      abstract     = {Based on multi-year measurements of CH(4) exchange in
                      sub-daily resolution we show that clear-cutting of a forest
                      in Southern Germany increased soil temperature and moisture
                      and decreased CH(4) uptake. CH(4) uptake in the first year
                      after clear-cutting (-4.5 ± 0.2 μg C m(-2) h(-1)) was
                      three times lower than during the pre-harvest period (-14.2
                      ± 1.3 μg C m(-2) h(-1)). In contrast, selective cutting
                      did not significantly reduce CH(4) uptake. Annual mean
                      uptake rates were -1.18 kg C ha(-1) yr(-1) (spruce control),
                      -1.16 kg C ha(-1) yr(-1) (selective cut site) and -0.44 kg C
                      ha(-1) yr(-1) (clear-cut site), respectively. Substantial
                      seasonal and inter-annual variations in CH(4) fluxes were
                      observed as a result of significant variability of weather
                      conditions, demonstrating the need for long-term
                      measurements. Our findings imply that a stepwise selective
                      cutting instead of clear-cutting may contribute to
                      mitigating global warming by maintaining a high CH(4) uptake
                      capacity of the soil.},
