"This book emphasizes the idea that much of the progress in ecosystem research has been driven by the emergence of new environmental problems that could not be addressed by existing approaches. By focusing on successes, limitations, and frontiers in ecosystem studies, it will be welcomed by students and scientists throughout the ecological and environmental communities."--Jacket. 1.
