Outline of Final Research Achievements

In Japan, grasslands have been greatly declined since their economic merits diminished. Organisms dependent on grasslands are also decreasing accordingly. We visited >70 remnant grasslands in Japan, and collected genetic samples of eight grassland plant (herb) species. We then read the gene sequences of four grassland specialist species among them; coalescent simulation suggests that these species have maintained or expanded their population sizes during recent several tens of thousand years at the national scale.
