Climate warming is predicted to rapidly change the local environmental conditions in peatland systems at high latitudes. This study explored soil respiration rates with microbial<br>community compositions along a transect from well-drained upland forest to a Sphagnum<br>moss peatland in boreal Finland. We found that soils from the upland forest and interme-<br>diate habitats incubated at 20°C generally produced more anaerobic CO 2 than the cooler<br>incubation temperature groups (0, 4°C) and that the initial soil carbon content was the<br>strongest geochemical and physical parameter correlated with cumulative CO2 produced<br>over the course of this 140 day incubation. Interestingly, bog samples were the exception<br>to this, and were more productive at cooler temperatures. This implies that the controls on<br>anaerobic CO 2 production in bogs differ from those in the soils of the surrounding habi-<br>tats. This finding, along other parameters, such as soil carbon content, could give greater<br>insights into potential carbon production in high-latitude soils.
