The role of the circumarctic forest–tundra ecotone for Arctic biodiversity
Accepted Version The arctic forest–tundra ecotone (FTE), which links species communities of the boreal forest with those of the arctic tundra, is expected to respond swiftly to climate change with a profound reduction of tundra as the dominating scenario. With its circumarctic expanse and up to seve...
