| The species composition and biomass of coralline algae around three (Uljin, Wolseong and Gori) nuclear power plants on the east coast of Korea were investigated seasonally from February 1997 to October 2006. As a result, 13 species of coralline algae were found during the past ten years. Among them, Corallina pilulifera, C. officinalis, Amphiroa zonata and Pneophyllum zostericolum were common species that occurred more than 50% in frequency during the study period. Species number of coralline algae were between 10$sim$12 species at the breakwaters near the outfalls of power plants and 8$sim$12 species at the control area, and differences in species composition were not observed among study sites. Seasonal fluctuations of mean biomass were 0$sim$2,530 g dry wt m$^{-2}$ and dominant species in biomass was Corallina pilulifera at all the study sites. The breakwaters of power plants generally had a greater coralline algal biomass than the control area. Biomass proportions of coralline algae at the breakwaters of power plants were also higher than those at the control area. At the Uljin sites, particularly, biomass of coralline algae showed greatest in summer and biomass proportion showed highest during the summer season. Differences in the spatio-temporal patterns of coralline algae around three nuclear power plants on the east coast of Korea were presumably due to the regional temperature variations. |
