Fig. 5: Abundance of single species during periphyton establishment.

Shown is abundance of group A (a), group B (b), and group C (c) eukaryotic species as well as group C prokaryotic species (d) measured at t1 (A 4 days), t2 (AB 18 days), and t3 (ABC 30 days) and grown under different conditions. The conditions correspond to 4 levels of the herbicide terbuthylazine (0, 1, 10, and 100 nM) and 2 different temperatures (17 and 20 °C). Horizontal lines in the black boxes correspond to the average values and the lower and higher limits of the standard deviation (n = 3). Results of the pairwise comparison (post hoc Tukey test) among all treatments for each species are shown in Supplementary Tables 13–15.
