Abstract

On rocky shores, sewage discharges can modify natural distribution patterns Of sessile organisms. The impact of sewage On shallow hard substrate assemblages has been assessed along SW Apulian coast (lonian Sea Italy). providing it framework to evaluate the benefits of future sewage displacement to deeper waters. Four locations (three controls and One putatively impacted) were selected and three sites were chosen at each location. Each site was sampled by 10 replicate photographic records. Univariate analyses revealed that the outfall did not affect the spatial distribution of number of taxa, total cover and abundance of some dominant taxa (mostly algae. sponges and bryozoans). The outfall negatively influx seed the natural distribution pattern of filamentous green algae. whilst some algae (i.e. Gelidiales and Colpomenia sinuosa) were exclusively present at the impacted location. Multivariate analyses revealed that the outfall heavily modified the natural pattern of variability in the structure of the assemblage. (C) 2002 Elsevier Science Ltd. All rights reserved.
