests. However, in reality, they depend largely on the fruits and leaves of pioneer plants or terrestrial herbs which are characteristic of secondary forests. The functional traits of the leaves of the tree species were examined, and we found that tree species in the secondary forest have the higher protein and the lower tannin content than those in the primary forest. These functional traits of the leaves are the desirable properties as a food of wild primates.

| Academic Significance and Societal Importance of the Research Achievements |
現在、急激な熱帯林の減少で、野生霊長類を含む多くの動植物が絶滅に瀕している。その代表ともいうべきアフリカのゴリラ、ボノボ、チンパンジーなどの大型類人猿は、じつは人為的な環境である二次林を多く利用し、二次林を構成する樹種の機能形質が食べ物として好ましい性質をもつことが判明した。このことは、これまでのアフリカの大型類人猿のために原生林を中心とし、地域住民を徹底的に排除する保護策ではなく、二次林や農地も含むゆるやかなゾーニングにより、焼畑耕作などを生業とする地域住民との共存に向けた新しい大型類人猿の保護政策の立案に大きく寄与する。
