Adaptive Significance of Platyrrhine Patrilocal Structure

1.新大陆猴父系社会结构的研究1）我们对毛猴进行了按年代的社会结构研究（Lagothrix lagotricha）和蜘蛛猴已被证实有父系社会的人，通过个人识别和习惯化的方法。2）我们收集了一个习惯性长毛猴群体和一个习惯性蜘蛛猴群体中所有个体之间社会关系的详细数据3）观察了几例毛猴和蜘蛛猴幼猴从纳塔尔群迁移到种群的过程; 4）对吼猴的社会结构进行了时间顺序研究（Alouatta seniculus）和卷尾猴（Cebus apella）与具有父系社会的毛猴和蜘蛛猴相比，已被证实具有母系社会。我们观察了几个案例，如何年轻的雄性吼猴和卷尾猴移民， ...更多信息 采集并鉴定了毛猴和蜘蛛猴的所有食用植物.对具有母系社会的猕猴栖息地进行了研究。1）调查了猕猴的微地形、植物分布和森林结构与其游牧和食物斑块的关系。2）通过树木普查定量地了解了森林结构的变化。3）调查了洪水干扰与先锋植物种群结构的关系。本文对黄貂鱼的种子传播机制进行了研究，并对黄貂鱼种子在毛猴、蜘蛛猴和凤冠鹦鹉之间的传播方式进行了比较研究7）对蜘蛛猴主要食物棕榈科植物（多果棕榈、异根苏铁、三角叶棕榈、油棕）的物候进行了研究。少

1. Studies on the patrilocal social structure among New World Monkeys1) We carried out the chronological social structure of woolly monkeys (Lagothrix lagotricha) and spider monkeys (Aleles belzebuth) who had been confirmed to have patrilineal societies, by methods of individual identification and habituation.2) We collected detailed data on the social relationships among all individuals of one habituated woolly monkey group and one habituated spider monkey group at resting trees and feeding trees.3) We observed several cases of how young females of woolly monkeys and spider monkeys emigrated from natal group and immigrated the group.4) We carried out the chronological social structure of howler monkeys (Alouatta seniculus) and capuchin monkeys (Cebus apella) who had been confirmed to have matrilineal societies in comparison with woolly monkeys and spider monkeys who have patrilineal societies.5) We observed several cases of how young males of howler monkeys and capuchin monkeys emigra … More ted from natal group and immigrated the group.6) We collected and identified all of food plants of woolly monkeys and spider monkeys.2. Studies on the habitats of monkeys who have ptrilineal societies.1) We investigated the micro-landform, plant distribution and forest structure in relation to monkeys nomadism and food patches.2) We quantitatively understood the change of forest structure by tree census.3) We investigated the relation between flood disturbance and the population structure of a pionieer plant, Tessaria integrifolis.4) We observed the late stage of rhizome development in a clump of Pharus virescens.5) We investigated seed dispersers of Pharus virescens.6) We comparatively investigated the mode of seed dispersion among woolly monkeys, spider monkeys and Curassows (Crax salvini : one kind of terestial largebind).7) We studied the phenology of some species of Palmae (Jessenia polycarpa, Socratea exorrhiza, Iriartea deltoides, Euterpe precatoria), fruit of which were main foods of spider monkeys.
