Spearman's rank correlation coefficients and slopes of linear regressions between the redundancy of a function (DS functional classification scheme) and species diversity.

The levels of significance (P-values) are indicated for both Spearman's correlations and linear regressions. ns: not significant; *: PPP本研究对斯皮尔曼相关系数（Spearman's correlation）与线性回归（linear regression）均标注了显著性水平（P值，P-values）。其中，ns代表无统计学显著性（not significant）；*代表PPP。
