Arctic rooting depth distribution influences modelled carbon emissions but cannot be inferred from aboveground vegetation type
Summary The distribution of roots throughout the soil drives depth‐dependent plant–soil interactions and ecosystem processes, particularly in arctic tundra where plant biomass, is predominantly belowground. Vegetation is usually classified from aboveground, but it is unclear whether such classificat...
