摘要

The present study reports infanticide among stump-tailed macaques. The incident was observed when the study group was manipulated by introducing the beta-male to the mother infant pair at the breeding centre. As no copulation was observed between the beta-male and the victim's mother, it was safe to exclude the beta-male as the probable father. The infant was 14 months old and still suckling when she was killed. The aftermath of the infanticide was a successful copulation and eventual conception by the victim's mother. This observation was found to be in accordance with the sexual selection hypothesis.
