植物生态学的重要目标之一是在驱动群落动态和结构的基本过程与观察到的人口统计学（即，生长、存活和募集）和组装（即，物种的分布）通过性状在群落中。虽然性状对表现的重要性是显而易见的，但它们与人口统计学的直接联系以及由此产生的树木群落中的组装往往被发现是相当弱的，这可能是因为一个物种的单一“平均”性状值不足以捕捉复杂的生活史。在本文中，我们回顾了器官水平和整个植物水平的性状，人口统计学和组装在不同的热带森林中随大小的变化，并总结了我们迄今所知道的。我们认为，基于特征的生活史策略的重要性，揭示了个体发育阶段的特征-环境-人口学联系，以实现形成驱动社区动态和结构的基本过程与观察到的人口统计学和组装之间的机械联系的最终目标。
One of the important goals in plant ecology is to form a mechanistic link between the underlying processes driving the dynamics and structure of communities and the observed demography (i.e., growth, survival, and recruitment) and assembly (i.e., distribution of species) in a community via traits. Although the importance of traits to performance is evident, their direct links to demography and the resulting assembly in tree communities are often found to be fairly weak probably because a single “ mean ” trait value for a species is not enough to capture complex life histories. In this paper, we review how traits at the organ-level and at the whole plant level, demography, and assembly change with size in diverse tropical forests and summarize what we know so far. We argue the importance of trait-based life-history strategies revealing trait-environment-demography linkages across ontogenetic stages to achieve the ultimate goal of forming a mechanistic link between the underlying processes driving the dynamics and structure of communities and the observed demography and assembly.
