Research Abstract

We assessed the environmental sensitivities of forest ecosystem functions in mountainous forest ecosystems in climate change by using field measurement data and ecosystem modeling simulations. We clarified that ecosystem functions were strongly influenced by changing canopy phenology and snow-cover period under global warming. Our analysis indicates the importance of understanding space-time distributions of canopy phenology dynamics and snow-cover and of their consideration into the mechanistic evaluation of ecosystem functions in the climate studies.
