Outline of Final Research Achievements

I investigated about the mechanism which maintains one male - multi female group in l'Hoest's monkey (Cercopithecus lhoesti). I identified all the individuals of an object group, and collected the behavioral data about the relation between individuals, or the relation between groups. As a result, I found that the behavior to other group had a difference between male and female. They changed relation between individuals flexibly according to social changes, such as group fusion and group fission.
