Figure 2 Wang (2025): Size effects of protists on bacterial relative abundance and indicator taxa. Effects of protist size on bacteria community composition at the phylum level (A) and genus level (B). Representative bacteria among protists of different categories were selected based on linear discriminant analysis effect size (LEfSe) with an LDA threshold of 3.5; only the lowest taxonomy level of selected bacteria is shown (C). Differentially abundant bacterial taxa (at genus level) in each protist treatment compared to the no-protist control (P−), identified by ANCOM-BC2 (P < .05). Dot size corresponds to the beta coefficient from ANCOM-BC2. In panel C, the genus level of bacteria is shown in italics, the family level is in non-italic with regular font. P- = no-protist control, Ps = protists of the small-size category treatment, Pm = protists of the medium-size category treatment, Pl = protists of the large-size category treatment. Significant differences between different treatments in panels A and B are evaluated by a one-way ANOVA test (P < .05), with different letters above bars (only significant results are labeled) indicating significant distinctions tested through Tukey’s HSD post hoc test (P < .05).
