Heatmap representing the taxonomic classifications of sedRNA samples at each condition. Heatmap of the classified taxa at the taxonomic rank of Class displayed using percentage classification. Darker shades denote higher percentages of classified sedRNA sequence reads to that assigned taxa. Condition As—sediment subsampled onsite and sequenced immediately, Af—sediment subsampled onsite, frozen at − 20 °C and sequenced later and B—sediment stored at 4 °C. Taxa are organised by their phylogenetic relationship. Blue bars indicate where no sedRNA sequences were obtained
