| Outline of Final Research Achievements |
I conducted the measurements of leaf-level ecophysiological traits, which influence the carbon and water cycle of the ecosystem, in Indochina Peninsula. Periodical monitoring and inverse modelling of leaf-level traits using the weather and continuously obtained sap flux data suggested the species-specific seasonality in transpiration rates in responses to the flooding and drought. Among the leaf traits, photosynthetic capacity did not show clear seasonality, suggesting that plastic ecophysiological traits, leaf water use efficiency, changed the transpiration rates under environmental changes in this region. Knowledge obtained in this study will be useful for the precise prediction of carbon and water exchange between the atmosphere and the vegetation. Without knowledge obtained in situ, ecophysioloigcal traits obtained in nearby but different environments will provided biased modeled carbon and water exchange.
