우면산 일대의 저서성 대형무척추동물상

Benthic macroinvertebrates fauna was investigated at the Mt. Umyeon, Seoul, Korea, from July to September, 2012. Umyeon(Reg. 1) and Seoul Arts Center(Reg. 2) were selected for quantitative (Dredge, 50×50cm, mesh size 1mm) and qualitative(Hand net) sampling of benthic macroinvertebrates. Including qualitative sampling, total 26 species occurred. They were composed of 1 species in Planariidae, 1 species in Lymnaeidae, 1 species in Gammaridae, 2 species in Ephemeroptera, 2 species in Odonata, 1 species in Plecoptera, 7 species in Hemiptera, 2 species in Coleoptera, 8 species in Diptera, 1 species in Trichoptera. Total taxa of benthic macroinvertebrates collected by quantitative sampling were 19 species, 10 families, 7 orders, 2 classes, and 1 phyla. The dominant species and the subdominant species based on abundance was Chironomidae sp. 1 and Cloeon dipterum with 45.6% and 19.0% of dominance respectively. Diversity index and richness index of benthic macroinvertebrates showed the range of 2.62∼1.76 and 1.95∼1.39 respectively.
