The influence of dispersal on community functioning (A), taxonomic (B) and phylogenetic diversity (C).

<p>Community functioning is assessed as per cell bacterial production (A), local richness of the bacterial community estimated by Chao1 (B), and average phylogenetic distance between bacteria in a community estimated as standardized effect size of MPD (C) for each lake (1–6) in relation to dispersal rate (I–IV). Error bars are standard errors of within treatment replicates in (A and B), and standard deviations calculated from 100 single trees in (C). No replicates were available for dispersal rate IV in lake 3 in (B). Lake 6 is missing in (B) and (C) because DNA could be extracted from dispersal rate I only. Bars with different letters denote significant differences between dispersal treatments within one lake, assessed form Tukey’s post-hoc test in one-way ANOVAs.
