FIG 3.

Comparison of the microbial communities between aggregated and free-living groups for each treatment. Differential abundance analysis shows certain phylogenetic groups and ASVs are more abundant in either the >3.0-μm (relative abundance on y axis) or 0.2- to 3.0-μm (relative abundance on x axis) filter size fraction. The 20 most abundant genera are highlighted with all other less abundant genera as well as groups of unresolved phylogenetic affiliation denoted as other. ASVs of interest discussed in the main text are denoted with numbers within the graphs. A 1:1 ratio between the abundance of ASVs on the >3.0- and 0.2- to 3.0-μm size fractions is depicted as a gray diagonal line within the graphs.
