This much revised and expanded edition provides a valuable and detailed summary of the many uses of diatoms in a wide range of applications in the environmental and earth sciences. Particular emphasis is placed on the use of diatoms in analysing ecological problems related to climate change, acidification, eutrophication, and other pollution issues. The chapters are divided into sections for easy reference, with separate sections covering indicators in different aquatic environments. A final section explores diatom use in other fields of study such as forensics, oil and gas exploration, nanotechnology, and archaeology. Sixteen new chapters have been added since the first edition, including introductory chapters on diatom biology and the numerical approaches used by diatomists. The extensive glossary has also been expanded and now includes over 1,000 detailed entries, which will help non-specialists to use the book effectively.

Timely synopsis of applications in environment and industry using ubiquitous microscopic algae.

This volume presents information and techniques which are at the leading edge of microbial acid rain research and addresses a number of topical and important issues of global concern. Topics discussed include microbial responses to low pH and biogeochemical processes. Cycling of organic matter, microbial interactions with higher forms of biota, and the factors affecting these processes and interactions are described. This book is of special interest to researchers and those involved in management of acid - stressed waters.

various places of the world. Thus, it is hoped that this up-to-date subseries would increase the "awareness" of the world's citizens and encourage governments to devote more attention and resources to address this issue. The series editors thank the international panel of contributors for bringing this timely series into completion. We also wish to acknowledge the very insightful input of the following colleagues: Prof. A. L. Page ofthe University of California, Prof. T. C. Hutchinson of the University of Toronto, and Dr. Steve Lindberg of the Oak Ridge National Laboratory. We also wish to thank the superb effort and cooperation of the volume editors in handling their respective volumes. The constructive criticisms of chapter reviewers also deserve much appreciation. Finally, we wish to convey our appreciation to my secretary, Ms. Brenda Rosier, and my technician, Ms. Claire Carlson, for their very able assistance in various aspects of this series. Aiken, South Carolina Domy C. Adriano Coordinating Editor Preface to Acidic Precipitation, Volume 4 (Advances in Environmental Science) Acidic precipitation and its effects have been the focus ofintense research for over two decades. Initially, research centered on the acidity status and acidification of surface waters and consequent impact on the status of sports fisheries; evidence suggested impacts on fisheries in Sweden and Norway, and in North America, in eastern Ontario, Quebec, and in the Adirondack Mountains of New York.

Selected papers regarding conditions found in Elk Lake, Minnesota being evidence for rapid climate change in the north-central United States. Among the topics: the chronology of Elk Lake sediments, climate and limnological settings, and deposition of calcium carbonate. Annotation copyright Book News

WorldMinds provides broad exposure to a geography that is engaged with discovery, interpretation, and problem solving. Its 100 succinct chapters demonstrate the theories, methods, and data used by geographers, and address the challenges posed by issues such as globalization, regional and ethnic conflict, environmental hazards, terrorism, poverty, and sustainable development. Through its theoretical and practical applications, we are reminded that the study of Geography informs policy making.
