Abstract

Masting-dependent changes in canopy structure, light interception, and photosynthesis in natural Fagus crenata forests were examined with field-research and light transfer model. Masting significantly decreased canopy leaf area, especially in the upper layer, but increased whole canopy photosynthesis because of increased light interception in the lower layer. These masting-dependent changes are important for precise carbon budget estimation in forest ecosystems.
