We found an increasing trend in the ZP:PP biomass ratio with significant differences between W and H at the end of the second heatwave (day 21; KW test: chi 2 = 4.77, df = 2, p = .09, H‐W: p = .03, Figure 1e , Table S2 ).

As Chl a still showed a decreasing trend during the first 4 days (days 0–3) in all treatments, likely linked to filling up the mesocosms (e.g., ongoing sedimentation), we excluded this period from the analysis.
Especially towards the end of the experiment, biomass in the W treatment showed a trend of becoming higher than in the other two treatments, but a significant difference was only found between W and H treatments (KW test: chi 2 = 7.65, df = 2, p = .02, W‐H: p < .01) at the end of the second heatwave (day 21, Table S2 ).
