Acknowledgments This special issue was inspired by a half-day symposium held at the 2007 World Congress of Landscape Ecology in Wageningen, the Netherlands, and Jianguo Wu and I appreciate the organizers who helped to make it possible. I want to thank all of the landscape researchers who participated in the symposium and this special issue as well as the reviewers who provided help during the publication process. I am indebted to their efforts to make this special issue possible and especially to Jianguo Wu. In addition, this effort was made possible by my Dayton Hudson Fellowship and an international travel grant from the University of Minnesota.
