Abstract

The spatial and ecophysiological preferences of the most abundant meiofaunal taxa inhabiting the sandy intertidal areas of NW Spain are characterised using ecological profiles methodology. Eh and water content are the best variables to explain the spatial distribution of most of the meiofaunal taxa. In general, most of the taxa show good agreement between the spatial and ecophysiological preferences, except for shear strength, mean grain size, carbonate, chlorophyll-a and depth. Eh and water content are the environmental variables that best explain the occurrence and densities of the majority of the meiofaunal taxa.
