Data from: Root phenology unresponsive to earlier snowmelt despite advanced aboveground phenology in two subarctic plant communities
Earlier snowmelt at high latitudes advances aboveground plant phenology, thereby affecting water, nutrient and carbon cycles. Despite the key role of fine roots in these ecosystem processes, phenological responses to earlier snowmelt have never been assessed belowground. We experimentally advanced s...
