Insects play essential roles in ecosystems and, next to humans, have the greatest capacity to engineer ecosystem structure and function. Insect Ecology: An Ecosystem Approach, 6th Edition provides the most advanced synthesis of insect ecology, including both the traditional foci of insect ecology on adaptations to environmental conditions, population dynamics and community interactions and the roles of insects in regulating ecosystem structure, function and the delivery of ecosystem services. The work integrates two major approaches in insect ecology: the traditional emphasis on insect adaptations, population dynamics and community interactions and a modern emphasis on insect contributions to, and potential regulation of, ecosystem structure and function. This approach emphasizes the ecosystem as the environment that shapes insect adaptations and, in turn, is influenced by insect adaptations. Insect Ecology: An Ecosystem Approach, 6th Edition serves as an invaluable resource graduate students in insect ecology. Professional entomologists and ecologists and practitioners in forestry, agriculture, pest management and conservation ecology will also benefit from the updated information on this dominant group of organisms.
• Emphasizes the importance of landscape variation the role of disturbances in shaping insect populations
• Covers the role of disturbances in shaping insect populations and the ecosystem as a whole
• Describes the importance as insurance for maintenance of ecosystem functions
• Covers the role of disturbances in shaping insect populations and the ecosystem as a whole
• Describes the importance as insurance for maintenance of ecosystem functions

Timothy D. Schowalter
Timothy D. Schowalter received his Ph.D. degree in Entomology from the University of Georgia in 1979. He is currently a Professor of Entomology at Louisiana State University, where he also served as the department head until 2015. Previously, he was a professor of entomology at Oregon State University, Corvallis. Dr. Schowalter served as Program Director for Integrative and Theoretical Ecology at the National Science Foundation, where he was involved in developing global change and terrestrial ecosystem research initiatives at the federal level. He also served as a U.S. delegate to international conventions to develop collaboration between U.S. Long Term Ecological Research (LTER) sites and long-term sites in Hungary and East Asia and the Pacific.
