项目摘要

This project is designed to investigate the social and ecological correlates of mating patterns and intergroup relationships in black-mantle tamarins, Saguinus nigricollis, in the lowland rainforest of eastern Ecuador. These small New World monkeys appear to be more monogamous than other tamarin species and, therefore, offer an excellent opportunity to test the hypothesis that variability in mating patterns is related to the costs of infant-rearing and the importance of cooperative breeding in tamarins. The study will use detailed behavioral observation of several populations to examine the ecological, reproductive, and social correlates of monogamy in black-mantled tamarins. In addition to its unusual mating patterns, this species is also distinguished by the fact that intergroup relationships are non-aggressive and neighboring groups may form polygroup associations. As a result, this species offers an opportunity to test the hypothesis that food competition between groups determines intergroup relationships, as well as hypotheses about the proximate causes, adaptive benefits, and social consequences of intergroup tolerance. This study will contribute to our understanding of the evolutionary and proximate relationships between cooperative breeding and mating patterns in New World monkeys and other cooperative breeding species.

该项目旨在调查厄瓜多尔东部低地雨林中黑幔狨猴 Saguinus nigricollis 的交配模式和群间关系的社会和生态相关性。这些小型新世界猴似乎比其他狨猴物种更实行一夫一妻制，因此，提供了一个绝佳的机会来检验以下假设：交配模式的变异性与婴儿饲养成本以及狨猴合作繁殖的重要性有关。该研究将利用对几个种群的详细行为观察来研究黑幔狨猴一夫一妻制的生态、生殖和社会相关性。除了其不寻常的交配模式外，该物种的特点还在于群体间关系是非攻击性的，并且相邻群体可能形成多群体关联。因此，这个物种提供了一个机会来检验群体之间的食物竞争决定群体间关系的假设，以及关于群体间耐受性的直接原因、适应性益处和社会后果的假设。这项研究将有助于我们了解新世界猴和其他合作繁殖物种的合作繁殖和交配模式之间的进化和近似关系。
