“…Apparently, some infants are more attractive than others for males, but kinship is neither the primary nor a necessary cause for this attractiveness. Preliminary data from a field study on Alger ian Barbary macaques -where DNA finger printing was also used for paternity determi nation -support this view [26].…”

“…However, male care is also seen in some situations where males are unlikely to be related to the infants for whom they are caring. In Barbary macaques (Macaca sylvanus), paternity testing has shown that there is no direct relationship between the degree of male care found and paternity [18]. Further work is needed to investigate relationships between males and infants, as infants may be related to males in other ways e.g.…”

The amount of non-maternal care (allocare) found in primates varies greatly from species to species. Our paper examines this variation and focuses on possible reasons why mothers in some anthropoid primate species are prepared to relinquish their infants to other carers whereas others are not. We use data collected from the literature to test a number of hypotheses that attempt to explain the observed variation in non-maternal care. Analyses were carried out using comparative methods that control for the influence of both body size and phylogeny on life-history and ecological variation. The results support previous studies of both primates and other mammals in finding a clear link between the amount of allocare provided and female reproductive rates. Species with high allocare levels grow rapidly post-natally and wean their infants at a younger age (but at the same relative size) than species of the same body size with lower allocare levels. This early weaning allows high allocare species to support higher birth rates than low allocare species but does not result in earlier maturation. Our results, therefore, suggest that mothers allow non-maternal care of their infants in order to increase their own reproductive output. It is not clear whether such a strategy also benefits the infant, as we could find no link between the presence of allocare and early maturation (which would increase the infant’s reproductive output) or between allocare levels and infant survival (as measured by vulnerability to infanticide). This suggests that mothers and infants might come into conflict over transfer to other carers, as the benefits to the mother may not be accompanied by benefits to the infant. However, although mothers may benefit from allocare in some circumstances, they will not be expected to allow allocare if the costs are high (e.g. if there is a high risk to the infant).

“…In some baboon species, these preferences may reflect likelihood of paternity to some extent (Nguyen et al 2009;Moscovice et al 2010). In macaques male preferences for infants appear mostly unrelated either to paternity or to past mating (Paul et al 1992;Ménard et al 2001; but see Ménard et al 1992 andOstner et al 2013) but may reflect the male's social relationships with the mother and may be predictive of future mating opportunities (Ménard et al 2001; see also Smuts and Gubernick 2015). Males also choose the male partner in the bridging interaction nonrandomly (e.g.…”

“…They are seasonal breeders with a mating season in autumn and a birth season in spring (reviewed in Fooden 2007). Females mate with numerous males (Small 1990) and paternal kinship is not recognized (Ménard et al 2001;Kuester et al 1994; but see also Ménard et al 1992). Despite of the promiscuity selecting against male care for offspring (see van Schaik and Paul 1996), infants may spend exceedingly large proportions of the time being carried, cradled and groomed by males, whereas aggression or abuse by males are rare (e.g.…”

Triadic awareness predicts partner choice in male–infant–male interactions in Barbary macaques

et al. 2016

Social knowledge beyond one's direct relationships is a key to successful maneuvering of the social world. Individuals gather information on the quality of social relationships between their group companions, which has been termed triadic awareness. Evidence of the use of triadic awareness in natural contexts is limited mainly to conflict management. Here we investigated triadic awareness in wild Barbary macaques (Macaca sylvanus) in the context of bridging interactions defined as male-infant-male interactions whereby a male (actor) presents an infant to another male (receiver) in order to initiate an affiliative interaction with that male. Analyses based on 1,263 hours of focal observations on ten infants of one wild social group in Morocco supported the hypothesis that males use their knowledge of the relationship between infants and other adult males when choosing a male as a partner for bridging interactions. Specifically, (i) the number of bridging interactions among initiator-infant-receiver triads was affected by the strength of the infant-receiver relationship and (ii) when two males were available as bridging partners, a male was more likely to be chosen as the receiver the stronger his social relationship with the infant in comparison to the other available male was. This demonstrates that non-human primates establish triadic awareness also of temporarily rather dynamic infant-male relationships and use it in naturally occurring affiliative context. Our results contribute to the discussion about the mechanism underlying the acquisition of triadic awareness and the benefits of its usage and lend support to hypotheses linking social complexity to the evolution of complex cognition.
