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.

据认为，多个人有助于照顾一个后代的合作婴儿护理，人们通过减少能量母亲需要投资其后代而在人类进化中发挥了关键作用。脱离了多个人提供的能源成本与护理收益之间的关系可能会受到挑战，并且对这个问题的研究可以受益于对具有类似形式的合作婴儿护理的其他物种的检查。最简单的形式，婴儿只从父母那里得到护理，被称为二胎护理。该博士学位论文研究项目衡量了具有双胎合作婴儿护理的灵长类动物物种中与婴儿护理有关的能量消耗。从野生和圈养的人群中结合了婴儿护理期间能量使用的行为数据，运动数据和代谢测量，以研究这些猴子如何分配育儿责任的能源成本。该项目支持现场站的长期研究和科学家，并制作了简短的双语视频以传播结果。为了量化男性和女性父母在照顾婴儿的相对投资，这种研究组合的行为数据来自两种铜质titi猴子，均具有活性和能量数据。铜蒂蒂·猴子的母亲和父亲分别专门从事一些携带任务：母亲护士和父亲携带婴儿。但是，基于其他关怀行为的基于性别的专业化程度，例如修饰和容忍食物盗窃，这些行为的能量燃烧以及父母活动的任何补偿性变化也是未知的。活动数据将在整个婴儿护理期间收集，并允许有关父母在婴儿护理期间提供的能源投资的信息，以便在行为和身体基础上进行，因为能源使用的措施将在行为和活动的背景下进行。该奖项反映了NSF的法定任务，并通过使用该基金会的知识绩效和广泛的影响来评估NSF的法定任务，并被认为是宝贵的支持。
