Modificazioni temporali delle biocenosi bentoniche di fondo mobile lungo la costa del Promontorio del Conero (Nord Adriatico)

The soft-bottom biocenosis along the coastal area in front of the Conero Promontory were characterized up to 12 m of depth in 2000 and 2002 to detect possible changes in the community structure. No inter-annual differences were observed at 4 m of depth. A shifting from the unstable bottom biocoenosis to the well sorted fine sand one at 8 and 12 m, instead, was recorded at some sampling sites
