It has been already observed that some part of the Arctic are experiencing a two bloom regime. It is most like due to environmental changes. Nevertheless, taking such a trait might help to show that a system with diapausing species is predisposed to present a double bloom system. Additionally, here one of the reason only one metazoan is surviving is because the others were not synchronized with their preys. Even for the species that survived, there can be dramatic variation in its community biomass when there is a slight miss-match. This would explain why there is a strong variation in the copepods stocks in nature
