Spatial and temporal dynamics of subarctic birch forest carbon exchange
Popular Abstract in English The long-term stability of the global terrestrial carbon sink has been a matter of concern in that a weakening would have serious consequences for atmospheric CO2 concentrations and, hence, for further changes in climate. High northern latitudes are of special importance for the global carbon budget as they store large amounts of organic matter in the soil and are expecHigh northern latitudes are of special importance for the global carbon budget as they store large amounts of organic matter in the soil and are expected to be the most strongly affected by climate change. Here we investigate carbon exchange in the subarctic mountain birch forest growing on the limit where tree growth is possible. The study sites are located close to the Abisko village in norther
