초록

일시적으로 조성되는 수환경에 서식하는 갑각류에 속하는 긴꼬리투구새우는 현존하는 화석생물로서 외국에서는 분포, 형태 및 번식 등 다양한 연구가 수행되었다. 그러나 우리나라에서는 환경부 지정 멸종위기야생동물로 지정될 만큼 희귀생물임에도 불구하고 기초연구가 매우 미흡하다. 본 연구는 한국산 긴꼬리투구새우 (T. longicaudatus)의 분포와 서식지의 특성을 파악하기 위하여 2006년 5월부터 2008년 7월까지 조사를 수행하였다. 조사결과 긴꼬리투구새우는 남한의 21개 지역의 논과 일시적으로 형성된 웅덩이에 서식하는 것으로 밝혀졌다. 긴꼬리투구새우는 조사기간 중 주로 5월에서 7월 사이에 발견되었으며, 이때 서식지의 온도범위는 약 $10.7{\sim}33.5^{\circ}C$ 이었으며, 서식지에서 약 30일 정도 생존하는 것으로 확인되었다. 환경요인 중 서식지의 평균 혼탁도는 176.8 (${\pm}239.3$) NTU로서 대조구로 선정한 논 ($28.9{\pm}26.7$ NTU)보다 상당히 높게 나타났다. 본 연구를 통해 긴꼬리투구새우는 일시적으로 형성되는 환경에 비교적 잘 적응하는 종이며, 물대기와 같은 영농활동이 이들의 개체발생과 생장에 큰 영향을 미치는 것을 확인하였다.

Tadpole shrimps are aquatic crustaceans adapted to temporary water pool. Since they have been recorded as the living fossil, there are a number of reports on their past and present distribution as well as their morphology and reproduction in foreign countries. However, there are few studies of biology and ecology of tadpole shrimps despite registration as an endangered species by Ministry of Environment, in Korea. This study was carried out to examine the distribution and habitat characteristics of tadpole shrimps (Triops longicaudatus) collected from May 2006 to July 2008 in Korea. Tadpole shrimps were found from the paddy fields and ephemeral pools at 21 countries in South Korea. They appeared between May and July and survived for 30 days, and temperatrue range was $10.7^{\circ}C$ to $33.5^{\circ}C$. The average turbidity of experimental paddy fields was 176.8 (${\pm}239.3$) NTU, and controlled field was 28.9 (${\pm}26.7$) NTU. The life pattern of tadpole shrimps is adapted to a temporary water pool and unstable environmental conditions, and also there was great effect of agricultural activity on the development and growth of tadpole shrimps.
