The goal of the proposed research is to evaluate and integrate two kinds of explanation of forest community structure and dynamic previously developed at different spatial scales. Gradient models describe species distributions and community composition in term of environmental factors, which can usually be associated with conditions for plant growth. Resource competition models explain community dynamics and resulting composition in terms of acquisition of limiting resources. We propose to compare qualitative predications from both approaches at a set of scales where we have detailed data on forest composition and dynamics. We plan to develop and test regional gradient predictions of local patterns, with a set of intensive study sites representing major forest types on the coastal plain and piedmont of the Southeastern United States. We will also compare the results of empirical models of within- and across-site spatial and temporal distribution, i.e. gradient and stage-projection models, with heuristic results from a proposed resource-competition modeling system. 13 ref., 4 fig.
