Response of ecological indices to nutrient and chemical contaminant stress factors in Eastern Mediterranean coastal waters

⿢Primary production indices most sensitive to particulates and nitrogen.⿢Secondary production indicators (benthos) most sensitive to phosphorus.⿢A physicochemical status indicator firstly applied in Eastern Mediterranean.⿢Decision tree successfully assessed major stress factors⿿ impact.⿢Macroalgae reflected the impact of multiple pressures on the coasts.
