Microbial Ecology of Tropical Soils [PDF ebook] 

Microbial ecology is the interrelationship between microorganisms and their environment. Due to the high level of horizontal gene transfer among microbial communities, microbial ecology is also of importance to studies of evolution. The microorganisms, by their omnipresence, impact the entire biosphere. They present important functions in the soil, as nutrient cycling and the degradation of pollutant. Additionally, soil microorganisms promote other important functions for environmental sustainability. This new book identifies the theory and applications of an integrated approach to microbial ecology of tropical soil.
