| Abstract |
Samples were taken from June 1985 to May 1986 along an inner-outer transect along the lagoon at 4 stations: 2 stations were located on hard-bottoms and 2 on soft-bottoms. A total of 136,962 individuals of Polychaetes belonging to 35 species were collected. The dominant taxon was Hydroides elegans. Other common species were Nainereis laevigata, Polydora ciliata, Prionospio multibranchiata, Cirriformia tentaculata , Capitella capitata, Ophiodromus pallidus , Podarkeopsis capensis, Syllis gracilis, Neanthes caudata, Schistomeringos rudolphi, Terebella lapidaria and Hydroides dianthus, that can be considered the "core" of the Polychaete community in the Fusaro. Two communities were identified depending on the type of substrate: a soft-bottom community and a hard-substrate one. Both show a variation in species dominances along an inner-outer gradient which, in turn, is modulated by a seasonal trend. |
