摘要

Japanese macaques, visits by nontroop males (NTMs) often diminish the immediate copulation success of high-ranking males, although few studies have conducted a genetic analysis to show their contribution to the gene pool. I used noninvasively collected samples of semen, blood, urine and feces for the analysis of paternity in nine offspring born in two troops living on the island of Yakushima, Japan. I found that five of the nine offspring were sired by NTMs. It is argued that social change, small troop size and the timing of conception are all factors contributing to the NTM's reproductive success.
