Some methods of fuzzy sels are applied to the analysis of water masses in the north area of the South China Sea. In distinguishing water masses with the fuzzy clustering method, the authors propose a fuzzy similar relation based on Euclidean distance, and {2.ggest a method for determining the number of water masses by the F-test, and further adjust rationally the boundaries of water masses and the membership relation of samples by the elastic classification method. Eight water masses are distinguished in the area, i.e., Nearshore Diluted Water F, Nearshore Mixed Water M, Warm {2.rface Water WS, {2.rface Water S, {2.rface-{2.b{2.rface Mixed Water {2., {2.b{2.rface Water U, {2.b{2.rface-Intermediate Mixed Water UI and Intermediate Water I.

The phylogenetic relationships of 13 snapper species from the South China Sea have been established using the combined DNA sequences of three full-length mitochondrial genes (COI, COII and CYTB) and two partial nuclear genes (RAG1, RAG2.. The 13 species (genus Lutjanus) were selected after DNA barcoding 72.individuals, representing 2. species. Our study suggests that although DNA barcoding aims to develop species identification systems, it may also be useful in the construction of phylogenies by aiding the selection of taxa. Combined mitochondrial and nuclear gene data has an advantage over an individual dataset because of its higher resolving power.

Studies were undertaken to investigate the activity response of the antioxidant enzymes superoxide dismutase (SOD) , glutathione peroxidase (GPx), glutathione reductase (GR) and mercury reductase (MR) of Antarctic bacterium Pseudoalteromonas sp. NJ62.following exposure (when exposed) to HgCl2. SOD activity of Pseudoalteromonas sp. NJ - 62.which was identified as Mn - SOD increased when incubated with 5 μM Hg2.+. And a significant increase in the activities of GPx, GR and MR was observed after exposure to Hg2.. These antioxidant (antioxidant enzymes)responses may be used as biomarkers of oxidative stress induced by mercury pollutants in Antarctic ecosystems.
