Seasonal variation of leaf functional traits in sub‐Arctic plants
Oikos, EarlyView.Leaf functional traits are informative of plant fitness and functions in ecosystems. These functional traits and their variation across geographic extents are much studied but less is known about their temporal variation over a growing season. Here, we provide an analysis of the seasonal variation in six leaf functional traits of 11 sub‐Arctic vascular
