Tropical mountains provide ideal environments for plants without thermal and desiccation stresses, and where we observe a wide variation of within-and across-life form diversity of plants. This study aimed to examine ecophysiological differentiation of leaf and shoot function, based on the hypothesis that such module-level tradeoffs accelerate the differentiation in such environment. Main site was set at Mount Halimun National Park in West Java, and a comparative site at warm-temperate rain forests in Yakushima Island, southern Japan.In Mount Halimun, three-year census of leaf demography for 110 species was carried out. Leaf samples were divided into cell-wall and protoplasm components, to test the hypothesis that cell-wall protein increases with leaf longevity, which violates simple explanation of leaf-longevity vs. nitrogen content negative correlation. Several unique life forms such as large epiphytic fern and palm climbers were analyzed their growth and allometry in detail. Water potential change during new leaf flushing, plastic control of among-shoot allocation pattern within a plant crown, and allocation regulation between radial stem growth and shoot growth, were carried out.

热带山脉为没有热应力和干燥应力的植物提供了理想的环境，并且我们观察到内部和跨植物多样性的广泛变化。这项研究旨在基于这样的假设，即这种模块级的权衡加速了这种环境中的分化，旨在检查叶子和芽功能的生态生理分化。主要地点设在西爪哇山的哈利蒙国家公园，在日本南部南部Yakushima岛的温暖雨林中进行了比较地点。将叶片样品分为细胞壁和原生质成分，以检验以下假设：细胞壁蛋白随叶的寿命增加而增加，这违反了对叶子朗格的简单解释与氮含量负相关。详细分析了几种独特的生命形式，例如大型的附生蕨和棕榈登山者。新叶冲洗期间的水潜力变化，植物冠中射击分配模式中的塑料控制以及径向茎生长和芽生长之间的分配调节。
