Climate and land-use changes have altered both litter quality and quantity, with cascading impacts on soil respiration (SR). Soil extracellular enzymes (EEs) like cellulase and ligninase are crucial for deconstructing plant litter because they convert polymers into monomers. However, whether and how changes in litter inputs influence soil cellulase and ligninase activities as well as the implications for SR remain poorly understood. We conducted a global meta-analysis of 827 observations on the responses of SR and soil cellulase and ligninase activities to litter addition and litter removal. Litter addition significantly increased cellulase activity by 25 %, whereas litter removal decreased it by 26 %. Neither litter addition nor litter removal affected ligninase activity. Changes in cellulase activity correlated positively with SR under both litter addition and litter removal, but no such relationship was found for ligninase activity. These results indicate that changes in litter inputs affect SR primarily by affecting the microbial decomposition of readily decomposable rather than more structurally complex carbon pools. In addition, the effects of changes in litter inputs on cellulase activity decreased with treatment duration, suggesting that the long-term effects of changes in litter inputs on SR might be smaller than previously thought. Our results underscore the dominant role of cellulase in mediating the responses of SR to altered litter inputs. Integrating cellulase responses to altered litter inputs into Earth system models could improve the representation of microbial processes and refine the predictions of soil carbon dynamics.

We therefore quantified the net ecosystem production (NEP) of a poplar (Populus) short rotation coppice (SRC) culture in Flanders during its second growing season.Eddy covariance (EC) techniques were applied to obtain the annual net ecosystem exchange (NEE) of the plantation. Further, by applying a component-flux-based approach NEP was calculated as the difference between the modelled gross photosynthesis and the respiratory fluxes from foliage, stem and soil obtained via upscaling from chamber measurements. A combination of biomass sampling, inventories and upscaling techniques was used to determine NEP via a pool-change-based approach.Across the three approaches, the net carbon balance ranged from 96 to 199\u00a0g\u00a0m\u22122\u00a0y\u22121 indicating a significant net carbon uptake by the SRC culture. During the establishment year the SRC culture was a net source of carbon to the atmosphere, but already during the second growing season there was a significant net uptake. Both the component-flux-based and pool-change-based approaches resulted in higher values (47\u2013108%) than the EC-estimation of NEE, though the results were comparable considering the considerable and variable uncertainty levels involved in the different approaches. The efficient biomass production \u2013 with the highest part of the total carbon uptake allocated to the aboveground wood \u2013 led the poplars to counterbalance the soil carbon losses resulting from land use change in a short period of time.", "keywords": ["2.

However, it has yet to be determined whether net soil C sequestration occurs in N\uffe2\uff80\uff90rich grasslands exposed to long\uffe2\uff80\uff90term elevated CO2. This study examined whether N\uffe2\uff80\uff90fertilized grasslands exposed to elevated CO2 sequestered additional C. For 10 years, Lolium perenne, Trifolium repens, and the mixture of L. perenne/T. repens grasslands were exposed to ambient and elevated CO2 concentrations (35 and 60\uffe2\uff80\uff83Pa pCO2). The applied CO2 was depleted in \uffce\uffb413C and the grasslands received low (140\uffe2\uff80\uff83kg\uffe2\uff80\uff83ha\uffe2\uff88\uff921) and high (560\uffe2\uff80\uff83kg\uffe2\uff80\uff83ha\uffe2\uff88\uff921) rates of 15N\uffe2\uff80\uff90labeled fertilizer. Annually collected soil samples from the top 10\uffe2\uff80\uff83cm of the grassland soils allowed us to follow the sequestration of new C in the surface soil layer. For the first time, we were able to collect dual\uffe2\uff80\uff90labeled soil samples to a depth of 75\uffe2\uff80\uff83cm after 10 years of elevated CO2 and determine the total amount of new soil C and N sequestered in the whole soil profile. Elevated CO2, N\uffe2\uff80\uff90fertilization rate, and species had no significant effect on total soil C. On average 9.4\uffe2\uff80\uff83Mg new C\uffe2\uff80\uff83ha\uffe2\uff88\uff921 was sequestered, which corresponds to 26.5% of the total C. The mean residence time of the C present in the 0\uffe2\uff80\uff9310\uffe2\uff80\uff83cm soil depth was calculated at 4.6\uffc2\uffb11.5 and 3.1\uffc2\uffb11.1 years for L. perenne and T. repens soil, respectively. After 10 years, total soil N and C in the 0\uffe2\uff80\uff9375\uffe2\uff80\uff83cm soil depth was unaffected by CO2 concentration, N\uffe2\uff80\uff90fertilization rate and plant species. The total amount of 15N\uffe2\uff80\uff90fertilizer sequestered in the 0\uffe2\uff80\uff9375\uffe2\uff80\uff83cm soil depth was also unaffected by CO2 concentration, but significantly more 15N was sequestered in the L. perenne compared with the T. repens swards: 620 vs. 452\uffe2\uff80\uff83kg\uffe2\uff80\uff83ha\uffe2\uff88\uff921 at the high rate and 234 vs. 133\uffe2\uff80\uff83kg\uffe2\uff80\uff83ha\uffe2\uff88\uff921 at the low rate of N fertilization. Intermediate values of 15N recovery were found in the mixture. The fertilizer derived N amounted to 2.8% of total N for the low rate and increased to 8.6% for the high rate of N application. On average, 13.9% of the applied 15N\uffe2\uff80\uff90fertilizer was recovered in the 0\uffe2\uff80\uff9375\uffe2\uff80\uff83cm soil depth in soil organic matter in the L. perenne sward, whereas 8.8% was recovered under the T. repens swards, indicating that the N2\uffe2\uff80\uff90fixing T. repens system was less effective in sequestering applied N than the non\uffe2\uff80\uff90N2\uffe2\uff80\uff90fixing L. perenne system. Prolonged elevated CO2 did not lead to an increase in whole soil profile C and N in these fertilized pastures. The potential use of fertilized and regular cut pastures as a net soil C sink under long\uffe2\uff80\uff90term elevated CO2 appears to be limited and will likely not significantly contribute to the mitigation of anthropogenic C emissions.

The arctic biome is currently increasing in deciduous shrub cover and this increase is expected to continue with climate warming. However, little is known how current deciduous shrub communities will respond to future climate induced warming and nutrient increase. We examined the plant and ecosystem response to a long\uffe2\uff80\uff90term (18 years) nutrient addition and warming experiment in an Alaskan arctic tall deciduous shrub tundra ecosystem to understand controls over plant productivity and carbon (C) and nitrogen (N) storage in shrub tundra ecosystems. In addition, we used a meta\uffe2\uff80\uff90analysis approach to compare the treatment effect size for aboveground biomass among seven long\uffe2\uff80\uff90term studies conducted across multiple plant community types within the Arctic. We found that biomass, productivity, and aboveground N pools increased with nutrient additions and warming, while species diversity decreased. Both nutrient additions and warming caused the dominant functional group, deciduous shrubs, to increase biomass and proportional C and N allocation to aboveground stems but decreased allocation to belowground stems. For all response variables except soil C and N pools, effects of nutrients plus warming were largest. Soil C and N pools were highly variable and we could not detect any response to the treatments. The biomass response to warming and fertilization in tall deciduous shrub tundra was greater than moist acidic and moist non\uffe2\uff80\uff90acidic tundra and more similar to the biomass response of wet sedge tundra. Our data suggest that in a warmer and more nutrient\uffe2\uff80\uff90rich Arctic, tall deciduous shrub tundra will have greater total deciduous shrub biomass and a higher proportion of woody tissue that has a longer residence time, with a lower proportion of C and N allocated to belowground stems.
