About this book

Wardle integrates a vast body of literature from numerous fields - including population ecology, ecosystem ecology, ecophysiology, ecological theory, soil science, and global-change biology - to explain the key conceptual issues relating to how aboveground and belowground communities affect one another and the processes that each component carries out. He then applies these concepts to a host of critical questions, including the regulation and function of biodiversity as well as the consequences of human-induced global change in the form of biological invasions, extinctions, atmospheric carbon-dioxide enrichment, nitrogen deposition, land-use change, and global warming.

Highly recommended for all ecologists. Choice I suspect that this book, if for nothing else than for the sheer weight of its intellectual synthesis, will be among [the] classics for many years to come. -- Patrick Bohlen Ecology
