Naturalization centers are hotspots where accidently introduced seeds first germinate and grow. Railways play important roles as corridors for movement, which have positive effects on species dispersal and persistence; they can also be invading routes for undesirable plants. Geranium purpureum Vill., a new alien species in South Korea, was found in...

털개구리자리(Ranunculus sardous Crantz)는 유럽 원산으로 미국, 오스트레일리아, 중국 및 일본의 해안가을 중심으로 분포역이 확대되어가고 있는 종이다. 2018년 제주 지역의 식물조사에서 털개구리자리를 발견하였으며, 발견된 서식지는 제주 서귀포시 하논 지역으로 저지대의 습한 지역이다. 털개구리자리는 엽신이 3갈래로 갈라지며, 꽃받침이 뒤로 젖히는 등 근연분류군인 개구리자리(R. seleratus L.)와 형태학적으로 매우 유사하다. 그러나 개구리자리는 식물체 전체에 털이 없거나 드물게 있으며, 열매가 난상 타원형 또는 타원형이고, 수과는 약간 부풀지만, 털개구리자리는 식물체 전체에 털이 밀생하며, 열매...

북한산국립공원은 우리나라 15번째로 지정된 국립공원으로서 도심 지역 위치하여 접근이 용이하고, 수려한 경관의 자연휴식처로써 국내 22개 국립공원 중 탐방객 수가 가장 많은 곳이다. 최근 북한산국립공원 일대에 생태계 교란종이 빠르게 확산되어 생태 환경이 위협받고 있다. 따라서 본 연구는 의도적 또는 비의도적으로 북한산국립공원 지역에 광범위하게 확산되고 있는 생태계 교란종의 효율적인 관리와 제거를 위해 이들의 분포현황을 파악하고자 북한산국립공원 21개 둘레길 중 백운대 정상을 중심으로 한 13개 둘레길 내 150개 지점에 대한 전수조사를 수행하였다. 그 결과 약 17,175개체의 생태계교란종(돼지풀, 단풍잎돼지풀 2종)이...

한반도의 고표본은 20세기 초반 많은 외국학자들에 의해 수집되었으나 대부분 국외에 소장되어 있으며 자국의 언어로 기재되어 채집지를 추적하는데 어려움이 있다. V. L. Komarov, U. Faurie, 그리고 T. Nakai 등에 의해 국내에서 채집된 식물들은 여러 연구자들에 의해서 정리되고 있으나, 아직도 확인되지 않은 한반도 표본에 관한 연구는 미진하다. 본 연구는 러시아의 동물학자인 Pyotr Yul'evich Schmidt의 한반도 채집에 대한 문헌과 이와 관련된 표본이 발견되어 P. Schmidt의 한반도 채집이동경로를 조사하였다. 문헌은 한반도 제1차 원정보고서, 그의 저서, 그리고 각 저널에 인용된 기록들...
