Resumen:
Intertidal macroalgae provide food and shelter for different organisms. The objective of this work was to analyze the bivalves associated with macroalgae. Sampling was carried out in January, May, July, and November 2014, 72 samples of macroalgae and their associated bivalves were manually collected within 400 cm(2) in 2 locations in Guerrero: El Palmar and Las Gatas beaches. The community structure of bivalves was determined from specific richness, composition, abundance, distribution, and community indices: Shannon diversity, Pielou evenness and Simpson dominance. Each macroalgal species (59 spp.) was associated with proposed morphofunctional groups. Macroalgal cover, bivalve abundance and retained sediment were analyzed. Of the total number of individuals (873), 17 bivalve species were recognized. The Shannon index was 2.15 bits/individual. Bivalves were associated with 3 morphofunctional groups of macroalgae. Bivalve abundance and retained sediment decreased by month, while abundance, cover, and sediment decreased with increasing tide level. Studies like this provide important information for understanding coastal diversity, in this case of a tourist area in Guerrero.
