New and expanded for its second edition, Environmental Microbiology: From Genomes to Biogeochemistry is a timely update to a classic text filled with ideas, connections, and concepts that advance an in-depth understanding of this growing segment of microbiology. Core principles are highlighted with an emphasis on the logic of the science and new, methods-driven discoveries. Numerous up-to-date examples and applications boxes provide tangible reinforcement of material covered. Study questions at the end of each chapter require students to utilize analytical and quantitative approaches, to define and defend arguments, and to apply microbiological paradigms to their personal interests. Essay assignments and related readings stimulate student inquiry and serve as focal points for teachers to launch classroom discussions. A companion website with downloadable artwork and answers to study questions may also be available.  Environmental Microbiology: From Genomes to Biogeochemistry offers a coherent and comprehensive treatment of this dynamic, emerging field building bridges between basic biology, evolution, genomics, ecology, biotechnology, climate change, and the environmental sciences.
