Table 2.

Mantel and Partial Mantel tested Spearman correlations between geographic distance, collection depth, environment, and beta diversity.

Tests were performed using all samples, and samples from different months, respectively. Correlations are shown in this table. Bold correlations were corrected by Benjamini-Hochberg multiple tests when the value of p was less than 0.05. The environment was calculated as the Euclidean distance of the physicochemical parameters.
