Abstract: | 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±62.3 ind. m-2. 56 species of nematodes were detected, and dominant species wereSabatieria palmaris, Paracanthonchus macrodon, Sphaerolaimus limosus, S. gracilis andOncholaimium 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. |
