Resumen:
ABSTRACT. The aim of this study was to investigate the patterns of nematode diversityand community structure in San Jorge Gulf, Argentina, in order to improve knowledgeof this key group of organisms. Free-living marine nematodes were sampled at 13 stationsin February 2014 during an expedition aboard R/V Coriolis II. We found a total of188 species (101 of which were new to science) belonging to 98 genera. The statisticalresults indicated the presence of three different assemblages of free-living marine nematodesdistributed spatially in three distinct zones in the gulf: the central part, the outerthermal front at both sides of the entrance, and the south thermal front area. Diversityincreased from the coast to the entrance of the gulf, and the highest diversity was foundin areas with coarser sediment. Sediment and salinity were the environmental parametersthat best matched nematode community distribution.
