Abstract: | Paternity in many primate species cannot be established reliably on behavioral grounds. For instance, Japanese macaques (Macaca fuscata) have a multi-male group structure and promiscuous mating patterns. On the other hand, accurate evaluation of male reproductive
success is needed to analyze primate behavior. DNA finger-printing techniques were applied to 2 captive groups of Japanese
macaques in the Primate Research Institute of Kyoto University for identification of paternity. Also, mating behavior of a
captive group was observed in order to compare the reproductive success of each male with that expected on the basis of his
observed mating activity. The number of offspring of full adult males was not related to their social rank although the number
of copulations with ejaculation was highly correlated with their social rank.
Monitoring of the female sexual cycles from the plasma profiles of gonadotropins and ovarian hormones suggested that males
could not choose females at days of ovulation.
The results of two-free-ranging wild troops, like those of the captive groups, indicated that high-ranking males could not
monopolize the paternity of offspring. The results of paternity discrimination in Japanese macaques were compared with results
from patas monkeys (Erythrocebus patas) in a discussion of social structure and male reproductive success. Some aspects of polymorphism detection techniques are
also discussed. |
