Respiration in marine zooplankton—the other side
We measured respiratory release rates of CO2 from various taxonomic groups of zooplankton during three cruises in winter, spring, and summer in the North Atlantic Ocean. Zooplankton species collected comprised different species of thaliacea (salps), mollusc thecosomes, amphipod hyperiids, copepods,...
