“…Soil water content is usually considered to be an important regulator of CH 4 fluxes in soils (Castro et al, 2000;Guckland et al, 2009). Weak but significant linear regressions between CH 4 fluxes and soil moisture, expressed as WFPS, were observed in the present study, which was in accordance with previous studies (Butterbach-Bahl and Papen, 2002;Borken et al, 2003).…”

“…This could be a relevant mechanism for the Höglwald, as an earlier study at these sites demonstrated that the soil C and N turnover rates were significantly higher at the clear-cut site as compared to the control (Rosenkranz et al, 2010). Much more evident than the potential role of N turnover in regulating soil CH 4 fluxes is the fact that the microbially mediated CH 4 consumption is substantially limited by the diffusivity of CH 4 and O 2 availability in the soil (Le Mer and Roger, 2001), which in turn are regulated by the soil water content Guckland et al, 2009). In our study, the long time periods of significantly higher soil moisture values after clear-cutting may be the major factor leading to the drastic reduction of CH 4 fluxes at the clear-cutting site as compared to control site.…”

a b s t r a c tBased 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 (À4.) was three times lower than during the pre-harvest period (À14.2 AE 1.3 mg C m À2 h À1 ). In contrast, selective cutting did not significantly reduce CH 4 uptake. Annual mean uptake rates were À1.18 kg C ha À1 yr À1 (spruce control), À1.16 kg C ha À1 yr À1(selective cut site) and À0.44 kg C ha À1 yr À1 (clear-cut site), respectively. Substantial seasonal and interannual 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.

“…Soil moisture and water table depth vary spatially due to, for example, topography, which results in spatial variations of CH 4 exchange (Lessard et al, 1994;Yu K. W. et al, 2008). There is also a temporal variability in CH 4 exchange, mainly due to changes in temperatures and precipitation (Castro et al, 1994;Guckland et al, 2009). CH 4 production is strongly favoured by increasing temperatures, while CH 4 oxidation is not as sensitive to temperature changes (Dunfield et al, 1993;Yvon-Durocher et al, 2014).…”

“…To date, most in situ measurements of CH 4 have been made with chambers (e.g., Crill et al, 1994;Bradford et al, 2000;Guckland et al, 2009). They are suitable for detailed studies of processes controlling CH 4 exchange, but they might not be spatially representative for a larger area (Denmead, 2008), and semi-continuous measurements are only possible with automated chambers.…”

A B S T R A C T Forests are generally considered to be net sinks of atmospheric methane (CH 4 ) because of oxidation by methanotrophic bacteria in well-aerated forests soils. However, emissions from wet forest soils, and sometimes canopy fluxes, are often neglected when quantifying the CH 4 budget of a forest. We used a modified Bowen ratio method and combined eddy covariance and gradient methods to estimate net CH 4 exchange at a boreal forest site in central Sweden. Results indicate that the site is a net source of CH 4 . This is in contrast to soil, branch and leaf chamber measurements of uptake of CH 4 . Wetter soils within the footprint of the canopy are thought to be responsible for the discrepancy. We found no evidence for canopy emissions per se. However, the diel pattern of the CH 4 exchange with minimum emissions at daytime correlated well with gross primary production, which supports an uptake in the canopy. More distant source areas could also contribute to the diel pattern; their contribution might be greater at night during stable boundary layer conditions.

The importance of landscape diversity for carbon fluxes at the landscape level: small‐scale heterogeneity matters

et al. 2016

Landscapes can be viewed as spatially heterogeneous areas encompassing terrestrial and aquatic domains. To date, most landscape carbon (C) fluxes have been estimated by accounting for terrestrial ecosystems, while aquatic ecosystems have been largely neglected. However, a robust assessment of C fluxes on the landscape scale requires the estimation of fluxes within and between both landscape components. Here, we compiled data from the literature on C fluxes across the air-water interface from various landscape components. We simulated C emissions and uptake for five different scenarios which represent a gradient of increasing spatial heterogeneity within a temperate young moraine landscape: (I) a homogeneous landscape with only cropland and large lakes; (II) separation of the terrestrial domain into cropland and forest; (III) further separation into cropland, forest, and grassland; (IV) additional division of the aquatic area into large lakes and peatlands; and (V) further separation of the aquatic area into large lakes, peatlands, running waters, and small water bodies These simulations suggest that C fluxes at the landscape scale might depend on spatial heterogeneity and landscape diversity, among other factors. When we consider spatial heterogeneity and diversity alone, small inland waters appear to play a pivotal and previously underestimated role in landscape greenhouse gas emissions that may be regarded as C hot spots. Approaches focusing on the landscape scale will also enable improved projections of ecosystems' responses to perturbations, e.g., due to global change and anthropogenic activities, and
