  • To study the characteristics of rocky intertidal invertebrate fauna on the coastal areas of the East Sea, seven regions including Dokdo, Ulleungdo, Gyeongju, Pohang, Yeongdeok, Uljin, and Gangwondo, the common species ratio (%) and similarity index using Bray-Curtis similarity matrix were calculated. The contributed species for dissimilarity between Dokdo and the other East Sea's coastal areas were selected by using SIMPER. The common species ratio and the cluster analysis showed that Ulleungdo presented the highest similarity. However, Yeongdeok showed the highest similarity in the eastern costal areas, and Gangwondo showed the lowest one. However the cluster analysis revealed the discrimination of the rocky intertidal invertebrate community on Dokdo with others region caused by the particularity of rocky shores exposed to strong wave action and by the particular distribution of rocky intertidal invertebrate fauna in Dokdo.

  • This study was conducted to investigate that affect benthic macroinvertebrates for installed erosion control works at a mountain torrential stream. The survey was carried out six times from April 2007 to October 2008 at two points where erosion control works were installed and at a control point in the upstream with no such works. Variations in the community structure and cluster of benthic macroinvertebrates and ecological water quality were analyzed in the survey. From the six times survey, the identified benthic macroinvertebrates were 6,922 individuals belonged to 27 species, 24 families, 13 orders, 6 classes and 4 phyla. As the average results of three surveyed sites, the dominant species was Gammarus sobaegensis of Amphipoda. The species diversity index(H') showed the highest as 1.47 at Site 2 of the fourth survey and the lowest as 0.24 at Site 2 of the sixth survey. The evenness Index(EI) showed the highest as 0.823 at Site 2 of the fourth survey and the lowest as 0.194 at Site 1 of the fifth survey. The richness index(RI) showed the highest as 2.794 at Site 1 of the first survey and the lowest as 0.291 at Site 2 of the sixth survey. The ecological score of benthic macroinvertebrate community(ESB) and individual of EPT-group were declined during the survey period. The functional feeding group(FFG) showed the highest SH types during the survey period.

  • This study was conducted to search the effects of debris barrier on the benthic macroinvertebrate. Gimcheon was selected as the survey site as it has relatively stable ecosystem with constantly running water. The survey was conducted 6 times before and after the construction of debris barrier from February in 2009 to October in 2010. In the first survey before construction, the identified species were 36 species belonged to 22 families, 9 order, 4 class, and 4 phylum. The figure slightly decreased to 30 species belonged to 18 families, 7 order, 2 class, and 2 phylum in the sixth survey after construction. Before construction, occupation ratio of EPT taxa was showed in the following order: Ephemeroptera (50.0%, 85.0%), Trichoptera (35.3%, 10.0%), and Plecopteran (14.8%, 5.0%). After construction, it was showed in the following order: Trichoptera (50.3%, 68.0%), Ephemeroptera (42.1%, 29.4%), and Plecopteran (7.5%, 2.7%). Ephemeroptera was the highest before construction. Trichoptera increased rapidly after construction. The Diversity, Richness, Evenness, and Dominance indices were all turned low in the second survey right after the construction. However, each index tended to increase with the course of time. In Functional Feeding Groups, GC type was the highest of 60.7% before construction. After construction, SC(53.1%) and FC(35.4%) increased rapidly and they became stabilized since the third survey. The result of this study reveals that debris barrier greatly affects the Aquatic Ecosystem right after its construction, but the system becomes stable and returns to normal with the course of time (about 18 months). Therefore, the study considering various influence factors such as time is required to recover completely through further long-term monitoring.

  • A biological assessment of water quality was carried out in Unmunsan County Park from November 2007 to September 2008. The benthic macroinvertebrates collected from the surveyed sites were composed of 140 species, 106 genera, 61 families, 13 orders, 5 classes and 4 phyla. The dominant species in all the survey areas was Goerodes KUa of Trichoptera. The dominance index(DI) showed the highest as 0.553 at site 2 and the lowest as 0.354 at site 7. The species diversity index(H') showed the highest as 2.18 at site 7 and the lowest as 1.75 at site 2. Ecological score of benthic macroinvertebrate(ESB) showed the highest as 85 at site 4 and site 7 and the lowest as 51 at site 5. As a result, the areas 4 and 7 needed to be designated as the highest protection area, and the area 5 as the protection area. Besides, the water quality, based on the ecological indicators of benthic macroinvertebrate community, turned out to be oligosaprobic in the whole survey areas.

  • The present study is to examine the taxonomy and distribution of holothurians (especially Subclass Dendrochirotacea) as a part of study on marine invertevrate of Korea. The materials were collected at 10 localities in the coastal seas and islands of Korea from April, 1971 to September, 1992. As a result, 16 dendrochirotida species belonging to 13 genera, 4 families were identified, of which 11 species have not been recorded in Korean fauna before.

Three species of annelids, four species of molluscans, and seven species of arthropodes were collected. Annelids were collected from all sampling stations, Neanthes japonica was a dominant species. Biomass reached pick at station 4 and decreased in lower part. Biomass was so unstable that seasonal fluctuation of biomass could observed.

  • As a commemorative joint survey for the 20th anniversary of the Korean Society of Systematic Zoology, molluscan fauna of Jindo Island was investigated from the materials collected from 3 localities of Jindo Island from 29th to 30th of June, 2004. A total of 77 species of 37 families were identified. Among them, 26 species of 18 families are reported for the first time in this area, including Onchidella kurodai (Taki, 1935) that is new to Korean fauna. For O. kurodai, external morphologies were described in detail with illustrations. Combining the present data with those of the previous works revealed that a total of 115 species from 43 families have been recorded in Jindo Island and its adjacent areas thus far. From a biogeographic point of view, some gastropod species (Bittium craticulatum, Mocroschisma dilatatum, Cantharidus japonicus, C. callichroa, Homalopoma sangarense, and Crepidula onyx) encountered from Jindo Island were the species previously recorded in the southern and/or eastern offshores of Korean peninsula, including Jeju Island (Choe, 1992). Along with the fact that Jindo Island contains a large number of molluscan species ranging over the Yellow Sea coast, this finding is another line of evidence supporting the Kim and Kwon (1983)'s idea that this area is an overtopping zone of marine organisms which dwell in both the Yellow sea and southern part of Korean sea waters. No comprehensive faunistic survey was not made in the present study. We expect that further supplementary study would generate more biogeographic and faunistic knowledges than what we understand through the present study.
