Arctic alpine vegetation change over 20 years
Abstract Recent arctic warming experiments have recorded significant vegetation responses, typically an increase in shrub cover and a loss of species richness. We report similar changes in vegetation along an arctic mountainside in northern Sweden over 20 years. During this time mean annual temperat...

Abstract Recent arctic warming experiments have recorded significant vegetation responses, typically an increase in shrub cover and a loss of species richness.
