Insect Ecology

An Ecosystem Approach

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 covers a range of topics- from individual insects that respond to local changes in the environment and affect resource distribution, to entire insect communities that have the capacity to modify ecosystem conditions.Insect Ecology, Second Edition, synthesizes the latest research in the field and has been produced in full color throughout. It is ideal for students in both entomology and ecology-focused programs.

Audience
Natural resource managers and environmental policy-makers, as well as students and instructors of insect ecology.

Reviews

  • "Schowalter's 2nd edition of Insect Ecology: An Ecosystem Approach is a gem - a complete course in modern ecology from the vantage point of insects in ecological systems. Accessible and engaging, yet it treats the most complex ecological phenomena from individual behavior and population processes through landscape and regional-scale issues." - Dan Simberloff, University of Tennessee "Schowalter provides a well-illustrated, comprehensive integration of population, community, and ecosystem ecology that demonstrates the global importance of insects in terrestrial and aquatic domains. Examples from temperate and tropical studies are related to a wide range of fundamental ecological concepts. The synthesis of current literature is thoroughly developed and will be widely appreciated by beginning students and established professionals." - Alan Covich, Institute of Ecology, University of Georgia "This very stimulating book will interest entomologists and ecologists alike. Schowalter broadens the traditional scope of insect ecology to communities and ecosystems. He gives an excellent overview how insects shape ecosystem functioning, including their critical role in major trophic interactions such as decomposition, pollination, herbivory and biological control." - Teja Tscharntke, University of Göttingen, Germany
