These Living Graph interactive tutorials will help you master important mathematical relationships used in ecology, such as exponential and geometric growth, the logistic equation, and the Lotka-Volterra predator-prey model. Each tutorial walks you through the equations and its variables, and includes a Living Graph that you can manipulate and experiment with. At the end, questions that use the Living Graph test your understanding. Answers to the questions at the end of each tutorial can be sent directly to your instructor. The Help on the Web icons in the textbook tell you when to go to the E-Study Center to find these useful tutorials.
