项目摘要

Few aspects of human and non-human primate behavior are so intriguing as the intense care of infants by fathers, and nowhere among primates is paternal care more extensive than among owl monkeys. Owl monkeys are small, arboreal neotropical primates who live in monogamous groups with only one reproducing male and one reproducing female. The father is the main provider of infant care, transporting, sharing food and grooming the infant more than the mother; paternal investment is exceptionally strong and apparent in this species. Research focused on these primates should inform our understanding of the functional and evolutionary significance of this distinctive reproductive system.Since 1996, the Owl Monkey Project of Argentina has evaluated hypotheses to explain the evolution of social monogamy and infant care in primates. In this study, a team of investigators and students from the US and Argentina will evaluate the hypothesis that the functional significance of paternal care in owl monkeys relates to the bioenergetic benefits that the parenting couple accrues from the father's assistance. Taking a novel approach that combines research on both captive and wild owl monkeys, the team will gather data on foraging and activity patterns, body mass changes, energy intake, and hormones. The relevance of the study, which has the potential to transform how energetics are measured in the field, lies in contributing to the understanding of the role of males in societies that are characterized by a strong bond between partners and shared parental duties. The study will expand the broad impacts of the Owl Monkey Project. As the only long-term research program on any mammal species in the Argentinean Gran Chaco, the project has multiplying effects on the conservation of this ecosystem and its fauna. It also promotes the development of young scientists and the discipline of biological anthropology through the participation over the years of more than 270 students (55% females, 45% males) from the US, Argentina and 14 other countries; student training and involvement in the research will further augment this strong record.

人类和非人类灵长类动物行为的几个方面是如此吸引人，因为父亲对婴儿的强烈照顾，而灵长类动物中的无处可比猫头鹰猴子更广泛。猫头鹰猴子是小的树木新热带灵长类动物，他们生活在一夫一妻群中，只有一只繁殖男性和一只繁殖女性。父亲是婴儿护理，运输，共享食物和修饰婴儿的主要提供者，而不是母亲。父亲投资在该物种中异常强大且明显。专注于这些灵长类动物的研究应告知我们对这种独特的生殖系统的功能和进化意义的理解。1996年，阿根廷的猫头鹰项目评估了假设，以解释灵长类动物中社会一夫一妻制和婴儿护理的进化。在这项研究中，来自美国和阿根廷的研究人员和学生团队将评估以下假设：猫头鹰猴子中父亲护理的功能意义与育儿夫妇从父亲的帮助中获得的生物能益处有关。该团队采用一种结合了圈养和野生猫头鹰猴的研究的新方法，将收集有关觅食和活动模式，体重变化，能量摄入和激素的数据。这项研究的相关性有可能改变现场衡量能量学的方式，这在于有助于理解男性在社会中的作用，这些社会的作用为以伴侣和共同的父母职责之间的牢固联系。该研究将扩大猫头鹰猴项目的广泛影响。作为阿根廷格兰查科（Gran Chaco）中任何哺乳动物物种的唯一长期研究计划，该项目对该生态系统及其动物的保护具有多重影响。它还通过来自美国，阿根廷和其他14个国家的270多名学生（55％的女性，45％的男性）的参与来促进年轻科学家的发展和生物人类学的学科；学生培训和参与研究将进一步增强这一强大的记录。
