| This study aims to describe the patterns of soft bottom macrozoobenthic richness along French coasts. It is based on a collaborative database developed by the “Réseau des Stations et Observatoires Marins” (RESOMAR). We investigated patterns of species richness in sublittoral soft bottom habitats (EUNIS level 3) at two different spatial scales: 1) seaboards: English Channel, Bay of Biscay and Mediterranean Sea and 2) 0.5° latitudinal and longitudinal grid. Total observed richness, rarefaction curves and three incidence-based richness estimators (Chao2, ICE and Jacknife1) were used to compare soft bottom habitats species richness in each seaboard. Overall, the Mediterranean Sea has the highest richness and despite higher sampling effort, the English Channel... |

| Thirty-one hydroids species, living on the sublittoral soft-bottoms, are reported from the Ría de Vigo, representing one third of the species currently known, from the Ría. Twenty-four are Leptomedusae and only seven are Anthomedusae. The identifications of Campomma hincksi, Cosmetira pilosella and Laodicea undulata, based only on the hydroid stage, are discussed. The report includes one species that could be identified only to generic level as well, and also a description of the previously unknown male gonotheca of Halecium liouvillei. Five species, Merona cornucopiae, Hydractinia echinata, Lovenella clausa, Opercularella spec, and Laomedea angulata, were collected exclusively from soft bottoms that seem to be their typical habitat. Analysis of... |

| Bivalve mollusks of the continental shelf of Cabo Frio upwelling ecosystem were sampled monthly from February 1986 to February 1987 along a 30 to 60 m depth gradient. Mactra petiti Orbigny, 1846, and Tellina gibber Ihering, 1907 were constant species in 30 m; Nucula puelcha Orbigny, 1846, Adrana patagonica Orbigny, 1846, T. petitiana, T. gibber, and Corbula patagonica Orbigny, 1846 in 45 m; and N. puelcha, T. gibber, C. patagonica, and C. caribaea in 60 m. The number of rare species was similar along the depth gradient, ranging from six to ten species. The number of common species was higher in 60 m than in 30 m. Some species showed a continuous distribution but changed the frequency and abundance along the bathymetric gradient. The mean density was higher... |
