Soil thawing regulates the spring growth onset in tundra and alpine biomes
Abstract: Soil temperature remains isothermal at 0 degrees C and water shifts to a liquid phase during soil thawing. Vegetation may receive this process as a signal and a key to restore physiological activity. We aimed to show the relationship between the timing of soil thawing and the spring growth...
