espanolLas asociaciones de macrobentos con presencia de mitilidos de la bahia San Julian (Patagonia austral, Argentina) fueron muestreadas durante el verano de 2007 para conocer su estructura, diversidad y distribucion, y para determinar su relacion con diversos factores ambientales. El estudio fue realizado en 3 localidades con diferentes tipos de sustrato y distinta pendiente. El muestreo en cada localidad se realizo en una transecta abarcando diferentes niveles del intermareal y del submareal somero. Se hallaron un total de 46 especies pertenecientes principalmente a moluscos (20), crustaceos (12) y poliquetos (10). Se identificaron 3 asociaciones principales: la asociacion Platynereis-Clunio-Darina se distribuyo en el nivel intermareal superior de sustrato fangoso y pendientes suaves y presento los valores mas bajos de numero de especies, de diversidad especifica y de abundancia de individuos; la asociacion Mytilus-Perumytilus se distribuyo en los niveles intermareales medio e inferior en sustrato rocoso o en sustrato fangoso con abundantes elementos de soporte y pendiente media; presento diversidad especifica intermedia y la mayor abundancia de individuos; la asociacion Aulacomya-Exosphaeroma presento el mayor numero de especies y la mayor diversidad, pero baja abundancia de individuos, encontrandose relacionado a sustratos rocosos o sustratos fangosos con elementos de soporte y baja pendiente del submareal superior. La riqueza especifica y la diversidad de estas asociaciones aumentan desde el nivel superior del intermareal hacia el submareal, posiblemente por efecto de un gradiente complejo de estres, principalmente ocasionado por la desecacion y exposicion a temperaturas extremas. EnglishThe macrobenthic assemblages with mytilids of San Julian bay (Southern Patagonia, Argentina) were sampled in summer 2007 to know its structure, diversity and distribution, and to determine their relationship to different environmental factors. The study was conducted in 3 locations with different types of substrate and slope. Sampling at each site was performed in a transect to cover different levels of intertidal and shallow subtidal. A total of 46 species belonging mainly to molluscs (20), crustaceans (12) and polychaetes (10) were found. Three main macrofaunal assemblages were identified. Platynereis-Clunio-Darina assemblage was distributed in the upper intertidal of muddy and gentle slopes substrate, and had the lowest values of number of species, diversity and abundance of individuals. The Mytilus-Perumytilus assemblage was distributed in the middle and lower intertidal levels in rocky substrate or muddy substrate with abundant support elements and medium slope. This assemblage presented intermediate values of diversity and greater abundance of individuals. The Aulacomya-Exosphaeroma assemblage had the highest number of species and the greatest diversity, but low abundance of individuals, being related to rocky substrate or muddy substrate with support elements and low slopes in the upper subtidal. Species richness and diversity of these assemblages increases from the upper intertidal to subtidal, possibly because of a complex gradient of stress, mainly caused by desiccation and exposure to extreme temperatures.
