ABSTRACT |
We observed the algal species compositions and the marine algal flora in the Islands of Ullungdo and Dokdo in May, June, August and November, 1999. The total number of marine algal species was 56 species composed of the brown algae of 22 species, the red algae of 6 species. Among them, 53 species were recognized in Ullungdo and 24 species in Dokdo. The sudden decrease of the algal species was distinguished as comparing with the results of the whiting event which dispersed in the littoral zone. The dominant algal species of Ullungdo and Dokdo were Eisenia bicyclis and Sargassum sp. of brown algae, Pachymeniopsis lanceolata, Chondria crassicaulis, Chondrus ocellatus, Corallina officinalis and C. pilulifera of red algae and Cladophora opaca, Codium fragile, Enteromorpha compressa and E. linza of green algae.
