Abstract

Benthic samples collected in April, August, and December, 1974 at 23 stations provided quantitative data on the macroinvertebrate communities in the intracoastal waterway and adjacent finger canals at Boca Raton, Florida. Distribution and structure of these communities in relation to station location and sediment type are discussed. The five top-ranked species in this study were the amphipods Ampelisca abdita and Grandidierella bonnieroides, the polychaetes Paraprionospio £innata and Streblospio benedicti, and the bivalve Mulinia lateralis. Three station assemblages based on faunal similarities were designated. Highest diversity (H') and species richness (spp/180) values were found at intracoastal waterway stations. These stations were characterized by sediments with relatively high sand and low organic percentages. Stations located within finger canals were characterized by sediments with high silt-clay fractions, high organic percentages, and low numbers of species and individuals.
