Research Summary

  • 해양섬모충 군집을 연안 환경과 외양수괴의 지표생물로 이용하기 위하여 황해에서 오염정도가 다른 4곳을 택하여 6번의 현장 조사를 수행하고 분석하였다. 총 78종의 섬모충류가 동정되었고,수질화학인자가 분석되었다.그결과 연안 오염의 상태를 평가하는데 화학인자에의한 수질 분석과 단순한 종수와 풍부도 분석 보다는 섬모충의 종수와 풍부도를 활용한 마갈레프 다양성 분석이 수괴 부영양화를
    분석하는데 유용함을 보여 주었다.또한 부영양화 증가에 따라 섬모충류 우점개체군이 식성형에 따라 조류식성형에서 박테리아 식성형으로 변하였다.해양섬모충류에서 2종의 빈여양성 종과 1종의 부영양 지표종이 추출되었다.
    쿠로시오 지표섬모충을 포함한 지표 동식물플랑크톤을 이용하여 황해난류수괴의 황해 유입 정도를 평가하였다.그결과 다수의
    쿠로시오 지표 동식물플랑크톤이 황해내에서 동계,하계,추계에 발견되었고,이는 황해 난류수의 유입을 암시하는 것으로
    쿠로시오 지표 플랑크톤이 난류수의 유입과 지구 온난화를 평가하는데 유용함을 보여주었다.

  • Marine ciliate communities were assessed as indicators of coastal water quality based on samples collected from six cruises at four stations of different pollution status in the Yellow Sea in summer 2000. A total of 78 ciliate species/taxa were isolated and the ciliate communities were characterized by tintinnids and <30 ?m aloricate ciliates. Our study indicates that simple chemical evaluation as well as eutrophication index was limited in assessing the integrated pollution status of the coastal waters which were stressed by various pollutants. Likewise, neither the number of species nor abundance has any correlation with main chemical factors or chemical evaluation indices. By contrast, Margalef?s diversity index which combines the species number and abundance indicates an integrated monitoring of marine pollution effects and discriminates the water quality status of the four stations. The evaluation is also supported by the total number of species found at each station. With increasing eutrophication, we observed compositional and functional shifts of ciliates from the algivorous oligotrich/choreotrich dominance through nonselective-omnivorous gymnostomatid dominance to bactivorous-detrivorous scuticociliatid dominance. Tintinnopsis baltica and Favella ehrenbergii were assessed as indicators of low levels of nutrients/eutrophication, and Uronema marinum as an indicator of eutrophication/organic-rich and oxygen-poor environment.
    Kuroshio indicter species of plankton were useful to analyze the envionment of watermass in the Yellow Sea and the intrusion
    of the Yellow Sea Warm Current.We found the intrusion of the Yellow Sea warm Current in summer,Autumn and Winter by the analysis on the distribution of kuroshio indicater species.

  • Abstract
  • 해양섬모충류 군집을 연안수질의 지표생물로 이용하기위하여 황해에서 오염정도가 다른 수질에서 현장조사를 실시하여 화학인자와 함께 섬모충류 군집을 분석하였다.총78종의 섬모충류가 분리동정되었고,수질화학인자를 분석하엿다.그결과 연안의 오염상태로 화학인자와 함께 섬모충류의 종수와 개체수를 이용한 마칼레프 다양성 지수가 오염정도를 표시하는데 유용함을 보여 주었다.또한 부영양화 정도에 따라 조류식성섬모충에서박테리아 식성섬모충류가 우점종의 변화가 일어 남을 발견하였고,2종의 빈영양성섬모충류와1종의 부영양성 섬모충류를 추출하였다.또한 황해에서의 황해 난류수의 유입과 지속성을 평가하기 위하여 쿠로시오 지표 플랑크톤의 분포를 6차에 걸친 현장자료를 이용하여 분석하였다 그결과 황해난류수가 겨울과 여름,가을에 황해로 지속적으로 유입함을 발견하였다.
