Use the outline below to guide your study of the material in this lesson. The outline follows the book, but indicates those topics the instructor feels are most important for you to learn in the course. You should read all the pages that are assigned, but the outline will help you focus your study.

I. Introduction

  1. Questions

  2. Distinctions among consumers

II. Limitation of resource populations

  1. Cyclamen mite pest of California strawberries preyed on by Typhlodromus mite

  2. Opuntia in Australia: introduced pest

  3. Sea urchin predators

  4. Parasite-host systems

  5. Herbivore and plant populations

III. Predator-prey cycles

  1. Animals of the Canadian boreal forests and tundra

  2. Laboratory experiments

  3. Huffaker's mites

  4. Three-level consumer system

IV. Models of predator-prey interactions

  1. Lotka-Volterra predator-prey model

  2. Functional response

  3. Numerical response

V. Stability in predator-prey systems

  1. Conclusions from models: long-term persistence of predator-prey interactions are promoted by:

  2. Multiple stable states

  3. Maximum sustainable yield
