Biodiversity and spatial distribution of Polychaeta (Annelida) communities in coral-alcal buildup sediment, Bahia, Brazil

Abstract

This study was undertaken to evaluate the distribution of the polychaete fauna and to verify the abundance of feeding groups of these communities, in an area of coral-algal buildups under influence of two industrial outfalls: the first one spills organic chemical-industrial residues which has been partially treated using microorganisms action. The second spills sulphuric acid, ferrous sulphate and, others previously treated inorganic compounds.
