    • Onset of autumn senescence in High Arctic plants shows similar patterns in natural and experimental snow depth gradients 

      Gehrmann, Friederike; Ziegler, Camille; Cooper, Elisabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-30)
      Predicted changes in snow cover and temperature raise uncertainties about how the beginning and the end of the growing season will shift for Arctic plants. Snowmelt timing and temperature are known to affect the timing of bud burst, but their effects on autumn senescence are less clear. To address this, researchers have examined senescence under natural and experimental environmental gradients. ...

      Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions and moisture availability during winter. It also affects the growing season’s start and end, and plant access to moisture and nutrients. Here, we review the current knowledge of the snow cover’s role for vegetation, plant-animal interactions, permafrost conditions, ...
