摘要

Composition, spatial distribution, dominance, ecological diversity and evenness of crustacean macrofoulers were analyzed in the Veracruz coral reef system, southwestern Gulf of Mexico. Three test sites were established during May-June 2006 based on their distance from the shoreline and the influence of sewage discharged into the coral reef system. Artificial panels were submerged in Hornos, Pajaros and Blanca reefs for a month. The specimens collected represented 33 species, 27 families and 6 orders of crustaceans. One new record and nine geographic range extensions of amphipod species were documented. Barnacles, amphipods and isopods were the dominant foulers according to abundance and settlement strategies, with differences in species, genera and families among test sites. There were dominance, species richness and ecological diversity gradients of crustacean macrofoulers from Hornos to Blanca based on distance from the shoreline, sewage discharges and the influence of hotels and the Port of Veracruz with respect to the Veracruz coral reef system. The influx of sewage to the reef system has apparently caused a reduction in species richness and ecological diversity, an increase in the dominance of a few macrofoulers and morphological changes in gammarid amphipods.
