Ecomorphosis of striped Posidonia oceanica meadows

Description (English)

The Posidonia oceanica striped meadow develops between 0,5 and 3 meters down. It appears as fairly narrow (1 to 2 m wide) ribbons that are up to several dozen meters long, either rectilinear or winding but rarely ramified. The ribbons are separated by stretches of dead matte colonised by a mixed lawn made up of Cymodocea nodosa and Caulerpa prolifera. Cut into sections, the ribbons are asymmetrical with a little drop of matte on one side and a gentle slope on the other. The ribbons are dynamic structures, moving parallel to each other in the face of currents at a speed of some ten centimeters a year.
