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. Key Features: • Presents a forward-looking perspective regarding the response of stream ecosystems to environmental change. • Provides a synthesis of the latest findings on stream ecosystems ecology in one concise volumen. • Includes thought exercises and discussion activities throughout, providing valuable tools for learning. • Offers conceptual models and hypotheses to stimulate conversation and advance research. eng
