Beschreibung

"Peter Vitousek is tied closely to the 'aina--the land--of Hawaii, both by birth and by the successful scientific career he has nurtured over the past two decades. His personal, and sometimes passionate, presentation sweeps across habitats, across phyla and across disciplines. It is an authoritative account of his research and his vision."--David M. Karl, University of Hawaii

Pressestimmen

Winner of the 2005 Marsh Ecology Book of the Year Award, British Ecological Society "[Vitousek's] work began by understanding the interactive controls over nutrient limitation after forest disturbance. In Nutrient Cycling and Limitation, Vitousek explores this theme on a grand canvas, basing it on his own work and that of a small army of students and collaborators... This book will reward reading and re-reading, and is an excellent introduction to biogeochemical ecology for those coming from other fields of science."--David Schimel, Nature "One of the most impressive aspects of Nutrient Cycling and Limitatio is the scope of the material it covers, and the extent to which the material is integrated to provide a truly ecosystem-level overview, that is itself placed neatly within a global context... [T]he book provides a wide-ranging and authoritative coverage of a crucial topic."--Graeme Hastwell, Austral Ecology "Peter Vitousek's Nutrient Cycling and Limitation makes an important contribution to the field of biogeochemistry... [An] excellent book... Nutrient Cycling and Limitation is essential reading for students and scientists interested in terrestrial biogeochemistry. It is a model of good science writing and a crisp and clear introduction to some of the big ideas that intrigue ecosystem ecologists."--Jerry Melillo, Bioscience
