  • The purpose of this study is to build Island biogeography in the basic concept of landscape ecology in South Korea by draw relationship between the species side of quantitative habitats and forest area surveyed in the national database based on investigation of the 2nd natural environment. In addition, try to present criterion of habitats character category after understanding habitats character of emergence area side of quality habitats based on the type of formatting. Species and forest area relationship analyzed using correlation analysis and simple regression analysis. Also habitat character limited composition ratio of neighboring land cover and analyzed using hierarchical cluster analysis to classify type of habitat. As a result, we found that forest area is correlated with number of species, forests which is bigger than 100ha are more important of increase in species' population. And according to land cover composition ratio, bird's classified types of forest inner species, forest edge species, forest outer species and mammal's classified types of forest inner species, forest general species, forest edge species. We suggest that study of species-forest area relationship and emergence habitat character be used as some management plans of species' conservation, protection and restoration.

  • 조류인플루엔자는 닭이나 오리와 같은 가금류 또는 야생조류에서 생기는 바이러스의 하나로, 농장에 큰 피해를 줄 뿐 아니라 인체에 치명적 영향을 줄 수 있다. 특히 조류인플루엔자의 주요 발생원이 철새로 추정되는 상황에서 이에 대한 예찰활동은 중요하다. 철새가 텃새에게 조류인플루엔자를 전염시키면 이로 인해 국내 가금류에게 2차 전염을 유발할 확률이 높기 때문이다. 따라서 본 연구는 겨울철 국내에 유입되는 철새의 AI 전파 현상을 시스템다이나믹스를 이용하여 모델링함으로써 예찰활동에 대한 시사점을 도출하였다.

  • Reintroduction programs have been promoted across the world to recover and rehabilitate endangered birds through ex situ captive breeding and releasing to the nature. The ultimate aims of these reintroduction programs are recovery of sustainable populations in natural habitats. To ensure the success of the reintroduction programs, it is necessary to examine the followings in order to increase the success rate of releasing along with the development of captive breeding techniques: 1) Adequate habitat provision, 2) adaptability of captive-bred individuals, 3) survivability of released individuals, and 4) social interest and will. Before releasing captive-bred individuals, it should be reviewed whether there are habitats in which the limiting factor is removed, and assessed their long-term safety. The quantity and quality of the released individuals must be considered to increase the chances for mate selection, maintain genetic diversity, and acquire the ability to adapt to the wild. The release method must be decided in consideration of characteristics of the target habitats and individuals, and rational means such as careful observation, evaluation, and feedback must be provided throughout the release process. For the long-term success of recovery projects, social awareness, sustainable support, and related experts are needed. Satisfying these criteria can help to increase the success rates of reintroduction programs. For the bird reintroduction program in the future, the feasibility of the methods and procedures must be closely reviewed before starting.

  • 도시에서 사람과 야생조류는 함께 살아가고 있으나, 도시화가 가져온 생태계 파편화로 조류의 서식과 이동에 위협 영향을 미친다. 본 연구에서는 수원시의 야생조류 사체 위치 데이터를 토대로 조류에게 취약한 공간, 위협요인을 확인하고자, 사체 확인 지점과 반경 500m 이내의 공간적 분포 특성을 살펴보았다. 연구결과, 사체 확인 지점은 NDVI 0.3, NDBI -0.05, NDWI -0.16의 특성을 보였다. 반경 500m 이내에는 NDVI 0.34, NDBI -0.01, NDWI -0.18, 건물 높이 13.8m, 방음벽 길이 227.3m로 확인되었다. 토지피복유형은 초지, 시가화건조지역, 나지가 높은 비율로 나타났다. 특히, 산림, 저수지 등과 인접한 아파트의 녹지, 골프장 등이 섞여있는 시가화지역의 가장자리가 위협적인 공간으로 도출되었다. 도시에서 조류와 함께 살아가기 위해서는 환경영향평가 단계에서부터 수직적 공간 변화에 따른 영향이 검토되어야 하며, 이에 앞서 도시의 수직 구조물에 대한 공간 자료 구축과 현실화가 필요하다. 또한, 자연에서 도시로 변화될 수밖에 없는 공간은 야생동물이 안전하게 회피, 적응할 수 있는 시공간적 측면이 고려된 사전예방적 관리방안이 함께 마련되어야 할 것이다.

  • This study aims at analyzing relationships between land use and habitat types of winter wildbirds to provide basic understanding of ecosystem for preservation and restoration of urban ecosystem in the future. The research area is Hanam City. Researches on land use types showed Hanam City had 79.1% of greenspace and openspace, but intensive urban development has been taking place in greenspace that is adjacent to urban districts. This has brought the problems of lack of greenspace in urban districts and damages to cultivated areas and grassland. A total of 61 and 8,642 populations of winter wildbird species were observed in research areas. Paradoxornis webbiann(16.91), Passer montanus(11.93), Pica pica(6.88) were dominant species. When they were divided according to habitat types, 20 species of interior species, 8 species of interior-edge generalist species, 12 species of edge species and 3 species of urban species were observed. When which land use type was mostly served as wildbirds habitats was examined, urban species(3 species and 290 populations) was a dominant species in urban districts while in greenspace and openspaece, water species(19species and 3,075 populations) including winter migratory birds was. Among greenspace and openspaece, edge species was dominant in forest while urban species was a dominant species in cultivated areas. This shows there is a need to improve diversity of wildbirds through restoration of cultivated areas in the central part of Hanam City.

  • Analysing companion species from unrelated taxa concentrated so far mainly on identifying biosurrogacy in terms of conservation biology. No study has investigated companion bird and plant species to predict breeding and migrant habitats of a bird genus. In this study we recorded and analysed companion bird and plant species of the breeding bird Cyprus Wheatear Oenanthe cypriaca and four migranting Oenanthe species on Cyprus. We found characteristic companion species in Cyprus Wheatear's, Wheatear migrant's and in control habitats where no Wheatears were present. We show that plant and bird companion species can be used as discriminating factors to predict breeding and migrant habitats of the genus Oenanthe on Cyprus. Furthermore, habitat preferences of Cyprus Wheatear's companion species indicate bushy and vegetation rich habitats avoiding woodland on the one hand and managed farmland on the other hand. In comparison, migrant Wheatear and control habitats were characterised by companion species pointing to a high openness. These results support former habitat descriptions of Cyprus Wheatear and migrant Wheatears. In more general, this study shows that companion species from unrelated taxa can be used to predict breeding and migrant habitats of a bird genus.

  • 홍천강 유역은 우리나라 대표적인 청정지역으로 수생태계의 대표적인 수달이 서식하는 지역이다. 이들 지역에서 서식하는 수달의 서식지분석을 위해 식이물 연구가 수행되었다. 총 478개의 흔적 및 배설물이 사용되었으며, 수달의 식이물 분석 결과 80.5%가 어류인 것으로 조사되었다. 어류 중 이 지역에서 가장 우점하는 갈겨니(Zacco temminckii)의 식이물이 확인되었으며, 양서류 및 조류가 섭식된 것으로 나타났다. 계절적으로는 여름철 식이물의 빈도가 가장 높게 나타났으며 먹이자원이 여름철에 풍부한 것으로 보인다. 군업천과 내촌천의 식이물 구성 및 빈도는 크게 다르지 않았다. 현재 이 지역은 홍천-양양간 고속도로 건설이 진행되는 지역으로 수달 식이물 분석을 통한 인공서식지, 관리방안 도출 등이 수행되어야 한다.

  • Urban development typically results in many species being confined to small, isolated and degraded habitat fragments. Fragment size and isolation underpin many studies of modified landscape to prevent biodiversity loss. However, habitat characteristics such as vegetation structure and edge effects are less frequently incorporated in planning. The relative influence of biogeographic (e.g. size, isolation) and vegetation parameters on assemblages is poorly understood, but critical for conservation management. In this study, the relative importance of biogeographic and vegetation parameters in explaining the diversity of forest-interior dwelling birds in forest fragments in Chungcheong Province Area. Fragment size and vegetation characteristics were consistently important predictors of bird diversity. Forestinterior bird richness was influenced by fragment size (0.437), wood age (0.332), wood diameter (0.068), and patch shape (-0.079). To preserve bird diversity of Chungcheong Province Area, it is important to consider differing responses of bird diversity to landscape change, move beyond a focus primarily on spatial attributes (size, isolation) to recognize that landscape change also has profound effects on habitat composition and quality. The result is very useful for long-term aspect of biodiversity conservation plan in regional scale.
