Alaska's great size is mirrored by the large number and diversity of its freshwater ecosystems. This volume reviews and synthesizes research on a variety of Alaskan freshwaters including lakes, rivers and wetlands. The vast range of Alaskan habitats ensures that the chapters in this book will provide valuable information for readers interested in freshwaters, particularly nutrient dynamics, biotic adaptations, recovery mechanisms of aquatic biota, stream succession and the management of human-induced changes in aquatic habitats.
