Warmer temperatures promote shrub radial growth but not cover in the central Canadian Arctic
We assessed the response of Salix richardsonii , a deciduous shrub, to climate change by determining the combination of climatic factors that regulated its growth over the past half-century. We tested whether increasing arctic temperatures promote shrub growth and increased cover. We analyzed fifty-...
