Abbreviations: BD, buoyant density; OTU, operational taxonomic unit. For all OTUs exhibiting a BD shift, see Supplementary Table S1 for abundance and shifts in BD. The ‘% total' refers to the percent of total sequences or percent of total OTUs per size fraction. ‘% total per taxon' refers to percent of total sequences per taxonomic group.
