Los cambios en la estructura de las comunidades bentónicas están estrechamente relacionados con los factores ambientales. Para poder interpretar los posibles cambios asociados con los impactos antropogénicos, es necesario determinar la influencia de los cambios naturales. El objetivo de este estudio fue caracterizar y clasificar las agrupaciones de poliquetos que habitan los fondos blandos no contaminados del Mediterráneo español, así como su relación con los factores ambientales. Se muestrearon 13 localidades entre los 9 y 31 m de profundidad, de 2004 a 2006. La aplicación de técnicas multivariantes demostró que la estructura de las agrupaciones de poliquetos observada en 2004 fue consistente a lo largo del tiempo, detectándose correlaciones entre los poliquetos y los factores ambientales. El área de estudio comprende cuatro tipos de comunidades que se caracterizan, principalmente, por las agrupaciones de poliquetos, los tipos de sedimentos y la profundidad.
Changes in benthic community structure are strongly related to environmental factors, and we need to determine how these natural changes occur in order to interpret the possible changes associated with anthropogenic impacts. The aim of this survey was to characterize and classify the polychaete assemblages inhabiting unpolluted soft bottoms in the Spanish Mediterranean in relation to environmental factors. Thirteen localities were sampled at depths between 9 and 31 m, from 2004 to 2006. Multivariate techniques showed that the structure of polychaete assemblages detected in 2004 was consistent over time and correlations between polychaetes and environmental factors were detected. The study area comprises four kinds of communities mainly characterized by polychaete assemblages, sediment types, and depth.
