It is suggested that a male who extends post-agonistic support to a female is significantly more likely to copulate with her.
Revisiting the possibility of reciprocal help in non-human primates
Interchange of Grooming and Agonistic Support in Chimpanzees
The relationship between prior grooming and support held true only for aggressor and not victim support and is consistent with behavior expected if chimpanzees anticipated the need for agonistic support and groomed their supporter the day before to increase the likelihood of support.
Evolutionary forces favoring intragroup coalitions among spotted hyenas and other animals
Overall, hyenas made flexible decisions regarding whether or not to intervene in fights, modifying their tendency to cooperate based on multiple types of information about their immediate social and ecological environments.
Grooming and agonistic support: a meta-analysis of primate reciprocal altruism
Findings suggest that grooming and agonistic support may have evolved as part of a system of low-cost reciprocal altruism, and highlight the potential of meta-analysis in tackling the study of behavioral phenomena characterized by low overall frequency and small effect sizes.
Assessing the sociability of former pet and entertainment chimpanzees by using multiplex networks
The sociability of atypically raised chimpanzees is investigated by constructing and analysing 4-layered multiplex networks of two groups of former pet and entertainment chimpanzees and this multiplex approach provides a more realistic framework giving detailed insight into the sociable of these chimpanzees and can function as a tool to support captive care management decisions.
Cooperation with closely bonded individuals reduces cortisol levels in long-tailed macaques
An intricate way in which the hypothalamic–pituitary–adrenal axis is involved in cooperation is shown, which shows the act of cooperating in itself led to a subsequent decrease in cortisol levels, but only when cooperating with closely bonded individuals.
Early life experience and alterations of group composition shape the social grooming networks of former pet and entertainment chimpanzees (Pan troglodytes)
It is concluded that the social grooming networks of former pet and entertainment chimpanzees are shaped not only by long-term effects such as early life experience, but also by short-termeffects such as alterations to group composition.
