Most wetlands worldwide have suffered from extensive human exploitation. Unfortunately they have been less explored compared to river and lake ecosystems despite their ecological importance and economic values. This is the same case in Korea. This study was aimed to estimate the assemblage attributes and distribution characteristics of benthic macroinvertebrates for fifty wetlands distributed throughout subtropical Jeju Island in 2021. A total of 133 taxa were identified during survey periods belonging to 53 families, 19 orders, 5 classes and 3 phyla. Taxa richness ranged from 4 to 31 taxa per wetland with an average of 17.5 taxa. Taxa richness and abundance of predatory insect groups such as Odonata, Hemiptera and Coleoptera respectively accounted for 67.7% and 68.2% of the total. Among them Coleoptera were the most diverse and abundant. Taxa richness and abundance did not significantly differ from each wetland type classified in accordance with the National Wetland Classification System. There were three endangered species (Clithon retropictum, Lethocerus deyrolli and Cybister (Cybister) chinensis) and several restrictively distributed species only in Jeju Island. Cluster analysis based on the similarity in the benthic macroinvertebrate composition largely classified 50 wetlands into two major clusters: small wetlands located in lowland areas and medium-sized wetlands in middle mountainous regions. All cluster groups displayed significant differences in wetland area, long axis, percentage of fine particles and macrophyte composition ratio. Indicator Species Analysis selected 19 important indicators with the highest indicator value of Ceriagrion melanurum at 63%, followed by Noterus japonicus (59%) and Polypylis hemisphaerula (58%). Our results are expected to provide fundamental information on the biodiversity and habitat environments for benthic macroinvertebrates in wetland ecosystems, consequently helping to establish conservation and restoration plans for small wetlands relatively vulnerable to human disturbance.
산업곤충의 도입 및 관리체계에 있어 사전예방적 조치가 비용효과적임에도 불구하고 차단격리 시설의 미비 등 이들 외래 유해 곤충종들의 유입을 효과적으로 예방하는 체제를 갖추지 못하고 있는 실정이다. 현재 우리나라는 산업곤충의 정확한 범주에 따른 관리시설의 설치규정안과 그에 따른 설치시설이 전무함에 따라 ACLs과 같은 외국의 절지동물 격리시설의 기준안과 우리의 연구시설 등을 포함한 격리 시설에 적용 가능한 기준안을 검토해 보았다. 1차적으로 산업곤충의 유형을 특성에 맞게 구분해 보았으며 유형에 따른 설치안과 더불어 시설설치 기준안에 필요한 구성요소들을 살펴보았다. 또한, 주로 실험동물을 대상으로 한 LMO 연구시설의 설치 및 운영 세부항목들을 포함하여 금번 연구 분석 자료를 바탕으로 위해성 곤충류의 격리에 필요한 시설의 설치와 운영기준을 고찰해보고자 하였다.
