'This book focuses on current research investigations of the microbiomes found in animals, plants, and soils. The authors propose an emerging theoretical framework for investigating the complex interactions between microbiomes and their habitats. They promote advancements for studying microbiomes and microorganisms in situ, or in the natural environment, rather than focusing on classical methods using in vitro studies as conducted in labs. Each chapter reveals the significant roles that microbiomes play in biogeochemical cycling and in homeostatic mechanisms of host organisms and natural environments. Also discussed are the impacts of anthropogenic changes on microbiome interactions. Topics in the book include background information on microbiomes, analytical methods for studying them, a review of microbiome research investigations, and biotechnology applications of microbiome research. Each chapter provides a wealth of primary references. As an added plus, the readability level is appropriate for those lacking an extensive background in science.' B. R. Shmaefsky, Choice
