Spearman Rank Correlation (BEST Bio-Env analysis) between echinoderm community structure and 14 main environmental variables (see Table 1 and text for details and abbreviations).

Analyses were based on Theta dissimilarity of taxa on the ecoregion scale correlated with environmental variables on the ecoregion scale for A. echinoderm assemblages from 16x quadrat collections; and B. echinoderm assemblages from 100x quadrat collections. Best variable combinations yielding the highest correlation coefficient are listed. In addition, correlation coefficients of the single best variable are listed.
