Our ideas have evolved over the years and been shaped by fruitful, and often
spirited, discussions with many colleagues. Among the most memorable of these
were discussions with Don DeAngelis, Jeff Klopatek, John Krummel, and George
Sugihara in the “pre-landscape” years at ORNL that crystallized much of the phi-
losophy and approach adopted in our research. Virginia Dale, Kim With, Scott
Pearson, and Bill Romme have been regular collaborators as well as supportive
friends. Although it is impossible to mention everyone at ORNL that contributed
ideas and assisted us with their expertise, we would be remiss not to acknowledge
the valuable contributions of Steve Bartell, Antoinette Brenkert, Carolyn Hunsaker,
Tony King, and Robin Graham. While at Oak Ridge we hosted a number of visitors
from other institutions, including Bill Romme, Linda Wallace, Bruce Milne, Tim
Kratz, Sandra Lavorel, Tim Allen, Eric Gustafson, and Roy Plotnick. Those col-
leagues made substantial contributions to and lasting impacts on our ideas, and we
thank them all for engaging interactions and fruitful collaborations.
Special thanks are due to Richard Forman, Frank Golley, and John Wiens for
long-standing collegial relationships, the sharing of their ideas (and students!) that
often challenged our thinking, and their invaluable reviews and critiques over the
years. Turner also sincerely thanks Hazel Delcourt (University of Tennessee) and
David Mladenoff (University of Wisconsin), with whom she has jointly taught
landscape ecology courses over the past decade; co-teaching has been inspiring,
fun, and has certainly helped shape her thinking.
This book benefi ted tremendously from valuable critical comments provided by
numerous colleagues. We especially thank David Mladenoff and Sarah Gergel,
who both read nearly the entire manuscript and provided constructive criticism
that has been enormously helpful. David Mladenoff actually read the whole man-
uscript twice, and Turner especially thanks him for being such a good colleague.
In addition, we are grateful to the following friends and colleagues for reviewing
one or more chapters: Jeff Cardille, Steve Carpenter, F. S. (Terry) Chapin, Mark
Dixon, Tony Ives, Dan Kashian, Jim Miller, Bill Romme, Tania Schoennagel, Steve
Seagle, Emily Stanley, Dan Tinker, Phil Townsend, and Kim With. Comments on
draft chapters from the students in “Principles of Landscape Ecology,” taught at
the University of Wisconsin-Madison during the spring 1999 semester, were also
very helpful.
The graphics and illustrations for this book were prepared by Michael Turner,
and we are indebted to him for greatly improving the visual communication of the
concepts and examples in this book. We are delighted with the clarity and consis-
tency of the fi gures throughout the text. We thank Kandis Elliot (University of
Wisconsin) and Michael Mac (Biological Resources Division, U.S. Geological
