Book excerpt: FROM THE PREFACE: The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion....The goal of this book is to update and advance current thinking on the phenomenon of insect outbreaks. The contributors have reviewed relevant literature in order to generate a synthesis providing new concepts and important alternatives for future research. More importantly, they have presented new ideas or syntheses that will stimulate advances in thinking and experimentation.

Book excerpt: Dr. Timothy Schowalter has succeeded in creating a unique, updated treatment of insect ecology. This revised and expanded text looks at how insects adapt to environmental conditions while maintaining the ability to substantially alter their environment.

It is ideal for students in both entomology and ecology-focused programs.NEW TO THIS EDITION:* New topics such as elemental defense by plants, chaotic models, molecular methods to measure disperson, food web relationships, and more* Expanded sections on plant defenses, insect learning, evolutionary tradeoffs, conservation biology and more* Includes more than 350 new references* More than 40 new full-color figures
