옥정현,이인규 한국조류학회I 2005 ALGAE Vol.20 No.2
Eight species of Sargassum subgenus Bactrophycus section Teretia were collected from the coasts of Korea: S.confusum C. Agardh, S. pallidum (Turner) C. Agardh, S. muticum (Yendo) Fensholt, S. thunbergii (Mertens ex Roth) Kuntze, S. fulvellum (Turner) C. Agardh, S. hemiphyllum (Turner) C. Agardh, S. nipponicum Yendo, and S. miyabei Yendo. These species were investigated on morphological variations and geographical distribution in Korea. The valuable taxonomic characters between similar species of this section were discussed with special reference to thickness of leaves, types of holdfasts, shape of leaves and vesicle, and length of rhizoids.

New Records of Marine Algae from Korea II
옥정현,금연심,황미숙,오윤식 한국조류학회I 2005 ALGAE Vol.20 No.3
Two species of marine algae, Fauchea spinulosa Okamura et Segawa (Rhodymeniaceae, Rhodophyceae) and Stictyosiphon soriferus (Reinke) Rosenvinge (Chodariaceae, Phaeophyceae) were newly collected from the southern coast and Cheju Island of Korea. Fauchea spinulosa was collected from subtidal zone in the insular region of the southern coast. Plants were erect from the discoidal holdfast with short stipe, pinkish to deep red, cartilageneous, dichotomously and flabellately branched, and 10-15 cm high, 5-15 mm broad. Tetrasporangia are cruciately divided and nemathecia occurred on a side of the branches. Cystocarps were mostly coronate in marginal area and spermatangia were scattered on both sides of branches. Stictyosiphon soriferus commonly occurs on muddy and sandy intertidal flat of Namhaedo located on the southern coast. Plants are epilithic, light brown, terete, 3-5 cm high, and branched heavily in irregular or alternate manner, arising from a small holdfast with rhizoidal clumps. Plurilocular sporangia were scattered in patches and slightly swollen above the cortex of the whole filament. Unilocular sporangia were not found.

Eight species of Sargassum subgenus Bactrophycus section Halochloa and Repentia were collected from the coasts of Korea: Sargassum coreanum J. Agardh, Sargassum sagamianum Yendo, Sargassum micracanthum (Kutzing) Endlicher, Sargassum macrocarpum C. Agardh, Sargassum autumnale Yoshida, Sargassum siliquastrum (Mertens ex Turner) C. Agardh, Sargassum serratifolium (C. Agardh) C. Agardh, Sargassum yezoense (Yamada) Yoshida et Konno. These species were investigated on morphological variations and geographical distributions in Korea. The valuable taxonomic characters between similar species of these section were discussed with special reference to types of holdfasts, shape of main branch, leaves and vesicles.
Apoglossum minimum and A. gregarium (Delesseriaceae, Rhodophyta),Two New Records from Korea
박미라,옥정현,이인규,Park, Mi-Ra,Oak, Jung-Hyun,Lee, In-Kyu The Korean Society of Phycology 2006 ALGAE Vol.21 No.4
Two species of Apoglossum is newly recorded in Korea collected from subtidal habitats of Jeju Island. Apoglossum minimum Yamada has previously been known only from the coast of Japan. It is characterized by having corticated midrib but lacking microscopic veins. Apoglossum gregarium (Dawson) Wynne is reported for the first time from the north western coast of Pacific Ocean. It has been distinguished by its ecorticate midrib from the former species. Their morphological characteristics in detail and taxonomic issues are discussed.

Porphyra yezoensis is known to act as a biofilter against nutrient-rich effluent in seaweed-based integrated aquaculture systems. However, few studies have examined its physiological status under such conditions. In this study, we estimated the photosynthetic activity of P. yezoensis by chlorophyll fluorescence of PSII (∆F/F'm and relative ETRmax) using the Diving-PAM fluorometer (Walz, Germany). In addition, bioremediation capacity, tissue nutrients, and C:N ratio of P. yezoensis were investigated. The ammonium concentration in seawater of seaweed tank 4 decreased from 72.1±2.2 to 33.8±0.4 µM after 24 hours. This indicates the potential role of P. yezoensis in removing around 43% of ammonium from the effluents. Tissue carbon contents in P. yezoensis were constant during the experimental period, while nitrogen contents had increased slightly by 24 hours. In comparison with the initial values, the ∆F/F'm and rETRmax of P. yezoensis had increased by about 20 and 40%, respectively, after 24 hours. This indicates that P. yezoensis condition improved or remained constant. These results suggest that chlorophyll fluorescence is a powerful tool in evaluating the physiological status of seaweeds in a seaweed-based integrated aquaculture system.
Effect of light and sediment grain size on the vertical migration of benthic diatoms
Guo Ying Du,옥정현,Hongbo Li,정익교 한국조류학회I 2010 ALGAE Vol.25 No.3
Using chlorophyll fluorescence, the vertical migration of benthic diatoms responding to light intensity and affected by sediment grain size was studied. Minimal fluorescence (Fo) of surface sediment was measured by imaging pulse amplitude modulated (Imaging-PAM) fluorometer, and used to monitor diatom biomass variation in surface sediments. The test diatoms, Amphora coffeaeformis (C. Agardh) Kützing and Cylindrotheca closterium (Ehrenberg) Reimann & Lewin,migrated to the sediment surface under irradiance from 50 to 500 μmol photons m-2 s-1. However, the diatoms exhibited no evident increase of surface biomass under dark conditions, and even showed slightly decrease of surface biomass under irradiances over 1,000 μmol photons m-2 s-1. The light intensity inducing the maximum surface migration of A. coffeaeformis was 100 μmol photons m-2 s-1, while the light intensity producing the same effect for C. closterium was 250μmol photons m-2 s-1. C. closterium showed higher motility than A. coffeaeformis. Faster diatom surfacing was observed in larger grain size sediments (125-335 μm) than smaller ones (63-125 μm). This study confirmed the significant influence of light as a main triggering factor behind migration, indicated the distinct effect of different sediment grain size,and highlighted the species-specific migratory ability.
