Abstract
During observations of silvered leaf-monkeys at Kuala Selangor, Malaysia, the resident adult male in one group was replaced by an immigrant male. Three months after the replacement, all of the dependent infants in the group disappeared. The similarity of these observations to observations of male-takeovers and subsequent infanticide among Indian and Ceylonese langurs suggests a similar pattern of social change among all langurs which live in one-male groups.
