  • 북한 신포지구에 위치하는 3개 호수는(호만포호, 현금호, 대인호)동물플랑크톤 출현 결과와 염분도로 (현금호는 2002년 5월과 10월에 2.8ppt와 0.8ppt, 대인호는 1.5ppt와 0.5ppt) 보아 기수호임이 밝혀졌다. 3개 호수에서 출현한 34종류의 동물플랑크톤 중 요각류와 윤충류가 각각 15종과 7종 동정되었으며 34종류 중 담수종은 24종, 기수종과 해산종은 각각 6종과 4종이었다. 기수성 요각류인 Pseudodiaptomus와 Sinocalanus tenellus는 3개 호수에 모두 분포하고 있었으며 3개 호수 모두에서 기수종과 해산종의 출현양이 동물플랑크톤 출현양의 90%이상을 차지하고 있었다. 5월에 현금호에서 S. tenellus가 입방미터당 59,000개체로 대량 출현하여 이때 기수종과 해산종의 출현양은 전체 동물플랑크톤 출현양의 99%를 넘었다. 연구 지역의 기수호를 보호하기 위한 기초자료를 제공하기 위해서는 장기 조사가 필요한 것으로 나타났다.

  • Eight calanoid species of 4 genera in 4 families are reported from the various brackish waters such as estuaries, brackish-water lakes, and coastal marshes in South Korea. Among them, Eurytemora affinis (Poppe) and Acartia (Acanthacartia) tsuensis Ito are newly added to Korean copepod fauna. Collection data, brief descriptions, illustrations and distribution maps for the eight species are prepared. A key to the genera and species of the brackish-water calanoids from Korea is also presented.

  • As one of the serial faunistic studies on the brackish cyclopoids from Korea, taxonomic accounts of three species of Halicyclops from various brackish waters in South Korea are provided, with detailed illustrations of them: H. uncus Ueda and Nagai, 2009, H. setiformis Ueda and Nagai, 2012, and H. itohi Ueda and Nagai, 2012. Halicyclops uncus is newly recorded from Korea, and the latter two species are corrected from H. sinensis sensu Chang, 2009 and H. cf. rotundipes sensu Chang, 2009, respectively. As a result, a total of seven species of the genus are now recognized in Korea, and a revised key to the species is presented.

  • Four harpacticoid species belonging to the family Tachidiidae are reported from the coastal waters and salt marshes in South Korea: Tachidius discipes Giesbrecht, 1881, Neotachidius parvus Huys, Ohtsuka, Conroy-Dalton and Kikuchi, 2005, Microarthridion litospinatus Shen and Tai, 1973 and Geeopsis incisipes (Klie, 1913). The latter two species and genera are new to Korean fauna. The previous record of T. discipes reported by Song and Chang (1995) from Korea is affirmed by the finding of male specimens. Microarthridion litospinatus is first known outside the type locality, and redescribed herein in detail. A key to the five species and four genera of the family Tachidiidae hitherto known from South Korea is presented.

  • 2015년 10월부터 2016년 7월까지 가을, 겨울, 봄, 여름의 계절별로 한강 하구의 시암, 성동, 공릉천, 산남, 장항습지 등 5개 습지에서 동물플랑크톤 채집을 실시하였다. 25종의 윤충류를 포함하는 총 46종류의 동물플랑크톤이 출현하였다. 기수종은 요각류 2종만이 출현하였고 10월에 성동과 장항습지에 출현한 15종류가 가장 다양하게 출현한 것이었다. 최대 출현량은 3월에 시암습지에서 윤충류의 대량 출현에 의해 $8,000indiv.\;L^{-1}$로 기록되었다. 3월에는 다른 정점에서도 $5,000indiv.\;L^{-1}$ 이상의 높은 출현량이 나타났지만 나머지 기간 중에서 수백 개체의 낮은 밀도가 지속되었다. 종다양성지수는 0.4~1.8 사이에서 변동하였다. 요각류 유생의 장내용물질 분석 결과 미동정물질들과 함께 규조류가 주먹이원인 것으로 밝혀졌다. 수온은 $10.1{\sim}28.2^{\circ}C$, pH는 7.1~8.6 용존산소량은 $4.5{\sim}11.0mg\;L^{-1}$ 사이에서 변동하여 정점에 따라 하계 수온상승에 의한 용존산소량 부족 가능성이 제기되었다.

  • Three brackish-water harpacticoid species belonging to the family Cletodidae are reported from the salt marshes in South Korea: Limnocletodes behningi Borutzky, 1926, L. angustodes Shen and Tai, 1963 and Kollerua longum (Shen and Tai 1979). Two genera, Limnocletodes and Kollerua, and the three species are newly added to Korean fauna. This paper deals with the redescription and systematic accounts of them, with detailed illustrations.

  • In order to examine the transition of zooplankton community by the Saemangeum sea dyke, the temporal and spatial distribution of zooplankton community with relation to environmental variables was investigated using data collected in 2004 and 2005. Sixty-one zooplankton taxa were identified. Average abundance (except Noctiluca scintiliam) ranged from 236 to 1810 indiv. $m^{-3}$, and was the highest in May 2005 and the lowest in february 2005. Dominant species were Acartia hongi and Paracalanus indicus, and cirripedia nauplii and zoea were dominant groups. After the closure of the 4th sea dyke, brackish species such as Tortanus derjugini and Pseudodiaptomus inopinus are widely distributed while the abundance of N. scintillans decreased in the northern area inside the dyke. In canonical correspondence analysis (CCA) for examining the relationships among zooplankton, stations and environmental variables, the northern area inside the dyke was distinguished from the other areas and was represented by Acartia spp, and brackish copepods.; Also, this area was characterized by high chlorophyll a concentration and COD, and low diversity.
