  • We surveyed the biodiversity of lepidopterous insects in Jindo Island using UV bucket trap in July 2016 to determine the relationship between surrounding environment and ecosystem in order to contribute to biodiversity conservation and management of coastal islands in Korea. Based on our survey results, a total of 262 lepidopterous insect species in 16 families were collected from Jindo Island. Members belonging to families Noctuidae and Geometridae made up approximately half of the total species (86 species [32.82%] in Noctuidae and 44 species [16.79] in Geometridae). There were 29 species (11.07%) belonging to Crambidae and 28 species (10.69%) belonging to Pyralidae. As a result of all collections based on previous literature and this study, a total of 730 species belonging to 34 families were collected from Jindo Island, including 33 protected species, 242 species (33.15%) belonging to Noctuidae (the most abundant), 124 species (16.99%) belonging to Geometridae, 79 species (10.82%) belonging to Crambidae, and 65 species (8.90%) belonging to Pyralidae. The most frequently collected species was Lamoria glaucalis in this syudy. Our results on the diversity of lepidopterous insects will provide basic information for future investigation on diverse changes in the ecosystem of Jindo Island, Korea.

  • Insect fauna were surveyed in 2011 at Ungok wetland, Obeygol, located in Gochang, Jeonbuk, Korea. In total, 149 species belonging to 11 orders and 57 families were surveyed. Among them, Lepidopterans composed 23.5% (35 species) of the total insect numbers surveyed, comprising the most abundant group, and followed by Coleoptera, Hemiptera, and Odonata with a composition of 22.1% (33 species), 17.4% (26 species), and 10.1% (15 species), respectively. Bothrogonia japonica Ishihara was the most dominant species, and followed by Gastrophysa atrocyanea Motschulsky and Celastrina argiolus (Linnaeus). Phytophagous insects accounted for 60 percent of the total species. Dominance index was the highest in spring by 0.21. Diversity, richness, and evenness indices were the highest in summer by 4.07, 11.84 and 0.96, respectively. In the study area, the legally-protect species were grouped into five groups; 9 export-restricted species, 17 endemic species, 28 indicator species, 1 climate-sensitive biological indicator and 3 southern characteristic species. Additionally, twenty forest insect pest species were surveyed, belonging to 5 orders and 15 families. Therefore, it is required to conduct long-term monitoring and appropriate management based on the ecological characteristic of the habitats to continuously conserve and maintain of wetland.

  • The purpose of this study is to fiure out the floral changes during three years after construction of the Youido Ecology Park. Yearly change of plant species composition, distributed at the research field, had been investigated for three years since 1996. To compare and investigate the changes of the establishment of the Ecology Park, we have analyzed the distribution characteristics of plant species, exotic naturalized species, and so on. The results obtained through this investigation are as follows; 1) Total numbers of plant species were 106, 170, 175, and 148, in the year of 1996, 1998 1999, and 2000, respectively. While the most of cultivated species before th establishment were decreased, the naturalized species such Phargmites communis Trin, and Artemisia selengensis Turcz. etc, were increased. 2) Forty three species of exotic naturalized species were investigated and were increased at the early stage of the establishment, but showed decreasing trend recently. 3) Sixty five species of introduced and planted species were investigated. Most of them were occurred at the first year after the establishment, but since 1999, there has been a significant decrease. 4) Sixty seven species among total 235 were verified as the wetland-adapted plants. The ratio to the total numbers were low, but the occupied area of a few species was expanded. Therefore, it indicates that monitoring on the physical environments of the Youido Ecology Park was urgently required.

  • Based upon the vegetation data of woody plants by plot sampling method in the natural deciduous forest of Mt. Jeombong, the study was carried out to examine importance value, rank abundance curve, and species abundance curve, and comparatively evaluate seven different species diversity indices for Shannon-Wiener index, Simpson index, McIntosh index, Log series, Margalef index, Berger-Parker index, and species richness, according to topographic positions. The minimal area which meant only few more species were increased was 3.48 ha in total. The dominant species of valley were Carpinus cordata, Acer pseudo-sieboldianum, Quercus mongolica, Acer mono, and Abies holophylla, and the dominant species of mid-slope were Quercus mongolica, Acer pseudo-sieboldianum, Carpinus cordata, Tilia amurensis, and Fraxinus rhynchophylla. Moreover, the dominant species of ridge were Quercus mongolica, Acer pseudo-sieboldianum, Tilia amurensis, Fraxinus rhynchophylla, and Acer mono. According to rank abundance curve and species abundance curve, species evenness was also low. All of Log series, species richness, Margalef, and Shannon-Wiener index discriminated that valley had the highest diversity, and ridge had the lowest diversity; but, Simpson index, McIntosh index, and Berger-Parker index represented that mid-slope had the highest diversity, and ridge had the lowest diversity. Uniquely, in Berger-Parker index, mid-slope was the higher value than total.

  • The characteristics of insect communities in specific localities reflect climatic and environmental status and change. We investigated the description pattern of new insect species by reviewing announcements of new or newly recorded insects in Korea published in five systematic journals between 1999 and 2009: Entomological Research (1999-2009), Insect Koreana (1999-2003), Journal of Asia-Pacific Entomology (1999-2009), Korean Journal of Applied Entomology (1999-2009), and Korean Journal of Systematic Zoology (1999-2009). A total of 757 new species were reported in 299 research papers. More than 85% of the newly described or reported species belonged to four orders: Coleoptera (225 species), Lepidoptera (202 species), Hymenoptera (141 species), and Diptera (82 species). The number of new species fluctuated from year to year, and a few major authors described most species. The graph of the cumulative number of species described in Korea was not asymptotic. We also examined the decadal trends in the proportion of species according to their biogeographical origin. The numbers of northern (Palearctic and Nearctic) and southern (Oriental) species recorded in Korea between 1999 and 2009 were increasing mainly due to the recent taxonomic research environment. It is also possible that recent climatic change induces new migrants toKorea from more southern parts of Oriental region, but more information is needed to confirm this hypothesis.

  • Here we describe indigenous prokaryotic species in Korea, a total of 42 bacterial strains affiliated to the class Alphaproteobacteria isolated from various environmental samples: fermented vinegar, sea water, beach sand, fresh water, salt flats, moss, algae, activated sludge, and soil. From the high 16S rRNA gene sequence similarity (>98.7%) and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to predefined bacterial species. There is no official report that these 42 species included in Alphaproteobacteria in Korea: 15 species of 6 genera in the order Rhodospirillales, 12 species of 10 genera in the order Rhizobiales, 10 species of 8 genera in the order Rhodobacterales, 4 species of 4 genera in the order Sphingomonadales and 1 species of 1 genus in the order Caulobacterales. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are also described in the species description section.

  • The purpose of this study is to provide an protected wildlife species and potential habitats in Seoul through the overall present status of the species which live in Seoul. This study was performed in Seoul, the entire area of which is 605.52 $km^2$. We analyzed a total of 57 studies, including academic papers and research reports, for the natural ecology in Seoul. As for the results from the study, it was found that a total 1,907 species from 5 taxa were inhabiting and growing within the area. Among the total, plants of 1,656 species accounted for 86.7%, 197 species of wild birds made up 10.3%, 29 species of amphibians and reptiles consisted of 1.5%, and 27 species of mammalia totaled 1.4%. A total of 440 species except foreign species and species legally preserved by the Ministry of Environment, common species and uncertain species were selected as primary candidates. By taxon, it shows 212 species of plants, 180 species of wild birds, 24 species of mammalia, and 24 species of amphibians and reptiles. For extensive research subjects and research data limited in certain insect family, analysis by literature for discovered insects was excluded. The selection criteria for the second candidate species was based on extinction crisis, rarity, historicity and locality, academic value, habitat specificity, etc. The second candidate species from the primary species were selected through taxon experts' evaluations. As for the results of the selection of the second candidates, a total 77 species were selected through the experts' evaluations. Each species by taxon was 25 species for plants, 21 species for wild birds, 5 for mammalia, 10 for amphibians and reptiles and 16 species for insects. A site investigation for the second candidates was conducted to select the final candidate species. For the target areas, the habitats of the second candidates given by the literature and 46 potential areas in Seoul, which show good natural resistance, were finally selected. From the result of the site investigation, it was found that 14 species of plants, 19 species of wild birds, 2 species of mammalia, 4 species of amphibians and reptiles, and 16 species of insects were actually inhabiting Seoul; thus, the final 55 protected species were selected.

  • This study was carried out to identify the relationship between naturally introduced vegetation on the abandoned coal mine lands and the surrounding forest, and to select the indigenous tree species for the revegetation of the real mine lands in Taeback, Kangwon Province, Korea. The apparent species in the surrounding forest of Sododong were 9 species of tree layer, 13 species of subtree layer, 23 species of shrub layer and 23 species of herb layer, respectively. The dominant species in Sarijae were 6 species of tree layer, 15 species of subtree layer, 31 species of shrub layer and 25 species of herb layer, respectively. The plant species in the abandoned real mine land were 31 species in Sododong and 30 species in Sarijae, respectively. The number of plant species in the abandoned coal mine land was smaller than the surrounding forest. The common species of the coal mine lands and the surrounding forest were 6 species(Betula schimidtii etc.) in Sododong and 4 species(B. costata etc.) in Sarijae. It was considered that the species in the coal mine lands introduced from the species of top layer in the surrounding forest. Especially, B. costata in Sarijae showed the edge effect which regenerates the vegetative community from the boundary area of coal mine land and surrounding forest. Natural revegetation in Sododong was also progressing by the invasion of tree species in surrounding forest, such as B. schmidtii. Consequently, natural revegetation in the disturbed coal mine lands may be related to the species composition of the surrounding forest.
