The mechanisms behind the structure and dynamics of plant communities are hotly debated. Two opposing concepts emphasize either niche explanations or, alternatively, dispersal (=neutral) processes. The proposed project takes advantage of the unique opportunity of a complete census of some 13,000 vascular epiphytes in a pristine Panamanian lowland forest that was finished in 2002. Gaining access by use of a tower crane to all strata of the forest, this project will directly document the dynamics of this community in time and space (“pattern”) and use experimental and observational approaches to study the underlying mechanisms (“process”). The basic hypothesis to be tested assumes a deterministic vertical structure in the epiphyte community, but a large degree of ecological equivalence among the species comprising different vertical guilds.

植物群落结构和动态背后的机制是激烈的争论。两个相反的概念强调利基解释，或者是分散（=中性）过程。拟议的项目利用了原始的巴拿马低地森林中约有13,000个血管附生植物的完全普查的独特机会，该森林于2002年完成。通过使用塔式起重机到森林的所有阶层，该项目将直接记录该社区的动态，并在时间和空间（“模式”）中使用实验和观察的方法，以实验和观察的方法。要检验的基本假设假设附生植物中的确定性垂直结构，但是在完成不同垂直行会的物种中，生态等效很大。
