Prey of active Zooplankton duing the polar night

Tildelt: kr 47 999

Diel vertical migration (DVM) is known to be the largest daily movement of organic material, as well as living organisms on the planet. That makes it a key process if we want to understand the pelagic food web and carbon sequestering of the ocean. It is p roposed that DVM happens, due to the attempt of avoiding visuel predators. Contradicting this theory, new studies carried out in the Svalbard archipelago provide unanticipated evidence of both active and synchronized DVM of zooplankton during periods of p olar night. Therefore we need to establish the basic biological foundation behind the behaviours and their wider ecological impacts. We aim to do that by focusing on prey of large migrating zooplankton, and the impact it may influence on the necessity for Zooplankton of performing DVM in polar night.
