Biocenosis of Mediterranean lower mediolittoral rock

Description (English)

The lower horizon of the mediolittoral rock results from the coming together of three essential factors: presence of waves, irregular variations in atmospheric pressure, and wind and tide when present. The constant humectation, greater than in the higher horizon, is the dominant factor, followed by light. Its size depends on the morphology of the substratum and
