| Outline of Final Research Achievements |
The ecosystem of the subalpine and alpine zones is vulnerable to climate changes such as global warming. Bryophytes can be useful indicators of vulnerability, because they are sensitive to their surrounding environments. In this study, we examined an effective method of using bryophytes as bio-indicators to evaluate the vulnerability of subalpine and alpine ecosystems. The study site was the Yatsugatake Mountains in the central part of Japan. We examined changes in the bryophyte diversity along an altitudinal gradient as well as response of bryophytes to temperature increase by conducting experiments at different temperatures. On the basis of the results, we identified the bryophyte species that are useful indicators and sensitive to climate changes. We, further, proposed an ecosystem monitoring system for the subalpine and alpine zones. Our study results can contribute to the conservation of ecosystems in subalpine and alpine zones.
