| Global Change and the Terrestrial Biosphere : Achievements and Challenges This book provides the depth of the history of global ecology and reviews the breadth of the ideas being studied today. Each chapter starts with a brief narrative about a scientist whose work traces forward into today's issues in global ecosystems. The discussions are framed in a growing realization that we may be altering the way our planet functions almost before we have gained the necessary knowledge of how it works at all. H.H. ("Hank") Shugart is a systems ecologist who has developed and tested models of biogeochemical cycles, energy flow and secondary succession. He uses individual-based computer models to simulate changes in forest structure and composition over time and in response to environmental change. Ian Woodward is a plant ecologist interested in the impacts of climate and changing carbon dioxide concentrations on plants and vegetation. His research on global climate change makes extensive uses of dynamic global vegetation models. |
