Table 1. General linear model results for zooplankton grazing, production and community composition in water and sediment traps, and linear mixed model for biomarkers.
Time period is heatwave, and post-heatwave; the control was not treated with increased temperature. NS = not significant, CR = clearance rates, IR = ingestion rates, D = day. As random factor (RF) in LMM was used 1 | mesocosm enclosures.
