This seminal work is designed to serve as a textbook for advanced undergraduate and graduate students, as well as a working reference for specialists in stream ecology and related fields. This new edition is extensively rewritten, with hydrology and geomorphology now accorded chapter-length discussion. Coverage includes a considerably improved and updated treatment of abiotic factors, organized around the habitat template concept. Additional new material outlines important advances in microbial ecology. The book presents vital new findings on human impacts, and new work in pollution control, flow management, restoration and conservation planning that point to practical solutions. All told, the book is expanded in length by some twenty-five percent, and includes hundreds of figures, most of them new. Thoroughly updated and expanded, this edition reflects the enormous growth in our understanding of stream metabolism and nutrient processes, which are the core of ecosystem functioning.

The only text in this field that provides a comprehensive treatment of all relevant topics Written with the express goal of being accessible to students with only modest backgrounds in ecology and aquatic sciences. The First Edition was widely praised for its readability students liked the writing because they could easily follow it and that emphasis is retained Thoroughly updated to include the major advances in stream ecology developed in the last 10 years States principles clearly and succinctly, but includes well-chosen examples that enrich the concepts and provide insights into how studies are conducted in the lab or the field, and where there is controversy or uncertainty Will appeal to those interested in fundamental principles and to those looking for applications to real-world problems Every chapter received thorough reviews from at least two specialists to ensure accuracy as well as inclusion of the most important examples
