The summer algal flora and community of 15 uninhabited islands in Dochodo, southwestern coast of Korea, were investigated from 9 June to 16 September 2007. A total 53 species (10 green, 14 brown and 29 red algae) of marine algae were identified. Among 15 uninhabited islands, the number of species observed was the highest as 33 species at Jeongdo and Gyeongchido the least as 24 species at Hugdo and Mido. The dominant species were Enteromorpha compressa, Ishige okamurae, Gloiopeltis furcata, Ulva pertusa and Sargassum thunbergii. The algal zonation of intertidal zone was figured out by Gloiopeltis furcata, Caulacanthus okamurae – Ulva pertusa, Sargassum thungergii – Gelidium amansii, Sargassum horneri from upper to lower zone. The flora investigated could be classified into six functional groups such as coarsely branched form (39.6%), filamentous form (25.8%), sheet form (14.1%), thick leathery form (9.9%), jointed calcarious form (5.6%) and crustose form algae (4.9%).

Marine algal flora and community structure were investigated seasonally at three sites in Ilkwang Bay on the southern east coast of Korea from May 2007 to February 2008. Total 103 species including 10 of green algae, 17 of brown algae, 76 of red algae were collected and identified. Among these species, 21 species were found throughout the year. Ulva pertusa, Enteromorpha linza, Grateloupia lanceolata, Chondracanthus intermedia and Caulacanthus ustulatus were distributed dominantly in upper intertidal zone. By contrast, crustose coralline algae, Grateloupia spp., Chondracanthus tenellus, Prionitis cornea and Sargassum spp. occurred predominantly in middle intertidal zone. Grateloupia spp., Sargassum spp., Ecklonia cava and Ulva pertusa were dominant in lower intertidal zone. Annual mean biomass in wet weight was 478.3 g m$^{-2}$. Maximum biomass was recorded in site 1 (731.8 g m$^{-2}$), and minimum was recorded in site 3 (78.5 g m$^{-2}$). The R/P, C/P and (R + C)/P value reflecting flora characteristics were 4.47, 0.59 and 5.06, respectively. Two groups produced by cluster analysis, one including sites 1, 2 and the other including site 3, showed meaningful difference in similarity, each other. Site 3 showed the limited species composition due to inflow of fresh water and absence of solid substratum. However, there was no significant difference between site 1 and site 2. In conclusion, the number of marine algae species and biomass in Ilkwang Bay were markedly reduced comparing with the previous studies. These suggest that a solution for reconstruction of the poor marine algal vegetation is considerably demanded.

Beakryoung-do is located in the north along the western coast of South Korea. Owing to its geographical limitations, not many studies have been conducted on marine algae in this region. This study aims to investigate the marine algal flora and the community structure in the intertidal and subtidal zones of Nampo-ri, Beakryoung-myeon, Ongin-gun, Incheon regions of South Korea. The study was conducted from August 2015 to June 2016 during all seasons. A total of 95 algal species, including 7 green algae, 12 brown algae, and 76 red algae were collected and identified; 52 algal species were found in the intertidal zone and 83 in the subtidal zone. The vertical distribution of algae from upper to lower intertidal zone was Neorhodomela aculeata - Caulacanthus okamurae, Gelidiophycus freshwateri - Neorhodomela aculeata, Caulacanthus okamurae - Sargassum thunbergii, Caulacanthus okamurae. Findings indicated that Sargassum thunbergii and Neorhodomela aculeata were the biomass-dominant species in the intertidal zone and Corallina officinalis and Undaria pinnatifida were biomass-dominant in the subtidal zone. Average values of marine algae biomass in the intertidal and subtidal zones were 252.6 g wet weight m^-2 and 291.9 g wet weight m^-2, respectively. Further, 38 new species were found in Beakryoung-do, with 25 of them specifically found in the subtidal zone. More studies on marine algal flora in the subtidal zone are needed to understand the changes in marine flora along the western coast.

A great portion of the marginal zone in Lake Gocheonam was covered with reed plants. Algae attached to the reed stems were exclusively composed of diatoms. Sixty-six species of diatoms were encountered in a floral survey. The important species were Nitzschia liebetruthii Rabh., Nitzschia acicularis (Ku¨tz.) W. Sm., Navicula gregaria Donk., Cocconeis placentula var. lineata (Ehr.) V.H. etc. Among the diatom flora, six species - Navicula nivalis Ehr., Navicula recens Lange-B., Nitzschia angustatula Lange-B., Nitzschia compressa (Bail.) Boyer, Nitzschia lanceola var. minutula Grin. and Surirella crumena Bre´b. - were recorded in Korea for the first times. Life forms of the reed-attached diatoms were simply prostrate. The biomass of epiphytic algae ranged from 0.05㎍ chl-$\alpha$ cm$^{-2}$ to 2.32$\mu$g chl-$\alpha$ cm$^{-2}$. The algal biomass of dead stems was higher than that of the living stems, and their flora were rich. The algal biomass reached a maximum in the spring after the death of the reed plants. The reed plants exhibited rich diatom flora and significantly high algal biomass on their stems to have taxonomical and ecological importance in the freshwater.

The objective of this study was to clarify marine algal flora and community structure of 16 uninhabited islands in Sinangun area, south western coast of Korea. As a result, a total of 63 species - 11 greens, 16 browns and 36 reds - was identified. The functional groups of marine algal species were filamentous 14.3%, foliose 20.5%, corticated 45.3%, leathery 13.7%, and articulated calcareous algae 6.2%. The (R+C)/P value was calculated as 2.9 showed temperate flora. The result of DCA showed that 16 uninhabitated islands tend to be distributed eastern and western parts. The dominant species was Ulva pertusa, while the subdominats were Gelidium divaricatum, Myelophycus simplex. The vertical distribution pattern of intertidal marine algae represented three distinct zones; Gloiopeltis furcata, Myelophycus simplex, Gelidium divaricatum - Ulva pertusa, Enteromorpha spp., Ishige okamurae - Ulva pertusa, Sargassum thunbergii, Symphyocladia latiuscula.

Marine algal flora and community structure were investigated seasonally at three sites in Gijang on the south-east coast of Korea from February 2006 to January 2007. A Total of 74 species were collected and identified, including 8 green algae, 16 brown algae, and 50 red algae. Of these, 15 species were found throughout the survey period. Mean biomass was 823.2-1,615.4 g wet weight $m^{-2}$ in winter, 689.1-3,196.8 g wet weight $m^{-2}$ in spring, 574.5-1,219.9 g wet weight $m^{-2}$ in summer, and 747.6-1,616.2 g wet weight $m^{-2}$ in autumn. The flora could be classified into six functional groups: coarsely branched form (37.8%), thick leather form (18.9%), sheet form (13.5%), filamentous form (12.2%), jointed calcareous form (10.8%) and crustose form (6.8%). The R/P, C/P and (R+C)/P values reflecting the flora characteristics were 3.13, 0.50 and 3.63, respectively. The number of marine algae species and the biomass in Gijang area were markedly reduced when compared with previous studies. This result suggests possible future changes in the algal vegetation, considering the physical and chemical pollution loadings in the coastal marine environment of this area.
