| 6. | KUME, Atsushi, Publishing research when English is your second language, Wiley Research APAC Webinars, 2020.08, Today, the percentage of researchers whose second language is English is higher than that of researchers whose first language is English. As a result, a new language, SCIENTIFIC ENGLISH, is emerging. In this language system, complicated phrases and syntax are excluded, and simple and easy-to-understand expressions are selected. This webinar will cover practical techniques for creating English-language papers that can be submitted to international journals for researchers whose second language is English. Among researchers whose second language is English, there are researchers whose first scientific language is English and researchers whose second scientific language is English. For example, Japanese scientists often go through the process of learning and systematizing science in Japanese and translating it into English. Today, the ability of web-based translation systems has been greatly improved, and machine translation of SCIENTIFIC ENGLISH has reached a practical level. At this time, writing in the first language that is easy to translate is the key to improving the accuracy of machine translation. By asking a skilled human English editor to review such drafts, the manuscript writing efficiency and quality can be improved.. |

Therefore, it is not easy to distinguish the role of Gravity of the plant growth from other mechanical stresses. The creation of an altered gravity environment is essential for analyzing plant responses to increases in gravity. Hypergravity environments produced by centrifugation have provided a practical experimental system for angiosperms. However, these experiments were often performed under dark conditions with strong hypergravity (>30×g). Such experiments intended to reveal the effects of short and transient stress, rather than continuous stress, and did not include the process of photosynthesis. However, for a long term plant cultivation experiments, dynamic maintenance of gas-exchange process accompanying photosynthesis is one of the important matters in plant cultivation. The transport of gaseous molecules into and out of the leaf is largely driven by buoyancy, and both the force of gravity and the amount of supplied energy are main determinants. We quantified changes in plant growth and photosynthesis in the model plant of mosses, Physcomitrella patens, grown under a hypergravity environment for several 8 weeks using a custom-built centrifuge equipped with a lighting system. We found that the hypergravity treatments increased the growth rates of colonies as well as rhizoid length. In a canopy of P. patens, the area-based photosynthesis rate was increased. These results suggest that changes in gravity are important environmental stimuli to induce changes in plant growth and photosynthesis by P. patens, in which an alteration in chloroplast size is one of the key traits. . |

| 22. | Ken'ichi Shinozuka, Masaaki Chiwa, Ichiro Tayasu, Chikage Yoshimizu, Atsushi Kume, Topographic impacts on downstream NO3- reduction with high levels of NO3- leaching from upland forests, Japan Geoscience Union Meeting 2016, 2016.05, [URL], Non-point source nutrients, such as excess fertilizers from agriculture and human sewage water, are main cause of eutrophication of lakes, streams, and coastal areas. The upstream areas of suburbs of Fukuoka are covered with nitrogen-saturated forests, and supplied high concentration NO3 - river water to the downstream. Such nitrogen-saturated forests have large impact on the downstream water quality (Chiwa et al., 2012), but less information was available of the mechanism of the changes in NO3- concentration from upstream to the downstream. The objectives of this study were to clarify (1) whether the nitrogen dynamics (the concentration of NO3-, δ15NNO3 and δ18ONO3) in the downstream were affected by the nitrogen-saturated forests in the upstream, (2) the influence of nitrogen runoff from agriculture and urban area in the downstream, and (3) the influence of the river gradient on denitrification. NO3- concentration and the stable isotopes, δ15NNO3 and δ18ONO3 were measured in the Tatara River Basin, located in northern Kyushu, western Japan. Water samples were mainly collected from branch rivers; Ino River, Sue River and Umi River. Deciduous mature forest dominates the ridges in the upstream, with paddy, farmland and urban dominating in the middle and downstream. Topographic Index (TI) was calculated by using Digital Elevation Model (DEM) with ArcGIS software. Our results showed that the NO3 - concentration in the upstream of three rivers (33.9-82.8 μmol/L) were higher than the other non-saturated forests. Lower δ18ONO3, higher NO3 - and δ15NNO3 in the downstream were be found in Sue River and Umi River. On the other hand, Ino River showed different trend that lower NO3- concentration, higher δ15NNO3 and δ18ONO3 concentration in the downstream. The higher NO3- concentration in the downstream in Sue River and Umi River was affected by the increasing agriculture and urban areas in the downstream. However, the NO3- concentration in the downstream of Ino River decreased with the increasing agriculture and urban areas. The average TI value showed no difference between rivers. However, the distribution of TI values in Ino River was different from other rivers. Ino River has smaller changes in gradient from upstream to downstream and fewer agriculture and urban areas in the downstream than the other two rivers. These differences could result in the higher probability of denitrification occurring and the lower NO3- loading in the downstream in Ino river. The nitrogen-saturated upstream forests in this watershed has large impact on the nitrogen sources to the downstream. In the areas with steeper gradient, the high concentration of nitrogen runoff was supplied to the agriculture and urban areas. On the other hand, in those areas with gentle gradient, the nitrogen loading in the downstream also decreased due to the gentle gradient of the watershed and it was suggested that the rate of denitrification and decrease NO3- concentration in the downstream was also high.. |
| 23. | 久米 篤, The importance of physiochemical reactions on leaf surfaces to understand the effects of various air pollutants, ACAPセミナー, 2015.02, A dense vegetation cover (canopy) intercepts a large proportion of bulk deposition and also efficiently captures fog precipitation. Under such conditions, most of the rain and fog deposition falls on the surface of canopy, not directly on the soil surface. Chemical properties of the water droplets are changed when they pass through the canopy. The accumulated dry deposition on the canopy surfaces is washed out by rain and fog, and several water-soluble plant nutrients are leached out from the leaf surfaces. Usually, K+, Mg2+, Ca2+ and other cations are leached from internal plant tissues. NO3-, NH4+ and other solutes, gases and particles are taken from leaf surfaces. Basically, dry and wet deposition is the main nutrient source of Japanese forest ecosystems. However, sometimes the interactions between leaf surface processes and deposition have harmful effects on the plant growth. High concentration of H2O2 in the fog and dew water is frequently observed in the forest areas and it may cause negative effects on the photosynthesis as similar as gaseous Ozone. Excessive leaching causes nutrient deficit and excessive deposition causes various disorders of plant growth. The physiological processes on leaf surfaces are important to understand the effects of air pollution on the Japanese forest ecosystem.. |

In order to see longer-term effect of hypergravity on the development of plant shoots, however, it is necessary to carry out the experiments in the light. In the present study, we have set up a centrifuge equipped with lighting system, which supports long-term plant growth under hypergravity condition, in order to see long-term effects of hypergravity on the development of vascular tissues of inflorescence stems. Arabidopsis plants (Arabidopsis thaliana (L.) Heynh., Col-0), which were grown under 1 G conditions for 20-23 days and having the first visible flower bud, i.e., at Arabidopsis growth stage number 5 (according to Boys et al., 2001), were selected as the plant material. These plants were exposed to hypergravity stimulus at 10 G in a direction from the shoot to root for 10 days in the continuous light. Effects of hypergravity on growth of inflorescence stems, lignin content, and morphometrical parameters of the stem tissues were examined. As a result, the length of the inflorescence stem was decreased. Cross sectional area as well as cell number, and lignin content in the stem were increased under hypergravity. The length of basal internodes of the stem was decreased under hypergravity. In conclusion, the inflorescence stem was suggested to be strengthened through changes in its morphological characteristics as well as lignin deposition under long-term hypergravity conditions.. |

| 30. | Yoshitoshi Uehara, Atsushi Kume, Takanori Nakano, Distribution of Sr isotope ratios in the vegetation of Siberian dwarf pine at Mt. Tateyama, JpGU Meeting 2013, 2013.05, Chubu-Sangaku mountainous area in central Japan is composed of mountains whose elevation is over 2500 m above sea level (a.s.l.). In the soil of this high elevation area, biological activity is inactive due to low air temperature and long snow cover, resulting in the slow decay of biomass, immobilization of nutrient, and depressing the material circulation. Wet and dry depositions in these mountainous ecosystems play an important role as nutrient supply. Wet precipitation on the forest ecological system partly adheres on leaves and branches, and water returns to the atmosphere by evaporation. The chemical composition of throughfall changes from the precipitation by interaction with tree and grass. Some elements are absorbed from crown. Further high elevation area is sensitive to materials transported from regional air pollution. However, there are a few geochemical and material-circulation studies on the mountainous ecosystem with high elevation.We have been studied ecological and plant physiological studies on Mt. Tateyama, one representative Chubu-Sangaku mountainous area. The ecological system of Mt. Tateyama is important, since this mountain is strongly impacted from air-pollutants from the Asian continen as it faces the Sea of Japan, and is affected by global warming as the air temperature increases more than three times as the world average during recent 30 years. Sr is known as a powerful hydrological and ecological tracer but it is utilized as a fingerprint to understand plant physiology. This isotope is unique as it can quantitatively discriminate atmosphere-derived Sr from bedrock-derived Sr. In order to elucidate the material circulation system on the forest ecosystem in Tateyama, we sampled a variety of water (rainfall, throughfall, fog water, snow, groundwater, and dale water) and Siberian dwarf pine in Joudodaira, and determined their Sr isotope ratios. Our result shows that the 87Sr/86Sr ratio of groundwater (0.7068) and dale water (0.7070) are almost identical to that of soil and bed rock (0.7070), suggesting that Sr in the surface and ground water is largely derived bedrock through chemical weathering. This is consistent with that rainwater (0.7091) and fogwater (0.7090) have higher 87Sr/86Sr ratios. As this ratio is similar to seawater value (0.7092), Sr in precipitation is largely of sea-salt origin. It is notable that the 87Sr/86Sr ratio of dirty materials in snow is variable from 0.7095 to 0.7198. This high ratio suggests an incorporation of Asian dust particle whose 87Sr/86Sr ratio is around 0.720. The 87Sr/86Sr ratio of throughfall is 0.7094, indicating a contribution Asian dust Sr. The most notable feature is that Siberian dwarf pine (Pinus pumila) has high 87Sr/86Sr ratios (0.7099 in leaf and branch and 0.7097 in litter). Most alpine plants have lower 87Sr/86Sr ratios (0.707 of Gaultheria miqueliana and 0.708-0.7095 of others). This result demonstrates that Siberian dwarf pine is actively absorbing Asian dust particles.. |
