“…Together with the strong effect of proactive food sharing on OT, this indicates that OT levels during periods of intense infant-care do not simply result from physical contact, as suggested for prolactin (Mota et al, 2006). Rather, OT may be involved in the motivational regulation of infant-care, which is also consistent with stimulating effects of exogenous OT-administration on maternal (Kendrick et al, 1987;Pedersen et al, 1994) and non-maternal (Bales et al, 2007;Madden and Clutton-Brock, 2011;Saito and Nakamura, 2011) care-taking in mammals.…”

“…Positive evidence related to non-maternal care exists for example for tamarin fathers, who show changes of testosterone, estradiol, and glucocorticoid levels in the pre-partum period as well as during infant-care, possibly preparing males for the impending birth and parenting role (Ziegler and Snowdon, 2000;Ziegler et al, 2004;Ziegler et al, 1996). Prolactin is also positively linked to infant-care in marmoset fathers and helpers (Dixson and George, 1982;Mota et al, 2006;Mota and Sousa, 2000;Roberts et al, 2001, Schradin andAnzenberger, 2004;Schradin et al, 2003), but these studies suggest that prolactin increases in response to infant-contact and -carrying rather than promoting such behaviors based on motivation-stimulating effects. Accordingly, experienced marmoset fathers could express normal paternal care even if prolactin was suppressed (Almond et al, 2006).…”

Oxytocin is associated with infant-care behavior and motivation in cooperatively breeding marmoset monkeys

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.

Male parenting and response to infant stimuli in the common marmoset (Callithrix jacchus)

Callithrix jacchus infants are raised in complex family environments where most members participate in rearing the young. Many studies examining male parental behavior have focused on the carrying of infants with observations made within the family context. However, interference from family members can make it difficult to assess the father's motivation to care for infants. Our goals were to develop a testing paradigm for determining an individual's response to infant stimuli separate from family influences, compare a male's motivation to respond to an infant stimulus outside the family with his paternal behavior within the family, to compare responses to infant stimuli of parentally experienced versus inexperienced males and finally to develop a reproducible and standardized method of testing male responsiveness to infant stimulus that could serve to evaluate hormonal manipulations. Fifteen experienced common marmoset fathers were evaluated using three different measures of parental behavior: (1) instantaneous scan sampling, (2) continuous focal sampling in the family, and (3) continuous focal sampling of males presented with four infant stimuli: familiar and unfamiliar infants, familiar and unfamiliar infant vocalizations. Six parentally inexperienced males (non-fathers) served as controls. Males that carried the most in the family were typically the same males that responded most to the infant vocalization tests. Experienced fathers did not differ in their latency to enter the stimulus cage for any of the four infant stimuli response tests while inexperienced males took significantly longer to enter the stimulus cage. In addition, fathers expressed a greater frequency of infant-directed behavior than did the inexperienced males during the unfamiliar infant and unfamiliar vocalization tests. These studies show that experienced male marmosets are highly motivated to interact with infant stimuli and that there is interindividual variability in response to infant vocalizations. Testing males outside of the family allows for a clear assessment of male's interest in infant stimuli in both parentally experienced fathers and inexperienced males.

“…Biologists from several fields are increasingly concerned about animal welfare. This is because, as well as the growing importance of ethical issues, the conditions in which animals are maintained may affect results obtained in behavioural, physiological, chronobiological and pharmacological studies, among others [Abbott et al, 2003;Barbosa and Mota, 2004;Mota et al, 2006;Gonçalves et al, 2007].…”

“…They are an important resource in scientific research and are studied in groups [Mota et al, 2006;Barbosa and Mota, 2009] and reproductive pairs [Barbosa and Mota, 2004;Ziegler et al, 2005]. Despite the importance of social interaction for this species, in some studies the animals are kept isolated [Cunha et al, 2006;Chen et al, 2009;Yamaguchi et al, 2010], leading to a negative impact on the health and welfare of these animals.…”

The daily distribution of autogrooming was evaluated in adult marmosets submitted to different illumination intensities in the light phase of the light-dark cycle. Autogrooming and locomotor activity were monitored and the faecal cortisol level assessed as a stress indicator. The distribution of autogrooming showed two distinct tendencies: when the light intensity varied from 500 to 200 lux, a slight increase in frequency and duration was observed, while a significant decrease in both variables occurred at 10 lux. Varying light intensities did not inhibit rhythm synchronization. The daily profile of autogrooming was mainly unimodal with an acrophase in the first half of the light phase. Faecal cortisol levels tended to increase in animals submitted to 100 and 10 lux, but these results are not conclusive. We suggest keeping captive marmosets in light intensities of at least 200 lux in the light phase, allowing animals to maintain autogrooming levels in order to reduce the discomfort caused by captivity and isolation.
