It also serves as a highly useful reference for scientists and environmental professionals.

Microbial ecology is the study of interactions among microbes in natural environments and their roles in biogeochemical cycles, food web dynamics, and the evolution of life. Microbes are the most numerous organisms in the biosphere and mediate many critical reactions in elemental cycles and biogeochemical reactions. Because microbes are essential players in the carbon cycle and related processes, microbial ecology is a vital science for understanding the role of the biosphere in global warming and the response of natural ecosystems to climate change. This novel textbook discusses the major processes carried out by viruses, bacteria, fungi, protozoa and other protists - the microbes - in freshwater, marine, and terrestrial ecosystems. It focuses on biogeochemical processes, starting with primary production and the initial fixation of carbon into cellular biomass, before exploring how that carbon is degraded in both oxygen-rich (oxic) and oxygen-deficient (anoxic) environments. These biogeochemical processes are affected by ecological interactions, including competition for limiting nutrients, viral lysis, and predation by various protists in soils and aquatic habitats. The book neatly connects processes occurring at the micron scale to events happening at the global scale, including the carbon cycle and its connection to climate change issues. A final chapter is devoted to symbiosis and other relationships between microbes and larger organisms. Microbes have huge impacts not only on biogeochemical cycles, but also on the ecology and evolution of more complex forms of life, including Homo sapiens..

This book highlights perspectives, insights, and data in the coupled fields of aquatic microbial ecology and biogeochemistry when viewed through the lens of collaborative duos – dual career couples. Their synergy and collaborative interactions have contributed substantially to our contemporary understanding of pattern, process and dynamics. This is thus a book by dual career couples about dual scientific processes. The papers herein represent wide-ranging topics, from the processes that structure microbial diversity to nitrogen and photosynthesis metabolism, to dynamics of changing ecosystems and processes and dynamics in individual ecosystems. In all, these papers take us from the Arctic to Africa, from the Arabian Sea to Australia, from small lakes in Maine and Yellowstone hot vents to the Sargasso Sea, and in the process provide analyses that make us think about the structure and function of all of these systems in the aquatic realm. This book is useful not only for the depth and breadth of knowledge conveyed in its chapters, but serves to guide dual career couples faced with the great challenges only they face. Great teams do make great science.

From the deep sea, through polar deserts, up to the clouds in the air - the diversity of microbial life in all habitats is described, explored, and comprehensively reviewed. Possible biotechnical applications are discussed. This book aims to provide a useful reference for those who want to start a research program in extreme microbiology and, hopefully, inspire new research directions.

Dr. Joshua Lederberg - scientist, Nobel laureate, visionary thinker, and friend of the Forum on Microbial Threats - died on February 2, 2008. It was in his honor that the Institute of Medicine's Forum on Microbial Threats convened a public workshop on May 20-21, 2008, to examine Dr. Lederberg's scientific and policy contributions to the marketplace of ideas in the life sciences, medicine, and public policy. The resulting workshop summary, Microbial Evolution and Co-Adaptation, demonstrates the extent to which conceptual and technological developments have, within a few short years, advanced our collective understanding of the microbiome, microbial genetics, microbial communities, and microbe-host-environment interactions.

The aim of this comprehensively written volume is to provide a baseline of information on the normal microflora at various sites in the body. It focuses on the mouth, upper digestive tract, large intestine, skin, and urinogenital tract. Written in an easy-to-read format, this book highlights the level of detail available. For example, it explains that in the mouth and colon the data are extremely detailed and good quantitative information is available on large numbers of bacterial species. This work analyzes the similarities and differences between the microfloras of the various "internal" surfaces, and discusses the clear value of good taxonomy. It focuses on problems and extended research in the progress at other sites. Because this work researches the advances and discoveries made in specific areas of human microbial ecology, it is an ideal source for all who are involved in microbiology, bacteriology, and infectious diseases.
