    Fine root dynamics and partitioning of root respiration into growth and maintenance components in cool temperate deciduous and evergreen forests

    We aim to show the seasonality of fine root dynamics and examine the relationship between root respiration (Rr) and fine root dynamics. In addition, we try partitioning Rr into growth (Rg) and maintenance (Rm) co...

    Controlling the Depth of Soil Frost in Farm Fields in Japan

    Winter climate change has resulted in earlier onset of deep snow cover and reduced soil-frost depth in eastern Hokkaido, Japan, since the late 1980s. In the Tokachi region, a major potato-producing area of Jap...

    Soil Frost Control: Its Application to Volunteer Potato Management in a Cold Region

    The earlier onset of persistent snowcover since the late 1980s has narrowed the time window for soil-surface cooling without insulating snowcover, drastically reducing the soil frost depth in eastern Hokkaido,...

    Effects of snow-load and shading by vascular plants on the vertical growth of hummocks formed by Sphagnum papillosum in a mire of northern Japan

    The growth of hummock Sphagnum species in bogs depends on hydrological and climatic conditions, with different hummock morphologies being found across geographical regions. We investigated how plant shade and win...

    Soil frost control: agricultural adaptation to climate variability in a cold region of Japan

    In the northernmost region of Japan (Hokkaido Island), earlier onsets of thick snowcover in recent years (post 1980) have reduced the penetration depth of soil frost, resulting in over-winter survival of unhar...
