| Research Abstract |
There are two major theories on the coexistence of species in tree community : equilibrium and non-equilibrium theories. The former is based on the niche and tradeoffs between traits and athe latter emphasize stochastic process rather than niches. According to the equilibrium theory, the distribution of a species is determined by the ecological traits of the species and its response to the environment. On the other hand, non-equilibrium theory insists stochastic uncertainty that a species can not be at a site because of recruit limitation, and that is why we can not explain the species presence only by ecological traits and environment. In this study, to quantitatively evaluate the contribution of recruit limitation, we tried to answer the questions as bellows. 1)Do the seeds arriving at every place in a community? 2)Do the safe sites of species differ each other? And 3)how we can evaluate the recruit limitation by the comparison between model recruitment by random dispersal with mortality along environmental conditions and actual. We analyzed the seed and seedling data that have been collected in Ogawa and Kanuma-zawa for more than 10 years, together with the environmental factors (light, soil moisture, vegetation, mineral soil exposure, distance from conspecific adults, seed and/or seedling density etc.) at the sites. As the results, the contributions of environmental factors to the survivals of seed and seedlings were low and the importance of biological (distance, density) and physical (light, soil etc.) varied among species. These results were published as several papers and symposium. The model for quantitative evaluation of recruit limitation has been developed and we are preparing for the publication.
