Group territoriality associated with aggressive intergroup interactions is characteristic of most cooperatively breeding species. Neighbours, however, are not only competitors but also potential mates. Intergroup interactions might provide a direct mechanism for the assessment of breeding opportunities in neighbouring groups. I studied 228 intergroup interactions in wild cooperatively breeding common marmosets to understand how animals might balance their cooperation in territorial defence with… 


Abstract Defense of group-held resources is a common and widely accepted function of territorial interactions between neighboring groups. In addition, territorial interactions could provide

Sociality in Callithrix penicillata: II. Individual Strategies During Intergroup Encounters

The results suggest that a possible reproductive strategy used by males is to attempt fertilization of extragroup females, which suggests sperm competition or the establishment of social bonds with neighboring females.

Two Breeding Females within Free-Living Groups May Not Always Indicate Polygyny: Alternative Subordinate Female Strategies in Common Marmosets (Callithrix jacchus)

It is suggested that free-ranging C. jacchus groups characterized as monogamous were essentially monogamous groups that occasionally had 2 reproductive females and between-group copulations seem to be an alternative strategy used by the subordinates.

Sex, rank and age differences in the Japanese macaque (Macaca fuscata yakui) participation in inter-group encounters

Data indicate that in non-territorial species with male dominance over female and high competition for mating partners males play an active, and often aggressive, role during inter-group encounter while female participation is scarce.

Helpers influence on territory use and maintenance in Alpine marmot groups

It is found that groups having higher proportion of helpers, rather than higher total number of individuals, had lower percentage of the territory overlapping with neighbouring groups and a larger area available for individual exclusive use.

Behavioral strategies and hormonal profiles of dominant and subordinate common marmoset (Callithrix jacchus) females in wild monogamous groups

The behavioral and hormonal profiles of common marmoset (Callithrix jacchus) females living in three wild monogamous groups, varying from five to 11 individuals, at Nísia Floresta field station, RN, Brazil are described.



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.

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.

Individual Contributions To Cooperative Behaviour in the Acorn Woodpecker: Effects of Reproductive Status, Sex, and Group Size

It was predicted that breeders should invest more heavily in cooperative behaviour than should helpers, and the prediction was upheld: for nearly every form of cooperative behaviour examined, breeders contribute significantly more than do helpers.

Group size and aggression: ‘recruitment incentives’ in a cooperatively breeding primate

Investigation of the association between group size and aggression towards strangers in Wied's black tufted-ear marmosets, Callithrix kuhlifrom small groups and large groups reveals that breeders from small groups are tolerant of strangers, which may facilitate the recruitment of additional group members, whereas breeder from large groups, particularly females, are intolerant of strangers which may inhibit immigration.

Behavioural evidence for monopolization of paternity in multi-male groups of golden lion tamarins

A demographic model indicated that a currently non-reproductive subordinate male that waited for the dominant male in his group to die or for a breeding vacancy in an adjacent group could expect higher lifetime reproductive success than a male that left a subordinate position in search of breeding opportunities elsewhere.

Social organization of cooperatively polyandrous White-winged Trumpeters (Psophia leucoptera)

The evolution of cooperative breeding in White-winged Trumpeters appears to be related to the need to defend large permanent territories to provide access to sufficient food during the dry season when resources are scarce.

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.

In well‐established families, a familiarity or inbreeding taboo restricted reproduction among otherwise fertile offspring, however, only one daughter ovulated in any family, and in up to 50% of family groups, all daughters were inhibited from ovulating.

Sex ratio and habitat limitation promote delayed dispersal in superb fairy-wrens

The interaction between habitat limitation, habitat quality, and sex ratio in influencing dispersal decisions in a population of superb fairy-wrens is investigated and suggests that young males delay their dispersal in response to a limited number of mates and secondarily to habitat limitation.

Social organization in a wild population of Callithrix jacchus. I. Group composition and dynamics.

The group dynamics described in studies of other populations of Callithrix suggest that extended family groups, or at least groups consisting of breeding individuals and their close relatives, may be characteristic of those populations.
