Laboratory of Wild Resource Plant Science Teruo ARASE Associate Professor,Ph.D., Curator Plant ecology, Phytogeography, Plant taxonomy, Utilization & evaluation of wild resource plant, Vegetation recovery, Statistics for field science The purpose of the Laboratory of Wild Resource Plant Science is to study the ecology and taxonomy of wild plants (e.g. edible plants, medicinal plants, or plants available for vegetation recovery), for their use in agronomy and silviculture. We manage the only herbarium in the Faculty of Agriculture where numerous taxonomic specimens are garnered. Ecology, phytogeography, taxonomy of wild plants A B C D A B C Herbarium specimens managed in our laboratory Samples of edible and medicinal fruits (left) Vegetation survey by students (right) Ecology of wild birds related to vegetation recovery, agronomy and silviculture Creation, conservation and management of biotope Utilization and evaluation of wild resource plants Statistics for field science, especially for vegetation, ecological succession, and plant morphology Environmental Symbiosis Science Division 27 Environmental Symbiosis Science Division Laboratory for Forest Environment Koh YASUE Associate Professor, Ph.D. Dendrochronology, Wood anatomy, Climate change, Radial growth, Tree ring Tree radial growth and climate change Tree trunk plays two important role in reduction of atmospheric CO2 concentration, 1) major sink of carbon in terrestrial ecosystems and 2) sustainable carbon neutral materials. We targeted on the relationship between climate change and tree radial growth that develops wood. Dendrochronology Tree 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 dendroclimatological techniques. A B C D A B C Estimation of growth changes of trees under climate change. Research activities of the laboratory members Wood anatomy and formation We 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.
