Dissertation Research: Social Organization and Mating Systems of Saguinus Mystax on Padre, Isla, Peru

这项研究项目将调查秘鲁亚马逊Padre Isla上的一群Sanguinus mystax，或称络腮胡罗望鱼的社会组织。长期以来，罗望子一直被认为是不同寻常的灵长类动物，因为它具有一些罕见的社会性特征，例如只有一只雌性才能繁殖，有生双胞胎的倾向，以及雄性广泛参与婴儿护理。然而，直到最近，人们对它们在野外的社会行为知之甚少；所有关于社会组织的推论都是基于对圈养动物的观察。在野外工作过程中，预备役人员将记录部队的组成，并分析个人之间的互动模式。然后，学生将测试父母投资理论对群体组成、交配系统和个人间行为的影响。对不同灵长类物种的研究对于人类经历的生物学斑点是有意义的。灵长类动物的研究为研究人类起源提供了一个比较的背景。有关马鞭毛虫的信息特别重要，因为它提供了关于雄性照顾婴儿的信息：成年雄性和年轻雄性之间的照顾关系代表了人类和类人猿社会组织之间预先发现的差异。

This research project will investigate the social organization of a population of Sanguinus mystax, or mustached tamarins, on Padre Isla in the Peruvian Amazon. Tamarins have long been recognized as unusual primates due to a number of rare sociosexual traits, such as the restriction of breeding to a single female, the tendency to bear twins, and the extensive participation of males in infant care. Until recently, however, little was known of their social behavior in the wild; all inferences of social organization were based on observations of captive animals. During the course of fieldwork the reseracher will document the composition of troops and analyze patterns of interindividual interaction. The student will then test the implications of parental investment theory with regard to group composition, mating systems and interindividual behavior. Research on different primate species is informative with regard to the biological spects of the human experience. Primate studies provide a comparative context for investigating human origins. Information on callitrichids is especially important since it provides information on male care of infants: care- giving relationships between adult males and young represent a prfound difference between human and great ape social organization.
