| Outline of Final Research Achievements |
It is one of crucial issues to evaluate the structural and functional response of terrestrial forest ecosystems in changing climate in the future. We examined what factors regulated carbon balance in the representative cool temperate and sub-boreal forest ecosystems to extreme climate events by using Bayesian inversion approach. As examples we use two types of extreme events relevant for cool-temperate regions, i.e. a typhoon in Japan and a heat wave in Germany.
We found that forests with moderate disturbance show substantial functional recovery, productivity, and thus ecosystem carbon exchange, although the effect of extreme climatic events varies depending on the stand successional phase and the type, intensity, and legacy of the disturbance.
