By reducing the top-down control of some zooplankton functional species on some phytoplankton functional species, Calanus like metazoan allow the primary producers to have a small second growth period. By eating this zooplankton functional species the metazoans are increasing the recycling of nutrients such as nitrogen. Since they are supposed to have an increase nitrogen excretion by synthesizing lipids, there should be more nitrogen given back into the water column. This has been hypothesized by the Lipid Shunt by Jonasdottir et al. (2015) where diapausing individual stack up carbon via lipid bringing it at depth while leaving nitrogen at the surface. But, with the functional trait of diapause, calanus like metazoans are feeding on the zooplankton only during a short period. Then the addition of this trait reduces the quantity of dissolved and particulate nutrients excreted by the metazoans into the system.
