Outline of Final Research Achievements

The aim of this study is to evaluate the effects of oak wilt disease (OWD) on fungal community and decomposition of dead stems of Quercus serrata. We selected seven forest stand along latitudinal gradient in Japan to monitor decomposition of newly felled logs of Q. serrata. Metabarcoding of fungal DNA ITS region obtained from newly felled stems showed a positive correlation between fungal specie richness and annual temperature or annual precipitation in forest sites suffered by OWD. However, the correlation was not present in the stand with out OWD. Across the 5-year study period, we obtained substantial data and samples to analyze the long-term effects of OWD on fungal community and wood decomposition.

Academic Significance and Societal Importance of the Research Achievements

樹木の大量枯死は、森林からの二酸化炭素放出量を増やし、森林を炭素のシンクからソースへと変えてしまうと考えられている。しかし、大量枯死は森林の環境も激変させるため、枯死木の分解やそれに関わる菌類群集の機能にも影響を与える可能性がある。本研究により、ナラ枯れで枯死したコナラの丸太には、人間が伐倒した丸太とは有意に異なる菌類群集が発達することが明らかになった。分解のモニタリングを継続し、菌類の分解機能との関係を詳細に調べていくことにより、ナラ枯れが森林の炭素貯留に与える影響をより正確に評価することができる。
