Informationen zum Autor Robert Michener is the Laboratory Manager of the Boston University Stable Isotope Laboratory and has been running the internationally recognized facility for 18 years. His research interests include aquatic ecology, food web systems, and how stable isotopes can be applied to tracing pollutants, comparing pristine and impacted systems. Kate Lajtha is a Professor in the Department of Botany and Plant Pathology at Oregon State University and the Editor-in-Chief of Biogeochemistry . She is a terrestrial biogeochemist who studies soil organic matter stabilization and soil solution chemistry. Klappentext This book highlights new and emerging uses of stable isotope analysis in a variety of ecological disciplines. While the use of natural abundance isotopes in ecological research is now relatively standard, new techniques and ways of interpreting patterns are developing rapidly. The second edition of this book provides a thorough, up-to-date examination of these methods of research.
