Charles D. Canham and Jonathan J. Cole are scientists with the Institute of Ecosystem Studies, which hosted the Cary Conference. William K. Lauenroth is a Professor in the Department of Forest, Rangeland, and Watershed Stewardship at Colorado State University. Quantitative models are crucial to almost every area of ecosystem science. They provide a logical structure that guides and informs empirical observations of ecosystem processes. They play a particularly crucial role in synthesizing and integrating our understanding of the immense diversity of ecosystem structure and function. Increasingly, models are being called on to predict the effects of human actions on natural ecosystems. Despite the widespread use of models, there exists intense debate within the field over a wide range of practical and philosophical issues pertaining to quantitative modeling. This book--which grew out of a gathering of leading experts at the ninth Cary Conference--explores those issues.
The book opens with an overview of the status and role of modeling in ecosystem science, including perspectives on the long-running debate over the appropriate level of complexity in models. This is followed by eight chapters that address the critical issue of evaluating ecosystem models, including methods of addressing uncertainty. Next come several case studies of the role of models in environmental policy and management. A section on the future of modeling in ecosystem science focuses on increasing the use of modeling in undergraduate education and the modeling skills of professionals within the field. The benefits and limitations of predictive (versus observational) models are also considered in detail. Written by stellar contributors, this book grants access to the state of the art and science of ecosystem modeling. "In the book, a group of excellent ecologists share with you their experience of working with ecological models, their insights into various modeling issues, and their visions of future directions. . . . Experienced modelers or experimentalists with strong interests in modeling can learn a great deal from this book."---Yiqi Luo, Ecology "This book is timely and will be of interest and importance to a broad scientific audience. The field of ecosystem science is at a crossroads, and this book goes a long way to educate modelers, empirical researchers, and policymakers alike."-Jed P. Sparks, Cornell University "This is an impressive collection of work by an impressive group of leaders in the field. The scholarship is excellent, and the concept is novel. I look forward to using the book in my next modeling class, and I predict that students will really like it!"-James Reynolds, Duke University
