This book addresses a wide array of past, current, and future issues in landscape ecology to provide an overview of the varied viewpoints and perspectives that make landscape ecology a focused as well as a frustratingly diverse discipline. Essays by leading landscape ecologists span multiple spectrums, addressing scientific theory as well as applied practice, conservation as well as utilization, and aquatic as well as terrestrial systems.
