| ABSTRACT |
|
Seasonal changes of the intertidal marine algal flora and community structure at Sokcho in the east coast of Korea were investigated seasonally from June, 1999 to April, 2000. A total of 67 algal species including 7 greens, 19 browns and 41 reds was identified. The marine algal flora was classified as the temperate flora based on the species composition. The dominant species were Corallina pilulifera in spring and autumn, Sargassum yezoense in summer, and Bangia atropurpurea in winter. The vertical distribution pattern of intertidal marine algae represented three distinct zones; Bangia atropurpurea, Porphyra spp. Gloiopeltis furcata, Chaetomorpha moniligera, Caulacanthus okamurae-Chondria crassicaulis, Dictyota dichotoma, Colpomenia sinuosa, Corallina pilulifera-Corallina pilulifera, Pachymeniopsis elliptica, Sargassum thunbergii, S. yezoense from upper to lower zones. In comparison with the result from the previous survey in 1990, the floristic status in species composition and the dominance were markedly changed.
