Plankton biomass and/or abundance in the ocean are hydro-climatic variables and as such have been demonstrated to reflect environmental changes, as illustrated by already numerous phytoplankton and zooplankton published studies. Being at the base of the food-web and representing a food of importance for numerous species of higher trophic levels, such as fish of commercial interest, the fluctuation of plankton biomass and/or abundance can have significant impacts on the whole trophic food web but also on carbon cycles and nutrient recycling. The intrinsic characteristics of these organisms at the base of the food web, such as small size, short life cycles and distribution over the whole globe, render them particularly interesting in the frame of monitoring programmes and they have a high potential to reflect environmental changes at short and long-term scales in the marine systems.
In practice, the use of total biomass and/or abundance is often favoured over indicators using species, s.....
