Abstract
Reconstruction of high-moor formation process by diatom analysis needs to understand the changes in diatom species associated with the hydrarch succession.
Lateral variation of diatom component from high-moor to low-moor might be corresponded to the changes of diatoms associated with the hydrarch succession.
In Bekanbeushi wetlands in the Akkeshi, Eastern Hokkaido, we set a course of traverse from low-moor to high-moor, and collect living diatoms.
As a result of observation, the change in diatom species for each point on the course of traverse was recognized. We discuss about validity of the diatom variation associated with the hydrarch succession.
