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.

为了全面分析树木人口统计参数与光合作用或凋落物分解等生态功能相关区域的功能性状之间的关系，我们建立了(1)树木人口统计参数数据库和(2)日本和东南亚几个老树及周边次生林的树木功能性状数据库。特别是，我们重点研究了功能性状与物种再生力特征之间的关系，这在以往的研究中是很少的。在日本小川森林中，我们发现在同一群落中共存的不同物种的再生能力差异很大，而且这种能力与物种适应的遮荫耐受性和干扰机制密切相关。这些结果使我们能够将物种再生战略纳入森林动态和/或物种共存机制。
