We utilize tree rings for estimation of changes in radial growth to future climate changes. We can also reconstruct past climate changes using dendroclimatologicaltechniques.CDWood anatomy and formationWe focused on tree ring structures such as density, cell dimensions. Observations on seasonal radial growth and stable isotopes in annual rings can provide good information for understanding wood formation and environmental changes.髄樹皮180017701780179010 mmStudy sites in circum-polarClarification of radial growth mechanisms by anatomical observation and stable isotope tracing experiment.Dendroecological studies at various sites among Japan and circumpolar region.
