Résumé :
|
This book provides an up-to-date overview of the application of ecologically sound approaches, methods and tools using experience gained around the world for an understanding of rivers and their management. In two volumes the Handbook will form a unique and invaluable reference for all those working in the fields of river ecology and management. Volume one treats general scientific and ecological principles that are relevant for developing a rational integrated approach to management. Part one of volume one contains a detailed discussion of the physical and chemical properties of rivers and their immediate surroundings, not only describing their features, but also explaining how they can be measured and how models can be developed around them. Part two considers the river biota, from microbes and primary producers to invertebrate and vertebrate consumers, whilst part three concerns the functioning af river ecosystems : food webs, energy sources and energy flow through communities. Finally the principles considered in earlier sections are addressed as case studies of several rivers covering all major geographical regions - subractic to tropical - and examples from both mountain and lowland regions are discussed.
