The Nature of Dietary Differences Between Apes and Monkeys

这项建议的主要目的是研究饮食 一只猿（黑猩猩）和几只 乌干达基巴莱森林中的同类猴子。 体质人类学家多年来一直在争论 猴子相对于猿类的更大成功， 中新世和猿类物种数量的明显减少。 兰厄姆假设猴子的成功 由于它们能够处理植物中的次生化合物 比猿更有效。 这些化合物是各种 限制动物食物选择的毒素无法解毒 消化它们 这一假设的证实将被推进 通过观察这两种灵长类动物在一个 同步研究 在这项研究中，研究人员将观察 研究物种在饲养期间，以量化饮食 摄入 此外，还将收集食品样品， 实验室分析 然后将对数据进行分析， 选择和组成，并用于澄清栖息地 被这类猿和三种猴子利用。

The primary objective of this proposal is to study the dietary choices demonstrated by an ape (the chimpanzee) and several congeneric species of monkeys in the Kibale Forest of Uganda. Physical anthropologists have for many years debated the reasons for the grater success of monkeys relative to apes since the Miocene and the clear diminution in the number of species of ape. Wrangham has hypothesized that the success of the monkeys has been due to their ability to process secondary compounds in vegetation more effectively than apes. These compounds are a variety of toxins which limit the food choices of animals unable to detoxify and digest them. Confirmation of this hypothesis will be advanced by observation of the food choices of the two primates during a synchronous study. In this study the investigators will observe the food choices of the study species during feeding in order to quantify the dietary intake. In addition samples of the foods will be gathered for laboratory analysis. The data will then be analyzed for food choices and composition and the used to clarify the habitat utilization by this ape and the three monkey species.
