  • We created species richness maps of mammals, birds and plants using "Nnational Ecosystem Survey" data and identified correlations between species richness maps of each taxa. We examine the distribution of species richness of each taxa and calculated conservation priority rank through plotting species-area curves using an additive benefit function in Zonation. The conclusions of this study are as follows. First, plant showed high species richness in Gangwon province and Baekdudaegan, and mammals showed high species richness at eastern slope of Baekdudaegan in Gangwon province unusually and the species richness of mammals distributed equally except Gyeonggi and Chungnam province. However, birds showed high species richness in the west costal because the area is the major route of winter migratory birds. Second, correlation of each taxa's distribution is not significant. Correlation between mammals and birds is positive but correlations between birds and others are negative. Because mammals inhabit in forest but birds mostly live in coastal wetlands and rivers. Therefore, bird's habitats are not shared with other habitats. Third, the probability of mammals occurrence is very low under 25% in species-area curve, others increase proportionally to area. Birds increase dramatically richness at 10% because bird's habitat is concentrated in coastal wetlands and rivers. Plants increased gently species richness due to large forest in Gangwon province. We can calculate the predicted number of species in curves and plan various conservation strategies using the marginal number of species. Finally, high priority ranks for conservation distributed mainly in Gangwon province and Baekdudaegan. When we compared with priority map and terrestrial national parks, the parks were evaluated as high priority ranks. However, the rank of parks away from Baekdudaegan was low. This study has the meaning of selecting conservation priority area using National Ecosystem Survey. In spite of the omission of survey data in national parks and Baekdudaegan, the results were good. Therefore, the priority rank method using species distribution models is useful to selecting protected areas and improving conservation plans. However, it is needed to select protected areas considering various evaluation factors, such as rarity, connectivity, representativeness, focal species and so on because there is a limit to select protected area only using species richness.

  • The nerippe fritillary butterfly, Argynnis nerippe, is listed as an endangered species in Korea. Establishment of effective conservation strategies can be aided by the development and application of molecular markers that can be used to investigate the population genetics of the butterfly. Therefore, in this study, we identified ten microsatellite markers specific to A. nerippe using the Next-Seq 500 platform, and applied these markers to investigate the characteristics of five South Korean butterfly populations. Genotyping of 48 A. nerippe individuals from five localities showed that at each locus the number of alleles ranged from 4 to 14, and that the observed and expected heterozygosities were 0.324-0.863 and 0.138-0.985, respectively. Significant deviation from the Hardy-Weinberg equilibrium was not observed at any locus. Population structure analysis indicated that there are two genetic groups in Korea, but no population-based gene pool assignments were found. Analysis of $F_{ST}$, $R_{ST}$, and a principal coordinates analysis suggested that the Gureopdo and Yaecheon populations were isolated from other populations. Genetic isolation of the Gureopdo population may be a consequence of unequal population change between Gureopdo and inland populations and to the offshore habitat of Gureopdo. Genetic isolation of the Yaecheon population may be a consequence either of the southernmost location of the population or of the limited sample size available. Further studies with increased sample sizes will be necessary to draw robust conclusions on population isolation and to devise conservation strategies.

  • We investigated death rates, growth rates and recruitment of culms in two neighboring bamboo (Phyllostachys bamboosoides) stands nested in by two different bird species to analyze stand structure and to design conservation strategies. A third bamboo grove not used by birds, the Taewha stand, was included as a control stand. The bamboo stand occupied by birds in the family Ardeidae (the Ardeidae stand) had an approximately 1.5 times higher culm density than the stand occupied by birds in the family Corvidae (the Corvidae stand). The crude death rate and the number of newly emerged shoots were also higher in the Ardeidae stand than the Corvidae stand. The death rate for bamboo in the Ardeidae stand was not dependent on diameter at breast height (DBH) and was almost 40% for culms of all sizes, whereas most dead culms in the Corvidae stand were < 4 cm DBH. Consequently, we conclude that in the Ardeidae stand, density-independent causes of death are operating, while density-dependent factor are more important in the Corvidae site. The results of soil analysis in these stands suggest that the density-independent death pattern observed in the Ardeidae stand may be due to soil acidification resulting from wastes produced by the birds during breeding. On the other hand, the culm distribution and death patterns in the Corvidae stand suggest that the stand characteristics were not affected by the nesting birds. These results suggest that different conservation strategies must be applied to conserve bamboo groves used by ardeids and corvids for nesting.

  • The current world wide interest in environmental issues has moved from energy conservation to $CO_2$emission reduction. Recently, according to the increase in demand for water resources, insufficient potable water circumstance is supposed, unless there are corresponding in crease in water conservation and water recycling. This study has attempted to analyze $CO_2$emission reduction by water saving strategies like installation water saving devices, rain water harvesting and grey water system. To do this, this research investigates applicable water conservative strategies by literature review and calculated total water saving. The results show that (1) firstly, the water usage and $CO_2$ emission could be reduced up to 44%, (2) $CO_2$ emission reduction by water saving devices and rainwater harvesting system is about 47.7%, and (3) water usage and $CO_2$ emission reduction by grey water system is about 66%. In the future, this paper will be utilized for water management from the early design stage to maintenance stage of water glutton building.

  • This study assesses forest fire susceptibility in Gangwon-do, South Korea, which hosts the largest forested area in the nation and constitutes ~21% of the country's forested land. With 81% of its terrain forested, Gangwon-do is particularly susceptible to wildfires, as evidenced by the fact that seven out of the ten most extensive wildfires in Korea have occurred in this region, with significant ecological and economic implications. Here, we analyze 480 historical wildfire occurrences in Gangwon-do between 2003 and 2019 using 17 predictor variables of wildfire occurrence. We utilized three machine learning algorithms—random forest, logistic regression, and support vector machine—to construct wildfire susceptibility prediction models and identify the best-performing model for Gangwon-do. Forest and soil map data were integrated as important indicators of wildfire susceptibility and enhanced the precision of the three models in identifying areas at high risk of wildfires. Of the three models examined, the random forest model showed the best predictive performance, with an area-under-the-curve value of 0.936. The findings of this study, especially the maps generated by the models, are expected to offer important guidance to local governments in formulating effective management and conservation strategies. These strategies aim to ensure the sustainable preservation of forest resources and to enhance the well-being of communities situated in areas adjacent to forests. Furthermore, the outcomes of this study are anticipated to contribute to the safeguarding of forest resources and biodiversity and to the development of comprehensive plans for forest resource protection, biodiversity conservation, and environmental management.

  • 북방계 식물들의 잔존적 피난처인 아고산대에 분포하는 식물들은 기후변화에 따른 자생지 환경변화로 인해 멸종 및 멸절 위험에 크게 직면해 있는 실정이다. 본 연구는 한반도의 남부지역 아고산대에 제한적으로 분포하고 있는 특산식물이며 희귀식물인 설앵초(Primula farinosa subsp. modesta (Bisset & Moore) Pax)에 대한 유전적 다양성과 지리적 분화 양상을 구명을 통한 보존전략을 수립하기 위해 3지역 6집단 165개체를 대상으로 ISSR (Inter Simple Sequence Repeat) 분석을 수행하였다. 그 결과 집단 수준의 유전 다양성의 평균은(P = 60.62, SI = 0.299, h = 0.190) 유사한 생활사를 갖는 다년생 초본류의 평균보다 낮은 수준이었으며, 이형화주의 특징을 갖는Primula속의 근연 분류군들에 비해서도 다소 낮은 결과를 보였다. 유전적 분화도 구명을 위해 AMOVA(Analysis of molecular variance) 분석 결과 전체 유전변이 중 약 50%가 지역 간에 분포하는 결과를 보여 종내 지역간 분화도가 매우 높은 수준으로 판단되며, Bayesian cluster 분석 결과에서도 조사된 세 지역이 각각 독특한 유전적 cluster를 형성함으로써 개체군간 유전자 이동이 매우 제한적임을 암시하였다. 따라서 설앵초 집단의 급속한 분획화와 낮은 수준의 유전적 다양성, 지역간 높은 분화도 등의 특성들을 고려하여 설앵초 집단의 개체군 감소 및 멸절 방지를 위한 현지 내 외 보전 전략 수립이 시급한 것으로 판단된다.

  • 우리나라에 있는 보호지역의 보존 및 관리에 대한 제반 문제의 해결을 위한 한 접근방법으로 도서생물지리학과 서식처 분획화 이론의 적용에 대한 검토를 하였다. 최근 생물적 다양성의 파괴와 함께 급격히 증가하고 있는 보호지역내 자연 서식처에 대한 적절하고 신속한 조치가 필요하며. 이러한 요구에 부응하여 우리나라 보호지역의 효과적인 관리를 위한 제반 검토를 하였다. 우리나라의 식물상은 주로 인간의 간섭에 의해 계속 변화할 것이다. 다양한 내용의 위협에 처해 있는 우리나라 보호지역의 보존과 관리에 대한 이의 바람직한 해결을 위해서는 결과적으로 동, 식물상 또는 집단이나 종 등의 개별적인 접근이 아닌 종합적인 접근방법을 필요로 하고 있다. 이러한 접근방법은 서식처, 종 및 집단의 관리에 대한 위협의 종류, 유효성과 잠재성 등을 종합적으로 평가할 수 있기 때문이다. 우리나라 보호지역의 보존전략에 대한 도서생물지리학과 서식처 분획화 및 주연부효과 이론 등의 적용은 현존의 서식처 패치에 대한 격리 및 분획화등의 역동적인 관계에 대한 이해를 보다용이하게 해주게 될 것이다. 또한 이러한 접근방법은 우리나라 식물상의 분포특성 및 현상에 대한 제반 지식에 기초를 둔 식물의 보존책의 하나로 이는 우리나라의 보호지역의 보존에 대한 보다 합리적인 접근방법이 될 것이다. 또한 이러한 적용을 기초로 하여 최소활성화집단의 규모 등의 개념 도입은 식물과 서식처 보존의 보다 바람직한 해결을 위한 종합적인 한 방법이 되리라 생각된다.

  • Siberian chipmunks, Tamias sibiricus, are one of several popular companion animals found in the pet shops of South Korea. At present, however, there have been no studies done in South Korea examining their origin even though they could be potential carriers of zoonotic diseases, and are a species of concern for efficient conservation and management strategies. Sequences of the mitochondrial cytochrome b gene (1140 bp) were determined to investigate the origin of Siberian chipmunks sold in four South Korean pet shops through comparison with sequence data from animals of known locality. Nine Siberian chipmunks were collected from pet shops in South Korea, which resulted in nine haplotypes. One (AR) of these coincided with the haplotype previously described. Phylogenetic and network analyses using 53 haplotypes including 45 haplotypes from GenBank showed three phylogenetic groups in South Korea, almost concordant to locality, designated as northern, central, and southern parts as described in a previous study. Of the nine individuals examined from the pet shops, eight were clustered into the northern phylogroup but one (cgrb9153) was grouped with the southern phylogroup, implying that at least the Siberian chipmunks examined in this study did not originate from other countries. It is likely that most individuals sold in the pet shops of Seoul were caught in the wild in Gyeonggi-do and Gangwon-do, or are maternal descendants of captive-bred individuals originating from the northern part of South Korea. It is recommended that conservation and management units of Korean chipmunks should be examined in further detail.

  • 문화유산의 현색(顯色)은 제작기법 해석, 보존처리 활용, 상태 모니터링의 중요한 기초 자료이다. 이 연구에서는 권응수 초상을 대상으로 디지털 색관리시스템 기반 색재현 과정을 체계적으로 정립하고, 문화유산 기록 및 보존에 적합한 현색 활용방안을 제안하였다. 전체적인 색재현 과정은 촬영 환경 세팅, 색기준차트 측정, 디지털 사진 촬영, 색보정, 색공간 설정 순으로 진행되었다. 연구 결과, 사진기 제조사 프로파일이 적용된 디지털 이미지는 현색과 비교하여 평균 𝜟10.1의 색차를 보인 반면, 디지털 색재현 이미지는 평균 𝜟1.1의 색차를 보여 현색과 거의 유사한 것을 알 수 있다. 이 결과는 디지털 사진 촬영 환경과 조건을 최적화했더라도 디지털 사진기 제조사의 보정 알고리즘에 의존할 경우 대상 문화유산의 현색 기록에 어려움이 있는 것을 의미한다. 따라서 문화유산은 RAW 이미지 기반의 색보정 및 색공간 설정을 통해 디지털 색재현이 필요하며, 이는 현색 기록화를 위해 매우 중요한 과정이다. 또한 디지털 색재현을 통한 현색 기록은 문화유산의 보존상태 평가와 보존처리 및 복원의 중요한 기초자료가 될 수 있으며, 퇴색 및 변색 현상의 모니터링을 위한 기준 데이터로 활용성이 높을 것으로 판단된다.
