I am interested in the role of vegetation as ecosystem structure and influence of vegetation changes on ecosystem functions. Environmental change impacts vegetation, the change of which alters environment, and the role of ecosystem in the biosphere can be shifted. My main esearch focus is in northern mires – peat accumulating wetlands.
