摘　　要：Infant-care behavior,a range of caring behaviors by parental or alloparental individuals towards infants unable to live independently,plays asignifcant role in the survival of infants and the continuation of the species in non-human primates.During a behavioral ecological study ofTaihangshan macaques,we observed 2 cases of infant adoptions by unrelated adult females.In case 1,a multiparous female adopted a lostinfant from a neighboring group,with the infant being snatched back by her biological mother 35 days after the adoption.This is the frst report ofcross-group adoption in Macaca.In case 2,a nulliparous adult female,who had been once adopted by her elder sister,adopted an orphan fromher group for 36 days.We describe the details of adoptions in Taihangshan macaques and explore possible reasons for adoptions to contributeto understanding the evolution of infant-care behavior and altruistic behavior of adoption in primates.
