| Research Abstract |
To comprehensively analyze the relationship between tree demographic parameters and functional traits those area associated with ecological functions such as photosynthesis or litter decomposition, we built (1) a database of tree demographic parameters, and (2) a database of tree functional traits in several old-growth and surrounding secondary forests in Japan and southeast Asia. Particularly, we focused on the relationship between the functional traits and the characteristics of species resprouting ability, which is scarce in previous studies. In Ogawa forests in Japan, we found that the resprouting ability varied largely among species that coexist in a community, and the ability is closely related to the species' shade tolerance and disturbance regime the species adapt to. These results enable us to incorporate the species resprouting strategy into the forest dynamics and/or the mechanisms for species coexistence.
