Cross-fostering between two species of marmosets (Callithrix jacchus and Callithrix penicillata)

Abstract

Cross-fostering technique can be defined as adoption of infants by adults of other species. This phenomenon is poorly investigated because very young animals have few opportunities to interact peacefully with non-conspecific adults, either in captivity or in natural conditions. This study describes the induction of cross-fostering in captivity between white tufted-ear (Callithrix jacchus) and black tuftedear marmosets (Callithrix penicillata). We conclude that this technique can be very useful for preserving the life of rejected by parents or orphan infants, mainly in the case of species with low reproduction rate in captivity or those threatened by extinction, as well for investigating the environmental effects on the typical behavior of species (courtship, food preference, vocalization patterns, e.g.).

Comparison between sex and age class on some physiological, thermal, and hematological indices of the cerrado's marmoset (Callithrix penicillata)*

“…However, emotional reactivity differences between common marmoset and cerrado's marmoset is a possibility to investigate. In a comparison of parental behavior, Guerra and co‐workers [12] suggested a higher emotional reaction on cerrado's marmoset than in the common marmoset. To our knowledge, emotional and physiological differences between common marmoset and cerrado's marmoset was not finely discriminate yet.…”

“…Interestingly, the RTT of juveniles was significantly smaller than RTT of adults, probably reflecting a difference in the regional irrigation and metabolism on the tympanic membrane [1, 4, 17, 18, 24]. The right cerebral hemisphere concentrates more related areas to the control and expression of emotions [6, 12]. In this case, the difference found among adults and juveniles on the RTT, presumably can be a result from different emotional reactivity of juveniles to capture stress and handling.…”

The marmoset monkey as a model for visual neuroscience

“…Their capacity make detour reaches around visible obstacles is adversely affected by damage to the prefrontal cortex (Wallis and Roberts, 2001; Walker et al, 2006). While individual marmosets may show right or left hand preferences, no dominant hand preference is evident across the wider population (Hook-Costigan and Rogers, 1994; Guerra et al, 1997; Hook and Rogers, 2008). For those with hand preferences, the preferred hand often depends on their postural position (Hook and Rogers, 2008; Hashimoto et al, 2013).…”

Cross‐genus adoption of a marmoset (Callithrix jacchus) by wild capuchin monkeys (Cebus libidinosus): case report

“…Maestripieri [2001] proposed that adoption of an unrelated infant is an evolutionary maladaptive consequence of mechanisms selected to promote mother-infant bonding. Indeed, adoption has even been achieved between different species of primates in captivity (Macaca mulatta and M. fuscata [Owren & Dieter, 1989], and Callithrix jacchus and C. penicillata [Guerra et al, 1998]). In those cases it was pointed out that crossfostering should be done between related species in order to avoid incompatibilities in milk composition and parental behavior [Guerra et al, 1998].…”
