Patterns of infant handling and relatedness in Barbary macaques (Macaca sylvanus) on Gibraltar

  title={Patterns of infant handling and relatedness in Barbary macaques (Macaca sylvanus) on Gibraltar},
  author={Rolf K{\"u}mmerli and Robert Denis Martin},
Among papionin primates, the Barbary macaque (Macaca sylvanus) shows the most extensive interactions between infants and group members other than the mother. Two different types of interactions occur: (1) long-lasting dyadic interactions between a handler and an infant, and (2) brief triadic interactions between two handlers involving an infant. Previous investigations showed that infant handling by males is best explained as use of infants to manage relationships with other males. In contrast…

How do male interactions with infants affect mothers and infants in Barbary macaques (Macaca sylvanus)
In a provisioned group of macaques, mothers and infants do not appear to directly benefit from male infant handling but may pay a cost, while Mothers and infants may gain long-term benefits such as agonistic support, access to resources and earlier infant weaning from associated with males in the group.
Male Tibetan macaques'(Macaca thibetana) choice of infant bridging partners.
It is found that male infants were significantly preferred over females for bridging, but of three male infants in the group, only one was used by all males, while one male infant was used less often than expected.
Bridging may help young female Tibetan macaques Macaca thibetana learn to be a mother
The results of this study showed that subadult females initiated more bridging than adult females, and supported the ‘learning to mother’ hypothesis, suggesting that bridging among female intrasexual dyads is a multi-functional, complex and differential evolutionary process.
Do Adult Male Spider Monkeys (Ateles geoffroyi) Preferentially Handle Male Infants?
Support is provided for the hypothesis that adult males preferentially handle male infants as a strategy for fostering social bonds by observing patterns of infant handling among age–sex class dyads.
The Effect of Dominance Rank on the Distribution of Different Types of Male–Infant–Male Interactions in Barbary Macaques (Macaca sylvanus)
Using generalized linear mixed-effect models, it is found that males preferably initiated interactions with males that were dominant to them, but this effect was observed only for interactions initiated by the infant holder.
Triadic awareness predicts partner choice in male–infant–male interactions in Barbary macaques
Triadic awareness in wild Barbary macaques is investigated in the context of bridging interactions defined as male–infant–male interactions whereby a male presents an infant to another male in order to initiate an affiliative interaction with that male.
The male and female perspective in the link between male infant care and mating behaviour in Barbary macaques
Infant care from adult males is unexpected in species with high paternity uncertainty. Still, males of several polygynandrous primates engage in frequent affiliative interactions with infants. Two
Cooperation in wild Barbary macaques: factors affecting free partner choice
The results showed that Barbary macaques are able to pair up with a partner to cooperate using the apparatus, and high level of tolerance between monkeys was necessary for the initiation of successful cooperation, while strong social bond positively affected the maintenance of cooperative interactions.
Metarelational models: Configurations of social relationships
Beyond cognizing persons and social relationships, people also think about combinations of relationships: metarelational models (MeRMs). If relationships are words, then MeRMs are syntax; if

The sociobiology of male–infant interactions in Barbary macaques, Macaca sylvanus
Abstract Unlike most Old World monkeys, male Barbary macaques frequently associate with and care for infants shortly after birth. Three functional hypotheses have been proposed to explain male–infant
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.
Male‐infant relationships in semifree‐ranging Barbary macaques (Macaca sylvanus) of affenberg salem/FRG: Testing the “male care” hypothesis
It is suggested that certain mothers prevented early contacts between their infants and males so that the observed preferences for certain infants were also a result of easier access to them, and results suggested that males interacted with infants for their own benefit.
Interactions Between Males and Unweaned Barbary Macaques: Testing the Agonistic Buffering Hypothesis
The results confirmed the importance of a baby's presence in the dynamics of male-male interaction and justify the use of the term 'agonistic buffering'.

A new hypothesis is tested, that IH tests social bonds between adult females, using data on a group of wild white-faced capuchins, and the nonadaptive, learning-to-mother, reciprocity, harassment and alliance-formation hypotheses are unsupported.
Infant handling and mortality in yellow baboons (Papio cynocephalus): evidence for female reproductive competition?
Examination of negative and positive infant handling behavior in 24 free-ranging yellow baboon infants studied over a 5-year period in Mikumi National Park, Tanzania shows that high level of negative infant handling was a significant predictor of infant mortality by age 3 months.
Male and Female Reproductive Success in Macaca sylvanus in Gibraltar: No Evidence for Rank Dependence
It might be concluded either that a correlation between social rank and reproductive success is generally absent in Barbary macaques or that artificially favorable environmental conditions in Gibraltar preclude any correlation.

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
Is male-infant caretaking related to paternity and/or mating activities in wild Barbary macaques (Macaca sylvanus)?
It was found that mating success was not related to paternity, so males could invest in infants that they had not sired, and caretaking of non-offspring was actually observed, leading to comprehensive rejection of the paternal investment hypothesis in Barbary macaques.
