Abstract: | We introduced two to four unfamiliar animals into three established groups (N = 6–9 per group) of tufted capuchins (Cebus apella).We present findings on the behavioral consequences of introductions as a function of age, sex, and residency status and long-term
consequences for health and reproduction. No morbidity from aggression occurred at the time of introductions or during several
months following, and reproduction was not compromised. Activity budgets and patterns of social spacing and interaction were
little changed following the introductions except for increases in vigilance behavior, especially by newly introduced adult
females. Adult females exhibited the strongest and longest-lasting response to changes in group composition. The results indicate
that in this species (1) introductions of adult females can be carried out with acceptable risk to the newcomers provided
that careful monitoring occurs, so that the onset of severe aggression instigated by resident females toward new females can
be avoided, (2) juveniles can be introduced with minimal risk, and (3) adult males can be introduced into groups lacking resident
adult males with minimal risk. Capuchins differ in important ways from the better-studied Old World monkeys in their response
to introductions of strangers. The differences are instructive with regard to processes supporting species-typical social
structure, which is less overtly hierarchical in capuchins than in macaques. |
