[Question] What is the reason for the small proportion of plants?

The low plant occupancy reflects the fact that the survey was conducted in the summer and the difference in generation time between taxa.In spring, spring phytoplankton blooms occur in the subarctic zone, and plant occupancy increases. On the other hand, the generation time of plants is short, and blooms converge in 1 to 2 months. The generation time of multicellular zooplankton (especially copepods with a dormant period) is long, extending over a year. Therefore, the proportion of multicellular zooplankton is high in summer.
