Forest Dynamics Research
Observation on the relationships between organisms and environments
We investigate the responses of biological interactions and communities to environmental change to clarify maintenance and change mechanisms of northern forest and wetland ecosystems. We apply a large variety of research techniques on the field (e.g. field experimental manipulations and long-term monitoring). We consider the whole experimental forest as a huge laboratory. Thus, we energetically conduct field experimental manipulations to get the direct evidence in the relationships between organisms and environments. For example, above- and under-ground parts of mature trees (20m in height) are warmed by electrically heated cables, and long-sequence fences are built to control deer density. Furthermore, we conduct geographical study for comparing forest ecosystem functions and continue for long-term observation on reproductive processes of trees and diversity of insects and fungus. Our research areas include community ecology, forest ecology, conservation ecology, mycology, and entomology.
