The Lack of Snow in a Boreal Forest May Reduce Summer Feeding Activity of Soil Invertebrates
Russian Journal of Ecology(2022)
摘要
In order to assess the effect of snow cover on the feeding activity of soil detritivores in the middle taiga, a short-term field experiment has been carried out. On the experimental plots in the blueberry-green-moss spruce forest, snow was removed in winter and the feeding activity of soil animals was assessed using the bait-lamina test in the subsequent growing season. Untreated sites served as controls. The absence of snow cover led to a significant freezing of the soil and reduced the feeding activity in the forest litter by 11.4%, while the activity in the underlying mineral soil remained almost unchanged.
