Stream Ecosystems in a Changing Environment synthesizes current understanding in stream ecosystem ecology, emphasizing nutrient cycling and carbon dynamics, and provides a forward-looking perspective regarding the response of stream ecosystems to environmental change. Stream ecosystem ecology has undergone major advances in the past decade following a series of high-profile and innovative research initiatives focusing on nutrient cycling and metabolism. Each chapter includes a section focusing on anticipated and ongoing dynamics in stream ecosystems in a changing environment, and hypotheses regarding controls on stream ecosystem functioning. These innovative sections provide a bridge between papers published in peer-reviewed scientific journals, and researchers' development of new ideas areas of study. * Provides a synthesis of the latest findings on stream ecosystems ecology in one volume* Includes thought exercises and discussion activities throughout, providing valuable tools for learning* Offers conceptual models and hypotheses to stimulate conversation and serve to advance research
