        To determine the status of Korean wild reptiles and amphibians infection and relation with climate change of Korean peninsula, references were reviewed. Wild animals serve as intermediate, reservoirs and paratenic hosts to zoonotic parasites of human beings. The parasites and disease can be a serious problem for all herptiles. The infectious diseases, in particular, become parasitized through contact with other reptiles or contaminated objects and environments, or by eating infected food items. Worms are one of the most common intestinal parasites. Among reptiles, the most common infections are flatworms (trematodes), roundworms (nematodes), tapeworms (cestodes), and spiny-headed worms (acanthocephalans). A total of 20 species for infectious diseases from Korean wild reptiles and amphibians has been reviewed. Among them, 11 species was amphibians and 9 species for reptiles. The Korean wild herptiles had total 41 kinds of parasite pathogenic organisms. Meximum infections belonged to Rana nigromaculata as amphibians had 22 kinds of parasite organisms, including Gorgodera aponica, Gorgodera bombinae, Diplodiscus japonicus, Haematoloechus sibiricus japonicus, Pleurogenoides japonicus, Haematoloechus nanchangensis, Haematoloechus variegatus, Haematoloechus lobatus koreanus, Neodiplostomum seoulense, Halipergus japonicus, Haematolechus japonicus, Loxogenes liberum, Baerttia japonica, Ophiotaenia manae, Oswardcruzia lualata, Icosiella kobayashi, Pharyngodon pobypedates, Gyrinicola japonica, Catadiseus sp., Ophisthodiseus sp., Diplorchis sp., and Sparganum. Also, Dinodon rufozonatum as reptiles had 5 kinds of parasite, including Cotylaspis coreensis, Cotylaspis sinensis, Cephalogonimus japonicus, Astiotrema reniferum, Astiotrema odheri, Kaurma orientalis, and Astiotrema sp.. In the future, under the climatic extremes on Korean peninsula such as floods, drought and temperature variability, in particular, the susceptibility of amphibian and reptiles to infection will be increased and they have implications for the emergence of disease and the potential for climate change to exacerbate amphibian decline.

        지난 수십 년 동안, 변화하는 기후를 이해하기 위해 많은 연구가 있었고, 여러 기후 변량의 변화추세가 발견되었다. 이들 추세를 설명하기는 쉽지 않 고, 때로는 서로 모순적으로 보여지기도 한다. 다양한 기후 변량의 변화추세를 일반적으로 설명하기 위한 가설을 제시하기 위해 많은 시도도 있었다. 어느 정도 지식이 축적된 이 시점에서, 우리 시대에 진행되는 기후 변화에 대해 우리가 알고 있는 것을 되돌아보고 신중히 정리해볼 필요가 있다. 여기서는 기온, 일사량, 풍속, 증발, 강수에 초점을 맞추어 변화하는 기후에 대해 우리가 얻은 지식을 종합적으로 살펴보고자 한다. 온난화, 흐 려짐, 잔잔하기로 대변되는 주요 변화추세 및 증발의 역설, 강수 변동성의 증가를 서울 지점 자료를 예시로 들어 설명한다. 이러한 변화에 대한 이해를 근거로 수문학자와 공학자들에게 네 가지 함의를 제시하려 한다.

        The purpose of this study is to quantify the magnitudes of projected 21st century temperature changes and shifting climate zones over Mt. Halla, Korea based on high-resolution (1km×1km) climate change scenario data sets down-scaled from a global climate model (HadGEM2-AO) simulations using PRIDE (PRISM based Downscaling Estimation Model) as well as the simulations of a Regional Climate Model (RCM; HadGEM3-RA). The high resolution climate data demonstrate that the magnitudes of increases in coldest and warmest monthly mean temperatures over Mt. Halla will exceed those of the averages across the Korean Peninsula during the 21st century, leading to the shifts of climate zones. The isoline with 5°C (20°C) of the coldest (warmest) monthly average temperature associated with sub-tropical (sub-alpine) climate zones will migrate from 100~230m (950~1,300m) to 300~500m (1,300~1,600m) of altitude in the late 21st century (2071~2100) under the RCP 4.5 scenario. These changes are expected to be more obviously observed in the south flank of Mt. Halla as well as under the RCP 8.5 scenario. These results indicate that changes in climate zones will lead to the extinction of sub-alpine ecosystems over Mt. Halla due to increases of summertime heat stress as well as to the expansion of the sub-tropical forest zone toward mid-mountain regions due to reduction of wintertime stress in the warmer 21st century.
