| 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... |

| Benthic macroinfauna of six beaches near to Guaratuba Bay, Paraná, Brazil were studied in summer and winter of 1994. Sampling stations were distributed along a transect, from upper of the drift line to depths of nearly 3 m behind the first break of the surf zone. Biological and sedimentological samples, slope, wave height and period were recorded. Subtidal samples were collected by scuba diving. The beaches varied from extremely inclined, composed of coarse sediments, to low inclined, composed of fine and very fine sands. The polychaete Scolelepis squamata, was the numerically dominant species in those beaches composed by fine to very fine sand in the subaereal profile. The echinoderm Mellita quinquiesperforata occurred in the last stations of the surf... |

| Six sandy beaches were sampled on the coast of Ancud, Isla de Chiloé, southern Chile (ca. 42º S) with the following purposes: 1) to study community structure and across shore zonation of the intertidal macroinfauna in relation to different beach types, and 2) to analyze how similar or different is the taxonomic composition and community structure of the macroinfaunal assemblages, compared to those inhabiting sandy beaches located further north of Canal de Chacao, the limit between Isla de Chiloé and the mainland coast. Sediment samples (0.1 m², 30 cm deep) were collected (April-May 1998) with plastic cylinders at fifteen equally spaced levels along three replicated transects (separated by 1 m) extending from above the drift line to the swash zone. The... |
