Ecological Characteristics of Marine Algal Communities at the Discharge Canals of Three Nuclear Power Plants on the East Coast of Korea

摘要: The species composition and biomass of marine algae at the discharge canals three (Gori, Wolseong Uljin) nuclear power plants on east coast Korea were investigated seasonally from February 1992 to October 2000. As a result, 103-107 found during past nine years. In general, algal communities established less diverse than those intake control sites. 43 (6 blue-green, 9 green, 10 brown 18 red algae) occurred more 1/6 frequency thus can be categorized as warm tolerant species. Among these, two green (Urospora penicilliformis, Cladophora albida), four (Sphacelaria divaricata, S. rigidula, Sargassum coreanum, fulvellum) (Stylonema alsidii, Bangia atropurpurea, Hypnea charoides, Chondria crassicaulis) are recorded for first time in this study. Enteromorpha compressa, Padina arborescens, Amphiroa zonata Ahnfeltiopsis flabelliformis common 50% all investigated. Dominant arborescens zonata. Results showed that, whole, appeared predominant group Korea. However, proportion dominant each plant varied over year
