Outline of Final Research Achievements

We discussed the significance of "phylogenetic diversity (diversity of evolutionary history)" as an index for biodiversity conservation of tropical rain forest. Using a detailed molecular phylogeny estimated for 699 tree species in a Bornean rain forest, we found that maximum size and demographic traits, such as mortality and growth rates, were more similar among phylogenetically more closely related species, while habitat niche was various even among them. This suggests that niche habitat is an evolutionary labile trait and that divergence in habitat niche may enhance coexistence of closely related species, which have similar adult size and demographic traits. We also found that the relationship between species and phylogenetic diversity was not straightforward but rather complicated, which suggested that we need to consider both species and phylogenetic diversity simultaneously in biodiversity conservation of tropical rain forest.
