In the Southern Ocean, several zooplankton taxonomic groups, euphausiids, copepods, salps and pteropods, are notable because of their biomass abundance roles in maintaining food webs ecosystem structure function, including provision globally important services. These groups consumers microbes, primary secondary producers, prey for fishes, cephalopods, seabirds, marine mammals. providing link between production, higher trophic levels these taxa influence energy flows, biological production biomass, biogeochemical cycles, carbon flux web interactions thereby modulating functioning ecosystems. Additionally, Antarctic krill ( Euphausia superba ) various fish species harvested by international fisheries. Global local drivers change expected to affect dynamics key species, which may have potentially profound wide-ranging implications Ocean ecosystems services they provide. Here we assess current understanding dominant metazoan within other euphausiid, copepod, salp pteropod species. We provide a systematic overview observed potential future responses changing functional relationships impact them. To support assessments conservation management strategies, also identify priorities research.
