Se analiza la distribución batimétrica de los foraminíferos bentónicos en el área de canales y fiordos, al sur del estrecho de Magallanes, (52-56°S), Chile. Para ello se estudiaron 34 muestras recolectadas en la zona de plataforma (35 - 650 m), durante la expedición CIMAR 3 FIORDOS (1998), organizada por el Comité Oceanográfico Nacional (CONA). Se obtuvieron 21.190 ejemplares los que fueron clasificados en 169 especies; sólo el 8,3% de las especies alcanzaron una representación superior al 2%, por lo cual, se seleccionaron 47 especies, según su abundancia por tramo, para verificar su distribución. Se reconocieron tres asociaciones: a) de aguas someras (0-150 m); en la porción más superficial (50 m) dominaron Buccella frigida, Buliminella elegantissima y... |

La composición de las comunidades foraminiferológicas en sedimentos superficiales de aguas menores a 30 m y mayores a 80 m del fiordo Comau, golfo de Ancud, Chiloé, Chile, aplicando SIMPER, ANOSIM, MDS y análisis de Cluster, muestran una alta diferencia y distinguen dos comunidades: una de aguas someras, en la cual las especies que más contribuyen a la similitud de las muestras son Ammonia beccarii (87,6 %) y Buccella peruviana (4,48 %) y otra de aguas más profundas, en la cual, las especies que más contribuyen a su individualización son: Uvigerina bifurcata (24,8%), Bulimna notovata (21,8%), Bulimina patagonica (14,42%), Nonionella auris (10,11%), Globocassidulina minuta (7,37%), Nonionoides grateloupi (3,94%), Quinqueloculina seminula (3,44%), Buccella... |

The present study describes for the first time the spatial distribution of five macrourid species throughout the Mediterranean Sea and analyses depth, geographical and time-related trends regarding their abundance, biomass and mean fish weight. The data were collected as part of the MEDITS annual bottom trawl survey carried out by several European Mediterranean countries from 1994 to 2015, using the same standardized gear and sampling protocol. The most represented species in terms of abundance and biomass was Coelorinchus caelorhincus. The bathymetric trend was different for each species. The shallowest occurring species was C. caelorhincus, followed by Hymenocephalus italicus and Nezumia sclerorhynchus, while Nezumia aequalis and Trachyrincus scabrus... |

This study focuses on the ophiuroids collected during the Programme of Evaluation of the Living Resources of the Exclusive Economic Zone for the Brazilian coast (REVIZEE), South Score/Benthos, in the states of Rio de Janeiro (Ilha Grande Bay), São Paulo, Paraná, Santa Catarina and Rio Grande do Sul (Tramandaí) (24° 07,113' S and 29° 48,500' S; and 43° 46,759' W and 49° 06,800' W). Samples were collected on the continental shelf and slope (60-810 m) using the following equipment: van Veen, box corer and a rectangular dredge. Individuals were identified, measured and photo-graphed under a stereomicroscope and a scanning electron microscope. Growth series of the species that contributed with more than 10 individuals were analysed. A total of 5044 individuals... |
