Abstract

The maturation of landscape ecology during the 1980s has brought increased interest in the role of interactions among patches in the behavior of functional landscapes (Wiens et al. 1985, Franklin and Forman 1987). Ecotone theory, a topic with a long history in ecology, has recently been revisited within the context of modern landscape theory (Di Castri et al. 1988). This book is among the first works to evaluate the role of ecotones in functional landscapes (see also Naiman and Decamps 1990, and Holland et al. 1991), with particular reference to implications for managing biological diversity and ecological flows. The chapters in this book are diverse, involving widely different scales, ecological systems, geographic locations, and methods. We attempt, in this chapter, to identify and evaluate central themes emerging from the book. We first consider the ecotone concept, then evaluate central hypotheses, and close by considering implications for research and management.
