Araneae species are predators in natural ecosystem interact with various prey species. These linkage can be affected under climate change because species react not just individually but systematically. We focused on potential impact of climate change in Araneae fauna in national scale. In this study, potential species richness of Araneae in South Korea was predicted with MaxEnt (Maximum Entropy) model. Korea Forest Research Institute conducted national scale research of wandering arthropods. They monitored in uniformly set 366 points, and the data contain exact GPS points of study sites. Occurrence data were extracted from Prediction of Distribution and Abundance of Forest Spiders According to Climate Scenario (Korea Forest Research Institute, 2013). With the report, dominant 21 Araneae species that appeared more than 10% study sites were selected to estimate species richness. Training climate data were prepared from observation source of Korea Meteorological Administration. RCP 8.5 scenario data which represent future (2050, 2070) climate condition were downloaded from WORLDCLIM web site. In MaxEnt simulation, occurrence data for 21 species and 19 bioclimatic variables were used. Because the model outputs are expressed in index, the minimum training presence threshold rule was applied to distinguish presence/absence of each 21 species distribution model. We overlaid whole 21 thresholded output to get species richness map. The fluctuation between current and future species richness was calculated to observe changing trend in national scale. The results of Araneae fauna tends to move higher altitude and latitude. Species richness of lowlands is predicted to be diminished, but higher mountains are expected to be more suitable for many spider species. In some South Western coastal areas showed reduced richness in 2050 but will recover in 2070.

Thc climate change has the potential to significantly modify the actual distribution of insect pest with unknown consequences on agricultural systems and management strategies. In this study, Thrips palmi Karny was selected to predict distribution under climate change. T. palmi was introduced and first recorded in 1993 in Korea, and has become a serious pest of vegetable and ornamental crops. The MaxEnt was applied to T. palmi to predict its potential geographic distribution in Korea and Japan under the RCP 8.5 climate changing scenario. The MaxEnt software package is one of the most popular tools for species distribution and environmental niche modeling. The habitat prediction model of T. palmi in Korea was validated by the distribution of T. palmi in Japan. Based on the MaxEnt modeling, T. palmi would expand their potential distribution to whole Korean peninsula except the alpine region in Gangwon-do and Yanggang-do and Hamgyeongbuk-do in 2070s. Therefore, the monitoring system and management strategy for T. palmi should be reconsidered and re-evaluated.

최근에 지구는 CO2 농도가 급격히 증가하고 기온을 빠르 게 상승시키고 있으며, 근년에 들어 상승이 가속화되고 있 다. 인위적으로 발생하는 CO2 농도의 증가는 지구온난화의 가장 큰 원인이다. 대기 중 CO2 농도는 산업화 이전에 약 280ppm 이었으나, 2009년에는 약 385ppm으로 산업화 이 전에 비해 38% 증가하였다. IPCC에서 예측한 SRES 시나 리오 중 B1 시나리오에 따르면 2100년에는 대기 중 CO2 농도가 약 550ppm, 지구의 평균 표면온도가 약 2℃ 증가한 다고 예측하고 있다. 식물 생육에서 중요하게 생각되는 환 경요인은 광, 수분 및 영양소이며, 기후변화도 식물의 생육 및 생태적 지위에 영향을 미친다. 또한, 식물마다 종 특이성 을 갖고 있기 때문에 CO2 농도와 온도에 따른 식물의 생장 특성의 영향은 다양하며 복합적으로 이루어진다. 지구온난화에 따른 식물의 생육반응 연구와 생태적 지위 에 관한 연구는 국내․외를 포함하여 소수에 불과하며, 특히 지구 온난화 조건에서 식물의 여러 가지 형질을 이용한 생 육반응 분석과 생태적 지위에 관한 연구는 찾아보기 힘든 실정이다. 따라서, 본 연구는 상승된 CO2 농도와 온도가 낙엽성 주요 우점종 중 상수리나무, 굴참나무 및 졸참나무 의 생육 및 생태적 지위에 어떠한 영향을 미치는지 알아보 기 위해 기후변화(지구온난화) 조건을 유지시켜 생육시킨 후 그 결과를 상호 비교하였다. 대조구는 대기 중의 CO2 농도를 그대로 반영하였고, 온난화처리구는 대조구보다 CO2 농도는 약 1.6배, 온도는 2.2℃ 상승시켜 기후변화 예 측 시나리오 중 B1 시나리오와 유사하게 처리하였다. 참나무 3종의 생육반응 결과, 상수리나무와 굴참나무는 온난화처리구에서 수분이나 영양소 환경보다 광 환경에서생육반응의 차이가 컸고, 낮은 광 환경에서 더욱 크게 반응 하였다. 졸참나무는 광, 수분 및 영양소 환경에서 생육반응 의 차이가 크지 않았다. 생태적 지위폭 결과, 상수리나무는 대조구보다 온난화처리구의 광 구배에서 넓어졌고, 수분 및 영양소 구배에서는 좁아졌다. 굴참나무는 대조구보다 온난화처리구의 광, 수분 및 영양소 구배에서 좁아졌다. 졸참나무는 대조구보다 온난화처리구의 광 구배에서 넓어 졌고 수분과 영양소 구배에서는 좁아졌다. 생태적 지위 중 복역 계산결과, 상수리나무와 굴참나무는 대조구보다 온난 화처리구의 광 구배에서 넓어졌고, 수분과 영양소 구배에 서는 좁아졌다. 이러한 결과로 두 종은 광 환경에 대한 경쟁 이 심해지고, 수분과 영양소 환경에 대한 경쟁이 약해질 것으로 판단된다. 상수리나무와 졸참나무는 대조구보다 온 난화처리의 광, 수분 및 영양소 구배에서 좁아졌다. 이러한 결과로 두 종은 광, 수분 및 영양소 환경에 대한 경쟁이 약해질 것으로 판단된다. 굴참나무와 졸참나무는 대조구보 다 온난화처리구의 광과 수분 구배에서 좁아졌고, 영양소 구배에서 넓어졌다. 이러한 결과로 두 종은 광과 수분 환경 에 대한 경쟁이 약해지고, 영양소 환경에 대한 경쟁이 심해 질 것으로 판단된다. PCA 분석에 의하면, 대조구와 비교하 여 온난화처리구에서 상수리나무와 굴참나무가 더욱 가까 이 배열하였고, 졸참나무는 상수리나무와 굴참나무로부터 멀리 배열하였다. 이상의 결과로 볼 때 지구온난화가 진행되면 상수리나무와 굴참나무는 유사한 생태적 지위를 가지고 있어 경쟁이 더욱 심해질 것이며, 졸참나무는 지구온난화가 진행되어도 상수리나무 및 굴참나무와는 경쟁이 심하지 않을 것으로 예상된다.

It is expected that the temperature in Pyeongyang will be similar to that (16.6℃) in Seogwipo in the late 21st century, and most of South Korea will enter the subtropical climate due to climate change. Change in the precipitation pattern like the range of fluctuation caused by climate change will lead to expanded uncertainty in securing reliable water supply, along with a serious impact on demands for living and industrial water due to change in the volume and period of river outflow. As industrial water for production activities is estimated based on the contract quantity, it is difficult to apply rationalization of water usage and incentives in water recycling. Therefore many companies are making efforts in complying with the effluent standard while spending few resources on such rationalization and recycling. This study researched water risk management over 115 Korean companies by 28 questions in 4 categories. Through the research, this study aims to understand water risk management levels and seek response plans.

Global climate change is significant issue in marine ecosystem and fishery market. According to rising of both seawater temperature and sea-level, global fishery environment and marine ecosystem are changing drastically. Moreover, over-exploitation in fishery areas is the most important issue in the marine ecosystem conservation. In analysis and statistics of global network, major fish populations are decreasing very fastly, but fish catch are increasing annually. It means balance between product and consume is not appropriate in the global market. China as emerging new fish consumer in the world is strongly developing fishery industry and technology. In this paper, I try to review a relationship between marine ecosystem and climate change in global scale according to references. I also suggested possibility of sustainable global fishery in changing marine ecosystem by analysis of some related reports of international global fishery.

This study indicates that 84.5% of fishermen have perceived climate change and 74.9% of fishermen have responded that frequency and intensity of the impacts of climate change are increasing. The results of regression analysis have shown that the level of fishermen experiencing the impacts of climate change differs according to individual’s characteristics including age, length of experience, sea area (fishing area) and types of fisheries. About half of the respondents have shown that they are not taking any actions against the effects of climate change. The main reasons are that they either have lack of knowledge on how to respond to the impacts of climate change or have the perception that climate change is irresistible. The majority of respondents have responded that they are not aware of the government’s climate change policy and emphasized that it is necessary to have effective countermeasures strengthening the provision of information about climate change policy. The result of perception survey have highlighted that it is essential for the government and the fishermen to share relevant information and to consider method of cooperation.

Although in 2011 Japan finally decided not to participate in the second commitment period of the Kyoto Protocol to the United Nations Framework Convention on Climate Change, under the principles of sustainable development and common but differentiated responsibilities, it has probed the ways in which the ‘ultimate objective’ of the UNFCCC will be realized in the international community. With regard to socalled ‘emissions trading,’ since the middle of the 2000s, Japan has continuously adopted various methods and approaches for domestic emissions trading at local and central government levels. This article analyzes Japan’s recent efforts in introducing emissions trading schemes and finally refers to the Joint Crediting Mechanism, which covers the period until a future new agreement under the UNFCCC comes into effect.

PCA 분석에 의하면, 대조구와 비교하여 온난화처리구에서 상수리나무 와 굴참나무가 더욱 가까이 배열하였고, 졸참나무는 상수리 나무와 굴참나무로부터 멀리 배열하였다. 이상의 결과로 볼 때 지구온난화가 진행되면 상수리나무와 굴참나무는 유사 한 생태적 지위를 가지고 있어 경쟁이 더욱 심해질 것이며, 졸참나무는 지구온난화가 진행되어도 상수리나무 및 굴참 나무와는 경쟁이 심하지 않을 것으로 판단된다.

Insects reflect climate change dramatically because insects are poikilotherm and have huge biodiversity. Also, the prediction of insect distribution is very significant due to the position of this group giving diverse ecological services including their extraordinary economic importance. Accurate modeling of geographic distributions of insect species is crucial to various applications in ecology and conservation. The best performing techniques often require some parameter tuning, which may be prohibitively time-consuming to do separately for each species, or unreliable for small or biased data sets. The purpose of this study is to introduce and compare several models to predict insect distribution under climate change in Korea. This work would be helpful to researchers or decision makers by giving practical advice, for example, kinds of input/output data, applicability to GIS, to select appropriate model to predict insect distribution.

Model systems, if applied appropriately, give useful and rapid predictions of the potential distribution and population dynamics of the target species. Insect populations are poikilothermal animal and readily applied to model systems in several ways. Classical insect population models are focused on management purposes, for example, prediction of first occurrence period after cold weather season. Insect populations are distributed neither uniformly nor at random, or they are aggregated in patches, or they form gradients of other kinds of spatial structures which are closely related to their natural resources. Thus, developing insect population models should be considered not only with their physiological development and/or occurrence but also with their spatial distributions including their hosts. In this study, we discuss spatial distribution model of insect population with their host in order to future climate change scenario in Korea.

본 연구는 MODIS 위성영상을 이용하여 광역적으로 진행되고 있는 식물계절학적 특징을 분석하고자 수행하 였다. 위성영상을 이용한 식물계절학적 특징 분석은 현 장 관찰 자료의 분석을 위한 전반적인 식물계절 경향성 및 변동성에 필요한 정보를 제공해 줄 수 있으며, 현장 관찰 값과 광역 식물계절 관측 값의 연결을 통하여 광 역 수준에서 보다 정밀도 높은 식물 계절현상 모니터링 을 가능하게 한다. 본 연구의 기반이 된 MODIS EVI 자료는 Timesat Algorithms의 double logistic function으로 평활화시켜 분석하였다. 제주→남해안→지리산→소백산→설악산 의 위도 분포에 따라 식물계절 시작일은 늦어지는 경향 을 보였다. 그러나 11년간 주요 산림 지역에서의 식물 계절 시작은 해마다 시작일에 다르게 나타나는 연변동 의 특징을 보였다. 변동 자료를 고차다항식으로 변형한 결과, 제주도는 연간 0.38일, 소백산지역은 0.174일 계 절 시작이 늦어지고, 남해안은 0.32일, 지리산은 0.239 일, 설악산 지역은 0.119일 개엽일이 빨라지고 있는 것 으로 나타났다. 우리나라 전체 식물계절 시작 시기의 특징을 공간적 으로 살펴보면, 주요 산림 지역은 늦어지고, 분지나 산 록의 남사면지역에는 빨라지는 것으로 나타났다. 지역적 으로 살펴보면, 제주도의 남서해안 및 북동해안 사면지 역, 동남해안 지역이 빠른 경향을 보였다. 행정구역별 식물계절 시작 시기를 분석한 결과, 2001 년에는 서울과 경기도, 동해안, 남해안, 마산, 창원, 밀양, 대구, 제주도를 중심으로 빠르게 시작되었다. 이는 서울, 경기도, 마산, 창원, 밀양, 대구 등의 도시지역은 도시화 에 따른 기온상승의 영향인 것으로 해석된다. 이 같은 경향은 2005, 2010년에도 같은 경향으로 보이고 있어 도시화가 식물계절 변화에 중요한 영향을 미치고 있는 것으로 해석할 수 있다. 본 연구의 시간적 규모인 10년 이내에서는 기후변동 에 따른 식물계절 현상의 변이성을 잘 나타내었으며, 이 러한 식물계절 모니터링 기법은 30년 이상의 보다 장기 적인 자료를 축적을 통하여 기후변화 양상에 따른 생물 계절 현상 변화와 해석에 중요한 역할을 할 것으로 생 각된다.

Global climate change has become a major issue which affects the humanity and nature around the world. Caused primarily by human actions of unabated greenhouse gas emission and deforestation, the destructive effects of climate change have become more frequent and intense during the past decades. As climate change is a global problem, addressing its causes and consequences also requires global responses. While climate change is caused by people from various parts of the world, its impacts disproportionately affect people in coastal regions and islands around the world, and marginalized poor communities in developing countries. Everyone in the planet has a role in addressing climate change, but governments, non governmental organizations (NGOs,), and corporations have broader roles and responsibilities. Due to their mission alignments to protect the environment and conserve nature, environmental NGOs play several vital roles in the fightagainst climate change. Environmental NGOs and international NGOs are in a unique position to respond, and to facilitate the involvement of other sectors in mitigation and adaptation strategies for climate change. This article discusses some of the roles and responsibilities of NGOs in addressing climate change.

Recently, peach orchards Plautia stali, Halyomorpha halys, Apolygus spinolae, etc. several species of stink bugs continually damaged. This study using a aggregation pheromone were Riptortus clavatus forecasting investigated at cheongdo, Gyeongsan, Youngchun, etc. gyeongbuk province. As a result, emergence time and population density differences, respectively. The population density of R. pedestris the first time that occur was in mid-April in 2011 and 2012. In March 2013, under the influence of high temperatures in the first occur early April after a temporary increase in the first occur, due to low temperature occur in the early or mid May. Stink bugs leaf damage late April until mid-May increased, while the decrease rainy season increased again in the early August. fruit is severe damaged from mid-May to mid-June and early or mid August. Time period pesticide applications to examine the control effect of stink bugs from 7 a.m. to 7 p.m. separated by four kinds of insecticides treatment. when spray insecticides 7 a.m. the control effect was higher in the treatment group. These results suggest that, stink bugs of the peach fruit through the feeding area, young fruit stage Xanthomonas arboricola pv. pruni and maturation stage Monilia fruticola secondary increased a cause of disease damage.

Rice stem borer, Chilo suppressalis Walker is a significant rice insect pest. A newly hatched larva bores a hole into the rice stem and feeding inside. The damage results in drying and white heads of rice. Climate change will affect pest and its host population dynamics variously. In this study, the degree of asynchrony between emergence of rice stem borer and rice transplanting was examined by their phenology models. Also, correlation was examined between winter mortalities of the rice stem borer and relative humidity categorized by daily minimum temperature in 12 sites throughout the country from 1992 to 2013. The degree of asynchrony appears to be increased in future climate condition. And we found a negative correlation between winter mortality and the relative humidity. Winter mortality will be decreased in the future because of increasing winter minimum temperature and snowfall. We hypothesize that the stem borer may increasingly harbor in alternative hosts such as reed in its first generation and move to rice in the second generation. Currently the simulation study is being conducted to verify this hypothesis.

Based on climate change scenario, local distribution of insect pest population should be changed in near future as well as their host. Even though well defined insect geographical distribution model is developed and projected its potential establishment in Korea under climate change scenario, it has defectiveness without geographical matching of its host. SADIE (spatial analysis with distance indices) allows improved interpretation of the spatial associations between two populations within a given sampling area because it is designed for data that are distributed in discrete areas with relatively well-defined boundaries, and measures the extent of clustering with subsequent testing for spatial patterns in relationships among sample locations. In this study, we calculated and analyzed the spatial association between the Ecoclimatic Index (EI) of light brown apple moth, Epiphyas postvittana, using CLIMEX, and projected farm land suitability of apple trees for the possibility of shift and matching geographical location of insect-host relationship under climate change scenario in Korea.

최근 WMO는 온실가스 배출량 시나리오(SRES)를 대신하여 대표농도경로(RCP)를 바탕으로 새로운 기후변화 시나리오를 생산하였으며 기상연구소는 RCP 시나리오를 바탕으로 한반도의 새로운 기후변화 시나리오를 생산하였다. 본 연구에서는 과거 관측값을 바탕으로 평년(1981-2010)의 애멸구의 우화시기와 세대수를 추정하였으며, RCP 8.5 시나리오를 바탕으로 2020년대(2015-2024), 2050년대(2045-2054)와 2090년대(2085-2094) 애멸구의 우화시기와 세대수를 예측하였다. 평년 애멸구 월동 1세대수의 우화일인 176.0±0.97일과 비교하여 2050년대에서는 13.2±0.18일(162.8±0.91일), 2090년대에는 32.1±0.61일(143.9±1.08일) 앞당겨질 것을 예측되었다. 그리고 애멸구의 연간 세대수는 2050년대에서는 현재보다 2.0±0.02세대, 2090년대에는 5.2±0.06세대 증가할 것으로 예측되었다.

The present study was performed reviewing references determine the infection status of Korean freshwater fishes and relation with climate change of Korean peninsula. The most common infections of Korean freshwater fishes are flatworms (trematodes) and spiny-headed worms (acanthocephalans). Total 61 species of Korean freshwater fishes for infectious disease has been reviewed. Among them, 44 species of freshwater fish belong to Cyprinidae and 17 species for Cobitidae, Siluridae, Bagridae, Amblycipitidae, Synbranchidae, Centropomidae, Odontobutidae, Belontiidae, and Channidae. The Korean freshwater fishes had total 35 kinds of parasite pathogenic organisms (Acanthocephala opsariichthydis, Centrocestus sp., Cyathocotyle sp., Diplostomum orientale, Diplostomum sp., Echinochasmus sp., Echinostoma sp., Genarchopsis sp., Holostephanus metorchis, Metacercaria hasegawai, Metagonimus sp., Metorchis taiwanensis, Neoplagioporus zacconis, Palliolisentis chinanensis, Palliolisentis chunjuensis, Prosorhpynchus sp., Centrocestus armatus, Clonorchis sinensis, Holostephanus nipponicus, Metorchis orientalis, Cyathocotyle orientalis, Pseudexorchis major, Exorchis oviformis, Trachelobdella sinensis, Metagonimus miyata, Isoparorchis hypselobagri, Clinostomum complanatum, Centrocestus asadai, Metagonimus yokogawai, Echinostoma cinetorchis, Echinochasmus japonicus, Diplozoon nipponicum, Metagonimus takahashii, Carassotrema koreanum, and Echinostoma hortense). Maximum infections belonged to Pseudorasbora parva as Cyprinidae had 19 kinds of parasite organisms, including Centrocestus armatus, Clinostomum complanatum, Clinostomum complanatum, Clonorchis sinensis, Cyathocotyle orientalis, Echinochasmus japonicus, Exorchis oviformis, Holostephanus metorchis, Holostephanus nipponicus, Metacercaria hasegawai, Metagonimus yokogawai, Metorchis orientalis, Metorchis taiwanensis, Pseudexorchis major, Cyathocotyle sp., Diplostomum sp., Echinochasmus sp., Metagonimus sp. and Prosorhpynchus sp. Human foodborne trematode infections are an important public health concern in Korea. In the future, under the climatic extremes on Korean peninsula such as floods, drought and temperature variability, in particular, the susceptibility of freshwater fishes to infection will be decreased.

Temperature is one of important factors to determine insect phenology. Based on the bioclimatic law, the relationship between climate change and ecosystem change was studied from 2008 to 2013 in HECRI by monitoring the spring emergence patterns of three Papilionidae species (Papilio xuthus, P. machaon, and Sericinus montela). The overwintering pupae were set on the wood plate and adult emergence were monitored and recorded in every morning. The first spring emergence of P. xuthus, P. machaon and S. montela in 2013 were Apr 19th, May 1st and Apr 22th, respectively. And peak time of three species were May 7th, May 11th and May 9th, respectively. Study on temperature-dependent development was conducted to investigate the temperature effect on adult emergence of overwintering S. montela pupae at four different constant temperatures (15, 20, 25 and 30°C) with photoperiod 10:14(L:D). The low temperature threshold of female, male and both sexes combined were 12.39, 12.16, and 12.37°C, respectively. Developmental period of overwintering pupae to adults decreased with increasing temperature from 15 to 30°C. Thermal constant of female, male and both sexes combined were 220.26, 192.31, and 200.18DD, respectively. The relationship between thermal constant and cumulative adult emergence was predicted by temperature-dependent development. Estimate through 7 times on the highest temperature was equal and results were distinctively divided into two pattern(2008～2010 and 2011～2013). The relationship between observed and estimated values was presented by linear regression (r2=0.97)

With over 7 billion people on the planet, agriculture faces immense pressure to meet global demands for food. One third of consumed food relies on insect pollination with by far, the predominate pollinator being the honey bee, Apis mellifera. Although future challenges facing agriculture will come from multiple domains, one of the immediate challenges is honey bee decline. Stress associated with transportation, pesticide exposure nutritional limitations, various diseases and pests have all been recognized as potential factors in honey bee decline. With the prospect of future global changes in climate, honey bees will also face changes in forage availability and overwintering potential. At the level of the individual colony, research has shown that honey bee health is directly correlated to genetic diversity. Increased colony diversity is associated with lower disease intensity, increased disease resistance, greater workforce productivity and thermoregulation stability. Genetic diversity at the population level serves as the raw material for selective breeding in agriculturally important plants and animals, including the honey bee. Honey bees are not native to Korea, however, and importation and founder events associated with the establishment of honey bees represent a series of genetic bottlenecks that limits the diversity of introduced honey bee populations. Fortunately, Apis mellifera consists of around 28 recognized subspecies within its native range, each with specific adaptations to climatic selective pressures endemic to its own location. Climate change is expected to be bring a high degree of uncertainty in the future to climate expression in various locations. Fortunately, the honey bee has a wide breadth of diversity contained within various subspecies and careful importation and evaluation of specific stocks may be highly useful as we enter climate uncertainty in the future. With the recognition that agro-ecosystems are highly interconnected and multifaceted, one of the greatest challenges facing agriculture is preserving and improving honey bee health.
