| Outline of Final Research Achievements |
We aimed to investigate how the profiles of tree-ring stable isotope ratios reflect the meteorological conditions and physiological response of trees to meteorological fluctuation in a deciduous tropical seasonal forest and a tropical rainforest. We measured the intra- and inter-annual variations in the stable carbon and oxygen isotope compositions of tree-rings and dated the tree-ring formation. The relationships and the time-lag of the profiles of tree-ring stable isotope ratios with rainfall, soil moisture, and index of physiological response of trees estimated from CO2/H2O exchanges data measured above the canopy were examined.
