Cooperative infant care in which multiple individuals contribute to caring for a single offspring is thought to have played a key role in human evolution by reducing the energy mothers need to invest in their offspring. It can be challenging to disentangle the relationship between energetic costs and benefits of care provided by multiple individuals, and the study of this question can benefit from the examination of other species with similar forms of cooperative infant care. The simplest form, where infants receive care from only their mother and father, is called biparental care. This Doctoral Dissertation Research project measures energy expenditure related to infant care in primate species with biparental cooperative infant care. Behavioral data, movement data, and metabolic measurements of energy use during infant care are combined from wild and captive populations to investigate how these monkeys distribute the energetic costs of childcare responsibilities. The project supports long-term research and scientists at a field station and produces short bilingual videos to disseminate results.To quantify the relative investment of male and female parents in the care of their infants, this research combines behavioral data from both coppery titi monkeys with activity and energetics data. Coppery titi monkey mothers and fathers each specialize in some caring tasks: mothers nurse and fathers carry the infant. However, the extent of sex-based specialization for other caring behaviors, such as grooming and tolerated food theft remains unknown as does the energetic burden of these behaviors and any compensatory changes in the parents’ activity. Activity data will be collected throughout the entire period of infant care , andallows inferences about the energetic investment parents make during infant care to be made on both behavioral and physiological bases since the measures of energy use will be in the context of behavior and activity.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

多人合作照顾一个孩子被认为在人类进化中发挥了关键作用，因为它减少了母亲需要在孩子身上投入的能量。它可以是具有挑战性的解开能量成本和多个人提供的护理的好处之间的关系，这个问题的研究可以受益于其他物种与类似形式的合作婴儿护理的检查。最简单的形式，即婴儿只接受母亲和父亲的照顾，称为双亲照顾。这个博士论文的研究项目措施的能量消耗有关的婴儿护理灵长类动物物种与双亲合作的婴儿护理。行为数据，运动数据和代谢测量的能量使用在婴儿护理相结合，从野生和圈养种群，调查这些猴子如何分配精力充沛的成本育儿责任。该项目支持长期研究和一个野外工作站的科学家，并制作双语短片来传播研究结果。为了量化父母在照顾婴儿方面的相对投入，该研究结合了来自两种猕猴的行为数据以及活动和能量数据。猕猴的母亲和父亲都专门从事一些照顾任务：母亲哺乳，父亲携带婴儿。然而，基于性别的专业化程度的其他照顾行为，如梳理和容忍的食物盗窃仍然是未知的，这些行为的能量负担和任何补偿性的变化，在父母的活动。活动数据将在整个婴儿护理期间收集，由于能源使用的测量将在行为和活动的背景下进行，因此允许在行为和生理基础上对父母在婴儿护理期间所做的精力投入进行推断。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响进行评估，被认为值得支持审查标准。
