Maternal caretaking and transport of dead infants are widespread among nonhuman primates, having been reported in numerous species of monkeys and apes. By contrast, accounts of such behaviors toward dead juveniles are scarce. Here, we describe responses by the mother and other group members to the death of a juvenile in a wild, multi-level group of Sichuan snub-nosed monkeys (Rhinopithecus roxellana). Following the juvenile’s fatal accident, his mother transported and cared for the corpse for four days. Immature monkeys belonging to the same one-male unit, and some individuals from other social units also showed interest in and tended the corpse. Comparisons of this case with those involving the deaths of infants and an adult female in the same population highlight possible effects of physiological, psychological and emotional factors in primate thanatological responses, and provide an additional perspective on the origin and evolution of compassionate acts.

Parental reactions to a dying marmoset infant: conditional investment by the mother, but not the father

The reproductive costs of cooperatively breeding callitrichid mothers are remarkable, and they have to rely on fathers and other group members to raise their offspring. Consequently, maternal responsiveness to and investment in infants tends to be conditional, and especially sensitive to infant cues and signals of vigour. Since fathers do not bear the same excessive reproductive costs, their threshold to invest in a dying immature may be lower than in mothers. We present an anecdotal report of reactions of a first-time breeding pair of captive common marmosets (Callithrix jacchus) to their dying infant. We found a male bias in all interactions with the dying infant that did not show typical cues of infant vigour. These results show that the dying infant elicited more investment by the father than the mother. Because of this conditional maternal investment, infants of cooperatively breeding primates may be under selection to advertise their viability, in particular to their mothers.

“…The most extensive array of post-mortem behaviours has been described in the primate order; these include observations from captivity and the wild. In Old World monkeys, such observations include yellow baboons (Papio cynocephalus [Altmann, 1980]), chacma baboons (Papio ursinus [Carter et al, 2020]), Japanese macaques (Macaca fuscata [Sugiyama et al, 2009;Takeshita et al, 2020]), Sichuan snub-nosed monkeys (Rhinopithecus roxellana [Yang et al, 2022]), Indian langurs (Presbytis entellus [Jay, 1962]), Hanuman langurs (Semnopithecus entellus [Sharma et al, 2011]), Geladas (Theropithecus gelada [Fashing et al, 2011]), Zanzibar red colobus (Piliocolobus kirkii [Georgiev et al, 2019]), bonnet macaques (Macaca radiata [Das et al, 2019]), and lion-tailed macaques (Macaca silenus [Das et al, 2019]); in New World monkeys, these species include blonde capuchins (Sapajus flavius [Andrade et al, 2020]), brown capuchins (Sapajus apella [Trapanese et al, 2020]), and northern muriquis (Brachyteles hypoxanthus [Freire Filho et al, 2022]). Post-mortem behaviours have also been observed in several ape species: chimpanzees (Pan troglodytes [Biro et al, 2010;Cronin et al, 2011;Matsuzawa, 1997;Soldati et al, 2022;Van Lawick-Goodall, 1968]), Sumatran orang-utans (Pongo abelii [Dellatore et al, 2009]) and gorillas (Gorilla beringei [Warren & Williamson, 2004]).…”

Mother-infant relationships in wild Guinea baboons (Papio papio)

During infancy, primates are heavily dependent on their mothers for nursing, transport, and thermoregulation, but also benefit from associating with their mothers for protection and social support. Furthermore, the mother acts as a role model for social learning, facilitates the interaction with the physical environment and the integration into a broader social network. The repeated interactions and reciprocity between mother and infant, along with the time that they spend together, lead to the formation of the mother-infant bond, which is typically recognised as the strongest social bond in the life of primates. The relationship between mothers and infants is dynamic, and they typically spend most of the time in contact and in close proximity just after infants have been born, and mothers frequently nurse and carry their infants, but soon enough time in contact, carrying, and nursing progressively decreases, and proximity increases as mother and infant move along infancy.Weaning is a period typically marked by behaviours of maternal rejection and increase of distance between mother and infant promoted by the mother. By the end of infancy, individuals will be independent from their mothers, and will therefore be able to move and feed by themselves. Even though the mother-infant dependency decreases as infancy progresses, not all mothers behave in the same way towards their infants. The individual variation in maternal care is known as mothering style, and it can have marked differences in the fate of infants' development and survival. Generally, mothers that are more protective produce infants that have higher survival rates and grow faster, and infants of rejecting mothers have lower survival and grow slower, but reach independence earlier.The aim of this thesis was to investigate the mother-infant relationships in wild Guinea baboons living in the Niokolo-Koba National Park in Senegal. Guinea baboons live in a multi-level social organisation, with "units" at their base, several units forming "parties", and several parties grouping to form "gangs". Guinea baboons form strong social bonds with other males, have low levels of aggression, and show high spatial tolerance. Dispersal is female-biased, and even though females form linear and steep dominance hierarchies at the unit level, rank does not depend on kin. As a consequence of females transferring to other units, parties, or gangs, offspring might be left behind if a mother decides to disperse. Altogether, along with the fact that Guinea baboons live in a tolerant social system with regards to their social relationships, make Guinea baboons an interesting species to study mother-infant relationships. Summary 2In chapter 2 I provide a description of the behaviours between mothers and infants throughout infancy. I show that, similar to all primates, mothers and infants spend most of their time in contact and proximity in the early stages of infancy, and these behaviours, along with carry and nipple contact, decrease over time. Other behaviours, however, are very...
