| Outline of Final Research Achievements |
General flowering, which is unique phenomenon in tropical rainforests in Southeast Asia, was analyzed by both experimental approach and observation of natural processes. In particular, we tried to make drought experiment using large umbrella around target trees and make sampling analyses by using canopy crane in a forest at Lambir Hills National Park, Sarawak, Malaysia. We tried to elucidate the relationships between flowering and 1) water-use characteristics of trees, 2) nutrient cycling, and 3) interactive features with insects relating to pollination and seed predation. General flowering is clearly induced by short-term drought, and the seed production was related to the nutrient dynamics of the trees. The insect dynamics were closely related to such tree phenology.
