Abstract. To a certain degree, Eastern Boundary Current (EBC) ecosystems are similar: Cold bottom water from moderate depths, rich in nutrients, is transported to the euphotic zone by combination of trade winds, Coriolis force and Ekman transport. The resultant high primary production fuels secondary upper pelagic nearshore zones, but where O2 exchange restricted, it creates oxygen minimum zones (OMZs) at shelf slope (Humboldt Benguela Current) or depths (California Current). These hypoxic...

ABSTRACT Various morphotypes of large filamentous bacteria were isolated through micromanipulation from sulphidic sediment mats in the Bay Concepción, central Chile. This study employed DNA amplification, whole‐genome sequencing and bioinformatics analyses to unveil taxonomic genomic features previously unidentified bacteria. The results revealed several novel genera, families species, including three specimens belonging Beggiatoales (Beggiatoaceae family), five Desulfobacterales...

Newly settled individuals and juveniles of several benthic decapod crustaceans spend their first months or years in nursery habitats different from those the adult population.It was unknown if this case for squat lobster Pleuroncodes monodon, an exploited crustacean which inhabits continental shelf off central Chile, 2 populations exist, larger Achira (35' 10' S to 36' 15' S) smaller Biobio (36' 35' 50' S).We report here presence a large area species, connecting both populations; habitat is...
A benthic megafaunal study off Concepción Bay, central Chile (36°32'S, 73°W), provided abundance and bathymetric distribution data of the newly recruited squat lobster Pleuroncodes monodon (Decapoda, Galatheidae). The megafauna was surveyed 8 times between July 1991 April 1992, with an Agassiz trawl at depths 40, 64, 96 m along a transect across continental shelf. Recruits P. (carapace length (CL) 3-10 mm) were first sampled in all depth strata early March, then April. density (1 ind/m2)...
Gunnar Thorson, a direct disciple of C.G. Joh. Petersen, the father quantitative sub-littoral ecology, in his seminal work 1957, had come to conclusion that - "the same types bottom are everywhere inhabited by series 'parallel' animal communities, which different species, genera, replace one another as "characterizing species". Despite this, however, Thorson himself was not content with the, at time, scanty data from tropical regions. This fact leads him stimulate further sampling taking...
