Outline of Final Research Achievements

This research focused on the functions and importance of resprouting from trees that are not seriously damaged. More than 700 resprouts in 60 plots in a forest landscape with a relatively large range in elevation (ca. 1,000 m) were tagged and their demographic processes were recorded. The functional traits of the target species and environmental conditions of the plots were measured to investigate the evolutionary tradeoffs between resprouting and the traits, and responses of resprouting to the environmental conditions. Using these data, we analyzed the number of resprouts per stems, and clarified the indirect causal relationship between resprouting and dominance in forests, the resprouting responses to environmental conditions, and the effect of functional traits on resprouting.

Academic Significance and Societal Importance of the Research Achievements

従来の萌芽に関する研究の多くは,損傷を受けた状況を対象にしており,大きな損傷を受けない状況における萌芽発生に関する知見は,少数の種に限られている。しかし,大きな損傷を受けない状況における萌芽発生も珍しくはない。本研究は,大きな損傷を受けない状況における萌芽発生に焦点を当て,多くの樹種で観察を行い,1)萌芽を持つことと森林で優占することとの関係, 2)個体状況や環境条件の影響,3)機能形質と萌芽との関係を解明した。得られた知見は,樹木の適応や森林動態を総合的に理解するための不可欠な構成要素となる。
