"Nearly every major river in the world is now regulated by dams or diversions, yet ecological manifestations of river regulation remain undocumented and management alternatives are not available. This book is the first comprehensive review of existing knowledge on the ecology of stream regulation. The text focuses specifically on downstream effects, emphasizing the ecological and biological impact of dams. ...The book begins with a state-of-the-art description of the natural ecosystem by K.W. Cummins. Subsequent articles, written by scientists with outstanding research experience in their subject areas, examine all aspects of the limnology of regulated streams. The modifications of physical, chemical, and hydrological gradients in streams below impoundments are examined as causative agents for profound changes in indigenous biotic components, including phytobenthos, zoobenthos, and fishes. ...The editors conclude that regulated streams are now the most prevalent lotic environments on earth. The Ecology of Regulated Streams provides a foundation for pure and applied study of these altered ecosystems".
