Última Modification de l'équilibre démographique de la meiofaune dans les lagunes aménagées de Certes ArchiMer Castel, J.; Lasserre, P.. Monthly sampling for a 2-year period allowed comparisons between the communities of meiofauna living in fish ponds ("reservoirs a poissons de Certes") and those inhabiting a contiguous tidal pool ("lac de tonne"). Nematods and copepods constitute the bulk of the meiofaunal populations. The community structure of co­pepods is considered in detail.The communities of copepods are clearly separated between the two areas. In terms of abundance, diversity and species persistence, the meiofauna is more stable in the intertidal pool than in the fish ponds. When the seasons are well marked, the community structure of the cope­pods in the fish ponds is nearly equilibrated in spring, with a maximum of diver­sity in May-June. During high eutrophication periods, in...

Specific composition and distribution of the zooplankton in Arcachon Bay varie along a salinity gradient from oceanic to neritic and lagoonal condi­tions. A peak of density and biomass is recorded in spring due to an increase of holoplanktonic species as well as larvae of benthic Invertebrates. A second maxi­mum of abundance is observed in autumn. The community structure of copepods and polychaets larvae is considered in detail. The diversity (Shannon index, Sanders's rarefaction) decreases from the mouth of the Bay to the inner neritic water mass. Demographic parameters indi­cate that the populations structure is affected by the salinity gradient. Biomass increases significantly from the oceanic water to the inner neritic water mass while the species...
