Outline of Final Research Achievements

Studies on winter respiration from forest soils in cool-temperate zone are rather scarce because of low respiration of root-rhizospheres and microbial due to low soil temperature. Therefore, we investigated daily and seasonal dynamics of soil GHGs flux in a cool-temperate deciduous broad-leaved forest located at about 800 m in the Appi Highland, Iwate Prefecture. Throughout our winter surveys, we found that the thick fallen snow lamination became the resistance to GHGs flux from forest soil, and that the vertical distribution of GHGs concentrations in forest soil were affected by the passing of the snowmelt during the early spring.
