Spatial and temporal variability in the responses of Arctic terrestrial ecosystems to environmental change

This paper compares the responses of two contrasting Arctic ecosystems to climate change simulations: a polar semi‐desert (in Svalbard) and a dwarf shrub heath (at Abisko, northern Sweden). These ecosystems are located close to the northern‐and southernmost extremes of the Arctic region, respectively. Inmacts of simulated climatic changes were determined through factorial perturbation experiments, where growing season temperature, nutrient …
