| Outline of Final Research Achievements |
Temperatures of areas around wind-holes are maintained to be very low even in summer. Therefore, plant species, which normally occurs in area at more high latitude or altitude, are uniquely found near wind-holes.
It is generally considered that such unique plants (hereafter, wind-hole plants) once widely spread in the Japanese Archipelago during past colder ages but retreated to high latitude or altitude area although some populations near wind-holes are maintained after climate warming after the last glacier era. Thus, wind-hole areas may be refugia for wind-hole plants.
In this study, the genetic differentiation between populations near wind-hole areas and in higher latitude/altitude areas in wind-hole plants were examined using molecular genetic markers to test the hypothesis above. There was no distinct difference in genetic constitution between wind-hole area populations and higher latitude/altitude ones, suggesting that wind-hole area may not be refugia for wind-hole plants.
