One Hundred Years Later and in a Warmer Climate – A Case of Ecotonal Treeline Change in the Swedish Scandes - Juniper Publishers

Ecology & Conservation Science - Juniper Publishers Abstract This paper accounts for a case of substantial transformation of the treeline ecotone (Picea abies (L.) Karst.) in the Swedish Scandes. During the past 100 years, coinciding with summer warming by 1.6 °C, the ecotonal landscape changed from predominance of stunted krummholz individuals to a mosaic of tree groves and intervening alpine tundra.
