  • This study carried out to certify of taxonomic delimitation in A. artemisiaefolia, A. trifida, A. trifida for. integrifolia, and A. psilostachya in the area of literature and experiment. A. psilostachya was not a vestige of naturalized in Korea and A. trifida and A. trifida for. integrifolia didn't have any valuable differences of morphological and molecular biological experiment. I arranged that naturalized species in Ambrosia are A. artemisiaefolia L. and A. trifida L. in Korea.

  • The vascular plants species were summarized as 479 taxa: 89 families, 260 gents, 404 species, 66 varieties, 8 forms and 1 hybrid in the whole 6 surveyed areas of eastern parts of Jirisan (Georim Valley, Baengmudong Valley, Hanshin Valley, Jungsanri Valley, Sesokpyongjeon, and Chonwangbong). Based on the list of Korean endemic plants, 26 species were recorded: Athyrium excelsius (Aspidiaceae), Abies koreana (Pinaceae), Betula ermani var. saitoana (Betulaceae) etc. The special plants from the list of Ministry of Forest, the Forest Research Institute (1997) and the Ministry of Environment (2001), 15 species were recorded: Smilacina bicolor (Liliaceae), Disporum ovale (Liliaceae), Clematis chiisanensis (Ranunculaceae) etc. And 15 species of naturalized plants were recorded: Oenothera biennis (Onagraceae), Ambrosia artemisiaefolia (Asteraceae), Carduus crispus (Asteraceae), etc. Especially, the Korean endemic plants repeatedly appeared around mountain-trails and Ambrosia artemisiaefolia (Asteraceae), also, popular were distributed in the entire studied areas.

  • This study analyzed the distribution characteristics of invasive alien plants on the islands of the Korean Peninsula. Ten species, Rumex acetosella, Sicyos angulatus, Solanum carolinense, Ambrosia artemisiaefolia var. elatior, Ambrosia trifida, Aster pilosus, Eupatorium rugosum, Hypochaeris radicata, Lactuca scariola, and Paspalum distichum were present on 68 islands. These ecosystem-disturbing invasive alien plants appeared extensively on the islands of Gyeonggi province and Jeollanam province. The proportion of the plants on the inhabited islands (41 places, 2.15 species on average) was higher than that on the uninhabited islands (27 places, 1.07 species on average). This means that the distribution of invasive alien plants was closely related to human activity. The distribution of Ambrosia artemisiaefolia var. elatior(32 islands) and Rumex acetosella (31 islands) was the widest, and there were distinct distribution differences according to species. In the island area, the physical environment is poor compared to the mainland, and the native space is limited. Therefore, when invasive alien species enter and settle on the island, the native island plants can be damaged more than those on the mainland. In this regard, the discussion of the distribution of invasive alien plants in the island region can contribute to the conservation of biodiversity in the region.

  • In this study, an on-site survey was conducted around Gasado island at Jodo-myeon, Jindo-gun, Jeonnam during July 2 to 25, 2002. The naturalized plants investigated in the surveyed sites were revealed 15 families and 39 species, including Althaea rosea and Oxalis articulata, which are ornamental plants. Only 10 species appeared in Imjado island among the surveyed sites the surveyed sites and Imjado Island, including Elymus sibiricus, Lolium perenne, Chenopodium album, Oxalis articulata, Oxalis corymbosa, Oenothera odorata, Xanthium strumarium, Bidens frondosa, Ambrosia artemisiaefolia var. elatior, and Taraxacum officinale. 6 species were distributed only in Gasado island, Jindo-gun, which included include Festuca myuros, Chenopodium ambrosioides, Amorpha fruiticosa, Malva neglecta, Calendula arvensis, and Carthamus tinctorius. 18 species were showed in Soheuksan island.; Yeosu area, 29 species; Imja Island in Sinan-gun, 34 species, and Gasado Island in Jindo-gun revealed 39 species. It is believed that the species of naturalized plants have been expanded compared to the other areas because of close location to the inland and large population fastiy. The Urbanization Index(UI) of this area was found to be 19.5. The naturalized plant communites in these surveyed sites were classified into Rumex crispus, Elymus sibiricus, and Lolium perenne community according to the vegetation table. Furthermore, they formed a community around areas that received great artificial influence from human dwellings or roads due to the characteristics of species distribution

  • This study was to investigate water quality and biotic community characteristics in Juam Lake. In water quality, water temperatures was $3.8{\sim}21.2^{\circ}C$, 6.7~8.6 in pH, $64{\sim}76{\mu}s\;cm^{-1}$ in Conductivity, $5.3{\sim}13.2mg\;L^{-1}$ in DO, $2.5{\sim}3.3mg\;L^{-1}$ in COD, $1.0{\sim}5.1mg\;L^{-1}$ in SS, $0.622{\sim}0.841mg\;L^{-1}$ in T-N, $0.007{\sim}0.019mg\;L^{-1}$ in T-P and $2.8{\sim}8.8mg\;m^{-3}$ in Chl-a. Revised Carlson's Index (TSIm) assessment using total phosphorus (TP) and chlorophyll-a domonstrated that the trophic states of Juam Lake were rated as mesotrophic. A total of 53 species of phytoplankton were identified. They were 28 Bacillariophyceae, 13 Chlorophyceae, 3 Cyanophyceae, and 9 Other algal taxa. The standing crops of phytoplankton was ranged from $113cells\;mL^{-1}$ to $2,909cells\;mL^{-1}$. A total of 16 species of zooplankton were identified (10 rotifers, 4 cladocerans and 2 copepods). Total zooplankton abundance was $309ind.\;L^{-1}$ to $435ind.\;L^{-1}$. The collected benthic macroinvertebrates from the surveyed sites in Juam Lake were 1,038 individuals, 33 species, 21 families and 12 orders. A dominant species was Uracanthella rufa and a subdominant species was Ecdyonurus kibunensis. Hydrophytes recorded from Juam Lake were identified 9 taxa. Emerged plants, floating plants among the hydrophytes was classified 8, 1 taxa, respectively. Ecosystem disturbance wildplant by Environment Ministry found were Paspalum distichum var. distichum and Ambrosia artemisiaefolia. A total of 30 species (6 families) were collected fishs from Juam Lake. There were 10 Korean endemic species (33.3% of collected species number) and 3 exotic species (10.0%).
