| The impact of pollution on the macrobenthos was studied through a seasonal cycle by analysis of samples taken at 34 stations in the different basins of Algiers harbour (Mustapha, Agha and Vieux Port). Physical and chemical characteristics were measured in the water column (temperature, salinity, seston, dissolved oxygen) and sediment (pH). The faunistic composition of the stations was assessed according to the ecological significance of species or groups of species as determinants of pollution. There were close correlations between the physical and chemical characteristics at che stations and the spatial distribution of species and species assemblages. Seasonal variation in populations was most marked in Mustapha basin, less noticeable in Agha and weak in... |

| Le Ministère de l’Ecologie, de l’Energie et de la Mer a confié au Service du Patrimoine Naturel (Muséum National d’Histoire Naturelle), en lien étroit avec les acteurs de la recherche scientifique, la coordination d’un projet sur l’évaluation de la sensibilité des habitats benthiques aux pressions d’origine anthropique. L’objectif de ce travail est de qualifier la sensibilité générique des habitats présents en France métropolitaine pour aider à l’orientation et à la priorisation de mesures de gestion (pour des activités actuelles ou futures), adaptées aux enjeux de conservation, afin de respecter les objectifs d’atteinte ou de maintien d’un ECF (DCSMM) ou BEE (DHFF). Ce travail permet également de mettre en évidence les habitats et/ou les pressions pour... |

| Changes over a period of thirty years in a circalittoral mud community (% silt greater than or equal to 75) in the Gulf of Fos (French, Mediterranean coast) have been followed at three sites spaced along a transect NNW-SSE at depths of 15, 35 and 70 m. The results clearly show how the macrobenthic community at the three sites has been influenced by the construction of the port of Fos, notably as a consequence of sediment suspension during the dredging of the docks and the access channel, but also due to the dumping at sea of dredged material (more than 100 x 10(6) m(3) were dredged, about a quarter of which was dumped at sea, at depths of 30 to 60 m). The grouping of the samples taken before, during and after the development of the port (1963-1964, from... |
