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 sc...

종의 장거리 산포는 어떤 역할을 하는가? | 2008). 종의 장거리 산포는 집단의 확산, 집단간 개체 흐름 등의 대규모 과정을 결정하는데 중요한 역할을 하고, 종 침입요소는 공급원과 이동경로, 그리고 정착지로 이루어지며, 침입력이 커질 확률은 개체군의 초기 크기와 새로운 서식처의 조건과도 관계가 있다(Park et al. 2002; Nathan et al. | |
본 연구에서 발견된 참빗살나무 분류군은 어떤 문제가 있었는가? | )로 판단된다 (Lee 1980, 2003; Kim and Kim 1994a; Lee 1996). 그러나, 발견된 분류군은 생식기관이 없는 어린 개체이고, 기상 등 독도의 접근성이 어려움에 따라 생식기관을 확인하는 것이 용이하지 않으므로 분자자료를 이용한 객관적인 확인이 요구된다. | |
화살나무속은 무엇인가? | 화살나무속(Euonymus L.)은 주로 화서의 형태, 약실의 수 등 형태형질을 주요 식별형질로 사용하고 있으나 식별형질의 중복현상과 변이가 심하여 많은 혼란이 야기되고 있는 분류군이다(Kim and Kim 1994b). 채집된 개체는 영양기관인 줄기와 잎으로 식별이 용이하지 않으나, 소지(twig)는 원주형이고, 표면에 부속물이 없는 평활한 유형이며, 잎은 피침상 장타원형이고 첨두, 그리고 기타 외부 형태적 특징 등이 참빗살나무 (Euonymus hamiltonianus Wall. |
