  • Some asteroids were collected at a depth of 30 m in Chejudo Island. Of which two species were identified as Luidia maculata Muller et Troschel, 1842 and Linckia laevigata Linne, 1758. These species are turned out to be new to the Korean fauna and redescribed on the morphological characteristics with illustrations. Eighteen species of asteroids are reported to be distributed in the Chejudo Island of Korea.

  • Three xanthoid crabs Novactaea pulchella (A. Milne Edwards, 1865), Calvactaea tuminda Ward, 1933, and Pilumnopeus granulatus Balss, 1933, from Chejudo Island are recorded as new to the Korean fauna. Up to date the Korean crabs of the superfamily Xanthoidea consist of 29 species belonging to 3 families.

  • Thirteen cumacean species in four families were identified from the southern coast and Chejudo Island in Korea. Three of them, Campylaspis pumila Gamo, Cumella alveata Gamo, and Cumella glaberata Gamo, are recorded newly to Korean fauna. Among them, female of C. alveata is described for the first time in the would.

  • This study was made on the relationships among production structures, biomass and Soil proper-ties of grassland types in Chejudo. The results of this investigation were obtained as foolows. The annual productions of the grasslands of Zoysio, Imperata, Themede, Miscanthus and Pteridium types were 40.36~144.00, 168.28~272.44, 58.24~138.44, 156.12 ~714. 12 and 157. 18~398.40g /m$^2$, respectively. The production structures of those grassland types were different from one another. The water contents, organic matter, total nitrogen and available phosphorus were different levels between grasslands had a simple correlation at 5% level and the organic matter contents were a higher significant at the partial correlation. Key words: Production Structure, Biomass, Soil properity, Chejudo.

  • A number of hydrographic studies and some recent current measurements around Chejudo Island suggest an existence of a clockwise residual flow in the west and north coasts of the island all the year round. On the eastern side of the island the Tsushinma Current flows northward and northeastward. The contribution of tide-induced residual currents to the observed residual. flow around the island was examined here through numerical solution of the two-dimensional nonlinear shallow-water equations. The calculated tide-induced residual currents show a clockwise circulation around the island. Significant residuals of 2-4cms$\^$-1/are confined over sloping bottom topography around t he island and the far-field residuals are negligibly small. The inclusion of a permanent current into the model was also attempted in order to see the effects of the Tsushima Current system on the residual circulation around the is land. It was found that combined effects of tide-induced residuals and the permanent current field associatedwith the Tsushima Current explain qualitatively not only the observed clock wise residuals in the west and north coasts but also the northward flow on the eastern side of the island.

  • To clarify the spider fauna of Geojedo Island, a field survery was conducted in August, 1997. As a result, 92 species belonging to 56 genera of 20 families were collected. Identified spider are composed of 6.60% Palaearctic, 7.70% Holarctic, 2.20% Oriental, 3.30% cosmopolitan species. Spiders of Theridiidae, Araneidae and Salticidae were dominant, 82(90.1%) and 75 species(82.4%) of spiders were found in common with Japan, China, respectively. Faunal similarities between Geojedo island and Deogjeong Archipelago, Chejudo Island, Ulleungdo Island, Chindo Island, Paiklyeongdo Island and Kogeumdo Island are discussed.

  • Twently seven speices of marine bryozoans from Namhaedo Island and its adjacent waters were identified. Among them, Hippothoa distans is new to Korean fauna and seven species are added as new to Namhaedo Island fauna. Twenty three species of them have been found also in Chejudo Island waters, which is affected by the Tsushima Current. Ten species have been found in the East Sea which is affected by both the Tsushima Warm Current and the North Korea Cold Current. So it is clear that the Namhaedo Island sea area is influenced by both the Tsushima Warm Current and the North Korea Cold Current.

  • Chejudo, because of its location off the south coast of the Korean peninsula, has a varied marine mollusk fauna. As a preliminary step in an attempt to enumerate and study the mollusks of the island, a field trip was made by the authors to the Songsan Ilchulbang area on february 20, 2001. The purpose of the trip was to survey the mollusk fauna of the shoreline west of Songsan. (omitted)
