River and Stream Ecosystems of the World. Questo articolo non è disponibile.River and Stream Ecosystems of the World

Rivers and streams around the world that once flowed wild and unchecked are rapidly disappearing into dams or being channelized between concrete banks. This valuable sourcebook, now available to a wide audience in a paperback edition, is an important comparative documentation of what is being lost: naturally flowing river and stream ecosystems. No other single volume brings together so much critical information on rivers and streams worldwide. Each chapter is packed with a wealth of raw data on waterways including the prominent rivers of North America, Central and South America, Europe, Africa, Australia, and Oceania. The volume evaluates the usefulness of the River Continuum Concept and ecosystem-level measurements for evaluating the structure and function of rivers and streams. The new introductory chapter examines the relevance of other useful concepts including Nutrient Spiraling, Patch Dynamics, the Flood Pulse Concept, the Network Dynamics Hypothesis, and the Hyporheic Corridor Concept.
