Front Cover; Stream Ecosystems in a Changing Environment; Copyright; Dedication; Contents; Contributors; Acknowledgments; Chapter 1: Hydrologic Exchange Flows and Their Ecological Consequences in River Corridors; Introduction; Origins of a Hydroecological Perspective in River Corridors; Delineating Hydrologic Exchange Flows (HEFs); Ecological Relevance of HEFs; Fluvial, Geomorphic, and Biological Influences on HEFs; Physical Drivers of HEFs; Hyporheic Exchange Flows; Hydrologic Exchange with Off-Channel Surface Waters; Bioroughness, Burrowing, and Bio-irrigation; Temporally Dynamic HEFs Flood and ET-Driven Vertical Exchange with StreambedBank Storage Exchange Flows; River-Floodplain Exchanges; Watershed Influences; Understanding Controls and Predicting Consequences Across Scales; Overview of Modeling Approaches; Modeling Transport in River Corridors: From Spiraling to Transient Storage; Water Mass Balance; Combined Water and Chemical Mass Balance; Reactive Chemical Transport; The Spiraling Model; Modeling Reactive Chemical Transport in Streams with Storage Zones; Dynamic Reactive Transport Simulated by the Transient Storage Model; Interpretation of HEF Parameters Prediction of HEFs Through Statistical Analysis of Published Data SetsPrediction of HEFs Using Physically Based Scaling Equations; Hydrogeologic Modeling of HEFs; Modeling Dynamic Exchanges with River Banks and Floodplains; Incorporating the Multiple Scales of Exchange Flows in River Network Models; Modeling Cumulative Effects of HEFs in River Networks; Synthesis: From Challenges Emerge Opportunities; Conclusions; Topics to Stimulate Discussion; References; Chapter 2: Shaping the Physical Template: Biological, Hydrological, and Geomorphic Connections in Stream Channels; Introduction Range of Variability in Alluvial ChannelsDisturbance-Recovery Regimes; Water-Sediment-Morphology Interactions; Vegetation Interactions; Bio-Hydro-Geomorphic Templates for Stream Ecosystems; Hydrogeomorphic Template for SW-GW Exchange; Hydrogeomorphic Template for Light Availability; Channel Complexity; Geomorphic Considerations for Environmental Flows; Geomorphically Effective Environmental Flows; Environmental Flow Challenges in Intensively Altered River Systems; Looking Forward and Downstream; Are Rivers Just Large Streams?; What Happens When Flow is No Longer Unidirectional? How Do Response Times in Stream Ecology Compare to Those in Fluvial Geomorphology?Which New Techniques and Technologies Will Allow Us to Answer the Above Questions?; Discussion Questions; Should We Restore Channel Complexity?; How Do We Disentangle the Various Urban Influences on SW-GW Exchanges?; What Would a Fluvial Geomorphic Model for Channel-Riparian Connections Look Like?; References; Chapter 3: Stream Microbial Ecology in a Changing Environment; Introduction; Changing Scientific Capacity; Technological Advances; Changing Template for SME; Conclusions; Future Directions
Stream Ecosystems in a Changing Environment synthesizes the current understanding of stream ecosystem ecology, emphasizing nutrient cycling and carbon dynamics, and providing a forward-looking perspective regarding the response of stream ecosystems to environmental change. Each chapter includes a section focusing on anticipated and ongoing dynamics in stream ecosystems in a changing environment, along with hypotheses regarding controls on stream ecosystem functioning. The book, with its innovative sections, provides a bridge between papers published in peer-reviewed scientific journals and the findings of researchers in new areas of study.
