Yangjae stream was divided with Seoul and Gwacheon reach. Seoul reach was ecologically restored; however, Gwacheon reach was not. Similarity index of the bird communities between the two areas was relatively high, 79.9%. The dominant species in Seoul reach were Passer montanus, Pica pica, Paradoxornis webbianus and Anas crecca. The dominant species in Gwacheon reach were Passer montanus, Pica pica, Paradoxornis webbianus and Streptopelia orientalis. The different species was Anas crecca in Seoul and Streptopelia orientalis in Gwacheon. An eco-park was constructed along the stream of Seoul reach since 1996 but was not in Gwacheon reach; the number of species has increased in Seoul area($r^2$=0.846, p<0.01), but Gwacheon was not change($r^2$=0.023, p>0.05) since 1996. The number of individuals, however, was almost constant in both reaches(Seoul : $r^2$=0.211, p>0.05, Gwacheon : $r^2$=0.032, p>0.05). In Seoul reach, the ecological restoration of stream was helpful to increase bird diversity. The number of waterbirds such as herons, plovers, sandpipers and wagtails was higher in Gwacheon reach than in Seoul reach, but the number of ducks and songbirds was higher in Seoul reach than in Gwacheon reach. We suggest that the ecological restoration in Seoul area might have negative effects on sandpipers, plovers and wagtails inhabiting on the flood plain in stream, but positive effects on other species such as herons, ducks and songbirds. Especially, the increasing number of ducks was attributed to an artificial pond in flood plain. The difference in the number of Streptopelia orientalis between both reaches was owing to the habitat differences such as forest trees playing a role as patch in high revetment. From the present investigation, it could be concluded that the ecological restoration of the local stream must be carried out with consideration of water channels, sand banks and water front in addition to the high revetment for birds to attract diverse bird communities.

댐의 습지로서의 기능을 평가하기 위해 댐도 하나의 습지로 정의하고, HGM 습지 평가 방법에 따라 보령댐을 우포늪의 습지 기능을 비교 평가하였다. 보령댐의 습지로서 수문학적 기능은 단기적이고 작은 흐름들에 대해서는 취약성을 가지지만, 반면 장기적이고 큰 흐름들에 대해서는 강점을 가진다. 생지화학적 기능은 우포의 약 50%정도를 수행하는 것으로 나타났다. 식물 서식처로서의 기능도 식물 군집의 유지 측면에서 매우 우수한 기능을 하는 것으로 나타났다. 동물 서식처로서의 기능은 우포늪에 준하는 기능을 수행하였다. 다만 조류의 서식처로서의 기능이 다소 부족하였다. 이 연구를 통해 보령댐의 장점과 단점을 명확히 하여 장점을 살리고 단점을 보강 할 근거를 마련하고자 한다.

This is a case report of a northern goshawk (Accipiter gentilis), admitted to the wildlife rescue center with right coracoid and scapular fracture which received conservative treatment and was soft-released successfully. At the admission, the goshawk had callus formed on the fractured bones, scars on eyebrows and severely damaged tail feathers with inability to fly. Cage rest was indicated to prevent further occurrence of fracture and to promote reunion of the fracture surface. The bird went through a rehabilitation process with appropriate physical training in flying cage to recover its fitness and flying ability. Complete molting of flight feathers with damaged rectrices was achieved during the rehabilitation period and its flight ability was recovered favorably. It was released into a proper habitat for northern goshawks, but the bird was found near the aviary where its last phase of rehabilitation was performed. A soft-release program was applied and finally the bird returned to near the first rescue location 235 km away from the release site.

매(Falco peregrinus)는 천연기념물 323호이며 멸종위기종으로 등재되어 있다. 본 연구는 한강의 장항습지에 서식하는 매의 멸종확률을 개체군변이분석을 통하여 시도하고자 한다. 장항습지는 개체군이 1999-2005년 동안 모니터링되었으며 평균 10.8 개체가 서식하는 것으로 조사되었으며, 개체군을 이용하여 향후 5년간(2015-2020) 변이분석을 실시하였다. 초기개체군을 이용하여 기간 동안 20%의 멸종확률이 예측되었으며, 이 확률은 지역의 수질오염과 서식지 손실을 고려하면 적은 것으로 나타났다. PVA는 개체군이 적고 다른 정보가 부족한 종에 대해 실시한다. 또한 매의 개체군은 댐의 보 및 콘크리트 제방 등을 고려하면 멸종의 확률이 증가될 것으로 사료된다. 장기적인 생활사 등을 고려한 연구가 필요하다.

With recent emphasis on the creation of environment-friendly new towns, introduction of ecological facilities for habitation and migration of wild animal's species is requested when developing new towns. In order to introduce such facilities, building an eco-network within the site based on the connectivity of the source area and habitats is essential in new town development. Therefore, this study mainly aimed at selecting species targeted for building an eco-network in Pangyo new town, which is intended to be an environment-friendly city. Therefore, criteria for selecting target species were generated. Then, species observed within the site through field surveys and literature review was evaluated based on the selection criteria and items. By totaling the score, a list of appropriate targeted species was finalized. Among species surveyed and observed in the site, appropriate target species that may be selected for Pangyo new town's eco-network include Falco tinnunculus interstinctus, Accipiter soloensis, Picus canus, Paradoxornis webbiana, Parus palustris, Parus ater, Parus major and Passer montanus Egretta in birds, Asiatic chipmunk, Nyctereutes procyonoides in mammals. For Pangyo new town, it is essential to create living environment and build a network for major wild animal species within the site based on target species. This will play a crucial role in building a reasonable ecological network enabling harmonious co-existence between mankind and nature. In order to build an ecological network successfully, follow-up studies need to be conducted on restoration technology and methods required for creating habitats appropriate to target species.

This study examined the habitat status of wild birds at closed-trails and the control group of opened-trails in the national park of the Baekdudaegan mountains. After evaluating each area based on this, it's aimed at being utilized as basic data for future national park management and opening of trails. Upon field investigations and analyzing existing literary materials, it was found that there were a total of 76 bird species living around the trails. Among them, it was confirmed that 60 species can breeding and 10 species are protected by law. Upon assessing the scores of each area according to the evaluation standards of this study, Area I had 7 scores, area II had 13 scores, area III had 5 scores, and area IV had 16 scores, showing that the control group open-trail area IV between Jeongryeongchi and Seongsamjae had the highest score, and that area III of Wolyeongdae~Chotdaebong~Daeyasan~Miljae~Wolyeongdae had the lowest score. Evaluation of closed-trail according to wild bird species (Avifauna) was attempted in this study, but there were more bird species living in open-trails, while also having higher evaluation scores. Therefore, if opening trail is needed in the future due to excessive desires of visitors or inevitable social demands, it is judged that various environmental factors including mammals highly affected by people should be evaluated to open up the sector with the lowest score. Also, it is judged that through methods such as reservation systems, the number of visitors should be controlled or night-time hikes should be prohibited so that nocturnal wildlife can freely use the trails.

The Korea Water Resources Corporation(KOWACO) proposed bidding for an alternative design for Hwabuk Multi-purpose Dam in March of 2004. The site is located in Hakseong-ri, Goro-myeon, Gunwi-gun, Gyeongsangbuk-do and has adrainage area of $87.52km^2$. The purpose of this project is to establish an environmentally friendly plan for minimizing the damage that was caused by the construction of the Hwabuk Multi-purpose Dam. The design principle of KOWACO was the restoration of the natural environment, a harmonious landscape, and the creation of a space of regional and local culture. The basic concept of this project involves an ecological-restoration axis and a functional-connection axis. The site is divided into four spaces: (1) the space of memory and symbol, (2) the space of nature and ecology, (3) the space of regional and local culture, and (4) the space of the regional economy. There are four sub-spaces in the space of memory and symbol: the track forest, the time forest, the memory room, and the sun plaza. There are three sub-spaces in the space of nature and ecology: the habitat of aquatic birds, the wind forest, and the eco-corridor. There are five themed parks in the space of regional and local culture: the culture and relic room, the wildflower garden, the ecological pond, the insect observation park, and the pyogo maze. There are three areas in the space of the regional economy: the forest pension, the waterside pension, and the community center, as Dungdungi village was reorganized to serve as a lodging complex. These themed parks, working together, can offer an effective space for nature, culture, rest, and experience.

The Chinese crested tern (Thalasseus bersteini) is one of the most globally endangered species, listed as "Critically Endangered (CE)" on the IUCN Red List, with only approximately 30-49 individuals surviving in the wild. Chinese crested terns were discovered to breed in South Korea for the first time in 2016 while conducting a census on uninhabited islands. The Ministry of Environment has declared the breeding habitat of the Chinese crested terns as "Specified Island" to protect this CE species. However, brown rats (Rattus norvegicus) inhabiting the breeding grounds of the Chinese crested terns and Black-tailed gulls may potentially pose a threat to the breeding of these avian species. Therefore, we conducted a study on the feeding behavior of brown rats involving stable isotope analysis to determine their food sources. Fecal analysis showed that brown rats mainly fed on plants, whereas they scarcely fed on animals, such as insects. In addition, the stable isotope analysis showed that the δ¹³C values of brown rats, insects, and Indian goosegrasses were approximately -16 to -11‰, whereas the δ¹³C value of Chinese crested terns that obtained their food from the marine ecosystem was approximately -22 to -18‰. Hence, we conclude that the source of carbon for brown rats on this island is the terrestrial ecosystem. We ruled out the possibility of any direct prey-predator interaction between the brown rat and the Chinese crested tern or Black-tailed gull.

Blastocystis is a genus of unicellular heterokont parasites belonging to a group of organisms known as Stramenopiles, which includes algae, diatoms, and water molds. Blastocystis includes several species that habitat in the gastrointestinal tracts of organisms as diverse as humans, farm animals, birds, rodents, reptiles, amphibians, fish, and cockroaches. It is important to public health and distributed globally, but its prevalence in dogs in Korea has not been reported to date. Here, we collected 787 canine fecal samples and assessed Blastocystis infection by age, sex, region, season, and diarrhea symptoms. We determined Blastocystis subtypes using phylogenetic analyses based on 18S rRNA gene sequences. We identified, 10 Blastocystis positive samples (1.3%). A higher proportion of infected dogs was asymptomatic; however, infection rates did not significantly differ according to region, age, sex, and season. Phylogenetic analysis showed that the Blastocystis sp. identified belonged to 4 subtypes (STs), ST1, ST5, ST10, and ST14, thus revealed the genetic diversity of Blastocystis sp. in dogs Korean. This is first report on the presence of Blastocystis sp. in dogs Korean. This study revealed a lower infection rate than expected and differed from previous studies in STs. Further studies are warranted to observe the national infection status of Blastocystis in dogs and the genetic characteristics of this genus.

최근 외래어종의 유입은 하천 내 어류 관리에 문제가 되고 있다. 최근 하천환경에 대한 인식이 높아지면서 하천변을 환경적이 기능을 갖도록 정비하는 사례가 많아지고 있다. 대저 생태공원은 4대강 사업에서 비닐하우스 등 관리하기 어려운 하천변 시설을 철거하고 조성된 지역이다. 조성된 대저생태공원은 철새도래지로의 의미와 수중생태계의 다양성을 제공하기 위한 하천공간으로의 환경적 요소를 고려한 정비로 설명할 수 있다. 이러한 자연친화적인 하천사업에도 불구하고, 외래어종은 환경공간을 파괴하고 하천 생태계에 악영향을 미칠 수 가능성을 가지고 있다. 본 연구는 낙동간 본류와 더블어 생태공원에서도 어류상 조사 및 우세종/외래어종 점유율 분석을 수행한 것이다. 대저생태공원은 정체지역으로 낙동강 본류와 수리적 특성이 다르므로 획득된 자료를 통해 생태공원의 외래어종 관리방안을 마련하는 것이 필요하다.
