“…First, we investigated whether urinary OT levels increased immediately after infant-birth in mothers and other adult care-takers, which would be consistent with the neuroendocrine priming hypothesis (Pryce, 1993). Based on OT functions in mammalian birth (Kendrick, 2000;Landgraf et al, 1983;Nissen et al, 1995) and lactation (Uvnäs-Moberg et al, 2001), we expected OT levels of breeding females to be elevated after birth and during lactation until infant-weaning.…”

The neurohormone oxytocin (OT) is positively involved in the regulation of parenting and social bonding in mammals, and may thus also be important for the mediation of alloparental care. In cooperatively breeding marmosets, infants are raised in teamwork by parents and adult and subadult non-reproductive helpers (usually older siblings). Despite high intrinsic motivation, which may be mediated by hormonal priming, not all individuals are always equally able to contribute to infant-care due to competition among care-takers. Among the various care-taking behaviors, proactive food sharing may reflect motivational levels best, since it can be performed ad libitum by several individuals even if competition among surplus care-takers constrains access to infants. Our aim was to study the link between urinary OT levels and care-taking behaviors in group-living marmosets, while taking affiliation with other adults and infant age into account. Over eight reproductive cycles, 26 individuals were monitored for urinary baseline OT, care-taking behaviors (baby-licking, -grooming, -carrying, and proactive food sharing), and adult-directed affiliation. Mean OT levels were generally highest in female breeders and OT increased significantly in all individuals after birth. During early infancy, high urinary OT levels were associated with increased infant-licking but low levels of adult-affiliation, and during late infancy, with increased proactive food sharing. Our results show that, in marmoset parents and alloparents, OT is positively involved in the regulation of care-taking, thereby reflecting the changing needs during infant development. This particularly included behaviors that are more likely to reflect intrinsic care motivation, suggesting a positive link between OT and motivational regulation of infant-care.

“…The close association between the young and their mothers, particularly during pregnancy and nursing, allows them to share a physiological environment that might be essential both to maintenance of the fetus and initiation of mother-infant interaction after parturition. A regulation model of maternal behavior in marmosets and tamarins was developed by Pryce (1993) and includes the hormones that control pregnancy and parturition, genital stimulation during parturition, previous experience with infants at or after it, and the synergistic interaction of these three factors at birth. Among the factors mentioned above, previous experience has an important role in establishing effective mothering (rats: Rosenblatt, 1967;Fleming and Sarker, 1990;sheep: Poindron and Le Neidren, 1980;Lévy and Poindron, 1987;nonhuman primates: Holman and Goy, 1995), where recognition of the infant as a familiar individual is a way of preventing avoidance behavior or even infanticide as reported for male rodents (Huck et al, 1982;Elwood and Kennedy, 1991).…”

“…For fathers, their participation in infant care might increase their access to the breeding female (Price, 1990). For older offspring, it might improve their infant care skills by gaining experience with siblings (Hoage, 1978;Epple, 1978;Tardif et al, 1984;Cleveland and Snowdon, 1984;Pryce, 1988Pryce, , 1993Baker and Woods, 1992;Snowdon, 1996;Sousa et al, 1997), increase the likelihood of inheriting a breeding position by staying in the social group (Goldizen and Terborgh, 1989;Ferrari and Diego, 1992;Baker et al, 1993), especially in saturated areas, since breeding opportunity outside the group may be limited and increase inclusive fitness gains through caring for and improving the survival of relatives (Garber et al, 1984). On the other hand, the costs for fathers and older offspring related to caring behavior seem to be the energetic cost of infant transport during traveling (Kirkwood and Underwood, 1984;Goldizen, 1987;Price, 1992;Sanchez et al, 1999), the increased risk of predation leading to the use of anti-predator strategy by caretakers (Caine, 1993;Tardif, 1994Tardif, , 1997Snowdon, 1996), and reduced foraging time during infant transport (Goldizen, 1987;Price, 1992;Digby and Barreto, 1996).…”

Hormonal changes related to paternal and alloparental care in common marmosets (Callithrix jacchus)

The physiological mechanisms of parental and alloparental care in cooperatively breeding nonhuman primate species such as the common marmoset (Callithrix jacchus) are poorly known. In this study, we examined prolactin and cortisol plasma levels of fathers and older offspring of both sexes, with and without previous experience in infant carrying, around parturition and during infant carrying. Blood samples were collected from fathers and older offspring and prolactin and cortisol were measured by RIA and EIA, respectively. Prolactin levels of both caretakers were not influenced by infant's birth, previous experience or proximity to parturition. However, prolactin levels increased in both caretakers while in physical contact with infants and also with the number of infants being carried in older offspring. These findings suggest that increased prolactin seems to be mainly due to physical effort rather than a physiological trigger of paternal and alloparental care in common marmosets. Cortisol levels were higher for experienced fathers shortly before parturition which could act to reinforce affiliative bonds between breeding males and females at this time or in the ability of males to detect the proximity of the parturition or both.

Several New World monkey species experience high rates of infant mortality in captivity, and parental failure in the form of infant neglect and abuse is often regarded as one of the leading causes of this problem. We explored a large archival database to assess environmental, familial, and biological variables identified as significant for parental success in previous studies of captive tamarins, through several generations and across several dozen pedigrees. Using a stepwise multiple regression analysis we developed a model including the fewest variables able to identify statistically significant predictors of infant outcome. We found that seven independent variables could predict infant outcome in the colony. The most important appeared to be the presence of helpers with whom parents could share infant carrying. Mother's experience and litter size were two other variables that contributed to a significant extent to explaining parental failure. Moreover, the model showed that there is a measurable contribution to infant outcome due to the health status of both parents. Finally, we found a distinct role for mothers and fathers, and that parental failure follows different patterns for abuse and rejection.
