Respiration in marine zooplankton-the other side of the coin: CO2 production
International audience We measured respiratory release rates of CO, 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, amphipo...
