FIGURE 5 Correlations between changes in taxonomic and functional similarities of fish assemblages (b). Black circles indicate the results from 1,378 pairwise assemblages. The Pearson correlation (r ) and significance (P value) of the Mantel tests are provided in each quadrant. Each quadrant represents a different combination of taxonomic and functional changes of fish assemblages (a): (I) first quadrant, (II) second quadrant, (III) third quadrant, and (IV) fourth quadrant
