Familiarity may buffer the adverse effects of relocation on marmosets (Callithrix kuhlii): Preliminary evidence

Abstract 10.1002/zoo.20019.abs The relocation of exotic species is increasingly crucial for the proper management of captive populations. We investigated the effects of relocation on urinary cortisol levels and proximity behavior in four Wied’s marmosets (Callithrix kuhlii). Two of the relocated marmosets constituted a well-established pair, whereas two (the newly established pair) were introduced when they […]

Vitamin D intakes by cotton-top tamarins (Saguinus oedipus) and associated serum 25-hydroxyvitamin D concentrations

Abstract 10.1002/(SICI)1098-2361(1999)18:63.3.CO;2-Z Rickets and osteomalacia have been reported frequently in captive callitrichids. Some have assumed that these conditions are a consequence of unmet, unusually high requirements for vitamin D and that these high requirements are characteristic of all New World primates. As a consequence, certain commercial diets formulated for New World primates contain such high […]

An assessment of gum-based environmental enrichment for captive gummivorous primates

Abstract In the wild, many primates consume gums exuded from trees, and many species are gum specialists. In spite of this, few data exist concerning gum feeding in captivity. Using a web-based survey of 46 zoos in 12 countries, we evaluated the extent to which zoos feed gum to primates. We found that although callitrichids […]

Stability of breeding and non-breeding groups of golden-headed lion tamarins (Leontopithecus chrysomelas)

In Callitrichid primates, offspring remain in their natal group beyond the age of sexual maturity, increasing the group’s inclusive fitness by cooperatively rearing their siblings. Contraception of the dominant female in these groups may alter the associated costs and benefits of this cooperative rearing in such a way that offspring themselves attempt to breed when […]
