Abstract

The present scientific scenario shows that, the long-distance dispersal of any species plays a major role in population as well as the flow of individual between populations. However, newly recorded plant at Dokdo was confirmed by using morphological and molecular markers of nrDNA and cpDNA. This scientific study has identified the plant species was as a Euonymus hamiltonianus Wall. (Celastraceae). And after careful studies, the laboratory results shows that the distribution of tree species at Dokdo as an Oceanic Island is a meaningful thing because of the inflow of plant in adverse condition of environment such as a shallow soil layers and steep terrain. So it is necessary to continuous monitor for the inflow of non-indigenous plant into Dokdo.

종의 장거리 산포는 집단의 확산과 집단간 개체의 흐름에 중요한 역할을 한다. 본 연구는 독도에서 발견된 식물을 형태학적 특징과 핵 및 엽록체 DNA의 분자마커를 이용하여 종을 식별한 결과, 참빗살나무 (노박덩굴과)로 확인되었다. 얕은 토양층과 험준한 지형 등 입지적으로 열악한 대양섬인 독도에서 목본의 분포는 의미있는 결과이며, 향후 외부유입종의 지속적인 모니터링이 요구된다.
