Overview of our research group †
Silviculture and Forest Ecological Stuies
Concept and approach †
We have been studying on the sustainability and conservation of forest resources under changing environment based on Silviculture and Forest Ecology. For approacing this goal, we make researches on Forest Ecophysiology, Forest Dynamics and Ecosystem Ecology on the concept of scaling among leaf, individual and community levels. Main research topics are follows; Forest Physiological Ecology, Population Ecology and Reproductive Ecology of Trees as listed in below: (Please click in each topic.)
Research Topics †
- Forest Physiological Ecology?：Ecophysiological analysis in the responses of forest plants to changing environments, such as elevetaed CO2, nitrogen deposition and soil acidification for sustainability of forest resources.
- Population Dynamics?：Analysis on the species composition and stand structure for understanding forest dynamics in Silviculture; Biological interaction analysis in grazing by insect herbivore and symbiosis of ectomycorrhiza and legume.
- Reproduction Biology in Trees?：Reproductive ecology for understanding of forest regeneration and conservation of forest resources.
