THE INFLUENCE OF TEMPERATURE AND FOOD QUALITY ON MESOZOOPLANKTON RESPIRATION
participant Through their physiological processes, mesozooplankton can contribute significantly to the marine biogeochemical cycling of carbon and nitrogen. However some of these processes have been poorly parameterised in ecosystem models. Respiration in particular has been measured in terms of bas...
