Short summary
Bacterial communities in the soils of the Arctic region decompose soil organic matter to CO2 from a large carbon pool. The amount of CO2 released is likely to increase under future climate conditions. Here, we study how temperature sensitive the growth of soil bacterial communties is for 12 sampling sites in the sub to high Arctic. We show that the optimal growth temperature varies between 23 and 34 °C and is influenced by the summer temperature.
