[Infanticide in hamadryas baboons].
The results of 20-year study of infanticide cases in hamadryas baboon troop of the Sukhumi colony and 10-year observations in Gumista Natural Reserve are presented. The allopatric behaviour which may be the cause of infant death, is shown to be common for 4-7 year old males. In behaviour of older males directed to the infants the elements of aggression predominate. The majority of injuries and infanticide by males takes place in the situations associated with a dominant male change in the group or with the introduction of new females into the groups. In the groups where the social relationships are not fully organized, the appearance of infant leads to decrease of dominant male function and to appropriation of infant by a male and its traumatizing. As a result of infanticide the infants of young 4-7 year old females die most of all. The death of infants commonly occurs during the introduction of young males into the group. The probability of infanticide during the introduction of older males is lower.
