Temperature norm
In the model, ambient temperature affects both protist and copepod uptake, respiration, clearance, and ingestion rates. Serra-Pompei et al. (2020) represent the temperature dependency as a Q10. In the present study, we follow the approach and use an environmental trait in the form of a temperature norm (Figure 1, and Supplementary Materials). Groups can only grow within the temperature range of their norms (Figure 1).
