| Abstract: | For the first time, the structure of the meiobenthos community and marine nematodes in particular was investigated in the
different intertidal zones of Jeju Island (South Sea of Korea). A relationship was found between the density of meiobenthic
communities and the type of the bottom sediment. In addition, in the silty sediments, nematodes were dominant, while in the
sandy sediments harpacticoids and ostracods were dominant groups. Sixty eight species belonging to 60 genera and 19 families
of nematodes were found in the whole area. Four different nematode taxocenosis were distinguished using a cluster analysis.
Dominant feeding groups were omnivores (2B) and epistratum-feeders (2A). The highest number of non-selective deposit-feeders
(1B) was detected in the lagoon with the bottom silty sediments. |
