Association with Cystoseira amentacea (var.amentacea, var.stricta, var.spicata)

Description (English)

This association is characterised by the brown alga Cystoseira amentacea, Cystoseira amentacea var. stricta and Cystoseira amentacea var. spicata, living in pure, rough waters with strong luminosity. This association, described by Molinier in 1958, forms belts in the photophilous biotopes where there is strong wave action, and whose rocky substratum is subvertical. It is often accompanied by Cystoseira compressa, which may replace it completely in places.
The association with Cystoseira amentacea is represented in the three major areas of the Mediterranean by different geographical varieties of this Cystoseira. The association with Cystoseira amentacea amentacea is endemic in the eastern Mediterranean, whereas Cystoseira amentacea stricta is found in the north-western Mediterranean and the spicata variety in the Adriatic. The three varieties of this Cystoseira are good indicators of the upper limit of the infralittoral stage.
