For more than fifty years, small numbers of scientists have been concerned with the interrelationships of Earth and life. Over the past decade, however, geobiology has emerged as an exciting and rapidly expanding field. This book sets out a coherent set of principles that underpin geobiology, and will act as a foundational text that will speed the intellectual dissemination of those principles. The book is of interest to advanced undergraduates and graduates in the earth and biological sciences, and to the growing number of scientists worldwide who have an interest in the burgeoning discipline of Geobiology.
Andrew H. Knoll is the Fisher Professor of Natural History at Harvard University. A paleontologist by training, he has worked for three decades to understand the environmental history of Earth and, more recently, Mars. Knoll is a member of the U.S. National Academy of Sciences.
Donald E. Canfield is Professor of Ecology at the University of Southern Denmark and Director of the Nordic Center for Earth Evolution (NordCEE). Canfield uses the study of modern microbes and microbial ecosystems to understand the evolution of Earth surface chemistry and biology through time. Canfield is a member of the U.S. National Academy of Sciences.
Kurt O. Konhauser is a Professor of Geomicrobiology at the University of Alberta. He is Editor-in-Chief for the journal, Geobiology, and author of the textbook, Introduction to Geomicrobiology. His research focuses on metal-mineral-microbe interactions in both modern and ancient environments.
