Taking advantage of a marked yearly fluctuation in the number of estrous females, I studied the differences in mating success between troop males and non-troop males in an unprovisioned group of Japanese macaques. Fluctuation in the defendability of estrous females by troop males, as predicted by the operational sex ratio (the number of estrous females per troop male), strongly affected the mating with ejaculation (successful mating) per observation day of both troop and non-troop males.
