最近，我们提出了使用部分典型的排序分区的物种丰度数据的变化成四个添加剂成分：在当地规模的环境，环境影响的空间成分，纯空间，和一个不确定的分数。通过一个例子，我们展示了如何使用这些分数中包含的信息，以提供更好的洞察数据。特别是，解释是协助单独映射的各种典型的轴，并将它们与可能的生成过程。我们得出一个一般框架的因果解释的各个部分的分区，其中包括环境和生物控制模型，以及历史动态。
We have recently proposed to use partial canonical ordinations to partition the variation of species abundance data into four additive components: environmental at a local scale, the spatial component of the environmental influence, pure spatial, and an undetermined fraction. By means of an example, we show how to use the information contained in these fractions to provide better insight into the data. In particular, the interpretation is assisted by separately mapping the various canonical axes and relating them to possible generating processes. We derive a general framework for the causal interpretation of the various fractions of this partition, which includes the environmental and the biotic control models, as well as historical dynamics.
