Deviating events calculated using (A) 16S rRNA metabarcoding data at the ASV level and (B) flow cytometry fingerprinting data collected from the same samples. Note: CWSslow, CWSfast and IWSfast refer to bulk water collected outlets samples and numbers 1, 2, and 3 denote the repetition of the experiment. All the samples were arranged in sequence of the sampling time of each experiment. The y-axis contains values of the difference of the Bray-Curtis dissimilarity of the outlet samples from the threshold, and only positive values indicating deviating events are shown. A threshold is set using the average of inflow Bray-Curtis dissimilarity plus 3 times the standard deviation, following the approach of Favere et al.32. The Bray-Curtis dissimilarity that was assigned to a sample was calculated as the average of the Bray-Curtis dissimilarities between that sample and the inflow water samples of the same date.
