  • 한국산 냉수성 어류 새미 Ladislabia taczanowskii Dybowski의 분포양상 및 서식지 특징, 멸종위협을 평가하기 위해 2021년 3월부터 8월까지 분포조사를 실시하였다. 과거 출현기록은 1997~2005년, 2006~2012년, 2013~2019년으로 구분하였고, 분포조사는 169개 지점을 조사하여 72개 지점에서 1,040개체가 채집되었다. 서식이 확인된 지역은 남한강(27지점), 임진강(17지점), 북한강(16지점), 삼척오십천(4지점), 연곡천(3지점), 강릉남대천(2지점), 전천(1지점), 추천(2지점)이었다. 새미의 주 서식지는 고도가 300 m 이상의 상류로 유폭은 2~30 m, 수심은 0.3~1.5 m이며 하상은 큰돌의 비율이 50~90%, 돌의 비율이 10~50%인 곳이었다. 새미의 위협요인으로는 보의 축조와 댐건설, 교량공사, 골재 채취 등의 하천공사와 생활 하수유입, 유원지, 태풍으로 인한 홍수 및 복구공사 등이었다. IUCN 평가기준에 따른 멸종위협 등급은 2010~2019년 대비 서식지 감소율(36.1%), 출현범위(7,820 km2), 점유면적(288 km2), 지소수(19개), 서식지 질 하락 등을 근거로 취약(Vulnerable, VU A2ac)으로 평가되었다. 마지막으로 새미의 보존방안에 대해 논의하였다.

  • 잔가시고기 Pungitius kaibarae의 분포양상 및 서식지 특징, 멸종위협등급을 평가하기 위해 2018년부터 2020년까지 분포 조사를 실시하였다. 과거 출현지점 수는 1980~1996년, 1997~2005, 2007~2017년으로 구분하여 정리한 결과, 각각 32개, 43개, 64개 지점이었다. 분포 조사는 75개 하천, 193개 지점을 조사하여 26개 하천, 39개 지점에서 1,400개체를 채집하였다. 잔가시고기는 주로 고도가 낮고 유속이 느리며 수초가 많은 하천 하류 또는 기수역에 서식하였다. 위협요인으로 가뭄 및 홍수, 홍수복구와 하천정비 공사, 교량 건설, 외래종 배스의 포식 등이었다. IUCN 평가기준에 따른 멸종위협등급을 평가한 결과, 10년 동안 서식지 감소율 42.6%, 서식지의 질적 하락, 외래종 배스의 확산 및 영향 등을 근거로 취약(Vulnerable, VU A2ace)으로 평가되었다. 따라서 잔가시고기는 환경부 멸종위기종으로 재지정하고 체계적으로 관리해야 할 것이다.

  • 본 연구는 대표적인 아고산식물인 동일속 식물 구상나무와 분비나무의 기후변화 민감성 평가에 목적이 있다. 이를 위해 종 분포 모형을 이용하여 현재 및 미래의 종 분포 확률을 예측하였고 기후변화 민감성 평가를 하였다. MTSS를 기준으로 예측된 잠재 분포지는 분비나무가 구상나무보다 감소율이 많았으며, 스칼라 민감도를 이용한 평가에서는 구상나무의 민감도가 분비나무보다 높았다. 본 연구와 같은 종 분포 모형을 이용한 연구에서는 위치자료 및 환경변수에 따라 종 분포 확률이 달라질 수 있으므로 연구 대상종의 생태 환경에 대한 면밀한 조사가 선결되어야 하며, 본 연구를 기초로 하여 국내에 적용 가능한 기후변화민감성 평가 방법이 개발된다면 기후변화와 생물 다양성 적응 정책의 중요한 의사결정 수단이 될 것으로 기대한다.

  • The gold-spotted pond frog(Pelophylax chosenicus) classified as an Anura in Amphibia is sharply decreasing due to various changes of habitats environment, and designated as IUCN Red List Threatened species(VU; Vulnerable) internationally and domestic endangered species Class-II; therefore, it's in urgent need of the research on habitats restoration of the gold-spotted pond frog in order to prevent its extinction. This study was carried out to verify the effect after restoration by introducing the inhabitation elements deducted by the literature research and a field survey on the habitats for the gold-spotted pond frog in danger of regional extinction in the urban area of Ansan city, Gyeonggi-do, Korea. Accordingly, the capacity for bio-species was increased by expanding the area of habitats into $11,845m^2$, and securing the place for hibernation and corridors and discharge within the habitats, etc. As a result of the monitoring the number of individuals increased by 9.5 times as the reproductive success rate of the gold-spotted pond frog got higher, and by virtue of improvement in the habitats, biodiversity increased to 183 species(4 species of amphibians and reptiles, 4 species of mammals, 17 species of birds, 53 species of insects(terrestrial/Benthic), 4 species of fish, and 102 species of plants). It might be possible to verify the restoration effect of the habitats through continuous monitoring, and suggest the restoration model on the habitats for continuously survivable the gold-spotted pond frog in the urban area by deducting the matters to be improved.

  • Large scale marine biodiversity studies in China have been carried out for more than half a century since the founding of the Institute of Oceanology, CAS, in 1950. Through a series of coastal and multi-disciplinary oceanographic investigations in the shelf seas and biodiversity studies since the late fifties, a total of 20,278 species of marine biota have been recorded upto 1994. Recent intensive studies have further revealed the richness of marine biota of the China seas,a great number of marine species have been found and many new taxa established. The total species number of main biotic groups increased about 50 % of that estimated in 1994. The results have promoted the fast development of China's marine fisheries, medicine (drug) and biodiversity research, and attracted many scientists, particularly bio-technologists, to join their studies. Environmental deterioration and human activity strongly stressed the sustainable development and conservation of marine bio-diversity, and resulted in the increase of end angered species as record ed in the new published ${\ll}$China Species Red List${\gg}$ with the threatened category of species assessed by adopting the new IUCN criteria. To further reveal the high diversity and their history, present status and future of marine organisms existed in the world ocean, an international Project ${\ll}$Census of Marine Life (CoML)${\gg}$ was established in 2000 in the USA. Scientists predicted that 2 to 3 times of numbers of the known species will possibly be found in various marine habitats, particularly the abyssal ocean. The Research Plan and the Projects were briefly introduced, and the relationship between marine biodiversity and biotechnology was discussed. The Project planned to apply new and high techniques and new equipments on board research vessel and in laboratory. Brief review of recent advances of Chinas' marine biodiversity and biotechnology studies indicated that fascinate results have been achcieved; but further effort should be made to promote the continuous advance of our basic researches and their application in related production and maintain sustainable development.

  • 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.
