Abstract Abstract. Recent reviews of field data on marmosets and tamarins (Callitrichidae) conclude that wild callitrichids exhibit a variable breeding system with a high incidence of cooperative polyandry, contrasting with the long-held supposition of monogamy for this Neotropical primate family. In this study on a wild population of golden lion tamarins, Leontopithecus rosalia , approximately 40% of groups contained two non-natal adult males. Both males cared for infants and, in some groups… 

Behavioral and Endocrine Responses in Male Marmosets to the Establishment of Multimale Breeding Groups: Evidence for Non-monopolizing Facultative Polyandry

The findings suggest that the males in newly-formed groups of marmosets do not monopolize breeding and social behavior with the female, and this appears to be the case for 3 reasons.

While female marmosets show no physical signs of estrus, both males and females likely do have some information about the timing of ovulation and varied between groups and over time.

Paternity and social rank in wild chimpanzees (Pan troglodytes) from the Budongo Forest, Uganda.

We analyzed patterns of paternity and male dominance rank in the Sonso community of wild East African chimpanzees (Pan troglodytes schweinfurthii) in the Budongo Forest, Uganda. Our major objective

Behavioral and demographic changes following the loss of the breeding female in cooperatively breeding marmosets

The data provide important evidence from a cooperatively breeding mammal to support Emlen’s model for the evolution of vertebrate families, but they suggest that species-specific inter- and intrasexual competitive strategies should be considered before the model can be applied to other cooperativelybreeding vertebrates.

Signaling of Reproductive Status in Captive Female Golden-Headed Lion Tamarins (Leontopithecus chrysomelas)

It is investigated whether the female's reproductive status is being concealed in golden-headed lion tamarins, which exhibit extensive paternal care and a mainly monogamous/polyandrous mating system.

Mating Systems and Female–Female Competition in the Common Marmoset, Callithrix jacchus

It is indicated that dominant females are not able to control subordinates’ reproduction, suggesting that the flexibility of C. jacchus mating systems is better explained by ICM than by OSM.

Immigration in wild groups of golden lion tamarins (Leontopithecus rosalia)

Aggression by resident tamarins toward potential immigrants appeared to be the proximate factor limiting movement into groups, and potential female immigrants were sometimes chased by male as well as female residents.

Patterns of mate-sharing in a population of Tasmanian Native Hens Gallinula mortierii

We present data on patterns of mate-sharing collected during a seven-year study of Tasmanian Native Hens Gallinula mortierii at Maria Island, off the east coast of Tasmania, Australia. At this site,
