Does warming affect growth rate and biomass production of shrubs in the High Arctic?
Few studies have assessed directly the impact of warming on plant growth and biomass production in the High Arctic. Here, we aimed to investigate the impact of 7 years of warming (open greenhouses) on the aboveground relative growth rate (RGR) of Cassiope tetragona and Salix arctica in North-Eastern...

RGR was assessed for apical (leaves, stem, reproductive organs) and lateral meristems (secondary growth of stem and branches) and accompanied by measures of gross ecosystem production (GEP), branching and tissue carbon (C) concentration. Measurements were based on harvest and biometric methods (for RGR and branching) and gas exchange and chemical analysis (for GEP and C concentration).

Summer warming thus has the potential to stimulate biomass production in the High Arctic but major species-specific differences are expected.
