Reciprocal benefits of allomothering for female vervet monkeys

  title={Reciprocal benefits of allomothering for female vervet monkeys},
  author={L. Fairbanks},
  journal={Animal Behaviour},
Abstract Allomothering, or care of the young by individuals other than the mother, was studied in captive groups of vervet monkeys, Cercopithecus aethiops sabaeus . The most frequently proposed hypotheses to explain caretaking by primate allomothers are (1) the mother benefits from the reduction in time and energy allocated to infant care, and (2) the allomother benefits by gaining maternal experience prior to the birth of her own first infant. Analysis of longitudinal data on behaviour and… Expand
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. Expand
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. Expand
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. Expand
Maternal protectiveness and response to the unfamiliar in vervet monkeys
Vervet monkeys (Cercopithecus aethiops sabaeus) show individual differences in approach‐avoidance behavior when faced with an unfamiliar and potentially threatening situation, and this result was designed to verify this result in a paradigm that experimentally varied maternal protectiveness through the introduction of new breeding adult males.

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. Expand

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. Expand
Natal Attraction in Adult Female Baboons (Papio cynocephalus ursinus) in the Moremi Reserve, Botswana
Mammalian females are strongly attracted to infants and interact regularly with them. Female baboons make persistent attempts to touch, nuzzle, smell and inspect other females’ infants, but do notExpand

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. Expand
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. Expand
Socialization of infant blue monkeys (Cercopithecus mitis stuhlmanni): Allomaternal interactions and sex differences
Summary An important part of the ontogeny of social mammals is the establishment of social relationships with non-mothers. Mothers may influence this socialization process, but other factors like theExpand


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.

Allomothering in a captive colony of Hanuman langurs (Presbytis entellus)
Allomothering may not have adaptive value of its own, but rather may have evolved as part of a total behavioral complex, and the apparent lack of improvement in the skills of juvenile allomothers casts doubt on the theory that allomatering is adaptive as a learning experience for allomathers.

Care and Exploitation of Nonhuman Primate Infants by Conspecifics Other Than the Mother
Publisher Summary This chapter shares the instances of care for infants by individuals other than the natural mother, and examines the instances of abuse of infants by males and females of variousExpand
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.

Social development during the first twenty weeks in the cotton-top tamarin (Saguinus o. oedipus)
Abstract Fourteen infant cotton-top tamarins from five captive family groups were studied during the first 20 weeks of life. We examined the roles of parents and of siblings of different ages asExpand
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. Expand

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. Expand
