Arising from the third Cary Conference held in 1989, Comparative Analyses of Ecosystems investigates the utility and limitations of cross-system comparisons in ecology. The contributors, all well-known in their field, support their conclusions on the use and meaning of such comparisons by presenting novel analyses of data utilizing a variety of cross-system approaches in marine, freshwater, and terrestrial systems.
