    We constructed an empirical model in which the rates of gross primary production (GPP) and ecosystem respiration (R_<eco>) were calculated using meteorological, soil and plant variables, based on our previous measurements of carbon dioxide (CO_2) fluxes using a closed-chamber technique in Mongolian grasslands. In the previous studies, we determined GPP and R_<eco> using transparent and opaque chambers and simultaneously measured the environmental variables inside and beside the chambers. These measurements allowed us to quantify direct and accurate relationships between the rates of GPP and R_<eco> and their controlling factors. The GPP, R_<eco> and their difference net ecosystem CO_2 exchange (NEE) were computed in a semiarid grassland site of Mongolia for the growing seasons of 2010 and 2011 using observed values of photo-synthetically active radiation, air and soil temperatures, vapor pressure deficit, soil water content and estimated values of aboveground biomass from a remotely sensed vegetation index. Model performance was validated by comparing the modeled and observed NEE values using an eddy covariance technique. Results showed that the model successfully reproduced the magnitude and seasonal variations of the observed NEE, and regression analysis showed reasonable agreement in both years. Cumulative rates of GPP and R_<eco> during the plant-growing season (May - September) were 200.3 and 210.5 g carbon (C) m^<-2> in the dry year (2010) and 342.3 and 300.1 g C m^<-2> in the wet year (2011), respectively. This result indicates that drought was more effective in reducing CO_2 uptake by the plant than in reducing ecosystem respiration. Consequently, the grassland ecosystem was a net carbon source during the growing season in 2010 and a net carbon sink in 2011.

    Recently, the number of forest fires in West Siberian Lowland (WSL) is increasing and they are considered as one of the main driving factors influencing carbon cycling in whole earth. Since many forest fires take place in large and hardly accessible areas, remote sensing seems to be the most appropriate tool for creating forest fire recovering history. In this paper, SPOT HRV and Landsat ETM images were used to highlight the damaged area by fire that occurred in the summer of 1998. The damaged area was extracted by using principal component analysis supplemented by ground truth data. The total burnt area was calculated to be 13.8 (km2). Then re-generation condition in burnt area from 1995 to 2002 was investigated using NOAA AVHRR data with sub-pixel land cover characterization. We demonstrate that the phenomena observed by remote sensing data is consistent with climatic data including daily precipitation and temperature. The method proposed in this study can be an effective way for forest recovering monitoring.

    Diurnal variation in CO2 flux from the soil was measured by a closed chamber technique at a developed land site in Tokyo from September to November in 1999. The measurements were made four times for 24-h periods at two fixed sites where there was no plant cover (A) and where Miscanthus sinensis was dominant (B). CO2 fluxes averaged 98.2mg CO2 m-2h-1 at the site A and 184.3mg CO2 m-2h-1 at the site B. The fluxes from both sites showed a clear diurnal variation, which was high during the day and low at night. The temporal variation was highly correlated with the air and soil temperatures, especially at depths of 1 and 5cm. The relationship between CO2 flux and temperature was exponential. The CO2 flux increased exponentially 1.99 times when the soil temperature at 1cm deep increased by 10°C.

    The objective of this study is to estimate the response of the permafrost at the Daisetsu Mountains, central Hokkaido to a continuous climatic change. A one-dimensional, nonsteady state, heat conduction model with phase change is used to calculate the change of permafrost thickness during the last 20, 000 years. The result of simulation shows that the permafrost responded quickly to the surface temperature change and it has remained without thaw since the Last Glacial Maximum. The minimum permafrost thickness is estimated at 11.5 m at about 5 kyr B. P. and reached to 30.1 m at present. The simulation also indicates that the permafrost thickness is sensitive to soil water content and ground heat flow.

    モンゴルの草原地帯に生息する長距離移動性の野生草食獣モウコガゼルの大移動の保全にむけて、動物装着カメラ映像の通年記録による、同種他個体や家畜の影響評価手法の開発を進めている。新型コロナ感染症とウクライナ戦争の影響により、研究初年度と2年目に予定していた、モンゴルでの首輪装着によるモウコガゼルの個体追跡と映像等の記録が開始できなかったが、2023年9-10月にモウコガゼル分布域の北部と南部の2地域で、合計28頭のモウコガゼルの捕獲と首輪装着に成功した。これにより、モウコガゼルや家畜の密度、植生などが異なる地域での家畜との遭遇頻度や行動などの比較が可能になることが期待される。本調査時には、過去の課題で追跡した個体の首輪の回収と加速度データのダウンロードにも成功し、国内ではこれらのデータの解析を進めた。
    加速度解析では、静的活動と動的活動からなる数時間単位の活動周期の季節変化傾向がすべての個体で一致していることが確認された。地域差や同一個体での年変動も観察された。また、3軸の加速度解析から、飛来性の昆虫を除けるためとみられる特徴的な首振り行動を検出する手法を確立し、首振り回数が、飛来性昆虫の活動が活発だと推測される季節や時間帯と正の相関があることを明らかにした。飛来性昆虫は、有蹄類の移動や生息地選択、栄養状態などに影響を及ぼすことが知られている。観察が難しい野生動物での、定量的・継続的な飛来性昆虫の影響評価手法の確立は、野生有蹄類の移動生態研究の発展につながるだろう。また、睡眠(首を倒した状態での休息)の判別手法も確立した。さらに、近距離であれば雌雄判別も可能な、首輪カメラで撮影された動画からの機械学習を用いた高精度での他個体検出手法を確立した。

    The nature-society system in drylands is among the most vulnerable to projected increasing frequency of various extreme weathers. Especially, drylands in middle-high latitudes have a severe environment coupled with an arid and cold climate and the livelihood has been jeopardized repeatedly by natural disasters that occur in such a climate. The disasters are characterized by so-called 4D (i.e., drought, dzud, dust storm, and desertification) that occur interactively. However, previous approaches towards elucidating disaster mechanisms and implementing the management have not fully been integrated, as they only dealt with each disaster separately.
    Given this background, the present project aimed (1) to relate the 4D disasters in dry Eurasia to each other in terms of causal mechanisms (especially, drought memory) and the time scales of their occurrence and (2) to develop comprehensive proactive countermeasures and make a policy recommendation for mitigating multi-disaster impacts.

    Recently, there has been a worldwide trend for intensified drought. Furthermore, in general, projections of climate models have suggested that the frequency and intensity of extreme weathers including droughts will likely increase in the future. Given this background, the present study investigated a series of mechanism of how meteorological drought (below-normal precipitation) affects soil moisture, vegetation and animals and made an assessment of vulnerability of the steppe vegetation in terms of sensitivity and resilience to drought.

    In Mongolia,grassland covers approximately 80% of the country and comprises a major part of East Asian grasslands. The plants live in a semi-arid climate,and have often suffered from droughts.Global climate models predict that future increases in atmospheric carbon dioxide (CO2) will cause significant drying in this region during summer,caused by increased temperature and potential evaporation. Studies have indicated that the grasslands respond sensitively to changes in climate,particularly to changes in precipitation. The objective of this study was to evaluate the quantitative dependence of photosynthetic production and ecosystem respiration on temperature,moisture,radiation,and plant biomass in a semi-arid grassland. Toward this aim,we measured CO2 fluxes using a dosed-chamber technique in a grassland in Mongolia and in an environmental control equipment in Tottori University. As a result,we found that (1) values of gross primary production (GPP) were linearly related to live aboveground biomass (AGB) enclosed by the chamber, (2) GPP/AGB fit well a rectangular hyperbolic light-response curve for all the study periods,but when the air and soil were dry,considerable reduction in GPP was observed, (3) the GPP/AGB ratio was also expressed as individual functions of air temperature,vapor pressure deficit,and volumetric soil water content,and (4) values of Reco were expressed well as a bivariate function of soil temperature and soil moisture near the soil surface.

    Recently, droughts have become widespread in the Northern Hemisphere continent, having a substantial effect on Mongolian grasslands in the quantitative (such as biomass) and qualitative (such as phenology) aspects. In order to investigate the ecosystem response to such a drought, an artificial drought experiment (DREX) with a rainout shelter was conducted at Bayan Unjuul (105.95°E, 47.04°N) in the typical steppe region during the growing summer rainy season of 2005. The present drought experiment is the first attempt in the Asian dryland. Results showed that the drought manipulation with a dry spell that occurs statistically once in half-one century resulted in drastic reductions in aboveground biomass (AGB), soil moisture, soil organic carbon, and total nitrogen, but not in a significant reduction in underground biomass (UGB). This drought impact was followed by a quick recovery in the AGB in the late summer of 2006, likely on the basis of the UGB having a biomass several times as much as the AGB. However, the drought-sensitive species, soil organic carbon, and total nitrogen have not yet revealed recovery as prior to the drought, suggesting the different time scales of responses for each ecosystem element.

    大気中に存在するメタンガスは二酸化炭素に次ぐ温室効果気体であり、その濃度変化は地球の気候変動に大きな影響を与える。通常、湿地のような湿潤な土壌はメタンガスの放出源となっているが、研究代表者が過去に西シベリアの湿地で観測を行った際に、ゼニゴケで覆われている土壌においてだけは大気中のメタンが土壌に吸収されるという特質を発見した。本研究は日本にも広く分布するゼニゴケにも同様の性質があるのかどうか明らかにすることを、またそのメカニズムを解明することを目的とする。
    通年の野外観測を実施した結果、ゼニゴケ被覆面によるメタン吸収は場所によって大きく異なり、土壌が非常に湿潤な場合にのみメタン吸収が起こっていることが明らかになった。日本におけるゼニゴケの生育場所は、畑の縁辺部や民家の軒先など比較的湿潤ではあっても常時湛水していることは少なく、メタン吸収が起こるのは梅雨期など降水量の多い時期に限られることも分かった。このため、通年で見たときの自然状態でのメタン吸収能は比較的低いと結論付けることができる。メタン吸収のメカニズムを明らかにするため、野外観測と並行して室内実験も行った。実験では、ゼニゴケによるメタン吸収はメタン酸化菌による酸化反応ではなく、ヒドロキシルラジカルの化学反応によるものと示唆される結果が得られた。
    今年度は、本研究のきっかけとなった西シベリアでの観測結果をまとめた論文が、Soil Science and Plant Nutritionに掲載され、また現地観測の結果を中心とした学会発表を行った。

    This research aims at collecting and data-basing old meteorological instrumental data in early 19th century during which no official instrumental data were available in Japan, and the purpose of this research is to clarify the climatic variations in the final stage of Little Ice Age based on our database. Most of the previous studies which discuss the recent climatic variations use official meteorological records by Japan Meteorological Agency, which could get back to 1880's at the earliest.
    However, in global scale, there have been many studies which pointed out the rapid warming occurred at around 1850's and 1860's based on the instrumental data in Europe and North America. In our research project, we also found evidences for cooling in the 1830's and warming in the 1850's. These results indicate good agreement with those previous studies in European countries.
