Geographical distribution and seasonal and diel changes in the diversity of calanoid copepods in the North Atlantic and North Sea
International audience This paper examines spatial distribution in the pelagic diversity of calanoid copepods in the North Atlantic and the North Sea, taking into account changes at seasonal and diel scales. Based on 40 yr of sampling by the Continuous Plankton Recorder (CPR) survey, the diversity (...
