Allomaternal interactions in the Bolivian squirrel monkey (Saimiri boliviensis boliviensis)

Dorsal clinging on allomothers occurred most frequently when the infants were younger and more dependent, and declined with the infant's growing independence, and future studies need to be directed toward establishing the proximal causes of allomaternal behavior in the squirrel monkey.

Alloparenting is associated with reduced maternal lactation effort and faster weaning in wild chimpanzees

The effects of alloparenting on the speed with which infants were weaned in wild chimpanzees at Ngogo, Uganda is investigated and a novel measure of the contribution of milk to infant diets through faecal stable nitrogen isotopes is presented.

Infant handling by female Barbary macaques (Macaca sylvanus) at Affenberg Salem: testing functional and evolutionary hypotheses

Several lines of evidence support the hypothesis that infant handling evolved as a non-adaptive by-product of a strong selection for mother-offspring bonding, and suggest that kin selection is a possible alternative explanation for the evolution of female infant-handling in primates.

Natal attraction: allomaternal care and mother–infant separations in wild bottlenose dolphins

Inexperienced females that never raised an infant were more likely to escort newborns than were parous experienced females, supporting the 'learning to parent' hypothesis.

Allomaternal vocal behavior in squirrel monkeys.

Early vocalizing to infants involves them in their first social exchanges and is probably performed by allomothers rather than mothers because the infant rides dorsally in this genus.

Natal Attraction in Adult Female Baboons (Papio cynocephalus ursinus) in the Moremi Reserve, Botswana

Testing several predictions derived from these hypotheses with data collected in a free-ranging group of baboons in the Moremi Reserve of Botswana suggests that infant handling might be the product of selection for appropriate maternal care if females who are highly responsive to infants are the most successful mothers.

Alloparental behavior in a captive group of spider monkeys (Ateles geoffroyi) at the Auckland zoo

The patterns of infant-other interaction in relation to the social structure and dispersal patterns of Ateles are discussed and the effects of age, sex, and reproductive status of alloparents are assessed.

Nonmaternal Infant Handling in Wild White-Headed Langurs (Trachypithecus leucocephalus)

The data, although limited in some analyses, are in line with the predictions of the learning-to-mother hypothesis, but do not support the female competition or alliance formation hypotheses.

Socialization of infant blue monkeys (Cercopithecus mitis stuhlmanni): Allomaternal interactions and sex differences

Investigation of differences in non-maternal social relationships of 12 infant blue monkeys in their first six months of life in a wild population found infants were spatially well integrated into the core of the group, associating with most available adult and large juvenile partners.

Exchange of Grooming for Allomothering in Female Patas Monkeys

Invest and reciprocity by unaffiliated (rarely grooming) non-kin females tended to occur most promptly, in accord with the hypothesis that fairness of reciprocity can be easier assessed if reciprocal acts occur immediately.



The Evolution of Allomothering Behavior Among Colobine Monkeys: Function and Opportunism in Evolution

It is hypothesized that, relative to the Cercopithecines, the dental morphology and digestive system of the Colobines produced food-acquiring and food-processing advantages that reduced intragroup feeding competition and, concomitantly, reduced the importance of status differences between females.

Lactation and care for unrelated infants in forest‐living ringtailed Lemurs

An adult female ringtailed lemur (Lemur catta) known not to have been pregnant showed spontaneous lactation in response to twin infants born to an unrelated female, and like the two maternal females, frequently attacked unfamiliar immigrating adult males when the males approached the infants.

Determinants of fecundity and reproductive success in captive vervet monkeys

High‐ranking females contributed the most to the high rate of fecundity, with significantly shorter interbirth intervals, more births per female year, and more surviving infants compared to low‐ ranking females.

Reproductive and social behavior of marmosets with special reference to captive breeding.

Although not all individuals of all species might show this behavior, it seems to be widespread enough to be an important factor in breeding efficiency and might figure in some of the infanticides observed by us and other authors.

Aunts and Mothers: Adaptive Implications of Allomaternal Behavior of Nonhuman Primates

Selective consequences of infant kidnapping and aunting-to-death are examined, and a hypothesis is suggested concerning the adaptive significance for mothering of allomothering.
