| Research Abstract |
It was predicted that the concentration of soil phosphorus was low due to soil weathering and the residual soil phosphorus would not be available to biota due to its strong sorption with weathered soil minerals in the inland tropical rain forest ecosystems in Borneo. We widely surveyed Borneo and selected forest ecosystems of low phosphorus availability. We studied the ecophysiology of phosphorus-use efficiency and phosphorus acquisition efficiency of trees as well as the roles of soil microbial communities to elucidate the mechanisms of long sustainability of such phosphorus-limited rain forests.
