| Research Abstract |
For the purpose of evaluating coexistence mechanisms of tree species in tropical and subtropical rain forests in South-East Asia, we estimated demographic and allometric parameters in terms of community-wide and species-specific Bayesian probability distributions by employing long-term forest-plot census data. Based on estimated parameters we examined inter-specific trade-offs in demography and allometry. We evaluated contributions of detected trade-offs and disturbance-responses to coexistence by means of the analysis of stratified competition model.
