Patterns of inbreeding avoidance in Temminck's red colobus

摘要

Amongst Temminck's red colobus living in the Abuko Nature Reserve, The Gambia, the mechanism for avoiding close inbreeding may depend on the form of inbreeding. Mother-son inbreeding may be avoided through learned behaviour and possibly secondary transfer by the mother. Father-daughter inbreeding may be limited due to transfer and demographic patterns but also aggression directed at the male from the mountee's mother. Maternal brother-sister inbreeding may be avoided through female transfer patterns. Presummed paternal brother-sister inbreeding is infrequent but does occur and is not discouraged or avoided.
