Informationen zum Autor Dr. Schlesinger is one of the nation’s leading ecologists and earth scientists and a passionate advocate for translating science for lay audiences. A member of the National Academy of Sciences, he has served as dean of the Nicholas School of the Environment at Duke and president of the Cary Institute of Ecosystem Studies. He lives in Down East Maine and Durham, N.C. and continues to analyze the impacts of humans on the chemistry of our natural environment. Klappentext For the past 3.8 billion years! the geochemistry of the Earth's surface - its atmosphere! waters and exposed crust - has been determined by the presence of biota. Photosynthetic organisms exposed the Earth's surface to oxygen! denitrifying bacteria have maintained the nitrogen concentration in Earth's atmosphere! and land plants have determined the rate of chemical weathering. Life determines the global biogeochemical cycles of the elements of biochemistry! especially C! N! P and S. Volume 8 traces the origin and impact of life on the geochemistry of the Earth's surface! with special emphasis on the current human impact on global biogeochemical cycles. Reprinted individual volume from the acclaimed Treatise on Geochemistry! (10 Volume Set! ISBN 0-08-043751-6! published in 2003) * Comprehensive and authoritative scope and focus * Reviews from renowned scientists across a range of subjects! providing both overviews and new data! supplemented by extensive bibliographies * Extensive illustrations and examples from the field Zusammenfassung For the past 3.8 billion years! the geochemistry of the Earth's surface - its atmosphere! waters and exposed crust - has been determined by the presence of biota. This book traces the origin and impact of life on the geochemistry of the Earth's surface! with special emphasis on the human impact on global biogeochemical cycles. Inhaltsverzeichnis 1.
