| Research Abstract |
This project was conducted in northern Hokkaido, northern Kanto, central Kinki and southern Kyusyu to understand the pattern and factors of the alteration in nitrogen dynamics of forest soil along with the climatic gradient in Japanese archipelago. While the warming increased soil microbial metabolisms of nitrogen, each specific characteristic of soil nitrogen dynamics in each site was relatively maintained even under the climate change. It was suggested that the much atmospheric nitrogen deposition and the previous human utilization of forest resources strongly influenced the differences among the sites.
