Decadal soil warming decreased vascular plant above and belowground production in a subarctic grassland by inducing nitrogen limitation
Summary Below and aboveground vegetation dynamics are crucial in understanding how climate warming may affect terrestrial ecosystem carbon cycling. In contrast to aboveground biomass, the response of belowground biomass to long‐term warming has been poorly studied. Here, we characterized the impacts...
