| The polychaete composition and distribution within mussel beds were studied in order to assess organic pollution due to domestic sewage in a rocky shore of Mar del Plata (Argentina) during 1997. Four stations and a control site were randomly sampled around the local effluent. Quantitative data on polychaetes, as well as sediment accumulated among mussels and its organic carbon content were measured. Polychaete distribution patterns are related to the organic matter gradient, being Capitella cf. capitata, Neanthes succinea (Frey & Leuckart, 1847) and Boccardia polybranchia (Haswell, 1885) the dominant indicator species close to the effluent. At medial distances, the cirratulids Caulleriella alata (Southern, 1914) and Cirratulus cirratus (Müller,... |

| On the basis of previous studies at 9 degrees N and 13 degrees N East Pacific Rise (EPR) fields, we discuss the general assumption that temperature is a proxy for sulfide in vent fauna habitat. The main conclusion of these works is illustrated here through selected examples. In situ measurements were used to assess the variability of chemical parameters as function of temperature at the scale of fauna aggregations. Over a single vent site, aggregations of mussels or Riftia pachyptila discretely distributed around diffuse vents exhibit, in first assumption, similar sulfide-temperature correlation. In contrast, sulfide is much higher, for a given temperature, in the habitat of alvinellids than in neighboring habitats of Riftia pachyptila. Some consistency in... |

| Aim Deep-sea hydrothermal vents have now been reported along all active mid-ocean ridges and back-arc basins, but the boundaries of biogeographic entities remain questionable owing to methodological issues. Here we examine biogeographic patterns of the vent fauna along the East Pacific Rise (EPR) and determine the relative roles of regional and local factors on the distribution of biodiversity associated with mussel beds along a poorly explored zone, the southern EPR (SEPR). Location East Pacific Rise. Methods A species list of macrobenthic invertebrates along the EPR was compiled from the literature and supplemented with data recovered during the French research cruise BIOSPEEDO carried out in 2004 along the SEPR. Biogeographic patterns were assessed by... |

| The mytilid mussel Mytilus chilensis (Hupe) can form dense beds in sedimentary areas of the inland coast of the Nord-Patagonic archipelagos of the Chilean coast (ca. 40-43° S). During the autumn of 2002, we collected replicated samples at five intertidal stations in Panitao (Golfo de Reloncaví) ordered along a transect parallel to the low tide level and extended from the center of the bank (stations one and two with 100 and ca. 25 % of mussel cover, respectively) to the bare sediments of the intertidal (stations 3, 4 and 5, without mussels). The macroinfauna was numerically dominated by Polychaeta, Oligochaeta and Crustacea Peracarida. The total number of species collected was 14, being the most abundant the polychaete Perinereis vallata, oligochaetes from... |
