The current paradigm of plant community assembly relies on a set of processes operating at particular spatial scales. It is assumed that as the spatial scale becomes finer, environmental filtering loses its importance in favor of biotic interactions and neutral processes. Thus, at the very fine spatial scale represented by a rectangular plot of 72.25 m2 in a Mediterranean semiarid dwarf‐shrubland, we ask: (a) are the spatial distributions of individuals of the different species explained by neutral models; (b) are these distributions dependent on above‐ground plant interactions with the dominant species in the community; and/or (c) are they responding to the spatial variation of different soil variables, in a kind of fine‐scale environmental filtering?

地下故事:土壤异质性以及不仅地上植物相互作用,也解释了地中海矮灌木丛中的小规模物种格局

植物群落组装的当前范例依赖于在特定空间尺度上运行的一组过程。假定随着空间尺度的变细,环境过滤将失去其重要性,而有利于生物相互作用和中性过程。因此,在一个由地中海半干旱矮灌木丛中的72.25 m 2的矩形图表示的非常精细的空间尺度上,我们问:(a)中性模型解释了不同物种的个体的空间分布;(b)这些分布是否取决于地上植物与社区中优势种的相互作用;和/或(c)它们是否以一种精细的环境过滤对不同土壤变量的空间变化作出响应?
