11/5/2007 Physical Anthropology: Lecture 12 (Chapter 6) I. Primate Ecology A. Like all other animals need energy: maintain normal metabolic processes, regulate essential body functions, sustain growth, development and reproduction B. Total amount of energy required depends on: 1. Basal Metabolic Rate: rate of energy expenditure at rest 2. Active Metabolism: energy needs above baseline to perform daily activities 3. Growth rates 4. Reproductive rate C. A primate’s diet must satisfy nutrient needs and minimize exposure to toxins 1. Obtain nutrients from many different sources D.
