Linear regression of average multivariate dispersion against sediment redox potential.

A, B and C represent results from presence/absence data; D, E, and F represent results from relative abundance data. This analysis was performed to the different sources of variation: all estuaries together (A, D) and separated (B, E), and for each plot within estuary (C, F).

A、B、C为存在-缺失数据的分析结果，D、E、F则为相对丰度数据的分析结果。本次分析针对不同变异来源设置了三类分析方案：涵盖所有河口的合并分析（对应A、D）、分河口单独分析（对应B、E），以及河口内各单样地的分析（对应C、F）。
