독도 해역의 해조류는 2013년 5월과 7월에 14개 정점에서 정성채집 하였으며, 대황의 생태학적 역할을 확인하기 위하여 7월과 11월에 23개체를 채집하여 부착기에 서식하는 해조류와 동물을 동정하였다. 대황의 줄기길이와 무게의 회귀식으로 생물량을 측정하였다. 해조류는 녹조류 18종, 갈조류 35종과 홍조류 75종을 포함하여 총 128종이 관찰되었으며, 성긴분기형이 47.66%로 가장 우점하였고 안정된 환경에 서식하는 ESG I그룹에 속하는 종이 91종(71.09%)이었다. 또한, R/P, C/P, (R+C)/P는 2.14, 0.51과 2.66으로 온대성과 혼합성 해조상을 보였다. 대황의 생물량은 23.74kgm-2이고 밀도는 64 fronds m-2로 확인되었다. 한편, 대황의 부착기에서 해조류 12종과 동물 83종(환형 15종, 연체25종, 절지 34종, 극피 3종, 기타 6종)의 1,248개체가 동정되어 생태학적으로 매우 중요한 핵심종으로 확인되었으며, 넓은마디육질꼬리옆새우붙이가 538개체(43.11%)로 가장 우점하였다. 본 연구 결과 독도의 해조류 출현종수는 이전연구에 비해 증가하였고 성긴분기형과 ESG I 해조류가 우점하는 것으로 나타나 현재까지 독도 연안의 환경은 매우 안정된 상태라고 판단된다. Seaweeds were identified after qualitative sampling at 14 stations of Dokdo coasts from May to July 2013 and seaweeds and animals inhabiting 23 Eisenia bicyclis plants were examined to evaluate its ecological role. Biomass was calculated by using regression between stipe length and weight of E. bicyclis. A total of 128 species were identified, including 18 green, 35 brown, and 75 red algae. Coarsely branched form was dominant functional group occupying 47.66% and 91 species (71.09%) were in ESG I group, growing in stable environmental coast. Also, R/P, C/P, and (R+C)/P were 2.14, 0.51, and 2.66, respectively showing temperate and mixed flora. Biomass and density of E.bicyclis were 23.74kg m-2 and 64 fronds m-2. Twelve seaweeds and 83 animal species (15 Annelida, 25 Mollusca, 34 Arthropoda, 3 Echinodermata, and 6 others) were observed from 23 holdfasts and Ericthonius pugnax was dominant taxon having 538 (43.11%) of 1,248 animal individuals. These results indicate that E.bicyclis is a keystone species showing very important ecological role. In conclusion, the number of seaweeds increased because of intensive research and dominance of coarsely branched form and ESG I group seaweeds, representing that environmental condition of Dokdo is still intact.

The effects of temperature, light, and salinity on the growth of Costaria costata and Undaria pinnatifida juveniles were examined in laboratory cultures. In a cultivation farm, the monthly yield and density were also investigated between December and April for C. costata and between December and March in 2007 and 2008 for U. pinnatifida. The relative growth rates (RGRs) were greater at 20~60 μmol photons m-2s-1 than at low (0~10 μmol photons m-2s-1) and high (100~180 μmol photons m-2s-l) irradiance levels. The optimal growth conditions for the two species were 17℃, 35 psu, 60 μmol photons m-2s-1, and a daylength of 12 h, indicating that C. costata and U. pinnatifida have very similar growth responses to temperature, light, and salinity. However, the growth responses of the two species to various environmental factors were different; C. costata grew faster than U. pinnatifida but the latter species grew well at low salinity. The monthly yield of C. costata and U. pinnatifida increased steadily over the study period, and it was maximal in March for both species, but the yield of U. pinnatifida was greater than that of C. costata.

한국 태안군 정산포와 황도 갯벌에서 저서미세조류의 종조성과 생물량의 계절적 변화가 바지락 생장과 연관성이 있는지를 파악하기 위하여 2012년 2월부터 11월까지 계절별로 조사되었다. 연구기간 동안 저서미세조류는 총 122종이 관찰되었으며, 정산포에서 85종(계절별 30-45종), 황도에서는 92종(32-57종)이었다. 연평균 엽록소 a 의 농도는 정산포에서 79.75 ㎎/㎡였고 황도에서 151.50 ㎎/㎡였다. 갯벌 퇴적물에서 서식하는 저서미세조류의 연평균 세포수는 정산포에서 13,255 cells/㎠이었고 황도에서 15,943 cells/㎠였다. 정산포에서 Cylindrotheca closterium, Gyrosigma sp.와 Navicula sp.가 우점하였고 황도에서는 Amphora sp.1., C. closterium, Detonula pumila, Navicula sp.와 Merismopedia sp.였다. 또한, 두 연구정점에서 최대의 세포수를 나타낸 종은 Paralia sulcata였다. 정산포 바지락의 소화기관에서는 계절별로 18-31종의 미세조류가 분류되었으며, 황도 바지락 소화기관에서는 19-25종의 미세조류가 동정되었고 P. sulcata는 모든 계절에 바지락 소화기관에서 확인되었다. 바지락의 연평균 비만도는 정산포에서 연평균0.42로 황도의 0.57에 비해 0.15가 낮았다. 결과적으로 바지락의 먹이원인 저서미세조류의 풍도와 엽록소 a 의 농도는 바지락 생장과 밀접한 관련이 있음을 확인하였다. To examine the relationship between microphytobenthos biomass and the condition index of Ruditapes philippinarum (manila clam), field observations were conducted seasonally at the tidal flats of Jeongsanpo and Hwangdo, Taean, Korea from February to November, 2012. A total of 122 species of microphytobenthos were identified over the study period with 85 species (30-45 species in season) at Jeongsanpo and 92 species (32-57 species) at Hwangdo. Chlorophyll a concentrations and cell number of microphytobenthos were 79.75㎎/㎡ and 3,255 cells/㎠ at Jeongsanpo, and 151.50 ㎎/㎡ and 15,943 cells/㎠ at Hwangdo, respectively. The dominant species were slightly different: Cylindrotheca closterium, Fallacia forcipata, Fogedia sp., Gyrosigma sp., and Navicula sp. at Jeongsanpo and C. closterium, Detonula pumila, Diploneis sp., Navicula sp. and Merismopedia sp. at Hwangdo tidal flat. Paralia sulcata was the representative species based on cell number at the two study sites. The number of microphytobenthos identified from the digestive organs of manila clams seasonally varied from 18 to 31 species at Jeongsanpo and dominant genus were Amphora, Navicula, Nitzschia and Paralia sulcata. At Hwangdo, the species number of microphytobenthos found in the digestive organs of manila clams were in the range of between 19 and 25 species in season and the dominant genus were Actinocyclus, Amphora, Coscinodiscus, Diploneis, Gyrosigma, Navicula, and Diploneis. The condition index of manila clams were greater at Hwangdo (0.57) than at Jeongsanpo (0.42). Present results could support that the condition index of manila clams is positively correlated with the species richness and chlorophyll a contents of microphytobenthos.

The intertidal benthic macroalgal floras of 19 uninhabited islands were investigated in the Goheung area, South Sea, Korea, in June 2008. Seaweed community structures on the rocky shores of four (Naemaemuldo, Ceoldo, Araedombaeseom, and Jinjioedo) of the 19 islands were also examined. Eighty macroalgal species were identified, including 13 green, 19 brown, and 48 red algae. The maximum number of species was found at Naemaemuldo, with 35 species, and the minimum was at Aredombaeseom, with 21 species. Seaweed biomass ranged from 21.39-76.22 g dry wt/m2, with a maximum at Naemaemuldo, and minimum at Jinjioedo. Sargassum thunbergii was a representative species, distributed widely in the intertidal zone of the four islands. Subdominant seaweeds were Corallina pilulifera and Ulva pertusa at Naemaemuldo and Jinjioedo, respectively. Also, Ishige okamurae was dominant at Ceoldo and Araedombaeseom. Six functional seaweed forms were found at each study site, except for Araedombaeseom, which had four functional groups. On the rocky shores of the four sites, a coarsely-branched form was the most dominant functional group ranging from 44.44-61.90% in species number and 72.42-91. 09% in biomass. In conclusion, among the four study sites, the shore of Naemaemuldo Island had the best ecological status, with the highest number of species, and greatest biomass (mainly brown and red algae) and functional form diversity of seaweeds. Furthermore, on the rocky shore of Naemaemuldo, coarsely branched- and joint calcareous-form seaweeds, which grow in clean and undisturbed environmental conditions, were the representative functional forms.

암반생물막의 군집구조와 생물량의 시, 공간적인 변화를 확인하기 위하여, 파도에 대한 노출이 다른 고사포와 격포에서 11월부터 2011년 9월까지 격월로 암반조각을 채집하였다. 군집구조는 채집된 암반조각을 칫솔로 긁어 광학현미경 하에서 미세조류의 분류군별 개체수를 계수하여 분석하였고, 생물량은 NDVI, VI, 엽록소 a 농도를 측정하여 확인하였다. 고사포와 격포의 조간대 암반생물막에서 가장 우점하는 분류군은 Aphanotece spp., Lyngbya spp.를 포함하는 남조류였으며, 환경스트레스가 적은 조간대 하부에서는 규조류의 출현율이 높게 나타났다. 암반생물막에서 우점하는 규조류는 Navicula spp., Achnanthes spp.와 Licmophora spp.로 확인되었다. 식생지수와 엽록소 a 농도는 격포에 비해 고사포 생물막에서 높게 나타났다. 식생지수인 NDVI와 VI는 고사포에서 각각 0.49-0.40(평균 0.43), 2.64-3.22(평균 2.90)였으며, 격포의 암반생물막은 NDVI와 VI가 각각 0.32-0.41(평균 0.38), 2.03-2.86(평균 2.48)으로 확인되었다. 엽록소 a의 농도는 고사포에서 12.79-32.87 ㎍/㎠(평균 22.84 ㎍/㎠)였고, 격포에서는 11.14-18.25 ㎍/㎠(평균 15.48 ㎍/㎠)로 식생지수와 마찬가지로 1월(겨울)에 최대, 3월(봄)에 최소인 계절 변화를 보였다. 엽록소 a 농도는 NDVI, VI와 양의 상관관계를 보여 비파괴적인 식생지수 측정방법이 파괴적인 엽록소 a 추출 방법을 대체할 수 있음을 알려준다. 결론적으로 암반생물막은 여름보다 겨울에, 조간대 상부보다 중부와 하부에서, 파도에 보호된 해안보다 노출된 해안에서 높은 값을 보였다. The community structure and abundance of epilithic biofilm were bimonthly examined to know spatial and temporal patterns of biofilm biomass and taxonimical composition at the two study sites, Gosapo and Gyeokpo with different degrees of wave exposure levels from November 2010 to September 2011. Biomass was estimated by using chlorophyll a contents (Chl a), normalized difference vegetation index (NDVI), and vegetation index (VI). Cyanobacteria such as Aphanotece spp. predominated in the proportion of 57.53% at Gosapo and of 61.12% at Gyeokpo and they are abundant in mid shore and in summer at both study sites. The diatoms Navicula spp., Achnanthes spp. and Licmophora spp. were common species and they showed an increasing trend from high to low shore. NDVI, VI, and chl a contents were the greatest at mid shore for Gosapo (0.44, 3.05, 24.56 ㎍/㎠) and at low shore for Gyeokpo (0.41, 2.73, 17.98 ㎍/㎠). NDVI, VI, and chl a content were all maximal in January and minimal in March at the both sites. Average NDVI, VI, and chlorophyll a contents of biofilms were greater at Gosapo (0.43, 2.89, 22.84 ㎍/㎠) than Gyeokpo (0.38, 2.48, 15.48 ㎍/ ㎠).Of three shore levels(high, mid, and low) Chl a contents were positively correlated with NDVI and VI at the two study sites indicating that non-destructive NDVI and VI values can be used in stead of destructive Chl a extraction method. In conclusion, epilithic biofilm was more abundant seasonally in winter, vertically in mid and low intertidal zone, and horizontally at wave exposed shore than in summer, at high and sheltered shore in Korea.

The effects of environmental factors, such as irradiance, daylength, salinity, and desiccation, on the growth of Lithophyllum yessoense and Hildenbrandia rubra sporelings were examined. Sporelings of each species were cultured with 10, 50, 80, 120, 150μmol photon m-2 s-1 for 14 days and their maximum growth occurred under 80 μmol photon m-2 s-1. Germlings of both species survived for 21 days in darkness, and even the L.yessoense germlings grew. In the salinity experiment, sporelings of each species survived for 7 days and died after 14 days under 20 and 25 psu, but the sporelings grew well under 34 psu. Physiological features of each species with respect to the evaluated daylengths (8, 12, 14 and 16 h) were slightly different, and maximal growth occurred at 16 h for L. yessoense and at 14 h for H. rubra sporelings. Mortality of the sporelings increased with the exposure period, but H. rubra was less tolerant to desiccation than L. yessoense. In conclusion, sporelings of the two species showed similar growth responses to various environmental factors with slightly different physiological features with respect to salinity, daylength, and desiccation. However, more ecological and physiological studies on slow-growing crustose algae are required to elucidate the expansion of barren ground around the coastal areas of Korea.

Seasonal variation in marine macroalgal community structure was examined at the intertidal zones of Heuksando and Hongdo,Shinan, Korea, from July 2008 to May 2009. In total, 86 macroalgal species were identified, including 12 green, 19 brown, and 55 red algae; 67 species at Heuksando and 70 species at Hongdo, were observed. Annual seaweed biomass was 252.44 g dry wt /m2 at Heuksando and 217.67 g dry wt/m2 at Hongdo. The dominant seaweed in importance value (IV > 15) differed between the sites: Sargassum thunbergii at Heuksando and Corallina pilulifera at Hongdo. The vertical distribution pattern of seaweeds from the upper to lower intertidal zones at Heuksando was Gloiopeltis spp., Ulva spp. ? S. thunbergii, S. fusiforme, Hildenbrandia rubra ? S. thunbergii, C. pilulifera. On the rocky shore of Hongdo, seaweed zonation was distinct: Porphyra yezoensis, Gloiopeltis spp.,Ulva spp. ? C. pilulifera, S. fusiforme, Myelophycus simplex ? Chondrus ocellatus, C. pilulifera, and Carpopeltis affinis. Annual seaweed coverage, richness index (R), evenness index (J``), and diversity index (H``) values were greater at Hongdo (41.35%, 12.82,0.59, and 2.50 respectively) than at Heuksando (31.54%, 11.93, 0.44, and 1.87 respectively), which may indicate that the seaweed community at Hongdo is more stable relative to the one at Heuksando.
