Figure 2 exhibit the migration pattern of the two Calanus like functional species that succeed to have a stable pattern. The dates are the simulation dates and do not represent real life data. In figure 2A, exiting mid-May/mid-June and going back into diapause in late September/mid-October, the first metazoan functional species takes five months to accumulate enough lipids to survive during the winter. In figure 2B, exiting in late-June/mid-July and going back in late-August/mid-September, the second metazoan functional species takes two month and a half to accumulate enough lipids in order to survive the winter season. Notwithstanding the timing difference between the two species, the maximum biomass at a given depth layer differs from one to two orders of magnitudes.
