| The recolonization was followed for 3 years from the end of dredging. The species, abundance, biomass curves, and the rank-frequency distributions showed the progressive structuration of the community. The numeral and ponderal cycle of main species and the correspondance analysis explained the main phases of ecological succession: 1) reorganisation of the microbiological processes; 2) constitution of a pioneer community characterized by a peak of opportunistic species (Chaetozone setosa ); 3) establisment of a young and robust community with a high diversity and production; 4) maturation of the community with high interspecific competition; 5) negative evolution caused by high dominance of Melinna palmata . The definition of the stability of such community... |

| Merja Zerga lagoon, located on the Moroccan Atlantic coast, is a site of international value (Ramsar Site) in terms of its ornithological diversity. However, the lagoon is heavily exploited for its clams and fishes. In an effort to further understanding of lagoon ecosystems, and thus to facilitate the management and conservation of their resources, an ecological survey of its benthic component was carried out. Benthos is a valuable food source for birds, fishes and humans. This work involved identifying the macrozoobenthic communities in the lagoon and assessing their spatial distribution. The study was based on monthly sampling of the intertidal zone and seasonal sampling in subtidal zone, over a one-year period. In the intertidal zone, salinity and... |
