Microbial ecology

"Microbial ecology is the ecology of microorganisms: their relationship 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. Microbial life plays a primary role in regulating biogeochemical systems in virtually all of our planet’s environments, including some of the most extreme, from frozen environments and acidic lakes, to hydrothermal vents at the bottom of deepest oceans, and some of the most familiar, such as the human small intestine. This book details the study of microbes in the environment and their interactions with each other."
