For conservation of biodiversity, we designate and manage the major areas that are habitats of organisms as ecosystem protected areas. It is necessary to evaluate the biodiversity of protected areas relatively in order to establish strategies to protect and secure the biodiversity of protected areas. In this study, we selected evaluation indicators by which we can compare objectively the biodiversity of protected areas corresponding to forest ecosystem, and applied them to Mt. Jiri and Mt. Bukhan National Parks. We reviewed literatures to select evaluation criteria. Frequently mentioned criteria and the structure of the forest which plays an importantrole of forest biodiversity were selected as the evaluation criteria. As the result, the selected evaluation indicators were 7-species diversity, species richness, evenness, rarity, disturbance species, indigenous species, and forest structure. In Mt. Jiri and Mt. Bukhan National Parks, species diversity were 3.492 and 2.943, species richness were 8.998 and 9.793, evenness were 0.849 and 0.680,rarity were 11.976 and 10.783, and disturbance species index were 0.214 and 0.357 respectively. Both national parks had abundant indigenous species and showed various forest physiognomies and stable 4-layer structure. It was found that crown density was higher in Mt. Jiri. Most indicators were implied high biodiversity in Mt. Jiri and Mt. Bukhan national parks.

The Demilitarized Zone(DMZ) is a buffer zone set between the southern and northern limit lines established after the 1953 Armistice Agreement. It is an important natural environment conservation area where wild species of animals and plants live. On the other hand, the development pressure on the DMZ will increase when the inter-Korean economic cooperation is activated in the future. As a result, DMZ development should consider not only the economic cost-benefit aspects, but also how to assess and conserve the biodiversity of the DMZ, as well as the recovery costs and budget. This paper develope a sustainable DMZ management model under biodiversity uncertainly by using real option approach. The model is also designed to reflect the political risk and regional specificity of the DMZ. Through empirical analysis, I derive the biodiversity threshold (b^*) that can secure the DMZ investment economy under uncertainty. In addition, through the sensitivity analysis, I derive the factors influencing the biodiversity threshold, and suggest the policy implications for sustainable management of DMZ.

In June 1992, Convention on Biological Diversity (CBD) was concluded by 158 countries in Rio de Janeiro. And now, 194 member nations are participating in discussions for their own profit. Recently, Nagoya Protocol regarding Access to genetic resources and Benefit-Sharing (ABS) was approved and took effect from October $12^{th}$, 2014. Thus, it is important to understand the impact of CBD and ABS functioning on researchers studying marine biodiversity. Until now, in the previous Conference of the parties to the Convention on Biological Diversity, the interest towards researching marine and marine living resources was relatively low, and accordingly, the discussions regarding marine and marine living resources were delayed. However, in the $12^{th}$ Pyeongchang Conference of the Parties to the Convention on Biological Diversity, the arguments concerning Ecologically or Biologically Significant marine Areas (EBSA) and the other marine related issues were discussed. Although, South Korea has not yet officially joined Nagoya Protocol, however the consultations in regard to Prior and Informed Consent (PIC), Mutually Agreed Terms (MAT) and Global Multilateral Benefit-Sharing Mechanism (GMBSM) were discussed. We belive that as a possessing nation of biological resources, South Korean government authorities should revise their management systems protocol and regulations concerning domestic biological resources, in order to strengthen the information system and help academia and industry to utilize the biological resources abroad easily and effectively.

It has been noted that the main cause of biodiversity loss is influx of alien species. Specifically, habitats destruction, economic loss, and human injury are increasing due to invasive alien species. There were 2,167 alien species in Korea. 21 alien species of extraterrestrials including Lycorma delicatula, Solenopsis invicta, Myocastor coypus, and Spartina alterniflora at high risk through ecological risk assessment, are designated as invasive alien species. Alert species, which may have negative impact on ecosystems when they are introduced into the country, are assigned to 127 species through the ecosystem risk evaluation. To list such alien species to prevent invasion of alien species in advance, and to minimize damage caused by imported alien species, a national level management system called the Conservation and Use of Biological deversity Act was established, but there is a lack of a systematic management system in accordance with degree of risk. There is also a risk assessment chart should be developed thatreflects ecological characteristics of each taxon and evaluation criteria in predicting the risk.

자두나무(Prunus salicina Lindl.)는 세계에서 5번째로 많이 생산되는 과실로, 한국에서 재배하는 자두나무의 기본종은 중국 양쯔강 유역에서 기원했다. 2016년 과수용 자두나무와는 다른 자두나무가 양구에서 발견되었다. 양구군, 인제군, 고성군 일대의 자두나무 개체군의 유전다양성 및 집단 구조 분석을 통해 본 자두나무 개체군의 유전다양성 및 개체군 구조를 확인하고자 했다. 과수용 재배종을 포함한 시료를 채취하여 GBS 분석을 진행했고 주성분 분석과 STRUCTURE 분석을 통해 개체군간 유전적 구조를 확인했다. 재배종의 유전형이 다른 개체군에서도 나타나는 것으로 보아 유의한 유전적 분화가 일어났다고 보기 힘들었다. 하지만 고성군 고진동계곡 등 DMZ에 인접한 집단이 분계도에서 재배종 개체군과 가장 유전적 거리가 있는 것으로 나타났다. 하지만 본 분석으로는 야생집단으로 발견도니 자두나무의 실체와 기원을 단정짓기에는 부족한 것으로 보이며 외군 추가 및 더 많은 시료를 확보하는 등 추가 조사와 분석이 필요하다.

The objective of this study was to evaluate biodiversity and natural habitat environment of freshwater ecosystem. Our aim was therefore to produce a set of biodiversity and habitat indicators based on multi-parameters of water quality and biodiversity by analyzing the characteristics of the results by indicators. We selected four indicators a) anthropogenic disturbance, b) habitat diversity, c) biodiversity, d) ecosystem structure. The fishes cohabiting with Brachymystax lenok tsinlingensis were Rhynchocypris kumgangensis and Zacco koreanus. As a result of the anthropogenic disturbance evaluation, it was analyzed that vegetation embankment showed a more stable environment in the tributary than the main stream, and other disturbance was not confirmed As a result of the habitat diversity evaluation, it was analyzed that habitat evaluation index showed a high score of 200 more on average, showing an optimal habitat condition. As a result of the biodiversity evaluation, it was analyzed as a clean habitat condition with a high proportion of sensitive species, abundant dissolved oxygen, and little pollutants. As a results of the ecosystem structure, the ecological health condition metrics and appearance of endangered species showed large score deviation, but it was analyzed that the stream ecosystem health was generally excellent. There was a slight correlation between the habitat environment and the results of the nature habitat evaluation according to the appearance of the B. lenok tsinlingensis.

eDNA, an abbreviation for environmental DNA, means DNA derived from organisms inhabiting in a specific environment. The utilization of eDNA extracted from environmental samples allows for efficient and accurate monitoring of organisms inhabiting the respective environment. Specifically, eDNA obtained from seawater samples can be used to analyze marine biodiversity. After collecting seawater samples and extracting eDNA, metagenome analysis enables the taxonomic and diversity analysis among marine organisms inhabiting the sampled area. This review proposed an overall process of marine biodiversity analysis by utilizing eDNA from seawater. Currently, the application of eDNA for analyzing marine biodiversity in domestic setting is not yet widespread. This review can contribute to establishment of marine eDNA research methods in Korea, providing valuable assistance in standardizing the use of eDNA in marine biodiversity studies.

To distinguish manchurian clematis, Clematis terniflora var. mandshurica and three-leaf clematis, C. apiifolia, we collected 9 nuclear ITS sequences and two sequences of trnQ-trnH intergenic spacer and trnH region in GenBank database. Those sequences were aligned to find differences between those of C. terniflora var. mandshurica and C. apiifolia. Two primer pairs were newly designed base on the differences between two species and conducted multiplex PCR. The size of amplified fragments using generated primers were 380 base pairs (only three-leaf clematis) and 189 base pairs (both species). This genetic marker based on PCR is useful to discrimination of C. terniflora var. mandshurica and C. apiifolia
