Data from: Winter warming effects on tundra shrub performance are species-specific and dependent on spring conditions
1. Climate change driven increases in winter temperatures positively affect conditions for shrub growth in arctic tundra by decreasing plant frost damage and stimulation of nutrient availability. However, the extent to which shrubs may benefit from these conditions may be strongly dependent on the f...

By insulating sparsely vegetated non-sorted circles and parts of the surrounding heath with additional snow or gardening fleeces we created two climate change scenarios: Snow addition increased soil temperatures in autumn and winter and delayed snowmelt timing without increasing spring temperatures, whereas fleeces increased soil temperature similarly in autumn and winter, but created warmer spring conditions without altering snowmelt timing. 3.
