The seaweed community at Hwadang-ri was very diverse, with 44 taxa identified, representing three phyla: brown algae (phylum Ochrophyta), red algae (phylum Rhodophyta), and green algae (phylum Chlorophyta). Red algae exhibited the greatest diversity (26 taxa), followed by brown algae with 11 taxa, and green algae (represented by 7 taxa). The near seaside stations were characterized by the relatively higher individual density or abundance across areas than the stations in the open sea. Five species (Ulva pertusa, Sargassum fulvellum, Sargassum horneri, Sargassum thunbergii, and Undaria pinnatifida) dominated in terms of relative abundance. For the entire community, the values of temporal heterogeneity were low at the open sea stations and higher at the others. Overall, the results indicate that spatial heterogeneity in species composition among the replicates was not high. However, distribution of abundance of seaweeds showed statistically significant north-south differences at the studied sampling sites.
Key words: seaweeds, size-frequency distribution, spatial patterns
