Scarabaeids and white grubs were investigated at Halla arboretum and nursery in Jeju province in 1999 and 2001. Scarabaeid pests were surveyed from 14 tree species of 12 families at Halla arboretum in Jeju in March, 1999 and from 55 species of 27 families in March and September, 2001 and from Taxus cuspidata at nursery in Seoguipo in March, 1999 and 18 tree species of 9 families at the same nursery in March and September, 2001. Six species of white grubs and scarabaeids were collected from Halla arboretum. At Halla arboretum, Holotrichia niponensis was collected from 28 tree species of 21 families, H. diomphalia from 27 tree species of 20 families, and an unidentified white grub from 27 tree species of 19 families. Maladera orientalis was collected from 4 tree species of 4 families and Aphodius sp. and Adoretus tenuimaculatus from Punica granatum and Carpinus sieboldiana. At Halla nursery in Seoguipo, H. niponensis were collected from 9 tree species of 6 families and H. diomphalia from 10 tree species of 6 families. White grub of Minela testaceopes was collected from Ternsstraemia japonica. H. niponensis, H. diomphalia and an unidentified white grub were dominant species out of collected white grubs and scarabaeids and these were collected from Cinamomum camphrora. H. niponensis was the most serious pest on T. cuspidata.

This study was carried in Mt. Paektu on the border between North Korea and China. The dominant communities of evergreen broad-leaved trees were Rhododendron aureum community, Dryas octopetala var. asiatica community, Rhododendron redowskianum community and Phyllodoce coerulea community. The evergreen broad-leaved trees investigated consist of a total 34 taxa : 4 forms, 16 varieties, 14 species, 10 genera, 5 families in Mt Paektu and North Korea(in literature). The soil organic matter and available phosphorus were different according to plant community and altitude.

The fish community within the lake and 5 tributaries of Lake Chungju in spring and autumn, 2009 was surveyed. In this study, the total 128,506 individuals were collected belonging to 11 families 29 genera 34 species. The most dominant species was Squalidus japonicus coreanus that account for 91.6% of population and 49% of biomass of fish community. In the point of population, dominant species were small-sized species, which became the prey of big-sized predatory species. In the point of biomass, dominant species were predatory species which were large-sized. The most dominant species in lacustrine area was S. japonicus coreanus which accounted for 92.2% of total population and 49.1% of total biomass. The most dominant species of tributary streams was Tridentiger brevispinis which accounted for 66.4% of total population and 55.1% of total biomass. The site of C3 in lacustrine area and Dongdal-cheon in tributary streams collected the most number of species. Through ecological health evaluation of five tributary streams using 8 metric index of biological integrity (IBI) model, two streams (Dongdal-cheon, Kwang-cheon were evaluated as, "B", "good" condition, and Jangsung-cheon obtained grade C indicating "Fair" condition, Jecheon-cheon obtained grade D indicating "Poor" condition based on IBI model. Lepomis macrochirus which was designated as a domestic ecosystem-disturbing alien species with wide food niche have shown tendency to increase the number of individuals since 1991 indicating the adverse effect on not only fish community but also aquatic ecosystem food web of Lake Chungju.

The study aims at analyzing a species composition of the fish live in bottom of the coastal waters off Sejon island, Korea. To reach the goal of the study, a species composition and it's seasonally fluctuation, a seasonally fluctuation of the dominant species and it's appearance type were analyzed with the fishes caught by the bottom trawl in the coastal waters off Sejon island from May, 2011 to March, 2012. The results obtained can be summarized as follows; Fish caught in this area composes 10 orders, 25 families, and 37 species. The most dominant species in an number of fish was Pennahia argentata which was occupied at 42.1% from the whole number, the second most dominant species was Konosirus punctatus which was occupied at 14.2%. The most dominant species in a biomass of fish was Pennahia argentata which was 31.3% out of the whole catch, the next dominant species was Lophius litulonwhich which was 18.2%. The first group (Trichiurus lepturus, Zeus faber, Pennahia argentata, Chelidonichthys spinosus and Lophius litulon) was appeared at May, August, October, the second group (Sphyraena pinguis) was appeared at May and November, the third group (Pampus argenteus) was appeared at August, the fourth group (Pampus echinogaster, Leiognathus nuchalis, Konosirus punctatus and Engraulis japonicus) was appeared at March.

This study was conducted from March to October 2003 to investigate the distribution status and environmental index of naturalized plants at 14 sites at rivers penetrating the downtown area of Gwangju Metropolitan City. The flora consisted of 309 taxa, 76 families, 211 genera, 273 species, 35 varieties and one form, while the naturalized plants consisted of 46 taxa, 14 families, 36 genera, 44 species and two varieties. The dominant species of Gwangju-cheon were nine taxa. Panicum dichotomiflorum, Rumex crispus, Chenopodium album, Trifolium repens, Veronica persica, Ambrosia artemisiifolia var. elatior, Aster pilosus, Bidens frondosa and Taraxacum offici-nale. The dominant species of Hwangryong River were five taxa: Rumex crispus, Trifolium repens, Oenothera odorata, Ambrosia artemisiifolia var. elatior and Erigeron canadensis. At Yeongsan River appeared 16 dominant species: Patspalum distichum, Ckenopodium ficifolium, Lepidium apetalum, Erigeron annuus and Xanthium strumarium in addition to the same dominant species of Gwangju-cheon and Hwangryong River The Urbanization Index (UI) was 17.2% and the Naturalized Index (NI) was 14.9% at urban rivers of Gwangju. The naturalized plants consisted of 16 taxa, which originated in both Europe and North America. Based upon the UI and NI, the urban rivers and their riversides must be considered a major corridor for the invasion of naturalized plants.

This paper was the result of investigation on fish fauna of natural estuary at Seomjin River, Korea. The total number of fish species collected in this study was 68 species belonging to 26 families. Dominant species in number was Acheilognathus majusculus (relative abundance: 37.4%), subdominant was Tribolodon hakonensis (10.5%). There were seven migrating fishes including Anguilla japonica and T. hakonensis. There were twenty Korean endemic species including Acheilognathus koreensis and Acheilognathus somjinensis. Thirty five species belonging to eight families were collected in upper part of river that dominant species was A. majusculus (38.2%). Thirty seven species were collected in lower part of river that dominant species was A. majusculus (48.5%). Thirty four species were collected in near estuary that dominant species was T. hakonensis (42.6%). In the comparison result of condition factor for several main species populations of Seomjin River were better than Nagdong River populations having estuary barrage. It was considered that almost fish populations of mid-to lower Seomjin River without estuary bank have stable life with natural environment.
