Spearman rank correlation coefficients calculated between all the diversity indices.

All correlations are significantly different from zero (with p<0.01), except for underlined values. The Spearman coefficient distribution under null hypothesis was approximated by a normal distribution with mean equal to 0 and standard deviation equal to 1/√ (n–1). Codes of diversity indices are given in Table 1.

除带下划线的数值外，所有相关系数均与0存在显著差异（p<0.01）。零假设下的斯皮尔曼（Spearman）相关系数分布采用均值为0、标准差为1/√(n−1)的正态分布进行近似。多样性指数的代码详见表1。
