“…are also frequently mentioned as being in or around sewage outfalls in the Southern Hemisphere, like B. proboscidea (Dorsey, 1982) and also in California (Dorsey et al, 1983). B. polybranchia was described from an Australian sewage outfall, and is common in the Brachidontes community (see Blake, 1983). López Gappa et al (1990) have found up to 500,000 ind/m 2 of Boccardia sp.…”

SUMMARY: Continuous and short-term disturbances are produced on intertidal Brachidontes rodriguezii mussel beds by the sewage outfall of Mar del Plata, SW Atlantic. The effects on the associated polychaetes living on and between mussels were investigated, in both the spatial and short-term temporal scales. Multivariate methods show that the polychaete fauna was influenced by tidal level, total amount of sediment accumulated between mussels, distance from the sewage outfall, organic carbon of interstitial sediments, and sewage volume before and after the summer season. Environmental variables in the water column fitted with a spatial and temporal organic gradient. Capitella 'capitata' sp. showed typical opportunistic behaviour in relation to organic enrichment, as did Neanthes succinea, both being numerically dominant near the sewage discharge. Cirratulus sp., Caulleriella alata, and Boccardia polybranchia were common at intermediate distances from the outfall. Syllis prolixa, S. gracilis, and Protoariciella uncinata reached their highest abundance at intermediate stations and were characteristic of the control site. Close to the outfall mussel density and dominance is low, and opportunist polychaetes successfully colonize organically enriched interstitial sediments. At intermediate distances from the outfall sediments retained by mussels reach their maximum values, and density of polychaetes is also high. The control station is characterized by monolayered mussel beds and very low diversity of polychaetes. Opportunistic polychaetes increase in response to shortterm increases of sewage discharge during the summer season (November-March).Keywords: polychaetes, intertidal, mussel beds, organic pollution, sewage, spatial and before-after summer season distribution, SW Atlantic. RESUMEN: PERTURBACIONES DEBIDAS A EFLUENTES DOMÉSTICOS EN POLIQUETOS ASOCIADOS A BANCOS DE BIVALVOS DEBRACHIDONTES RODRIGUEZII EN MAR DEL PLATA (ATLÁNTICO SUDOCCIDENTAL). -Perturbaciones contínuas y de corto período de tiempo debidas a efluentes domésticos afectan a los bancos de los bivalvos Brachidontes rodriguezii en Mar del Plata, Atlántico sudoccidental. Se investigaron sus efectos sobre los poliquetos que viven asociados dentro y sobre los bancos, tanto en la escala espacial como la temporal (corto plazo). Métodos multivariados mostraron que los poliquetos estuvieron relacionados al nivel de marea, al total de sedimentos acumulados entre los bivalvos, a la distancia al efluente, al carbono orgá-nico total de los sedimentos y al volumen de descarga antes y después del verano. Las variables ambientales de la columna de agua estuvieron en concordancia con un gradiente de enriquecimiento orgánico espacial y temporal. Capitella 'capitata' sp. mostró el típico comportamiento oportunista en relación al enriquecimiento orgánico, al igual que Neanthes succinea, siendo ambas especies numéricamente dominantes cerca del efluente. Cirratulus sp., Caulleriella alata y Boccardia polybranchia fueron comunes a distancias intermedias del efluente. Syllis...

“…These four species also can be distinguished by the more anterior occurrence of sabre chaetae, which ranges from chaetiger 10 to chaetiger 13 (for L. nuchala this information is lacking in the original description), their shorter caruncles, which never extend further than chaetiger 14, and by their occipital tentacle, which are digitiform instead of rudimentary, except for L. appelloeW that also bears a poorly developed one. A more similar species is L. norgensis (Sikorski 2003 (Hartman 1978;Blake 1983), and the sabre chaetae that appear in chaetigers 11-13 (Radashesky and Lana 2009). On the contrary, the second one do not belong to the same group of species, since it only bears two rows of capillaries in the fascicles of the anterior part of the body (Hartman 1953;Blake 1983).…”

During the Antarctic summers of 2002-2003 and of 2005-2006, the Spanish BENTART cruises were conducted to the Bellingshausen Sea (Western Antarctica), aiming to study its benthic communities, from depths ranging from 100 to 2,000 m. To achieve it, 30 stations were selected; each one was surveyed in such a way that the infaunal, epifaunal and suprabenthic components of the communities were suYciently characterized. As a part of the study, some spionid individuals were identiWed as belonging to a new species of the genus Laonice Malmgren, 1867. The new species belongs to a group within the genus that is characterized by the presence of more than two rows of very numerous capillary chaetae in both noto-and neuropodial fascicles of anterior part of the body. However, it can be readily distinguished from the rest of species within the group by the posterior position in which neuropodial pouches appear (chaetiger 16 or 17) and by the caruncle reaching posteriorly chaetiger 19. In addition, other remarkable features of the new species are the short and triangular occipital tentacle, the rudimentary eyes, the hooded neuropodial hooks Wrst appearing in chaetigers 34-37 and the sabre neurochaetae Wrst occurring in chaetigers 20-27.

“…However, the latter species is described as a strict brackish water species (e.g. Blake, 1983), whereas B. hamata is common in fully marine as well as estuarine conditions (Blake, 1966). There are at least two clear morphological differences (Blake, 1966;Radashevsky, 1993).…”
