Profile 【 display / non-display

  • The ultimate goal of my research is to apply scientific knowledge toward ecosystem-based management and conservation under environmental change. Recently, I am particularly interested in the consequences of realistic loss of biodiversity on ecosystem functioning and services. Field observations and experiments (mainly in arid/semi-arid ecosystems and alpine/subalpine ecosystems), simulation techniques, and analyses of large empirical datasets are in my toolbox.

  • Influences of climatic change on distribution and population dynamics of a subalpine coniferous forest in Hakkoda Mountains, northern Japan.

    Language:English Book type:Scholarly book

    Recent research in the Hakkoda Mountains has shown that climate change during recent decades has caused a shift in the distribution of subalpine coniferous forest, which is dominated by Abies mariesii. To examine this shift, we analyzed past and present aerial photographs and found population dynamics evidence that suggests a shift of this species' distribution to higher elevations. A fine-scale habitat suitability model for the species elucidated the environmental conditions that determine its present distribution, and this model can be applied to predict the future distribution under the predicted warming scenarios. The model showed that not only temperature but also topography and snow deposition will regulate the future distribution. One important suggestion is that habitats at the periphery of moorlands will act as refugia for A. mariesii during the warming process. The fine-scale habitat model may therefore guide the management by providing a measure of how populations will adapt to environmental change.
