Résumé :	This study concerns two paralic ecosystems, Diana and Urbino lagoons (Corsica). The main aim is to determine the distribution of foraminiferal populations in function of the features and functioning of these ecosystems. The distribution of foraminiferal populations is studied thanks to different methods of populations study (specific richness, density, Fisher diversity index, factorial analysis of correspondences). The distribution of relative abundance of the characteristic species is shown in each ecosystem. The results obtained in Diana lagoon show a global organization of foraminiferal populations. We observe, like in paralic ecosystems studied up to now, a decrease of densities and specific richness, from the areas under marine influence to the more confined zones. Urbino lagoon does not present a such organization and is distinguished by the composition and the distribution of its populations that seems to reveal a more marked confinement in this basin.
