Outline of Final Research Achievements

Flora adapting to heavy snow environments is distributed along the Japan Sea in central Japan. However, formation process of heavy snow environments and floras endemic to areas along the Japan Sea have not been clarified. This study conducted analysis of macrofossil and pollen from the lower Pleistocene in south Niigata Prefecture and compared the results with plant fossil data from areas along the Pacific Ocean. Plant fossil evidences form the south Niigata indicate that assemblage composition changes occurred, corresponding with climate changes between 2.5 and 0.7 Ma. Differentiation of flora between Japan Sea and Pacific Ocean sides possibly began in 1.4 -1.3 Ma, indicating by extirpation of floras endemic to the Pacific side areas. Plant molecular analysis indicates genetic divergence corresponding with climatic difference between Japan Sea and Pacific Ocean side areas.

Academic Significance and Societal Importance of the Research Achievements

本研究で大型植物化石に基づいて明らかにした,約250~70万年前の第四紀(約260 万年前以降)の大半を占める時代の気候変動に対応したフロラの変化記録は,この時代の植物化石記録としては世界的に見ても最も詳細なものである.地史イベントに伴う多雪化という環境変化への生物学的応答についての研究成果は,森林の管理にも応用可能な,生物多様性形成過程と地球環境変化への植物群の適応の歴史に関する新たな知見となる.
