  • The International Union for Conservation of Nature and Natural Resources (IUCN) considers the western/lowland bongo Tragelaphus eurycerus eurycerus to be a threatened species, and the eastern/mountain bongo Tragelaphus eurycerus isaaci an endangered species[1]. Although extinction is considered by many biologists to be a natural process during evolution, the exponential growth of the human population has drastically and prematurely reduced the numbers and genetic diversity of many species[2]. Species have evolved to adapt to a specific habitat or environment that meet their survival needs. Alteration or destruction of their habitat results in a species becoming incapable of adapting and hence becoming threatened with extinction. A widespread scientific and public consensus has emerged suggesting that governments should assign high priority to the maintenance of biological diversity via habitat preservation and management far species conservation[3]. Unfortunately, the loss of biological diversity far surpasses the available conservation resources and species are lost forever on a daily basis[4]. Notwithstanding the focus on habitat preservation and wildlife management, conservation biologists have also become increasingly interested in using the technologies of reproductive and developmental biology to help manage or rescue endangered species[5].

  • This study analyzed the ecological characteristics of the wetland protection area at tthe Nakdong River through vegetation and biota surveys, which showed that brackish water meets fresh water, a unique ecological environment has been created, biodiversity is high, and diverse habitats are distributed. Eleven plant communities, including four woody communities and seven grass communities, are distributed along the coast, and a total of 514 species, including 11 endangered wildlife species, were identified in terms of species diversity. Among them, the species diversity of the Eulsuk-do area was found to be relatively higher than that of other Barreir Islands areas. The presence of a population of Sterna albifrons on Sinja-do and a population of Eremias argus on Jinwo-do, an area outside the boundaries of the wetland protection area, confirmed the conservation value of the wetlands and the need to expand the boundaries of the wetland protection area. It is judged that this information can be used as basic information for a systematic conservation and management plan for the wetland protection area at the Nakdong River Estuary and as basic data to support the establishment of a policy.

  • 최근 멧돼지의 개체수 및 농작물 피해 증가로 인하여 사회적 문제를 야기 시키고 있다. 국내 멧돼지에 대한 연구는 미미하여 향후 효과적인 멧돼지 관리를 위해서는 종에 대한 생태적 연구가 필요하다. 본 연구는 2012년 5월부터 12월까지 경남 거창군 일대에서 유해야생동물 포획을 통해 수집된 멧돼지 위 내용물(n=79) 분석을 통하여 식이습성 구명 및 선호 농작물을 파학하기 위해 수행되었다. 연구 결과 멧돼지는 주로 식물성 먹이를 섭식하며, 계절별로 유의한 차이를 나타냈다. 식물성 먹이는 잎-줄기가 83.5%로 가장 높은 출현율 보였으며, 농작물을 포함한 식물성 먹이는 건중량의 93.5%을 차지하였다. 무척추동물의 발견 빈도는 높았으나 빠르게 소화되는 특성으로 인하여 건중량은 낮게 나타났다. 식이농작물로는 밤, 벼, 사과 등이 선호하는 농작물로 나타났다. 수확기 농작물은 멧돼지가 야생 먹이보다 선호하여 의도적으로 섭식하는 것으로 판단된다. 지렁이는 총 수집된 위에서 50%의 출현율을 보였으며, 섭식 마릿수는 여름에 가장 높고, 겨울에 낮은 것으로 나타났다. 멧돼지는 전형적인 잡식성의 성향을 보이며, 시기에 따라 섭식하는 식이물이 다른 것으로 나타났다. 향후 멧돼지에 의한 농작물 피해를 줄이기 위해서는 밤나무림에 인접한 논과 사과 과수원의 우선적인 피해방지가 필요할 것으로 판단된다.

  • 지난 4 년간에 걸친 순환수렵장(循環狩獵場) 운영상황(運營狀況)과 문헌조사(文獻調査) 및 수렵인에 대한 설문조사(設問調査) 결과(結果)를 토대로 다음과 같은 문제점(問題點) 내지 특성(特性)을 도출하였다. 1) 수렵인(狩獵人)들은 현행의 순환수렵제도의 불편함과 과대한 이용비용(利用費用)의 완화를 바란다. 또 수렵자(狩獵者)는 년평균 2,000 여명 밖에 되지 않지만 銃器所持者(총기소지자)가 200,000 명이 넘는 사실을 감안할 때 수렵여건이 좋아진다면 폭발적인 증가를 보일 것이 예상된다. 2) 수렵인(狩獵人)들의 수렵(狩獵)과 야생조수(野生鳥獸)에 대한 지식수준(知識水準)이 매우 낮고, 수렵윤리관(狩獵倫理觀) 확립이 미약하다. 3) 수렵강습회(狩獵講習會)의 시간(時間) 배당(配當)이 너무 수렵(狩獵)을 위한 수사(獵師)의 자질(資質) 향상(向上)시키기에는 충분치 못하다. 4) 포획두수(捕獲頭數)에 비추어 본 야생조수(野生鳥獸)의 밀도(密度)는 아직 적정서식밀도(適正棲息密度)에 미달이라고 보여진다. 5) 수렵활동(狩繼活動)에 의한 관광경제적(觀光經濟的) 면(面)의 기여는 아직 미약하다. 6) 야생동물(野生動物)의 실태조사(實態調査)와 수렵(狩獵)에 관한 제도적(制度的), 법률적(法律的)인 연구(硏究)가 요망(要望)되며 수렵(狩獵)과 농(慶) 임업(林業)과의 이해(利害)를 조정(調整)하는 작업(作業)이 필요하다. 이상(以上)과 같은 문제점들을 해결하고, 또 장기적인 안목에서 건전한 수렵을 육성시키기 위해서 다음의 두 가지 제도를 제안(提案)하는 바이다. 1) 수렵면허시험제도(狩獵免許試驗制度)의 신설(新設) 수렵인의 수렵과 야생동물에 대한 지식이 너무 부족하므로 철저한 시험제도를 거쳐 선발함이 바람직하다. 2) Revier system 엽구제도(獵區制度)의 도입(導入) 본 제도의 근본개념은 야생동물의 수렵권(狩獵權)이 토지소유주(土地所有主)에 귀속되어 있다는 것에 근거하여, 사적(私的) 소유개념(所有槪念)으로부터 보호(保護)와 배식(培植)에 강한 동기(動機)를 부여할 수 있다.

  • The function of urban parks as wildlife habitats is becoming increasingly important. The urban park serves as a key area for preserving urban biodiversity. The purpose of this study is to estimate the bird species diversity in 30 parks in Cheonan city and quantitatively analyze the influence of vegetation, park structure and landscape connectivity index. As the results, a total of 27 birds species and 1,509 individuals were found at the sites and the largest number of birds were found in the Cheongsa park with 17 species. The optimal regression model was selected as the explanatory variables for the logged park area (LPA), the tree cover ratio (Co_T) and the patch betweenness centrality (PB). LPA and Co_T mean the internal characteristics of the park, and PB was the external environmental variable meaning landscape connectivity. LPA was the most important factor (73.3%) as bird habitat, and the PB could be interpreted as a factor that should be considered as important (26.7%). It will be possible to consider these environmental variables in the park and green area construction and management.

  • The present study is an attempt to give an account of the inventory of plant species, phytosociological characteristics of vegetation and pedological characteristics of Rambi Beat Forest under Senchal East Forest Zone, Darjeeling, West Bengal, India. Its plant community were analyzed quantitatively and synthetically. The results reflect dominancy of dicotyledons over monocotyledons in the four studied sites The plant community comprising of 50 plant species belonging to 40 genera of 27 families. Ramhi beat reflected higher diversity of species. Maximum IVI value was recorded by Viola surpense (47.17) in Rambhi forest beat. The Berger parker index and evenness index were found to be highest for Viola surpense, Fragaria nubicola, Pilea umbrosa in Rambhi beat. The soil characteristics of the different pedons revealed alkaline nature of soil in Rambhi beat. Higher levels of soil organic carbon content reflect higher fertility of the soil of Rambhi beat. The response towards soil available nitrogen and phosphate were different among the ten pedons of Rambhi beat. Therefore, proper management and conservative measures needs to be implemented for conservation of bioresources in Senchel wildlife Sanctuary of West Bengal, India.

  • To provide basic information for wildlife management, we investigated the distribution and ecology of wild mice in Mt. Keumwon recreational forests. The trapped wild mice were a total of 4 species such as Eothenomys regulus, Apodemus speciosus peninsulae, Apodemus agarius, and Crocidura suaveolens. A total of 79 individuals from four species were trapped. Number of Eothenomys regulus was the highest as 41 individuals followed by Apodemus speciosus peninsulae of 31 individuals, Apodemus agarius of 4 individuals, and Crocidura suaveolens of 4 individuals. Depending on forest type, 51 individuals were captured in broad-leaved forests, whereas 28 individuals were captured in coniferous forests. Average weight of the trapped Eothenomys regulus, Apodemus speciosus peninsulae, Apodemus agarius, and Crocidura suaveolens was 37.13 g, 36.29 g, 31.25 g, and 15 g, respectively. Among the trapped wild mice, vole which has the largest head and ears were Eothenomys regulus and vole which has the longest tail was Apodemus speciosus peninsulae and Apodemus agarius (p<0.5). This study might be valuable to control and predict some damages related to wild mice in Mt. Keumwon for protecting forest trees.

  • Present green space planning of Korea pay little attention to biodiversity conservation in urban areas. The quality of urban wildlife habitat has been deteriorated severely due to fragmentation and isolation of urban open spaces. The application of ecological corridors to urban green space planning and management can greatly enhance the bird habitat of Seoul. The objectives of this study were to evaluate bird habitat potential of existing urban parks of Seoul, and to investigate methods to develop ecological corridors for wild birds. This study consists of three parts. The first part is to construct bird species/habitat relationship model. The second part is to evaluate 207 urban parks of Seoul with the model. Based on the relative potential for bird habitat, urban parks of Seoul can be classified into cores, nodes, and points of the network. Outcomes of this part can also be used to enhance the quality of bird habitats by identifying limits or weakness of existing green spaces for bird habitat. The final part is to develop three green network plans; north-south network, the Han river network, and a district network for Kangnam-Gu.

  • At a turn of the third millennium the world storms and quickly changes. It became difficult to expect what expects us tomorrow. The most important are questions of recovery from the crisis and rescue of mankind from forthcoming global changes: warming of climate, water and food problems, social, economic and political conflicts that are shaking the world and other various cataclysms, accidents, negative processes. It puts before mankind the problem which never solved by our civilization. All this is caused by ignoring of objective economic laws, laws of wildlife and also by violation of cyclic development management's laws. In article the concept of strategy of mankind's survival in XXI and next centuries, the principles of creation of planetary house of universal civilization for post-industrial world based on spirituality scientific and technological revolutions, ecology, space exploration, economy and world safety are considered. Introduction of uniform universal measurement of currency for the whole world in the form of "power" is offered. Important aspect of a research is theoretical postulate on integrated innovative society. The author puts forward a new paradigm of government on a basis of 5 spirals. The basic model of forced development of small and medium business, including 9 projects, is developed.
