Microbial ecology is the relationship of microorganisms with one another and with their environment. It concerns the three major domains of life -- Eukaryota, Archaea, and Bacteria -- as well as viruses. Microorganisms, by their omnipresence, impact the entire biosphere. They are present in virtually all of our planet's environments, including some of the most extreme, from acidic lakes to the deepest ocean, and from frozen environments to hydrothermal vents. Microbes, especially bacteria, often engage in symbiotic relationships (either positive or negative) with other organisms, and these relationships affect the ecosystem. One example of these fundamental symbioses are chloroplasts, which allow eukaryotes to conduct photosynthesis. Chloroplasts are considered to be endosymbiotic cyanobacteria, a group of bacteria that are thought to be the origins of aerobic photosynthesis. Some theories state that this invention coincides with a major shift in the early earth's atmosphere, from a reducing atmosphere to an oxygen-rich atmosphere. This book presents new and important research in the field.

This new book presents the latest research in environmental microbiology which is area of interaction that studies the interaction of microorganisms with the environment. It includes the structure, activities and communal behaviour of microbial communities, microbial interactions and interactions with plants, animals and non-living environmental factors, population biology and clonal structure microbes and surfaces, adhesion and biofouling responses to environmental signals and stress factors growth and survival, modelling and theory development, microbial community genetics and evolutionary processes, microbial physiological, metabolic and structural diversity, pollution microbiology, extremophiles and life in extreme and unusual little-explored habitats, primary and secondary production, element cycles and biogeochemical processes and microbially-influenced global changes.

The distribution and function of microorganisms are of crucial importance for the flow of matter in the Earth's biogeochemical cycles. Effects of microbial communities on the carbon and nitrogen cycles are particularly important for producing climate gases such as CO2, CH4, or N2O. However, the biogeochemical cycles are reversely impacted by global climate change, for example by increasing temperature, increasing CO2 concentration, or changing soil humidity. However microbes may respond differently, by accelerating or by alleviating, human-caused climate change. Understanding of microbial ecology in the different ecosystems on Earth, such as soil, oceans, or inland waters, is essential for our ability to assess the importance of biogeochemical cycles-climate feedbacks. Unfortunately, microbial communities are extremely complex in structure and function and can be affected by climate and other global changes in many ways, which impedes our ability to draw reliable conclusions. In this book, a broad range of renowned scientists reviews the most important hot-topics in the area of climate change and microbial ecology, thus providing a timely and authoritative overview of this increasingly important area. Individual chapters cover the various ecosystems on Earth as well as the different groups of microorganisms with respect to different cycles of matter. In addition, special chapters cover applied aspects, such as land-use and geoengineering. This is an essential book for every microbial ecologist from the PhD student to the experienced scientist and is also recommended for everyone interested in the field of global climate change.

Microbes are key drivers of the world's ecosystems. The vast majority of the world's diversity and metabolic potential lies within micro-organisms, yet we are just beginning to understand and utilize this ultimate resource of biological diversity. Critical to our exploration of the microbial world are methods that allow for the analysis of organisms that are invisible to our eyes, difficult to distinguish from each other, and often impossible to grow using available culture methods. The field of microbial ecology has been revolutionized in the past two decades by the introduction of molecular methods into the toolbox of the microbial ecologist. This molecular arsenal has helped to unveil the enormity of microbial diversity across the breadth of the earth's ecosystems, and has revealed that we are only familiar with a very small minority of the organisms that carry out key microbial functions in diverse habitats. The Molecular Microbial Ecology Manual, Second Edition (MMEM-II) provides a detailed and user-friendly description of the methods that have made this revolution in microbial ecology possible. However, what is perhaps most exciting about MMEM-II is that it contains a large number of new chapters, highlighting the newest trends in microbial ecology research, which seek to provide more quantitative and statistically robust data, and means of coupling microbial identity and function. In addition, the majority of the proven methods described in MMEM's first version have undergone significant revisions to provide the most up-to-date applications available. The state-of-the-art methods described in MMEM-II have not only been provided by experts in the field, but in most cases by the laboratories that actually first developed and applied the methods, thus providing the MMEM-II user with unique first-hand tips and insight. The new on-line format available forMMEM-II should also add to the utility of MMEM-II by allowing users to search for key topics throughout the manual, skip between interrelated chapters at the push of a button, and by providing immediate availability to protocol updates and new chapters dedicated to future technical developments.

An authoritative overview of the ecological activities of microbes in the biosphere Environmental Microbiology and Microbial Ecology presents a broad overview of microbial activity and microbes' interactions with their environments and communities. Adopting an integrative approach, this text covers both conventional ecological issues as well as cross-disciplinary investigations that combine facets of microbiology, ecology, environmental science and engineering, molecular biology, and biochemistry. Focusing primarily on single-cell forms of prokaryotes — and cellular forms of algae, fungi, and protozoans — this book enables readers to gain insight into the fundamental methodologies for the characterization of microorganisms in the biosphere. The authors draw from decades of experience to examine the environmental processes mediated by microorganisms and explore the interactions between microorganisms and higher life forms. Highly relevant to modern readers, this book examines topics including the ecology of microorganisms in engineered environments, microbial phylogeny and interactions, microbial processes in relation to environmental pollution, and many more. Now in its second edition, this book features updated references and major revisions to chapters on assessing microbial communities, community relationships, and their global impact. New content such as effective public communication of research findings and advice on scientific article review equips readers with practical real-world skills. Explores the activities of microorganisms in specific environments with case studies and actual research data Highlights how prominent microbial biologists address significant microbial ecology issues Offers guidance on scientific communication, including scientific presentations and grant preparation Includes plentiful illustrations and examples of microbial interactions, community structures, and human-bacterial connections Provides chapter summaries, review questions, selected reading lists, a complete glossary, and critical thinking exercises Environmental Microbiology and Microbial Ecology is an ideal textbook for graduate and advanced undergraduate courses in biology, microbiology, ecology, and environmental science, while also serving as a current and informative reference for microbiologists, cell and molecular biologists, ecologists, and environmental professionals.

This book provides an overview of ecological aspects of the metabolism and behavior of microbes, microbial habitats, biogeochemical cycles, and biotechnology. It was designed by selecting relevant chapters from the comprehensive Encyclopedia of Microbiology, 3rd edn., and inviting the original authors to update their material to include key developments and advances in the field.
