The Ecology and Behavior of Mantled Howling Monkeys

这项研究是一个长期项目的继续， 在1972年，为了研究生态，行为和人口统计学， 披着斗篷的吼猴 研究的目的是 研究是什么影响了密度、分散度、繁殖 成功和猴子的食物选择。 生态和 行为数据将收集个人生活（1）在 不同的生境;（2）不同的人口密度;以及， (3)在不同规模的社会群体中。 的比较分析 结果将被用来检验各种假设 社会生物学理论。 例如，一个假设是， “小组成员与亲戚分享资源”比与 非亲属。 研究可以集中在个人 因为350只吼猴中的大多数 都有独特的标记和可识别性。 长期和 对标记动物的多学科研究可以提供 关于生活史变量和亲属关系的信息， 这些因素可能会随着时间的推移而改变。 许多非人类灵长类动物要么受到威胁，要么受到高度威胁。 濒临灭绝，并试图保护最 濒临灭绝 在这方面，一个强有力的工具是数学 建模，模型必须用长期数据进行测试 像这样的人口统计学研究

This research is the continuation of a long-term project, begun in 1972, to study the ecology, behavior, and demography of mantled howler monkeys. The objectives of the study are to examine what influences density, dispersion, reproductive success, and food selection of the monkeys. Ecological and behavioral data will be collected on individuals living (1) in different habitats; (2) at different population densities; and, (3) in different-sized social groups. A comparative analysis of the results will be done to test various hypotheses generated from sociobiological theory. One hypothesis, for example, is "Group members share resources with relatives" more than with non-relatives. The research is able to concentrate on individual strategies because most of the total population of 350 howlers are uniquely marked and identifiable. Long-term and multidisciplinary studies of marked animals can provide valuable information on life-history variables and kinship relationships, factors which can change over time. Many species of nonhuman primates are either threatened or highly endangered and attempts are being make to protect the most endangered. One powerful tool in this regard is mathematical modeling, and models must be tested with data from long-term demographic studies such as this one.
