The subfamily Exogoninae was studied from samples collected in shallow waters of the fjords and channels Patagonian region Chile. Two new species are described: Exogone yagan n. sp. Erinaceusyllis carrascoi heterosetoides, bidentata perspicax newly reported to Chile, as well genus San Martín, 2005. Parapionosyllis brevicirra, Sphaerosyllis hirsuta Salvatoria rhopalophora, comb., also reported, with latter redescribed. Finally, we redescribe anomalochaeta Antarctica. Most were found inside...
Deep-sea tailing disposal (DSTD) and its shallow water counterpart, submarine tailings (STD), are practiced in many areas of the world, whereby mining industries discharge processed mud- rock waste slurries (tailings) directly into marine environment. Pipeline discharges other land-based sources pollution fall beyond regulatory scope London Convention Protocols (LC/LP). However, guidelines have been developed (Papua New Guinea) to improve management frameworks which companies can operate....
Three new species of the genus Syllis Savigny in Lamarck, 1818, from Chilean Patagonia are described, figured and discussed. The specimens were collected boulders, sediment bottoms, Macrocystis pyrifera holdfasts, inside tubes Chaetopterus cf. variopedatus. patagonica n. sp., is characterized by its color pattern, short, fusiform dorsal cirri, plenty hyaline inclusions, acuminate posterior acicula, compound chaetae with slightly bidentate falcigers. terraeignium has similar chaetae, but...
Acquiring marine biodiversity data is difficult, costly, and time-consuming, making it challenging to understand the distribution abundance of life in ocean. Historically, approaches sampling over large geographic scales have advocated for equivalent effort across multiple sites minimize comparative bias. When cannot be equalized, techniques such as rarefaction been applied biases by reverting diversity estimates numbers samples or individuals. This often results oversampling wasted...
Through an oceanographic cruise carried out between the southern area of Aysén and northern one Magallanes, Canal Trinidad to Smyth (50º00'S, 75º00'W 52º00'S, 73º48'W), 13 collecting stations were made gather biological material record characterizing intertidal biotopes this extended area.A total 19 identified, from which 12 those had been recorded previously at more septentrional areas Aysén; other 6 represented variations in only 1 was described as a new biotope.Among former ones are rocky...
The number of records the genus Prionospio Malmgren, 1867, from deep sea (>2000 m) are relatively few and do not reflect actual occurrence species nor their potential ecological importance. In this paper we describe five new (Prionospio amarsupiata sp. nov., P. vallensis branchilucida hermesia nov. kaplani nov.) all which abundant members deep-sea community. We also two Aurospio Maciolek, 1981 (Aurospio abranchiata A. tribranchiata again common elements abyssal fauna. Two have characters...
The Eastern South Pacific coastal zone is characterized by seasonal and interannual variability, driven upwelling El Niño Southern Oscillation (ENSO), respectively. These oceanographical conditions influence microbial communities their contribution to nutrient greenhouse gases recycling, especially in bottom waters due oxygenation. This article addresses the hydrographic biogeochemical water sediments during 2015. Bottom active communities, including nitrifiers, were studied using amplicon...

Durante el Crucero 16 CIMAR Fiordos realizado entre Estrecho de Magallanes y Canal Beagle (53º11,16'S; 73º24,06'W-55º09'03,92''S, 68º08'27,9''W) se realizó un muestreo intermareal submareal 14 estaciones. Estas muestras obtuvieron manualmente por buceo apnea, en transectas perpendiculares a la línea costa, con orientación sur-este ellas aplicó metodología establecida 15 para caracterización los biotopos costeros.
 Se determinaron 10 marinos que corresponden tres grandes grupos:

The Syllidae subfamilies Eusyllinae, Anoplosyllinae and Autolytinae, as well the incertae sedis genera (Aguado et al ., 2012), were studied from samples collected in shallow water fjords channels Chilean Patagonia. One new species Paraehlersia kawesqar sp. nov. is described. genus Nudisyllis Knox & Cameron, 1970 recorded for first time Chile, while Brachysyllis infuscata (Ehlers, 1901a) Syllides japonica Imajima, 1966 are continental Chile. Finally, articulosa Ehlers, 1897 Epigamia also...
Composition, abundance and richness of the intertidal shallow subtidal (<30 metres) benthic polychaetes are presented.Several coastal fieldworks in fjords, channels islands were undertaken between 2001 2003 relationship with Biodiversity Aysen Project.1.364 individuals a total number 76 taxa belonging to 30 families recorded.The higher species was observed by Spionidae Nereididae nine eight respectively, Platynereis australis (Schmarda, 1861) showing highest dominance across overall sampling...
A quantitative study of metazoan meiofauna was carried out in Valparaiso Bay (33°S 71°W) which is affected by seasonal hypoxia central Chile. The contents bottom water, dissolved oxygen (BWDO), organic carbon, chloroplast pigments and composition stable carbon isotope (d13C) the sediment were used as a measure contribution primary production water column, accumulates sediment. Meiofauna abundances three sampling stations (80-140 m depth) ranged from 2.218 ± 643 to 1.592 148 ind 10 cm-2. Nine...
