a Density and b relative contribution of each copepod fraction (>300 and <300 μm) to total density. c Biomass and d relative contribution of each copepod fraction (>300 and <300 μm) to total biomass of copepods for summer 2000, 2001 and 2003. Circle size is proportional to the absolute values of density and biomass. The central black dot indicates the location of the stations in summer 2003
