Differences in Subtidal Macrobenthic Community Structures and Influencing Factors Between Jindo and Jeju Islands in South Korea.

Although islands in South Korea have been significantly impacted by human activities, marine ecological studies focusing on island coasts have been limited. Due to their distinct characteristics, macrobenthos is extensively utilized to assess the impact of anthropogenic influences on the marine environment. In August 2010, August 2011, and September 2012, samples of macrobenthic communities, bottom water, and sediment were collected from the subtidal zones around southern Jindo and northern Jeju islands in South Korea.

Assessment of Benthic Ecological Quality Status in the Subtidal Zone of Northern Jeju Island, South Korea, During Summer Based on Macrobenthos.

Background: Jeju Island is a world-renowned tourist destination. However, with the increasing intensity of anthropogenic activities, the coastal marine environment of Jeju Island has been negatively affected.

Methods And Results: Our study used five benthic indices to assess the ecological quality of the subtidal zone in northern Jeju Island.

Complete mitochondrial genome of the marine mysid (Mysida, Mysidae).

The complete mitochondrial genome was sequenced from the marine mysid . The sequenced total genome size was 19,135 bp. The mitochondrial genome of contained 13 protein-coding genes (PCGs), two rRNAs, and 22 tRNAs.

Variation of Spirulina maxima biomass production in different depths of urea-used culture medium.

Fewer studies have assessed the outdoor cultivation of Spirulina maxima compared with S. platensis, although the protein content of S. maxima is higher than S.

Effects of sediment disturbance caused by bridge construction on macrobenthic communities in Asan Bay, Korea.

Changes in soft-bottom macrobenthic communities and the effects of anthropogenic disturbances were studied. We compared biological and environmental samples during and after bridge construction (DBC and ABC). Significant differences were detected in sediment composition at three stations, although hydrographic conditions were similar for DBC and ABC samples.

Reproduction and growth of the freshwater prawn, Palaemon paucidens (Decapoda: Palaemonidae) in a lake of Korea.

This study analyzed the reproduction and growth of freshwater prawn, Palaemon paucidens De Haan 1844 from Suk-dang lake(Korea). The analysis of the sex ratio showed a higher proportion of males than that of females. The average size of the eggs was 6.

Effects of copper (I) oxide on growth and biochemical compositions of two marine microalgae.

In copper based antifouling (AF) paints Cu (I) oxide was largely used as booster biocide. In this study effect of Cu (I) oxide on two marine microalgae, Tetraselmis suecica and Dunaliella tertiolecta was demonstrated. EC50 (96 hr) concentrations estimated for T.

Purification and characterization of an anionic isoperoxidase from scented-geranium callus.

Secretory anionic isoperoxidase (EC 1.11.1.
