Productivity of seagrasses can be controlled by physiological processes, as well as various biotic and abiotic factors that influence plant metabolism. Light, temperature, and inorganic nutrients affect biochemical processes of organisms, and are considered as major factors controlling seagrass growth. Minimum light requirements for seagrass growth vary(More)
Existing FPGAs have fairly simple and inefficient configuration mechanisms due to the relative infrequency of re-configuration. However a large class of dynamically config-urable architectures for DSP and communications can benefit from special-purpose configuration mechanisms which allow significant savings in configuration speed, power and memory. Light(More)
Porphyra spp. (currently Porphyra and Pyropia) are major sources of seafood globally. In this study, we investigated the effects of ammonium concentration, water temperature, and thallus stocking density on N-ammonium uptake rate (NUR), tissue nutrients content, N–NH4 + filtration efficiency (NUE: nitrogen uptake efficiency %) of Pyropia yezoensis at a(More)
We tested the hypothesis that the community structure and biochemical composition of macroalgae reflect the degree of nutrient concentrations in the water column. Benthic community structure and tissue nitrogen (N) content of macroalgae on intertidal rocky shores at three sites were investigated in relation to sewage effluents on Mireuk Island, Tongyeong(More)
Photoacclimatory responses of the seagrass Zostera marina in the intertidal and subtidal zones were investigated by measuring chlorophyll a fluorescence parameters, photosynthetic pigments, leaf δ13C values, and shoot morphology in two bay systems. Intertidal plants had higher carotenoid concentrations than subtidal plants to avoid photodamage under excess(More)
Caffeic acid phenethyl ester (CAPE) exhibits various pharmaceutical properties, including anti-bacterial, anti-inflammatory, anti-viral, anti-cancer, and anti-oxidative activity. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been a promising anti-cancer agent that preferentially induces cancer cell apoptosis with negligible(More)
We identified single nucleotide polymorphism (SNP) markers in the laccase gene to establish a line-diagnostic system for shiitake mushrooms. A total of 89 fungal isolates representing four lines, including Korean registered, Korean wild type, Chinese, and Japanese lines, were analyzed. The results suggest that SNP markers in the laccase gene can be useful(More)
The effects of intensity and timing of disturbances on recovery of marine benthic organisms were investigated on a rocky intertidal shore in Gwangyang Bay, Korea. We hypothesized that the recovery pattern of the benthic community structure would be affected by disturbance intensity and season. Twenty-eight permanent plots were set up, with disturbance(More)
