Informationen zum Autor Dan Charman is the author of Peatlands and Environmental Change , published by Wiley. Klappentext Peatlands and Environmental Change provides a comprehensive summary of peatland science. The emphasis is on peatlands as dynamic parts of the landscape that are undergoing constant change as a result of processes of peat accumulation and development, as well as through human activity and climatic variability. The book is divided into four parts that look in turn at the nature of peatland classification and terminology, hydrological and ecological processes and peatland growth, changes in peatlands and their influence on the environment, and resource management issues. Each chapter is supported by examples from all the main peatland regions and site types including New Zealand, Australia and the tropics, as well as Europe and North America. Peatlands and Environmental Change is an ideal introduction to peatlands for those developing an understanding of these ecosystems, and for specialists who wish to broaden their knowledge. Zusammenfassung Considering peatlands as a whole ecosystem! Peatland Systems and Environmental Change provides a unique! timely look at the consequences of the functioning of peatlands to the paleoenvironmental record! carbon cycling! and conservation issues.
