Resumen
DANIEL, João R.; SANTOS, António J. y VICENTE, Luís. Dominância e atracção social num grupode macacos-verdes (Cercopithecus aethiops) em cativeiro. Aná. Psicológica [online]. 2008, vol.26, n.3, pp.519-530. ISSN 0870-8231.
Data of grooming interactions, collected through four months of direct observation of a captive group of vervet monkeys (Cercopithecus aethiops), in Lisbon Zoo, were used to test Seyfarths (1977) classical model of rank related attractiveness. Each individual was observed for a total of 10.5 hours by means of focal sampling. All occurrences of agonistic behaviours were also recorded. Analyses confirmed that in females grooming is directed up the hierarchy, despite the interchange of grooming for support not being the underlying principle of this attraction. Considering biological markets theory, the fact that groom dyads tend to be highly non-reciprocal may actually suggests that other commodities, besides support, are being traded.
