COVER Female African elephants and their dependent offspring live in matrilineal groups led by the oldest female, or matriarch. Research reveals that group members are dependent on the matriarch for their store of social knowledge. The removal of these key individuals, often targets for illegal hunters because of their large size, could have serious consequences for the conservation of this endangered species.
