Composition and Distribution of Meiobenthos in Amursky Bay (Peter the Great Bay, the East Sea)
Olga N. Pavlyuk,Julia A. Trebukhova 한국해양과학기술원 2005 Ocean science journal Vol.40 No.3
and quantitative composition of meiobenthos was studied in Amursky Bay (Peter the Great Bay, the East Sea). Ten taxonomic groups were found, where nematodes were dominant. Density of meiobenthos in ground sediments of the Bay were not uniform, and the average density was measured at 126.462.3 ind. m-2. 56 species of nematodes were detected, and dominant species were Sabatieria palmaris, Paracanthonchus macrodon, Sphaerolaimus limosus, S. gracilis and Oncholaimium ramosum. Five taxocenes of nematodes were allocated based on the results of cluster analysis and species domination according to density. Low diversity in species composition of nematodes was noted in the northwestern part of the Bay, which is a zone of desalination, and in the eastern part, which is exposed to household drains.

Qualitative and quantitative composition of meiobenthos was studied in Amursky Bay (Peter the Great Bay, the East Sea). Ten taxonomic groups were found, where nematodes were dominant. Density of meiobenthos in ground sediments of the Bay were not uniform, and the average density was measured at $126.4{\pm}62.3ind.mo^{-2}$. 56 species of nematodes were detected, and dominant species were Sabatieria palmaris, Paracanthonchus macrodon, Sphaerolaimus limosus, S. gracilis and Oncholaimium ramosum.

Meiobenthos in Nha Trang Bay of the South China Sea (Vietnam)
Pavlyuk, Olga N.,Trebukhova, Julia A. The Korean Society of Oceanography 2006 Ocean science journal Vol.41 No.3
The distribution of the taxonomical composition and the density of meiobenthos depending on the sediment type has been studied in bottom sediments of Nha Trang Bay. The maximal population density and the taxonomical diversity were observed in the silted coarse and heterogeneous sand ($1031.4{\pm}419.7\;ind.\;10\;cm^{-2}$), whereas the minimal level of density and diversity ($588.1{\pm}152.5\;ind.\;10cm^{-2}$) was in the coarse and heterogeneous sand with shell debris and corals. The correlation between the median diameter of sediment particles and population density of meiobenthos has been revealed (r=0.82, p<0.05). In bottom sediments of Nha Trang Bay, twenty six taxonomic groups of meiobenthos were observed. Nematodes dominated in all sediment types. Representatives of four orders, twenty eight families and ninety seven genera of marine nematodes were identified. The vertical distribution of meiobenthos in different sediment types was considered. A sediment column (10 cm height) was sectioned by five 2 cm portions. In the last layer (8-10 cm) the most number of meiobenthic groups was found in sandy sediments. In the lower layers of silt sediments, only nematodes were found.
