But in our case, even though we observe a change of phenology for some species, the Figure 6 indicates that the implementation of the diapause trait do not have significant impact on the total biomass of phytoplankton and has but a small impact on the zooplankton total biomass. For the phytoplankton, this could highlight again the main bottom-up control of the primary production. For the zooplankton, it is mostly due to the fact that our metazoans only feed on a few zooplankton species (Figure 5). Additionally, the most succeeding metazoan functional species (1635µm ESD) reaches the surface after that its prey biomass peaked. So it should not have an impact on the maximum production of its prey.
