Association with Cystoseira dubia

Description (English)

This association characterised by the brown alga Cystoseira dubia occurs on hard substrata subject to weak hydrodynamics and relatively strong sedimentation. The association was described with Nitophyllum tristomaticum, Peyssonnelia rubra, Ceramium bertholdii and Kallymenia patens. According to Giaccone, only C. dubia, N. tristomaticum and K. patens are characteristic species. Three vegetal strata can be made out in the population: a raised stratum with various scattered Cystoseira (C. spinosa, C. zosteroides) and Sargassum (S. acinarium, S. vulgare); a very dense intermediary stratum with C. dubia, rich in epiphytes, and a crust-forming stratum of calcareous algae. A very rich fauna made up of bryozoans, molluscs and polychaetes lives in these different strata.
