Research theme †
- Interactive effects of rising aerial ozone (O3) and carbon dioxide (CO2) concentrations on deciduous tree species
Saplings of birch species which are native to Hokkaido (Japan) and a larch species which is widely planted in Hokkaido are being exposed to elevated concentrations of O3 and/or CO2 in open-top chambers.
I do the research through tree-physiological approaches (photosynthesis, phenology, anatomy) helped by the members.
