Observations on seasonal radial growth and stable isotopes in annual rings can provide good information for understanding wood formation and environmental changes.Ecology, phytogeography, taxonomy of wild plantsUtilization and evaluation of wild resource plantsEcology of wild birds related to vegetation recovery, agronomy and silvicultureCreation, conservation and management of biotopeStatistics for field science, especially for vegetation, ecological succession, and plant morphologyTree ring is an indicator of responses of trees to environmental changes. We utilize tree rings for estimation of changes in radial growth to future climate changes. We can also reconstruct past climate changes using dendroclimatologicaltechniques.Herbarium specimens managed in our laboratorySamples of edible and medicinal fruits (left)Vegetation survey by students (right) TeruoARASEAssociateProfessor,Ph.D.,CuratorKoh YASUEAssociate Professor, Ph.D.Tree radial growth and climate changeEnvironmental Symbiosis Science DivisionEnvironmental Symbiosis Science DivisionLaboratory of Wild Resource Plant ScienceLaboratory for Forest Environment
