초록

본 연구는 한국산 도롱뇽 유생(Hynobius leechii)을 대상으로 간접적인 카니발리즘 경험이 표현형에 어떠한 영향을 미치는지 알아보기 위하여 2011년 3월부터 4월까지 수행되었다. 우리는 유생의 생활사 초반에 개체 주변에서 발생하는 동종의 카니발리즘(간접적인 카니발리즘 경험)을 통하여 나타날 수 있는 폴리페니즘에 대하여 조사하였으며, 폴리페니즘의 발생 요인을 알아보기 위하여 간접적인 카니발리즘을 경험하는 그룹과 그렇지 아니한 그룹으로 나누어 실험하였다. 두 그룹의 도롱뇽 유생의 머리 중 가장 넓은 곳의 길이(LHW), 눈이 있는 부분의 길이(HWE), 코끝부터 항문(SVL)까지의 길이를 측정하였다. 또한 HWE를 LHW로 나누어 비율을 구한 후 통계처리를 하였다. 그 결과 유생의 생활사초반에 간접적인 카니발리즘에 노출될 경우 그렇지 못한 그룹보다 머리크기의 비율(HWE/LHW)이 의미 있게 증가하는 것을 볼 수 있었다. 이러한 결과를 통하여 도롱뇽유생은 주변의 다른 개체들로부터 전달되는 화학신호에 민감하게 반응하는 것을 알 수 있었다.

This study was conducted to demonstrate the relationship between experience of cannibalism and difference of phenotype in the Korean salamander Hynobius leechii from March to April 2011. We examined whether the different polyphenism of larval salamander is induced as a result of indirect cannibalism in early life cycle. We divided into two groups(one group continuously exposed to the indirect cannibalism and the other group never exposed to the cannibalism). We measured the head width at the level of eyes(HWE), the largest head width(LHW) and snout-vent length(SVL) of the each larva then calculated the ratio of the head size by dividing HWE by LHW. We found that exposure of indirect cannibalism in early life cycle cause the different polyphenism. Our result means the larval salamander responded to the chemical cue from conspecific.
