项目摘要

We carried out field studies for three years (1990-1992) in La Macarena of Colombia (1) on the chronological social structure of sympatrically living, seven New World monkey species and (2) on the architecture and dynamics of the neotropical forest as their habitats. Following results were obtained. As for the social structure,1. capuchins (Cebus apella) lived in a multi-male and multi-female group, and member transfer primarily occurred for males. Division of group occurred on the basis of kinship relation.2. Howler monkeys (Alouatta seniculus) basically lived in a one-male group, and member transfer occurred only for males. Infanticide when alphe-male of the group changed.3. woolly monkeys (Lagothrix lagotricha) and spider monkeys (Ateles belzebuth) lived in a multi-male and multi-female group, and had patrilineal societies, that is, member transfer primarily occurred for females.4. squirrel monkeys (Saimiri sciureus) lived in a multi-male and multi-female group, but males and females lived separately in their daily life.5. Titis (Callicebus moloch) and night monkeys (Aotus trivirgatus) lived in a family group (pair-group), but they segregated their habitats and daily activities completely. As for the neotropical forest,6.323 vascular plant species were identified among ca. 1,800 specimens collected in and around the study area.7. Vegetation mapping were carried out both from regional and stand-scale points of view.8. Vegetation succession at an expending meander bend was surveyed together with changes of micro-scale landform and physicochemical soil characteristics.9. Population dynamics of Tessaria integrifolia and Baccharis salicifolia, pioneer shrubs of Asteraceae, were analyzed on newly deposited riverine soils.10. co-evolutional significance of seed dispersal by monkeys and birds were studied in relation to their food habits and phenology of plant species.

我们在哥伦比亚的La Macarena进行了为期三年（1990-1992）的实地研究(1)，研究了7种新大陆猴的社会结构，(2)研究了作为它们栖息地的新热带森林的结构和动态。得到以下结果：就社会结构而言，1。卷尾猴（Cebus apella）生活在多雄性和多雌性的群体中，成员转移主要发生在雄性身上。群体的划分是在亲属关系的基础上发生的。吼猴（Alouatta seniculus）基本上生活在一个雄性群体中，成员转移只发生在雄性群体中。当群体中的雄性首领发生改变时，就会杀婴。长毛猴（Lagothrix lagotricha）和蜘蛛猴（Ateles belzebuth）生活在一个多雄性和多雌性的群体中，并且具有父系社会，即成员转移主要发生在雌性身上。松鼠猴（Saimiri sciureus）是一种多雄多母的群居动物，但雄性和雌性在日常生活中是分开生活的。夜猴（calicebus moloch）和夜猴（Aotus trivirgatus）生活在一个家庭群体中，但它们的栖息地和日常活动完全分开。在新热带森林中，在研究区内及周边采集的约1800份标本中，共鉴定出维管植物种类6.323种。从区域和林分尺度的角度进行了植被制图。对扩展曲流弯的植被演替、微尺度地貌和土壤理化特征的变化进行了调查。10.对菊科先锋灌丛荆芥（Tessaria integrgrifolia）和水杨花（Baccharis salicifolia）在新沉积的河流土壤上的种群动态进行了分析。研究了猴子和鸟类种子传播的共同进化意义，并与它们的食性和植物物候进行了联系。
