断奶幼仔的供给是绒猴和绢毛猴合作饲养系统的重要组成部分。幼马立克次体从所有成年组成员那里获得相当大比例的食物，而大多数其他灵长类动物的幼马立克次体只通过乞讨从母亲那里获得食物。我们进行了纵向研究，通过他们的第一年的生活在两个巴西储备供应21年轻的野生金狮绢毛猴。青少年预计将经历更高的供应率在网站上与成熟的森林（假定的祖先栖息地），并在成熟的森林保护区内的首选栖息地的比例较高的领土。关键措施的供应没有显着不同的栖息地类型。少年乞求食物的速率在不同的栖息地非常相似，而栖息地对少年获得食物的速率的影响很小，并且在不同的年龄组。储备之间最显着的差异是：成年人对食物转移尝试的抵抗力较低，食物转移前的食物提供电话更频繁，猎物供应的比例更高，在早期演替阶段的森林占主导地位的储备。在成熟的森林保护区，乞讨成功的年轻少年协变积极的首选栖息地。而不是公开的照顾者后代的冲突，青少年和成年人之间的信息反馈回路似乎驱动供应的变化，青少年成熟。资源丰富的直接措施，需要帮助澄清森林演替阶段影响供应的机制。
Provisioning weaned young is an important part of the cooperative rearing system of marmosets and tamarins (family: Callitrichidae). Juvenile callitrichids receive a substantial proportion of their diet from all adult group members, whereas juveniles of most other primate species only receive food from the mother infrequently via scrounging. We conducted a longitudinal study of provisioning to 21 young wild golden lion tamarins through their first year of life in two Brazilian reserves. Juveniles were predicted to experience higher provisioning rates at the site with mature forest (the presumed ancestral habitat) and in territories that contained a higher proportion of preferred habitat within the mature forest reserve. Key measures of provisioning did not differ substantially between habitat types. The rates at which juveniles begged for food were very similar across habitats, while the influence of habitat on the rates at which juveniles received food was small and varied across age groups. The most pronounced differences between the reserves were: adult resistance to food-transfer attempts was less frequent, food-offering calls before food transfer were more frequent, and the proportion of prey provisioned was higher in the reserve in which earlier successional-stage forest predominated. Within the mature forest reserve, begging success of young juveniles covaried positively with preferred habitat. Rather than overt caretaker–offspring conflict, an information–feedback loop between juveniles and adults appears to drive provisioning changes as juveniles mature. Direct measures of resource abundance are needed to help clarify the mechanisms by which forest successional stage influences provisioning.
