    A simple method to estimate the rate of the bamboo expansion based on one-time measurement of spatial distribution of culms

    Moso bamboo (Phyllostachys edulis) groves have been expanding in Japanese forests, thus an assessment of the rate of bamboo grove expansion is a critical issue. Previous studies used time-series data which span t...

    Decades-long effects of high CO2 concentration on soil nitrogen dynamics at a natural CO2 spring

    The effects of high atmospheric CO2 concentration ([CO2]) on ecosystem processes have been explored using temporal facilities such as open-top-chambers and free-air CO2 enrichment. However, the effects of high [C...

    Effect of elevated CO2 levels on leaf starch, nitrogen and photosynthesis of plants growing at three natural CO2 springs in Japan

    Plant communities around natural CO2 springs have been exposed to elevated CO2 levels over many generations and give us a unique opportunity to investigate the effects of long-term elevated CO2 levels on wild pla...

    Plant responses to elevated CO2 concentration at different scales: leaf, whole plant, canopy, and population

    Elevated CO2 enhances photosynthesis and growth of plants, but the enhancement is strongly influenced by the availability of nitrogen. In this article, we summarise our studies on plant responses to elevated CO2....
