Drivers of viral functional variation between sponge species. To identify key functional differences in viromes of each sponge species, the R package mvabund was used to perform univariate tests on Swiss-Prot keyword enrichment frequency values. Heatmap shows all significant differences in Swiss-Prot keyword enrichment frequency data (P value ≤ 0.02), adjusted to account for coverage of the source contig within individual viromes
