  • The Gold-spotted pond frog, Rana plancyi chosenica, designated as a vulnerable species by IUCN Red list. This species is a typical example facing local population threats and extinction due to human activities in South Korea. A strategic conservation plan for this endangered species is urgently needed. In order to provide information for future conservation planning, accurate information on the genetic diversity and taxonomic status is needed for the establishment of conservation units for this species. In this study, we used a molecular genetic approach using the mitochondrial cytochrome b gene and control region sequences to find the genetic diversity of gold-spotted pond frogs within South Korea. We sequenced the mitochondrial DNA cytochrome b gene and control region of 77 individuals from 11 populations in South Korea, and one from Chongqing, China. A total of 15 cytochrome b gene haplotypes and 34 control region haplotypes were identified from Korean gold-spotted pond frogs. Mean sequence diversity among Korean gold-spotted pond frogs was 0.31% (0.0-0.8%) and 0.51% (0.0-1.0%), respectively. Most Korean populations had at least one unique haplotype for each locus. The Taean, Ansan and Cheongwon populations had no haplotypes shared with other populations. There was a sequence divergence between Korean and Chinese gold-spotted pond frogs (1.3% for cyt b; 2.9% for control region). Analysis of genetic distances and phylogenetic trees based on both cytochrome b and control region sequences indicate that the Korean gold-spotted pond frog are genetically differentiated from those in China.

  • The objective of this study were to identify the state of re. cognition and attitude of residents in Seoul city about air environment and to identify factors affecting attitude toward air environment. Study object was residents in Seoul city sampled by multistage random proportional sampling. Sample size was 0.0067%(500 persons) of total residents in Seoul city. The results were divided into two parts: (1) descriptive results of recognition and attitude toward air environment, (2) results of factor analysis to classify categories of attitudes toward air environment and regression analysis to identify factors affecting attitude toward air environment. Most of resident in Seoul city recognized that air environment in Seoul city was highly polluted and was not satisfactory. Experience of damage of air pollution was reported in about 70% of residents in Seoul city. More than 60% of residents in Seoul city had concern about air environment. Attitude toward air environment were classified into four categories using factor analysis: Necessity of intervention of local government for air environment conservation, Participation of residents and enterprises for air environment conservation, Optimistic attitude about air pollution, Preference of economy. Factors affecting the above attitudes were knowledge about air pollution, knowledge about policies and institutions related air environment conservation, concern about air environment, educational level, subjective assessment of air environment, sex, marital status. In conclusion this study suggested providing information of air environment in Seoul city to the residents and to educating residents for making positive attitude about air environment conservation.

  • The purpose of this study is to establish the management plannings for the conservation and environmentally friendly use of Korean coastal wetlands. The function, economic value, and the necessity for the conservation of coastal wetlands are described. The current management status, Korean Governmental policies for the use of coastal wetlands, and their problems are surveyed and analysed. The management plannings for the environmentally friendly use of Korean coastal wetlands is suggested as follows: (1) The coastal wetlands need to be divided into 3 different regions based on PSR(Pressure, State, Response) of OECD. (2) Each region should be managed by appropriate management plans which are suggested in Chapter IV of this paper. Finally, in order to realize these management plannings the change of Governmental system and laws are suggested as follows: (1) The change of relevant laws is required. Additionally, each region should managed by proper governmental agencies. (2) The EIA(Environmental Impact Assessment) system should be improved. (3) The participation of regional people should be guaranteed in the decision making processes of the business and other important planning regarding coastal wetlands. (4) The system which primed the ecological value of coastal wetlands should be established.

  • This study is the application of a choice experiment to assess Mekong Delta urban households' preferences and motivations for ecosystem conservation in the U Minh forest. The study applied a choice modeling approach to estimate the economic values of the proposed ecosystem conservation program in the U Minh forest by accessing urban consumer preferences and their willingness to pay for the project. Discrete choice experimental data was collected from 450 residents in the cities of the Vietnamese Mekong Delta. The multinomial logit model was employed to identify consumer's stated preferences for the environmental and sustainability attributes of the conservation project. The results showed that Mekong Delta urban residents paid much attention to the proposed project to protect and develop the U Minh forest. In addition, the results showed that higher education, income, and knowledge of the U Minh forest revealed a higher likelihood of selecting the project, while the older residents would select the status quo more than the younger ones. The study also proved that the effect of participation had a strong impact on the willingness to pay for the project. The findings could be useful for policymakers to take action to raise resident's awareness and willingness to pay for the U Minh forest project.

  • People have lived with and used animals for various purposes since the Paleolithic age. Therefore, animal bone research is interesting because it can infer the status of use, determine species, and ascertain the uses of animals that lived at the time. An analysis of ancient DNA was attempted to identify the species of ancient animal bones excavated from an archaeological site. Twelve animal bones from the Geumgwan Gaya period, excavated in Bonghwang-dong, Gimhae, were used in this study. After extracting DNA from the sample, polymerase chain reaction (PCR) gene amplification was performed. Species-specific primers of livestock groups such as pig, cattle, and deer were selected and used. This livestock group was a major source of protein for people who lived on the Korean Peninsula at that time. As a result, 11 sample species were identified. This study is contributes to the restoration of past life information by applying biological technologies to archaeological sites. It is also expected that such analyses of biological remains will ultimately be used to restore historical and cultural information.

  • It remains to be determined whether there is a geographical distribution pattern and phylogenetic signals for the Mycena strains with seed germination of the orchid plant Gastrodia elata. This study analyzed the community composition and phylogenetics of 72 Mycena strains associated with G. elata varieties (G. elata. f. glauca and G. elata. f. viridis) using multiple gene fragments (ITS+nLSU+SSU). We found that (1) these diverse Mycena phylogenetically belong to the Basidiospore amyloid group. (2) There is a phylogenetic signal of Mycena for germination of G. elata. Those strains phylogenetically close to M. abramsii, M. polygramma, and an unclassified Mycena had significantly higher germination rates than those to M. citrinomarginata. (3) The Mycena distribution depends on geographic site and G. elata variety. Both unclassified Mycena group 1 and the M. abramsii group were dominant for the two varieties of G. elata; in contrast, the M. citrinomarginata group was dominant in G. elata f. glauca but absent in G. elata f. viridis. Our results indicate that the community composition of numerous Mycena resources in the Zhaotong area varies by geographical location and G. elata variety. Importantly, our results also indicate that Mycena's phylogenetic status is correlated with its germination rate.

  • 최근 국가적으로 환경정보들을 DB화하고, 체계화하며 통합하고자 하는 움직임이 활발히 전개되고 있는 있다. 이러한 노력은 특히 도시 및 지역차원에서 수립하는 법정계획인 환경보전계획의 공간계획화를 더욱 용이하게 하며, 이는 공간의 관리방향을 보다 명확하게 함으로써 토지의 보전은 물론 이용과 관련된 각종 계획들 간의 상충을 합리적으로 조정하도록 합의하는데 용이한 수단이 될 것으로 보인다. 이에 본 연구는 환경보전계획의 공간계획화를 위한 방안을 모색하였으며, 특히 환경요소 중 가장 민감한 자원으로 인식되는 생태환경을 중심으로 한 공간환경계획 수립방안을 제시하였다. 공간환경 계획 수립방안은 계획과정을 고려해 크게 1)기본방향, 2)공간정보의 수집, 3)공간환경현황 작성, 4)공간환경 관리계획 수립으로 구분하였으며, 특히 현황파악 및 계획수립 시 필요한 공간정보는 기존에 구축된 공간정보들을 최대한 활용할 수 있도록 국가나 지자체 차원에서 구축된 공간정보들을 목록화 하였다. 계획수립 시 고려되는 현황도는 토지이용(토지피복)과 자연생태 우수자원/지역 현황 작성방안을 제시하였으며, 이를 기반으로 광역생태축 계획과 보전, 복원지역 계획을 수립함으로써 생태환경을 고려한 환경보전계획의 공간화를 모색하였다. 기존연구 및 사례들을 통해 마련한 현황 및 계획방안은 경기도 지역에 적용해 봄으로써 그 활용가능성을 살펴볼 수 있었다. 이러한 계획은 관련 공간개발계획 수립 시 생태적 가치와 중요도를 고려한 계획안 마련에 기여함은 물론, 지역 내 개발사업 추진 시 계획의 적정성과 입지의 타당성을 검토하는 기초자료와 근거자료로 활용될 수 있을 것으로 보인다.

  • IUCN의 적색목록은 전 세계 규모에서 가장 신뢰받는 멸종, 희귀 동식물종의 평가와 보전 정보를 제공하고 있다. 2016년 7월까지 한반도에 분포하는 식물중 IUCN 적색목록 평가를 받은 종은 236종으로, 5종이 멸종위기종(CR), 20종이 위기종(EN), 9종이 취약종(VU)으로 확인되었다. 나머지 189종은 약관심종(LC)으로 평가되었다. 환경부는 2011년 국가적 색목록 평가라는 명목 하에 IUCN 적색목록과 내용, 형식이 다른 정성적 기준에 따라 평가 결과를 제시하였다. 이와는 별개로 환경부는 멸종위기종 I급과 II급 목록을 57종으로 수정 제시하였다. 이 목록은 IUCN의 적색목록과 비교시 일부 공통종이 있으나 공통종도 보전상의 지위가 일치하지 않는다. 이런 평가 내용의 불일치의 이유는 남한이라는 제한된 지역 수준의 평가로는 전 세계 규모의 평가와는 결과가 일치할 수 없기 때문이다. 평가에 필요한 정보가 부실하게 제시되거나 정보가 없는 상태에서 자의적 평가가 이루어진 경우도 있다. 국가 단위의 종 관리를 위해서는 멸종과 절멸에 대한 엄밀한 용어 적용과 남한에 국한된 제한적 시각의 편향된 결과를 배제하고, 분류학적 실체에 근거한 종 선정, 평가를 위한 개체군의 크기, 분포, 개체수, 개체군 증감에 대한 구체적 자료 제시와 수집이 필요하다. 환경부의 현재 멸종위기동식물 목록은 '국내절멸위기목록'으로 변경하고, 전 세계 단위의 IUCN적색목록 평가종을 '멸종위기목록'으로 이원화해서 관리할 필요가 있다. 현재 국가 기관에서 제시하는 몇 백 종의 과도한 목록 보다는 우선 평가 대상의 종을 순차적으로 늘려가면서, 평가 및 종관리에 내실을 다지는 것이 필요하다.
