Última Structure of the artificial hard substrate assemblages in ports in Thermaikos Gulf (North Aegean Sea) ArchiMer Karalis, P; Antoniadou, C; Chintiroglou, C. The present study describes the hard substrate assemblages established on the concrete blocks of three ports placed in gradually longer distances from the main source of pollution in Thermaikos Gulf. The samplings were performed on a seasonal basis for a 2-year period. The data analysis indicates a clear separation of the assemblages from each port. Evenness and Shannon-Weaver diversity indices were calculated and their values were found to be quite high. This fact, combined with the seasonal pattern that these assemblages hold, reveals stability and a good adaptation of their faunistic components to local environmental conditions. A change due to the construction of a new block functioning as a surge barrier was detectable at the station of N. Michaniona....

During 1985 and 1986, sublittoral communities on hard substrates in the southern Delta area, SW Netherlands, were investigated at 79 stations. The stations were distributed over 20 localities situated in the saline Lake Grevelingen, the Oosterschelde estuary and the SE North Sea. The percentage cover of all sessile organisms were estimated using quadrat sampling techniques; data were processed using cluster analysis. The stations were characterized by the assessment of the most important environmental parameters: available light, hydrodynamics and sediment characteristics. Eight sublittoral communities on hard substrates are described by characteristic and dominant species. Three communities are subdivided into variants on account of differences in...
