Introduction A variety of types of models currently are being used to evaluate potential effects of elevated CO and climate change on terrestrial ecosystems and the feedbacks to the climate system (see reviews by Ågren et al., 1991; Reynolds et al., 1996; Goudriaan et al., 1999). Such models are employed by scientists as research tools to synthesize scientific understanding, identify important uncertainties, and guide future experiments or field work. In addition, models of ecosystem responses to cli- mate change increasingly will be utilized in comprehensive assessments of climate change designed to help decision-makers in making difficult policy decisions. A widely used class of ecological models is known as gap models (descendants of JABOWA, e.g., Botkin et al., 1972; Shugart, 1984; Bugmann et al., 1996). These models were TI - How Much Physiology Is Needed in Forest Gap Models for Simulating Long-Term Vegetation Response to Global Change?
