Benthic Marine Algal Flora and Community Structure of Yongho-dong Area in Pusan, Korea

摘要: Benthic marine algal flora and community structure of Yongho-dong area in Pusan, Korea were investigated seasonally intertidal subtidal zones by a quadrat method along 5 transect lines from July 1996 to April 1997. In this area, total 99 species including 3 blue-green, 13 green, 26 brown 57 red algae was found. Among them, 33 taxa, together with dominant Ulva pertusa Corallina pilulifera, occurred throughout the year. Enteromorpha spp. vertically distributed upper middle zone, while Simphyocladia latiuscula, Chondria crassicaulis, pilulifera Sargassum sup. lower zones. Biomass per unit exhibited wide range variation, 1,241 g/(spring) 1,648 g/(summer) fresh weight. Maximum minimum diversity recorded spring autumn, respectively. Results UPGAM cluster analysis suggest that examined sites can be divided into two groups, exposed open sea (transects 1, 2, 3) comparatively sheltered 4, 5) faced Pusan Harbor. The former group is represented large algae, Hizikia, Lomentaria are mainly found latter group. A calcareous alga, dominantly both groups conclusion, number remarkably reduced as compared previous data. This result may probably more change vegetation future, considering physical chemical pollutions loaded coastal environment area.
