In recognition of the role of plants in the bio-geosphere carbon cycle, the Department of Energy (OHER) initiated a research program: The Direct Effects of Increasing Carbon Dioxide on Vegetation. This report describes the continuing research that we are conducting as part of this program. The ultimate goal of our research is to develop computer models capable of predicting responses of plants and ecosystems to the direct and indirect effects of atmospheric levels of carbon dioxide that are approximately twice those of the preindustrial period. The understanding of ecosystem responses to elevated CO{sub 2} necessarily depends on knowledge of responses of individual plants and their interactions with one another and their environment Our research approach incorporates the study and modeling of response to CO{sub 2} at all levels of the plant-community-ecosystem hierarchy, in an effort to understand the linkages and translation of effects of CO{sub 2} from one level to another. The research results reported here focus at several different levels of this hierarchy, and are highlights of accomplishments for the period September 1992 to June 1993.
