Arctic vegetation is characterized by high spatial variability in plant functional type (PFT) composition and gross primary productivity (P). Despite this variability, the two main drivers of P in sub-Arctic tundra are leaf area index (LT) and total foliar nitrogen (NT). LT and NT have been shown to...

Arctic vegetation is characterized by high spatial variability in plant functional type (PFT) composition and gross primary productivity (P).
