Abstract
The troop composition (numbers of adult males,X 1, adult females,X 2, juveniles,X 3, and infants,X 4) of the Japanese macaque,Macaca fuscata, was examined using principal component analysis and discriminant analysis with 35 data sets from its entire distribution range.X 2,X 3 andX 4 showed an equally high, positive correlation with one another. The variations of the troop composition variables were reinterpreted by a component representing the troop “size” and those representing “shape.” The data sets were sorted into three habitat zone groups from north to south. The functions discriminating between the habitat zone groups indicated thatX 2 andX 4 largely suffice for the discrimination. Examination ofX 2 andX 4 revealed that the troops in the south have a greaterX 4/X 2 ratio; however, further examination of this result indicated a relatively high offspring/female ratio only in the disturbed middle habitat zone but no conclusive latitudinal difference of birth rate. The results were discussed in relation to socioecology of the species.
