Abstract: | A brackish lagoon near Marseilles now receives an erratic inflow of fresh water. The fauna and flora were studied before and after the construction of a canal which introduces the fresh water. Instead of the expected change from a marine-dominated to a brackish biota, a general impoverishment has resulted. Increasing urbanization and industrialization of the area is causing extensive deterioration of the coastal environment of which this lagoon forms a part. |
