Insects and Pollution

Insects and Pollution PDF Author: K. Heliovaara
Publisher: CRC Press
ISBN: 1351090526
Category : Science
Languages : en
Pages : 511

Book Description
Insects and Pollution provides a comprehensive overview of both the direct and indirect effects of pollution on insects and discusses the ecological and economic consequences of these changes. The book reviews studies on pollutant-induced changes in insects classified according to their trophic position, taxonomy, and developmental stage. These changes are considered on different spatial and temporal scales, in different climatic and vegetation zones, and in different habitats (with emphasis on coniferous forests). The book also describes the effects of a variety of pollutants on terrestrial and aquatic ecosystems. Other topics considered include the effects of pollutants on insect physiology, ecology and evolution, and updating and synthesizing data. Insects and Pollution is the first book to combine entomological and ecotoxicological perspectives to address the far-ranging effects of pollution on insects. It is essential reading for entomologists, ecotoxicologists, conservation biologists, and other professionals in the environmental sciences.
