Phosphorus control of Bornean tropical rain forests : bottom-up effects on the ecosystem and plant adaptations

据预测，土壤磷的浓度低，由于土壤风化和残留的土壤磷将不会提供给生物区系，由于其与风化土壤矿物的强吸附在婆罗洲的内陆热带雨林生态系统。我们广泛调查了婆罗洲，并选择了低磷可用性的森林生态系统。本文通过对树木磷素利用效率和磷素吸收效率的生理生态学研究，以及土壤微生物群落的作用，阐明了磷素限制雨林长期可持续性的机制。

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.
