Marine invertebrates are abundant in Korean waters. However, biological researches on marine invertebrates are limited to the faunal studies in most of the taxa. About 2 800 species of the marine invertebrates (excluding Protozoa) have been reported from Korea. In crustacean decapods, one of the well known group in Korea, 83 species of shrimps (including 16 freshwater species, and infraorders Astacidea and Palinura), 187 of crabs, and 59 of anomurans (including infraorder Thalassinidea) are known. Looking at decapod biodiversity, southern form and temperate zone form are abundant and the highest species diversity is observed in the Cheju Island waters. 29 species of shrimp, 4 of anomuran, and 24 of crab are economically important and 10 species of shrimp, 19 of anomuran, and 55 of crab are considered as rare species. Molecular phylogenetic studies based on the nucleotide sequences of macromolecules are limited to some animal groups such as anthozoans, crustacean decapods, copepods, molluscans, branchiobdellidans. With the current knowledge about the marine invertebrate fauna as well as the crustacean decapods in Korea, it is difficult to discuss the various aspects of biodiversity. Therefore, the continuous collections, inventory, faunal and systematic studies including molecular approaches one very marine invertebrates are urgently in need.

The effect of 100 μM cobalt (Co) on plant growth and on biochemical parameters indicative of oxidative stress was investigated in a hydroponic experiment. The responses of antioxidant enzymes and compounds of the ascorbate–glutathione (AsA–GSH) cycle were also assessed on the hyperaccumulating plant, Indian mustard (Brasssica juncea L.). The effect of excess Co was associated with a significant increase in the levels of proline, carbonylated protein, malondialdehyde, superoxide anion (O2 ‾), and hydrogen peroxide (H2O2), and resulted in the accumulation of Co. Co toxicity was associated with an increase in the volume of palisade and spongy cells, and a reduction in the number of chloroplasts per cell. Co-induced cell death was characterized by DNA fragmentation and a 36 kDa DNase activity. Despite decreased catalase activity, peroxidase, superoxide dismutase, and AsA–GSH cyclerelated enzymes including monodehydroascorbate reductase, dehydroascorbate reductase, and glutathione reductase exhibited remarkable induction under Co stress. Furthermore, the contents of reduced and oxidized forms of ascorbate and glutathione were significantly increased with Co supplementation. Co treatment led to the activation of 44 and 46 kDa mitogen-activated protein kinase (MAPK) and indicated the role of the MAPK cascade in transducing Co-mediated signals. The present results suggest that excess Co reduces seedling growth by inducing oxidative stress related to lipid peroxidation and overproduction of O2 ‾ and H2O2. The stimulated activities of antioxidative enzymes and induction of MAPKs did not reverse the oxidative stress caused by Co-induced reactive oxygen species generation in Indian mustard seedlings.
