초록

물거미(Argyroneta aquatica)는 전 세계적으로 한 종만 존재하는 희귀거미로 수중에서 살며, 국내 서식지인 경기도 연천군 은대리는 천연 기념물 서식지로 지정되어 있다. 그러나 은대리 습지대는 근래 들어 육지화 현상이 이루어져 서식지 손실이 나타나고 있다. 서식지 손실은 물거미 개체수에 직접적인 영향을 미치므로 물거미 보호 조치가 필요하다. 곤충은 생태계 기저에 위치하며, 대상환경의 특징을 직, 간접적으로 대변한다. 물거미 서식지 보호 방안 및 2015년 5월에서 9월 사이 물거미 서식지와 그 주변의 곤충상 조사를 쓸어잡기(sweeping)와 육안조사로 실시하였으며 조사한 곤충군을 군집분석하였다. 곤충상 조사 결과 총 13목 276종 3,929개체가 채집되었다. 가장 많이 채집된 곤충군은 노린재목으로 전체 채집종의 24.2%, 채집 개체의 82.3%를 차지했다. 채집된 전체 곤충상의 군집분석 결과, 우점도 지수는 0.23, 다양도 지수는 2.27, 균등도 지수는 0.41, 풍부도 지수는 31.2로 나타났으며, 이전 조사 자료 결과와 비교하면, 가장 빈번하게 수집된 종이 육상곤충으로 바뀌었고, 이는 물거미의 습지 서식지가 육지 환경으로 빠르게 변화함을 보여주었다.

The water spider (Argyroneta aquatica), a rare member of its species, is one of the few insects known to live under water all over the world. In Korea, the water spider can be found only in the Eundae-ri, Yeoncheon, Gyeonggi province, where they are designated as a natural monument. However, loss of habitat is obvious, as the Eundae-ri wetland undergoes hydrarch succession. Loss of habitat has a direct impact on the water spider population. Thus protective measures for the water spider are needed to preserve the water spider habitat. In this study, a sweeping and visual survey of insect species was conducted in the water spider habitat from May to September 2015. The characteristics of each one of the different insect species and the community features were analyzed in this study. A total of 3,929 insects representing 276 species from 13 orders collected for the analysis. The most frequently collected insects from the Order Hemiptera represented 24.2% of total species and 82.3% of the total number of insects. Community analyses showed dominance, diversity, evenness, and richness indices of 0.23, 2.27, 0.41, and 31.2, respectively. Compared with the previous survey data, these results showed that reduction of the spider's wetland habitat caused the most commonly collected insects to adapt and spread to the surrounding terrestrial environment.
