II. Introduction

Atmospheric C[O.sub.2] levels have exhibited a steady and substantial rise since preindustrial times, and predictive models indicate that the increase will continue (Raynaud & Barnola, 1985). The global atmospheric C[O.sub.2] concentration is currently at about 280-350 [micro]L/L, but it could double within the next century due to continued increases in fossil fuel use (Bazzaz & Fajer, 1992). The rising atmospheric C[O.sub.2] concentration can influence ecosystems by direct effects on plant growth and ...
