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.

热带山脉为植物提供了理想的环境，没有热胁迫和干燥胁迫，在这里我们观察到植物生命形式多样性的广泛变化。本研究旨在研究叶和芽功能的生态生理分化，基于这样的模块级权衡加速这种环境中的分化的假设。主地点设在西爪哇的哈利蒙山国家公园，比较地点设在日本南部屋久岛的暖温带雨林。在哈利蒙山，对110个物种进行了为期三年的树叶种群统计普查。将叶子样品分为细胞壁和原生质成分，以检验细胞壁蛋白随着叶子寿命增加而增加的假设，这违反了叶子寿命与氮含量负相关的简单解释。详细分析了几种独特的生命形式，例如大型附生蕨类植物和攀缘棕榈植物的生长和异速生长。进行了新叶冲刷过程中的水势变化、植物冠内芽间分配模式的塑性控制以及径向茎生长和芽生长之间的分配调节。
