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...

Soft-bottom hydroids (Cnidaria: Hydrozoa) collected in the Ría de Vigo (NW Spain)
Provedor de dados: 16
Autores: Ramil, F.; Ansín Agís, J.; Fernández Pulpeiro, E.
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...

Spatial distribution of bivalve mollusc assemblages in the upwelling ecosystem of the continental shelf of Cabo Frio, Rio de Janeiro, Brazil
Provedor de dados: 104
Autores: Soares-Gomes,Abilio; Fernandes,Flavio da Costa.
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...

Padrões de abundância, riqueza e diversidade de moluscos bivalves na plataforma continental ao largo de Ubatuba, São Paulo, Brasil: uma comparação metodológica
Provedor de dados: 104
Autores: Soares-Gomes,Abílio; Pires-Vanin,Ana Maria Setubal.
The diversity and richness patterns of bivalve molluscs were studied on the continental shelf of Ubatuba (23º38'S, 45º14'W and 23º25'S, 44º51'W) between 15-120 metres depth. The samples were taken with a rectangular dredge and a beam trawl. The results showed higher values of richness, diversity and evenness for inner shelf (from coast to nearly 50 m depth) and greater values of abundance for outer shelf (from 50 to around 120 m depth). This pattern might be due to the higher instability of the inner shelf, which is influenced by the seasonal intrusion of the South Atlantic Central Water (SACW) and the occurrence of cold fronts. Sanders' rarefation curves, distribution and abundance curves and DIMO model were used and the results compared. The Qinghong's...
