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...
