Beskrivning

This book covers the ecological activities of microbes in the biosphere with an emphasis on microbial interactions within their environments and communities In thirteen concise and timely chapters, Microbial Ecology presents a broad overview of this rapidly growing field, explaining the basic principles in an easy-to-follow manner. Using an integrative approach, it comprehensively covers traditional issues in ecology as well as cutting-edge content at the intersection of ecology, microbiology, environmental science and engineering, and molecular biology.Examining the microbial characteristics that enable microbes to grow in different environments, the book provides insights into relevant methodologies for characterization of microorganisms in the environment. The authors draw upon their extensive experience in teaching microbiology to address the latest hot-button topics in the field, such as: Ecology of microorganisms in natural and engineered environmentsAdvances in molecular-based understanding of microbial phylogeny and interactionsMicrobially driven biogeochemical processes and interactions among microbial populations and communitiesMicrobial activities in extreme or unusual environmentsEcological studies pertaining to animal, plant, and insect microbiologyMicrobial processes and interactions associated with environmental pollutionDesigned for use in teaching, Microbial Ecology offers numerous special features to aid both students and instructors, including: Information boxes that highlight key microbial ecology issues"Microbial Spotlights" that focus on how prominent microbial ecologists became interested in microbial ecologyExamples that illustrate the role of bacterial interaction with humansExercises to promote critical thinkingSelected reading listsChapter summaries and review questions for class discussionVarious microbial interactions and community structures are presented through examples and illustrations. Also included are mini case studies that address activities of microorganisms in specific environments, as well as a glossary and key words. All these features make this an ideal textbook for graduate or upper-level undergraduate students in biology, microbiology, ecology, or environmental science. It also serves as a highly useful reference for scientists and environmental professionals.

Mer om författaren

Larry L. Barton studies the physiological activities of environmentally important microorganisms, focusing on energetics of bacterial inorganic metabolism and bacterial bioremediation. Larry has been the instructor of the course in General Microbiology for over 30 years. The author of five previous books, he was the founding editor and the initial editor-in chief of the international journal Anerobe, begun in 1995 and now published by Academic Press. Most recently, he published a college textbook on bacterial physiology. Diana E. Northup investigates the microorganisms that inhabit caves throughout the world. Her research was featured on the Nova episode, "Mysterious Life of Caves." Within the Department of Biology at UNM, she gives lectures, directs undergraduate students in research, supervises a postdoctoral fellow, and, currently, she is mentoring a doctoral student in microbial ecology of a cave in southern New Mexico.
