Heatmap of the top 20 organisms assimilating labelled carbon, based on number of labelled proteins identified for each organism to each sampling time (4 h, 6 h, 8 h, 12 h, 24 h, 36 h, 48 h, and 60 h). Colour intensity refers to the scale (0–100). Primary and secondary degraders were predicted based on isotopic profiles (see “Discussion”)
