Active excretion was not taken into account for the zooplankton into the previous studies using DARWIN (even though the equation was present into the code). The values used for the size-dependent relationship were extracted from the data set provided by Vanni et al. 2017. We selected the excretion rate of pelagic zooplankton and did a linear regression on the size of these species in order to obtain the size-dependent relationship values given in table 1. The actual values was 0.36 mmol N mmol C-1 d-1. This values appeared too high to have a realistic time for lipid synthesis (few days to reach the diapause-triggering threshold). Since we included every pelagic zooplankton species present in the data set, some of them had very high nitrogen excretion rate compare to a Calanus species (Cladocerans have an excretion rate sevenfold the one of copepods, Vanni et al. 2017). That is why we choose to take one fourth of that rate (9.03e-2 mmol N mmol C-1 d-1 ) that gave a realistic time of lipid accumulation (between 2-4 months depending on the functional species). In line with the current parametrisation of copepods-like metazoans, we changed also the respiration parameters.
