ABSTRACT

Benthic marine algae of Chongsando Island on the South Sea of Korea have been investigated, considering the floristic composition and community structure in intertidal to subtidal zones at three sites by a belt transect method in January to August. 1989. As a result, a total of 140 species were identified: 4 blue-green, 16green, 34 brown, and 86 red algae/ Among them,116, 97 and 29 species of marine algae occurred at Tangri, Chinsanri and Dongchonri, respectively. The dominant species in frequency and coverage were represented as Hizikia fusiformis, Gloiopeltis furcata and Corallina pilulifera at Tangri, and Sargassum horneri, Corallina officinalis and Gloiopeltis furcata at Chinsanri. A vertical zonation of the algal communities in coverage was analysed as Gloiopeltis furcata-Ulva pertusa (in summer), Monostroma grevillei (in winter)-Corallina pilulifera, Hizikia fusiformis-Sargassum micracanthum, Ecklonia cava at Tangri, and Gloiopeltis furcata-Ulva pertusa (in summer), Corallina officinalis, Hizikia fusiformis, Sargassum thunbergii-Sargassum horneri, Corallina officinalis at Chinsanri.
