Why do the two most abundant copepods in the North Atlantic differ so markedly in their die1 vertical migration behaviour?
A total of 55 113 plankton samples, collected between 1948 and 1992 in the North Atlantic by the Continuous Plankton Recorder (CPR) survey, were used to show that normal die1 vertical migration (NDVM) behaviour was far more marked in the copepod Metridia lucens than in the copepod Calanus finmarchic...
