Marine Benthic Algal Community at Padori, West Coast of Korea
Jae Wan Lee, Byoung Geon Oh, Hae-Bok Lee
An intertidal marine benthic algal vegetation at Padori, west coast of Korea was investigated to clarify the pattern of community structure from December, 1997 to September, 1998. As a result, a total of 50 algal species-6 greens, 15 browns and 29 reds-was identified. In vertical distribution of intertidal marine algae, Gloiopeltis furcata was at the upper, Sargassum thunbergii and Corallina pilulifera at the middle, and S. thunbergii and Hizikia fusiformis at the lower zones, respectively. The dominant species was Corallina pilulifera, and the subdominants were S. thunbergii, Chondrus ocellatus, Ulva pertusa and Hizikia fusiformis. This biomass of the algal community on an average was 123.2g·m supper(2) in dry mater. Comparing the result of this study to those of five and ten years ago, the number of species and the biomass markedly decreased. In the analysis of the functional group form of marine benthic algae, the filamentous and the foliose algae relatively decreased, whereas the leathery macrophytes increased in species composition. The composition of seaweed flora was changed from the mixed to the subpolar-temperate flora.
Key words: algal flora, biomass, dominant species, Padori, west coast
