J. David Allan – författare

Streams is a handbook that combines a discussion of the ecology of streams and rivers, in layperson language, with an illustrated field guide of the plants and animals found in running waters of North America. Various illustrations and maps accompany the text. The authors are extremely well known--Cushing is the lead content provider for an America On-Line service provided through Trout Unlimited entitled "Ask Dr. Cushing." He is frequently asked the sorts of questions that are answered in this field guide. J. David Allan is the author of a well known textbook in Aquatic Ecology.

This text emphasizes the ecological processes that influence community organization and ecosystem function in running waters. After providing an introduction to the physical and chemical circumstances of running water, there is an analysis of the biology and ecology of these systems, covering the following topics: the ecological role of autotrophic and heterotrophic energy producers; the trophic ecology of consumer organisms in lotic food webs; the community ecology of flowing waters, including herbivory, predation and competition, and their integration with abiotic factors in determining community organization; downstream drift; the dynamics of organic matter and of elements, including the concepts of mass balance and spiralling; the effects of humans on river systems; management and conservation of rivers and their biota. This book is intended to be of use to undergraduates, researchers and specialists in stream ecology and related fields.

Stream Ecology: Structure and Function of Running Waters is designed to serve as a textbook for advanced undergraduate and graduate students, and as a reference source for specialists in stream ecology and related fields. The Second Edition is thoroughly updated and expanded to incorporate significant advances in our understanding of environmental factors, biological interactions, and ecosystem processes, and how these vary with hydrological, geomorphological, and landscape setting. The broad diversity of running waters – from torrential mountain brooks, to large, lowland rivers, to great river systems whose basins occupy sub-continents – makes river ecosystems appear overwhelming complex. A central theme of this book is that although the settings are often unique, the processes at work in running waters are general and increasingly well understood. Even as our scientific understanding of stream ecosystems rapidly advances, the pressures arising from diverse human activities continue to threaten the health of rivers worldwide. This book presents vital new findings concerning human impacts, and the advances in pollution control, flow management, restoration, and conservation planning that point to practical solutions. Reviews of the first edition: ".. an unusually lucid and judicious reassessment of the state of stream ecology" Science Magazine "..provides an excellent introduction to the area for advanced undergraduates and graduate students…" Limnology & Oceanography "… a valuable reference for all those interested in the ecology of running waters." Transactions of the American Fisheries Society
