As a study for offshore wind farm, we investigated the fish fauna of the Wi-do, Younggwang-gun, Chollabuk-do, Korea. From the four times collection of fish species from October 2013 to June 2014, we collected 46 species of 26 families including 9 orders. Among them, the fish of family Gobiidae includes the most number of six species (13.6%). The dominant species was the Argyrosomus argentatus with 53.10%. Total of 17 fish species, including the Cynoglossus joyneri were collected from all of four collecting sites. On the other hand, 13 species including Inimicus japonicus were collected from only one site. Being the wind farm under construction, fish will temporary decrease in this area. But in the long term, we think that Oplegnathus fasciatus, Sebastes shlegelli and others will increase with good inhabited environment provided by the wind farm structures.

Surveys on helminthic fauna of the nutria, Myocastor coypus, have seldom been performed in the Republic of Korea. In the present study, we describe Strongyloides myopotami (Secernentea: Strongyloididae) recovered from the small intestine of feral nutrias. Total 10 adult nutrias were captured in a wetland area in Gimhae-si (City), Gyeongsangnam-do (Province) in April 2013. They were transported to our laboratory, euthanized with ether, and necropsied. About 1,300 nematode specimens were recovered from 10 nutrias, and some of them were morphologically observed by light and scanning electron microscopies. They were 3.7-4.7 ($4.0{\pm}0.36$) mm in length, 0.03-0.04 (0.033) mm in width. The worm dimension and other morphological characters, including prominent lips of the vulva, blunted conical tail, straight type of the ovary, and 8-chambered stoma, were all consistent with S. myopotami. This nematode fauna is reported for the first time in Korea.

This study focuses on the fauna, seasonal prevalence and altitudinal distribution of the flies from March to November, 2008 in Mt. Hallasan, Jejudo Island, Korea. The fauna of flies was 39 species belonging to 5 Families which consist of 12 Calliphoridae, 19 Muscidae, 5 Sarcophagidae, 1 Dryomyzidae 1, Scathophagidae and 1 Anthomyiidae. The total number of flies collected was 21,605 with sex ratio of 57.98% in Mt. Halla. The ratio is higher than that of the residential area and other mountain survey sites. The average number of per trap individuals collected on the trapping day is 267, which is similar with the average of Mts. Jiryong, Juwang, Palgong and Gumo. The five dominant species showed a distinctive seasonal prevalence of 92.6% of the total flies: Chrysomyia pinguis (34.2%), Calliphora lata (25.3%), Hydrotaea dentipes(23.1%), Fannia scalaris (5.1%), and Lucilia caesar (4.9%). The seasonal prevalence of the flies was from the beginning of March to the end of November, and the highest peak time of the whole flies, males and females were different respectively. In the similarity index of the flies collected in different altitude, that of between 1,000 meters and 1,500 meters was the highest among the indices of 500 meters and above 1,000 meters. The index at each altitude was above 80% because of the same area. The diversity index of fly species was between 0.00 and 0.88 through altitudinal traps monthly. The highest index in Trap 1 was 0.88 in October, in Trap 2, 0.82 in July and in Trap 3, 0.63 in July. The diversity above 1,000 meters was most various in July. The five dominant species of C. pinguis, C. lata, H dentipes, F. scalaris, and L. caesar showed distinctive seasonal prevalence, relative abundance and altitudinal distribution respectively.

The fish fauna and disturbance of geographical distributions in the eastern Civilian Control Line of Korea were investigated from May to September 2012. Total 35 species sampled during the period were belonged to 13 families. There were 9 Korean endemic species (25.71%) that distributed in the flows into West and South Sea. Distributions of invasion fishes in the studied streams based on geographical distributions of freshwater fish were total 13 species that classified 1 species, C. cuvieri from foreign country and 12 species from other water systems. Hence there have been anthropogenically introduced from too many years ago. Also groups according to the similarities of each studied stations was divided into 4 groups by similarity 50% because difference in them was considered to effect of domestic invasion species. In conclusion, three streams in the eastern Civilian Control Line of Korea were invaded by many alien fishes. Therefore, we are considered to require precise investigation and monitoring for the preparations to management measure.

The ant fauna in Mt. Gariwangsan was composed of 39 species 24 genera 5 subfamilies. The collected ants in Mt. Gariwangsan were Subfamily Myrmicinae(16 species 11 genera), Subfamily Formicinae(15 species 5 genera), Subfamily Ponerinae(6 species 4 genera), Subfamily Amblyoponinae(1 species 1 genera), and Subfamily Dolichoderrinae(1 species 1 genera). Ant fauna by vegetation in Mt. Gariwangsan, 36 species 23 genera were collected in broadleaf tree areas in which Quercus mongolica, Fraxinus rhynchophylla, Tilia amurensis, and Cornus controversa were dominant species. Paratrechina flavipes and Myrmica kotokui were dominant species. 13 species 12 genera were collected only in broadleaf tree areas. In the coniferous tree areas where Pinus densiflora, Pinus korainensis, and Larix kaempferi were dominant, 24 species 15 genera of ants in total were collected. Pachycondyla chinensis and Paratrechina flavipes were dominant species. 4 species 3 genera were collected only in the coniferous tree areas. Paratrechina flavipes was dominant even in the areas in which Camponotus japonicas and Formica japonica had been assumed to be dominant. Specifically, the higher the land was, the rarer Ponerinae and Dolichoderinae were observed. The common species observed in both areas were 20 species 13 genera. Of these ants, Paratrechina flavipes(Subfamily Formicinae) and Myrmica kotokui(Subfamily Myrmicinae) were distinctive ants. With regard to the current state of colony of these species, Paratrechina flavipes was dominant in lowland areas. Myrmica kotokui, on the other hand, was dominant in highland areas.

In order to investigate the response in fauna and biological communities of terrestrial insects to the vegetation encroachment on the sandbar, species composition, species diversity, functional species traits and community structure of land-dwelling insects sampled by a pit-fall trap were compared at the bare and vegetated sandbar of a typical sand-bed stream, the Naeseong Stream, Korea. Species diversity of the insects was increased but their density was decreased as the riparian vegetation encroached at the sandbar. In particular, indicator species of bare sandbar such as Cicindela laetescripta and Dianemobius csikii, were found at the bar sandbar. The insect communities were clearly classified at the bare and vegetated sandbar according to coverages of riparian plants. The food web of the bare sandbar was composed of detritus - detritivore and scavenger - predator consisted mainly of Coleoptera. On the other hand, the food web of the vegetated sandbar was composed of plants - sucking and chewing herbivore - parasitoid and predator. These results showed that biodiversity of terrestrial insects was increased, food web was changed from grazing to detritus food chain, and insect fauna specific bare sandbar disappeared as the riparian vegetation invaded on the sandbar of a sand-bed stream.

Fish fauna of 13 sites in a main channel and its tributaries of the Taehwa River and 9 Sites of other headwater streams in the Ulsan area (Mt. Gaji) were investigated from February 1999 to October 2000. All sites were the 1st to 5th order streams in the Ulsan area, and 10 sites (45.5%) were intermittent streams. A total of 2,695 flsh specimens were collected and classified into 14 families and 44 species. Cyprinidae accounted for 40.9% (18 species) of the total fish species collected and 68.4% (1,845 ind.) of the total abundance. Subdominant families were Cobitidae (6 species; 78 ind.), Gobiidae (5 species; 240 ind.), and Gasterosteidae (2 species: 128 ind.). Zacco temmincki (RA 23.0%, 14 sites) was the dominant species; subdominant species were Moroco oxycephalus (20.2%, 11 sites), Zacco platypus (8.0%, 10 sites), Mugil cephalus (5.2%, 3 sites). Among the total species, 8 species were endemic species to Korea. The dominant Korean endemic species was Squalidus chankaensis tsuchigae (53.6% of Korean endemic species) and subdominant species were Iksookimia longicorpa (20.5%), and S. japonicus coreanus (6.6%) . Due to the intermittent nature of streams in the Ulsan area, a conservation program of nsh fauna is strongly needed.

This study investigated mammal fauna in the sabbatical area of Mt. Unmun, Kyungsangbuk-do from December, 2007 to September, 2009. A total of 24 species belonging to 11 Families, 6 Orders, were identified in the survey area. Dominant species were as follows: Chinese water deer (Hydropotes inermis), Siberian chipmunk (Tamias sibiricus), Korean mole (Mogera wogura), and East Asian field mouse (Apodemus peninsulae). Especially, four Legal Protection Species specified as National Monument (NM) and Endangered Species (ES) found in this survey were as follows: Flying squirrel (Petromys volans; NM #328 and ES level II), Eurasian otter (Lutra lutra; NM #330 and ES level I), Leopard cat (Prionailurus bengalensis; ES level II) and Marten (Martes flavigula; ES level II). These results on the geographical distribution of various mammal species and Legal Protection Species indicate that this area is a valuable ecosystem for native mammal species. On the other hand, many feral cats were also found and specified as a management species. The results of this study show that further long-term investigation and management plan are needed to protect against harmful species and maintain the native ecosystem of Mt. Unmun.

In order to select an effective and appropriate evaluation method for the marine environmental protection and management, it is necessary to evaluate the present status of environmental conditions and to monitor and regulate the harzadous waste continuously. Among the evaluation methods that use benthic fauna, some graphical methods and biological index methods such as species abundance-biomass (SAB), Rank-frequency diagram (RFD), Abundance-Biomass comparison (ABC), log-normal distribution (LND), and Benthic Pollution Index (BPI) modified by Infaunal Trophic Index were used for the assessments of marine environment in the Inchon coastal area. Even though the graphic methods are convenient for easy glimpse of general trend of environmental condition but because they require sufficient ecological data, those methods do not fit for analysis or comparison of regional and detailed environmental condition. On the other hand, when BPI was applied, it was able to compare the spatial benthic conditions. Through considering the functional aspects of benthic fauna which can not be obtained in the cluster analysis, BPI was made it possible to measure or trace down the source of pollution. In the case of the environmental assessment result analyzed in Inchon coastal area, the north eastern part of Yongjongdo was more influenced by the pollution than the outer area of Inchon. The research indicates that especially Inchon harbor has been greatly affected.
