Number of males that established home ranges did not significantly differ among enclosures, but body weight distributions of the male populations differed significantly between enclosures, and at the end of the experimental period, differed between enclosures where the body weight distributions were similar at the time of introduction. The number of females whose home range overlapped with that of a male and the number of males whose home ranges overlapped with that of a female did not differ significantly among the enclosures. The correlations between 7 male characteristics were greatest in enclosures in which variance in the body weight distribution at the time of the introduction was large. The paternity of the offspring of 29 females could be determined. Multiple paternity was found in 6 cases. Males with higher relative body weight at the time of introduction tended to mate more successfully. -from Author
