Sufficient conditions for climate-driven range expansion of a boreal conifer, Alaska, 2019-2021
Unprecedented modern rates of warming are expected to advance boreal forest into Arctic tundra, thereby reducing albedo, altering C-cycling (carbon-cycling), and changing global climate, yet the patterns and processes of this biome shift remain unclear. We describe the 20th century colonization of a...
