| Resumo: | Marmosets are cooperative breeders organized as extended family groups, but breeding is generallyrestricted to a single pair. Breeding competition is fierce in female marmosets; males, on the other hand,show low levels of intragroup aggression. We investigated male and female breeding strategies andthe resulting reproductive output in 9 wild groups. Reproductive output, tenure of breeding animals,identification of the breeding system, breeding position replacements, migration and infanticide wererecorded; also, we recorded grooming and aggression. Replacement of the breeding male or female wasobserved on nine occasions. On four occasions, the son of the breeding male inherited the breeding post,but we never observed inheritance of a breeding post by a daughter. Mostly, females attained a breedingpost by immigrating to a group that had a breeding vacancy. Our results showed that Callithrix jacchusmales and females use different strategies to attain a breeding position and maintain it for as long aspossible. These strategies prolong the tenure of the breeding position, which is the best way to producea large number of offspring |
