Resumen:
ABSTRACT The variation of the composition of macroalgae assemblages at different taxonomic aggregation was assessed at two different wave exposure conditions on the coast of Mar del Plata, Argentina, at the Southwest Atlantic Ocean. The macroalgae assemblages attached in two sites were compared: an inside Harbor, a sheltered site from the waves, and a wave-exposed site in Playa Grande, a nearby open-beach. The species composition was significantly different between sites. Ulva lactuca, Ulva spp., Corallina officinalis and Gigartinaceae sp.1 were the most conspicuous species in the wave-sheltered site, while Hildenbrandia sp., Ulva lactuca, Ahnfeltiopsis sp. and Ceramium uruguayense were the most abundant species in the waveexposed site. This spatial pattern was similar throughout the year. The sites were different regarding to species, genera, order and phyla levels. The different assemblage composition founded could be a result of the variation of both waves exposure and water pollution level in the two sites
