Etude de la phénologie de la reproduction de la Rhodophyceae Palmaria palmatale long des côtes françaises de la Manche
Phenological study of the reproduction of the Rhodophyceae Palmaria palmata along the French coast of the English Channel. In the rocky, intertidal level of the North Atlantic coast, Palmaria palmata is in terms of biomass, one of the most important Rhodophyceae. This economically interesting seawee...
