The respiration was not taken into account in the previous studies using DARWIN (even though it was present in the code). Here we based our respiration rate following the size-dependant relationship given by Moloney et al. 1989 for zooplanktons. We selected the values from Ikeda and Motoda 1978 and calibrated the a (going from the original values of 15 pgC to 12 pgC, table 1). In order to modify the less possible the model, we decided to use only a basal respiration rate (not taking into account any active respiration related to grazing or avoidance). This basal respiration rate was modified once the individuals went into diapause. Their respiration rates were reduced because they are supposed to rely only on their lipid reserve while having a reduced metabolism. In their paper, Maps et al. (2011) showed that the dormancy respiration can be from ¼ to ⅕ of the active respiration. In addition to this metabolic changes related to the diapause dynamic, we also added an active seasonal vertical migration.
