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 (plants and plant defense) and Reproductive Biology of Trees as listed below: (Please click in each topic.)
- Forest Physiological Ecology?:Ecophysiological analysis in the responses of forest plants to changing environments, such as elevated 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. An example is shown in the study on Forest Regeneration for spruce and fir;
- Biological interaction analysis in grazing by insect herbivore (plant defense?) and symbiosis of ectomycorrhiza and legume (microbe?).
- Reproduction Biology in Trees?:Reproductive ecology for understanding and improvement of forest regeneration and conservation of forest resources.
