For students and practitioners, a comprehensive primer on the key literature in stream and river ecology. The study of streams and rivers combines ecology, chemistry, hydrology, and geology to reveal the factors that control the biological diversity and functioning of these unique ecosystems. Although stream ecology is a relatively young discipline, foundational papers published over the past half century have shaped our current understanding of these ecosystems and have informed our efforts to manage and protect them. Organized by topics such as the physical template, community structure, food webs, ecosystem energetics, and nutrient dynamics, the chapters of this book offer summaries of the key literature, historical and contextual information, and insightful discussions of how past research has influenced present studies and may shape future work.

A sweeping new account of the role of power in the evolution of all life on EarthPower has many dimensions from individual attributes such as strength and speed to the collective advantages of groups The Evolution of Power takes readers on a breathtaking journey across history and the natural world revealing how the concept of power unifies a vast range of phenomena in the evolution of life and how natural selection has placed humanity and the planet itself on a trajectory of ever increasing power Drawing on evidence from fossils living organisms and contemporary society Geerat Vermeij documents increases in power at all scales from body size locomotor performance and the use of force in competition to efficiency in production and consumption within ecosystems He shows how power which he defines as the rate at which organisms acquire and apply energy is tied to the emergence of cooperation and how the modern economy which for the first time has established a monopoly over the biosphere by a single species is a continuation of evolutionary trends stretching back to the dawn of life Vermeij persuasively argues that we can find solutions to the many problems arising from this extreme concentration of power by broadening our exclusively human centered perspe
