Pearson correlations between the relative abundances of ammonia oxidizers and the concentrations of EPS components in the plastisphere and NH₄⁺in seawater. (A-C) Pearson correlations between the relative abundance of the two CMX MAGs and the concentration of polysaccharides (PS), proteins (PN), and NH₄⁺, respectively. (D-E) Pearson correlations between the relative abundance of the two AOA MAGs and the concentration of PS, PN, and NH₄⁺, respectively. Pearson’s correlation coefficients and P values are given in the panels.
