    Spartina alterniflora introduced worldwide has impacted local Japanese ecosystems. Then the management methods of the species are seriously required. In 2019, the invasion of the species was reported at Aichi Prefecture, Japan. The vegetation of the species was grown up to 449 m2 for 5 years. However, the relationship between the habitation of the species and environmental factors remains unclear. Therefore, we made a habitat prediction model using GLM (general linear model) to define the environment of the S. alterniflora habitat of Aichi Pref., incorporating data in 2019. That measured population density, location, ignition loss of physical environmental data, pH, NaCl concentration and altitude over the sea level by us. Our analysis showed that the standardization parameter altitude over the sea level was the main effect in the predictive model (estimate 4.158) and had the greatest absolute value. And the Wald value is significantly large (42.426). Secondary the reciprocal relationship expression between the altitude and pH was high value, 1.007. The species likes the habitat that altitude is high and pH is 7.1-7.3. For the GLM, we made the distribution for the species, the reappearance is well done. Then the avoidance of the species expansion, the bank of the tidal area should erase the higher riverbed

    The habitat of riverbank dune nurses several endangered species. Why did this area maintaine endangered species despite of invasion of alien species? Then growth of an endangered species (Fimbristylis sericea) and an alien species (Diodia teres) was studied in a greenhouse experiment in which the species were grown alone or together and the resultant effects of shoot and root competition were assessed. In the alone growth experiment, the survival rates of the both species were same. In the shoot competition experiment, the D. teres reduced growth rate of F. sericea. In the root competition experiment, the F. sericea reduced growth rate of D. teres. In the total competition, F. sericea were superior to D. teres. From the experiments, F. sericea was more competitive than D. teres under the waterless same habitat. D. teres was more competitive than F. sericea under the waterrich condition. The habitat of riverbank dune is always affected strong wind, than the disturbance of sand moving. When D. teres is grown up, the sand moving prevented growth of D. teres. In the long term, the vegetation succession will reduce the disturbance frequency and will be occurred the extinction of endangered species.

  • INFLUENCE OF LIGHT ON MICROBIAL RIVER WATER ECOSYSTEM AND ITS SELF-PURIFICATION POTENTIAL Reviewed International journal

    Self-purification at rivers is mainly conducted by microorganisms attached on river bed. In order to enhance
    the self-purification capacity, several process or technologies have been proposed for improvement of river water
    quality and preservation of bio-diversity. From the viewpoints of environmental engineering, finding influential
    parameters and their effective control are effective to improve river water quality. However, there are a lot of
    parameters affecting self-purification capacity at rivers, and quantitative evaluation of these parameters have not
    been completed. In this study, influence of light on both microbial river water ecosystem and its self-purification
    capacity are investigated. There are several type of water purification facilities incorporated in rivers in order to
    improve river water quality and maintain bio-diversity. Most of the cases, light (sun light) is not blocked, and the
    light might affect microbial community and structure by photo synthesis.
    Lab-scale experimental facilities (artificial river) are set, and artificial contaminated river water are introduced
    to the system. Light irradiation stimulates algal activity and affects the composition of the other microorganisms
    such as bacteria and zooplankton. By mass balance analysis of carbon, it is made clear that amount of organic
    carbon accumulated in the river under lighting condition becomes almost double compared with the case under
    dark condition. It is suggested that clean river water condition can be affected by light more than contaminated
    river water condition because of the large relative intensity of organic carbon loading by photo synthesis.

    The C. japonica is an ecologically important species in estuaries and brackish waters, as well as a very important fishery resource. However, the relationship between its habitation conditions and environmental factors remains unclear. We therefore made a habitat prediction model using GLM to define the environment of the C. japonica habitat of Lake Shinji, incorporating data acquired from 1982 through 1983 which measured population density, location, silt/clay content, ignition of physical environmental data, pH, dissolved O2 density, chloride ion concentration, and COD of the quality of the water. Our analysis showed that the standardization parameter ignition loss, measuring organic matter and carbonate content in the sediment, was the main effect in the predictive model (estimate -2.22) and had the greatest absolute value. Thus the C. japonica's distribution is dependent on ignition loss, in the predictive model. As for interaction terms modifying distribution, the dissolved O2 and silt/clay content ratio had the largest absolute value at -2.12. In addition, it was revealed that the environmental factors which limit population levels of the C. japonica every season are different. These results, while derived from C. japonica, also suggest that our GLM model is effective to more fully understand the habitation area of immobile benthoses in general.

    It has been pointed out that the vegetation succession brings out the reduction of the Luehdorifia japonica. But some researcher insisted that thinning cannot increase the population of the butterfly. Then we cut down half of the forest and reverse succession, in order to study the influence of the population of Asarum rigescens var. brachypodion, larval food plant, and the mass of reward of the butterfly by cut off the forest. It was being thought that thinning in a forest obstructed growth of forest floor plant, but the growth of A. rigescens that was famous of forest floor plants, was promoted. On the other hands, A. rigescens did not grow up in the climax forest despite of survive. In the green house experiment we can get the proof of the growth condition. The growth of open light condition was superior to that of the 40% light penetration condition. And more the number of flowering of plants was more increased than ever. It was indicated that the thinning in a forest is important for the habitat of the symbolic butterfly, L. japonica, and it increased other plants bloom, and to secure source of nutrition of much insect kinds

    自然環境は放置すると遷移がすすみ、裸地から森林へと変化する。このため、各遷移段階において特徴的な種は失われ極相群落へと変化する。尾張丘陵地帯では層状の粘土層が滑ることによって頻繁に裸地が形成されることにより、湿地が維持されてきた。しかし、近年の開発により土地が滑ることがなくなり湿地が消失してきた。そこで本研究では湿地を再生するべく伐採などの効果を調査した。その結果、森林伐採が蒸散量を抑え湿地を復元するのに有効であることが示された。
