Abstract :
[en] As phytoplankton reflect immediate effects of changes in nutrient inputs in ecosystems, they have been retained by several European legislations to assess the health status of marine ecosystems. Here, we present a new phytoplankton composition index, PPCI Med (Pigment Pressure Composition Index) adapted to the specificities of the Western Mediterranean coastal waters. It uses diagnostic pigments of total phytoplankton measured by HPLC. Only pigments responding positively to pressures (i.e. nutrient concentrations) are considered. The calculation protocol is described, and an evaluation grid is proposed. PPCI Med is designed to be scientifically robust yet easy to implement by stakeholders lacking expertise in phytoplankton biodiversity. PPCI is transferable in other coastal zones if pigments/pressure relationships are established.
