Currently, biodiversity conservation is regarded as one of the most important environmental issues in the 21st century. However, The educational approaches on biodiversity conservation is not actively developed. This study was conducted to develop the educational program on biodiversity conservation related with endangered species conservation for improving elementary and middle school girl students' knowledge on biodiversity, inspiring the value and importance of biodiversity, and improving the attitude toward the conservation of biodiversity. Because the biodiversity loss of wetlands such as rice-fields, rivers, marshes has made the breeding population of Oriental White Stork(Ciconia boyciana) endangered in Korea, this subject was very effective for students to learn the cause and effect of biodiversity loss realistically. The education program was conducted to 68 local elementary and middle girl students from 2007 to 2009 and consists of three main activities such as feeding on storks in captivity, sampling living organisms in rice-fields, and designing the future stork living village. The results didn't show a positive effect on improving the knowledge on the biodiversity, but a positive effect on improving the attitude toward the conservation of biodiversity. And the number of taxa that students noticed in rice-fields has increased significantly. In conclusion, this educational program promoted students to concern about and take up a positive attitude on the biodiversity conservation issue.

Biodiversity, referring to the variety and abundance of species, their genetic composition, and the communities, ecosystem, and landscapes, is essential to maintain healthy and productive forests, and to provide useful hedge against the future uncertainties in conditions of the environment and natural resources. To realize the long-term sustainability for forest production of goods and services is dependent upon maintaining and enhancing the biodiversity in the forest ecosystem. Because we can not always recognized which portion of biodiversity is essential to maintain the stability and sustainability of the natural system, conserving biodiversity is even unconditionally important. Even though the activities of forest resource management may have a variety of negative impacts on biodiversity by modification of the natural ecosystem into economically effective artificial ecosystem, forest professionals have been developing intelligent scheme to coexist management and conservation. However, conservation of biodiversity must be a complex problem encircled by ecological, economical, and social considerations. There seems to be no such a simple and easy solution. Strategies for ecologically deliberated forest resource management, which could play an important role to conserve biodiversity, were discussed.

환경평가에 생물다양성 손실을 최소화하기 위한 가이드라인을 적용하고자 하는 노력이 외국에서 진행 중이지만 국내에서는 고려의 대상이 거의 되지 못하고 있다. 이러한 상황이 지속되면 우리나라의 생물다양성이 급격히 감소할 것이다. 따라서 우리도 생물다양성의 손실을 최소화하도록 지침을 준비하는 것이 시급한 실정이다. 본 연구에서는 현재 환경영향평가 시스템의 잠정적인 문제를 평가하고, 현재 시스템에 생물다양성/생태계 항목을 어떻게 도입할 것인가에 대한 정보를 제공하기 위해 고속도로 건설사업에 대한 32개의 환경영향평가서를 분석하였다. 평가서의 분석에서 서식지 및 생물다양성을 다루는 경우는 드물었고 생물다양성 이슈들의 평가가 거의 없는 것으로 나타났다. 따라서 현재 시스템의 현황조사와 영향예측 및 상응하는 저감대책에 생물다양성 이슈들을 고려하도록 개선할 필요가 있다.

Natural ecosystem is an essential part to connect with the plan for biodiversity conservation in response strategy against climate change. For connecting biodiversity conservation with climate change strategy, Europe, America, Japan, and China are making an effort to discuss protection necessity through national biodiversity valuation but precedent studies lack in Korea. In this study, we made biodiversity maps representing biodiversity distribution range using species richness in National Forest Inventory (NFI) and Forest Description data. Using regression tree algorithm, we divided various classes by decision rule and constructed biodiversity maps, which has accuracy level of over 70%. Therefore, the biodiversity maps produced in this study can be used as base information for decision makers and plan for conservation of biodiversity & continuous management. Furthermore, this study can suggest a strategy for increasing efficiency of forest information in national level.

Dictyopteris divaricata, a type of marine brown algae, has been studied for its various biological properties, including anti-inflammatory, antidiabetic, and whitening effects. However, its potential antiobesity effects have not been extensively explored. This study aimed to examine the impact of D. divaricata ethanol extract (DDE) on adipocyte differentiation and adipogenesis using 3T3-L1 preadipocytes. Our results showed that when 3T3-L1 preadipocytes were treated with noncytotoxic concentrations of DDE there was a concentration-dependent decrease in fat accumulation rate and triglycerid production compared with the control. Furthermore, DDE significantly reduced the expression of transcription factors (PPARγ, C/EBPα, and SREBP-1) and fatty acid transport protein (FABP4), which are crucial for 3T3-L1 preadipocyte differentiation. These findings suggest that DDE may exhibit antiobesity effects by suppressing the expression of lipogenic transcription factors and fatty acid transport proteins. Therefore, DDE holds potential as a therapeutic agent for obesity.

세계적으로 인간의 활동에 따른 서식지 훼손 및 기후 변화에 의해 생물다양성이 감소하고 있다. 이에 따라, 생물 다양성의 감소를 막기 위해서 국제사회는 생물다양성 협약과 같은 협력 체제를 마련하는 등의 노력을 하고 있다. 지금까지 우리나라의 생물다양성 전략 및 계획은 주로 정부의 주도하에 정책적으로 진행되었으나, 국가에 의한 생물다양성전략은 보수적이며, 실행 계획이 구체적이지 않다는 단점을 가진다. 따라서 지자체 생물자원을 관리하기 위한 방법으로 지자체 생물다양성 관리전략을 제안하였다. 지자체 생물다양성 관리전략 수립을 위한 전략계획 및 세부계획을 제시하기 위해 생물다양성 협약, '2011~2020 생물다양성 전략계획', 우리나라 생물다양성 전략 및 이행계획과 해외 지자체 생물다양성 관리전략 우수 사례를 분석하였다. 결과적으로, 각각의 사례에서 중요하게 제시하고 있는 개별 생물종의 조사 및 보호, 보전지역의 지정 및 모니터링, 통합적 생태네트워크 관리, 생물다양성 전문기관의 설립과 전문가 양성방안, 지역의 인적 네트워크와 전통지식 활성화 방안, 생물산업 육성방안의 추진전략을 도출할 수 있었다. 이러한 지자체 생물다양성 관리전략의 이행은 '2011~2020 생물다양성 전략계획'의 목표를 달성하여 생물다양성을 보전하고 증진하는 데 큰 도움이 될 것이다.

Recent conditions in North Sulawesi Province (NSP) have become favorable for the development of tourism. In this paper, we present the recent status of biodiversity and tourism in NSP as a basic consideration towards integrative biodiversity conservation strategy. Overall, biological accounts suggest that NSP is important for the world biodiversity conservation program. NSP's biodiversity makes the area a major nature-based tourism (ecotourism) site in the world. Development of diverse tourism programs in NSP has provided new opportunities for balancing development and conservation of regional ecosystems. However, the excessive tourism growth in some particular areas in NSP has been identified as the primary factor of environmental degradation. Nowadays, biodiversity of North Sulawesi regions are suffering from the number of tourist impacts and facilities. Based on those conditions, tourism planning and development in NSP is needed to formulate a proper strategy to protect the ecosystem and biodiversity from degradation and extinction. This will be a new challenge of sustainable island tourism development and biodiversity conservation in NSP.

The Tian Shan mountain system is one of the large mountain ranges located in Central Asia. This region is globally recognized as mountain ranges, offering inestimable wealth in fauna and flora with significant biodiversity values. We surveyed macrofungal diversity of Tian Shan in Kyrgyzstan from 2016 to 2018. A collection of macrofungi was made, and these were subjected to sequence comparisons and phylogenetic analysis to ensure the identity of the collected macrofungi. Of those collected, 95 out of 100 specimens were successfully sequenced and compared with those of other related species retrieved from GenBank. The sequenced specimens were classified into 2 phyla, 8 orders, 24 families, 47 genera, and 57 species, based on current taxonomic concepts (combining morphology and phylogeny). To the best of our knowledge, this study provides the first well-documented checklist and phylogenetic analysis of macrofungi recovered from the Tian Shan mountains in Kyrgyzstan.

As United Nation (UN) declared 2010 to be the International Year of Biodiversity, the biodiversity issue has gained much attention since the issue of climate changes. Also, related researches for protecting and conserving the biodiversity are accompanied in the world. In this study, National Ecology Information is obtained from Ministry of Environment and Korea Forest Service and is utilized to valuate biodiversity and ecosystem services in Pyeongchang, Kangwon-do in Korea. For this, they are categorized into direct- or indirect-use value and nonuse value. Research results show that the biodiversity and ecosystem services in Pyeongchang are assessed as 2 trillion and 460 billion won. From this research, we evaluate the economic value of biodiversity and ecosystem services, and also suggest the possibility to utilize them as basic information for a decision making to establish the biodiversity protection plan.
