Holocene history of the forest–alpine tundra ecotone in the Scandes Mountains (central Sweden)
summary The Holocene history of the forest‐alpine tundra ecotone in Central Sweden (Scandes Mountains) is inferred from radiocarbon analyses of subfossil wood remains. Pinus sylvestris was the dominant subalpine tree species during the early Holocene, when it ascended almost 200 m higher than curren...
