Absolute numbers of all Spumella-like flagellates (a) and of their three most abundant subclusters—Pedospumella, Spumella-like cluster D and Cluster E2 (b–d, respectively) in treatments amended with different bacterial strains at times t₃₇ and t₆₃ compared with control treatment. These data are based on the relative proportion of these subclusters within the target protistan groups (Figure 5 and Supplementary Figure 3) related to total HNF numbers (Figure 3). Note different y axis scaling for c, d. Values are means for triplicates; error bars show s.d.. For further details regarding the bacterial strains see text to Figure 1 and Table 1.
