Book excerpt: "Protozoa may not be the first things that come to mind when you think of adaptation, evolution, food webs, succession, physiology, life strategies, and chemical susceptibility. These microorganisms, however, are a great tool to model these and other macro-concepts. Protozoa perform many of the same biological and ecological activities seen in their macroscopic counterparts. And they are much easier to find and cultivate. This book's 28 hands-on activities will help teach organizing principles of biology and ecology, and make links to other disciplines."--Back cover
