Description / Table of Contents:
The arctic region is predicted to experience the earliest and most pronounced global warming response to human-induced climatic change. This book synthesizes information on the physiological ecology of arctic plants, discusses how physiological processes influence ecosystem processes, and explores how climate warming will affect arctic plants, plant communities, and ecosystem processes. Key Features * Reviews the physiological ecology of arctic plants * Explores biotic controls over community and ecosystems processes * Provides physiological bases for predicting how the Arctic will respond to global climate change.
