Mass loss, together with nitrogen and carbon loss, from above\uffe2\uff80\uff90ground material and roots of Festuca vivipara were followed for 13 months in a high Arctic polar semi\uffe2\uff80\uff90desert and a low Arctic tree\uffe2\uff80\uff90line dwarf shrub heath. Festuca vivipara for the study was obtained from plants cultivated at two different CO2 concentrations (350 and 500 \uffce\uffbcL L\uffe2\uff80\uff931) in controlled environment chambers in the UK. Each of the four resource types (shoots or roots from plants grown in elevated or ambient CO2 concentrations) was subsequently placed in an experiment simulating aspects of environmental change in each Arctic ecosystem. Air, litter and soil temperatures were increased using open\uffe2\uff80\uff90topped polythene tents at both sites, and a 58% increase in summer precipitation was simulated at the high Arctic site.
Mass loss was greatest at the low Arctic site, and from the shoot material, rather than the roots. Shoots grown under an elevated CO2 concentration decomposed more slowly at the high Arctic site, and more quickly at the low Arctic one, than shoots grown at ambient CO2. After 13 months, greater amounts of C and N remained in above\uffe2\uff80\uff90ground litter from plants grown under elevated, rather than ambient, CO2 at the polar semi\uffe2\uff80\uff90desert site, although lower amounts of C remained in elevated CO2 litter at the low Arctic ecosystem. In the high Arctic, roots grown in the 500 \uffce\uffbcL L\uffe2\uff80\uff931 CO2 concentration decomposed significantly more slowly than below\uffe2\uff80\uff90ground material derived from the ambient CO2 chambers. Elevated CO2 concentrations significantly increased the inital C:N ratio, % soluble carbohydrates and \uffce\uffb1\uffe2\uff80\uff90cellulose content, and significantly decreased the inital N content, of the above\uffe2\uff80\uff90ground material compared to that derived from the ambient treatment. Initially, the C:N ratio and percentage N were similar in both sets of roots derived from the two different CO2 treatments, but soluble carbohydrate and \uffce\uffb1\uffe2\uff80\uff90cellulose concentrations were higher, and percentage lignin lower, in the elevated CO2 treatments.The tent treatments significantly retarded shoot decomposition in both ecosystems, probably because of lower litter bag moisture contents, although the additional precipitation treatment had no effect on mass loss from the above\uffe2\uff80\uff90ground material. The results suggest that neither additional summer precipitation (up to 58%), nor soil temperature increase of 1 \uffc2\uffb0C, which may occur by the end of the next century as an effect of a predicted 4 \uffc2\uffb0C rise in air temperature, had an appreciable effect on root decomposition in the short term in a high Arctic soil. However, at the low Arctic site, greater root decomposition, and a lower pool of root N remaining, were observed where soil temperature was increased by 2 \uffc2\uffb0C in response to a 4 \uffc2\uffb0C rise in air temperature. These results suggest that decomposition below\uffe2\uff80\uff90ground in this ecosystem would increase as an effect of predicted climate change. These data also show that there is a difference in the initial results of decomposition processes between the two Arctic ecosystems in response to simulated environmental change.

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.

It would be expected that both the direct and indirect effects of climate on decomposition act in the same direction along gradients of actual evapotranspiration (AET). However, studies from semiarid ecosystems challenge this idea, suggesting that the climatic conditions that favour decomposition activity, and the consequent ecosystem potential decomposition, do not necessarily lead to litter being easier to decompose. We explored the decomposition patterns of four arid to subhumid native ecosystems with different AET in central\uffe2\uff80\uff90western Argentina and we analysed if ecosystem potential decomposition (climatic direct effect), nutrient availability and leaf litter potential decomposition (climatic indirect effect) all increased with AET. In general, the direct effect of climate (AET) on decomposition (i.e. ecosystem potential decomposition), showed a similar pattern to nutrient availability in soils (higher for xerophytic and mountain woodlands and lower for the other ecosystems), but different from the pattern of leaf litter potential decomposition. However, the range of variation in the ecosystem potential decomposition was much higher than the range of variation in litter potential decomposition, indicating that the direct effect of climate on decomposition was far stronger than the indirect effect through litter quality. Our results provide additional experimental evidence supporting the direct control of climate over decomposition, and therefore nutrient cycling. For the ecosystems considered, those with the highest AET are the ecosystems with the highest potential decomposition. But what is more interesting is that our results suggest that the indirect control of climate over decomposition through vegetation characteristics and decomposability does not follow the same trend as the direct effect of climate. This finding has important implications in the prediction of the effects of climate change on semiarid ecosystems.

Although climate, litter quality and soil organisms clearly modulate carbon (C) and nutrient turnover, land-use change affecting plant species composition and structure can alter the relative importance of such controls. We took advantage of prior land-use changes of intentional planting of exotic forest species along a broad precipitation gradient [250\u20132200 mm mean annual precipitation (MAP)] in Patagonia, South America, where we established five paired sites in natural vegetation and adjacent 35-year-old pine plantations. We explored direct and interactive effects of precipitation and plant community structure on litter decomposition with in situ decomposition, common litters and reciprocal transplants, in addition to an evaluation of microenvironmental changes. Surface litter decomposition in natural vegetation (NV) was similar in all sites along the gradient, independent of litter quality, MAP or soil characteristics, while mass loss demonstrated a significant positive linear relationship with MAP in pine plantations (PP). Decomposition of common litters in PP was markedly reduced with respect to NV, which was > 50% faster at the arid extreme of the gradient. C:N ratios predicted decomposition only in PP, and differences in decomposition were highly correlated with impacts of vegetative cover on incident solar radiation. Synthesis. Concurrent changes in plant cover in NV with increasing MAP resulted in reduced incident solar radiation at the soil surface and decreased the relative importance of photodegradation as a control on surface mass loss. These changes eclipsed direct effects of water availability, litter quality and soil nutrients. In contrast, increased shade and recalcitrant litter with afforestation in PP sites combined such that photodegradation was entirely eliminated as a control and biotic decomposition was much reduced. While afforestation projects are promoted as a strategy to mitigate increased atmospheric carbon dioxide due to human activity, our results highlight that primary controls of litter decomposition were substantially altered with unexpected consequences for the C balance of these ecosystems.", "keywords": ["13.

Increasing evidence suggests that high biomass and litterfall do not necessarily bring about soil organic carbon (SOC) sinks, contrary to the assumption that higher litterfall implies higher SOC when designing carbon models. The underlying mechanism is related to the quality of litter. 2. We conducted 15 years (2000\u20132015) of consecutive field measurements of \u03b413C values in SOC and plants in a pioneer forest (Pinus massoniana forest, PF) and an old-growth forest (monsoon evergreen broadleaved forest, BF), using an isotope mixing model based on mass balance to quantify the effects of vegetation on SOC stock and soil characteristics. 3. The carbon to nitrogen (C/N) ratio of litter in BF was lower than that in PF. The proportion of organic carbon yield input to the soil (Cinput) to the total litter carbon loss during decomposition was 38.7 \u00b1 3.3% and 28.0 \u00b1 2.1% in BF and PF, respectively. New carbon input was higher in BF (148.7 \u00b1 8.8 g C m\u22122 yr\u22121) than PF (99.7 \u00b1 4.5 g C m\u22122 yr\u22121), though there was a non-significant difference in annual litterfall between the two forests. Moreover, the Cinput was concentrated in the topsoil layer in PF but distributed in a more dispersed state across the whole soil profile in BF. Consequently, only the \u03b413C values of SOC decreased in the topsoil layer of PF, whereas these decreased at both soil depths in BF from 2000 to 2015. 4. Compared with PF, BF exhibited higher carbon input and a more favourable soil environment for carbon storage. It was the amount of intermediate product (i.e., Cinput) of litter decomposition, not the amount of litterfall itself, that drove the contrasting differences in SOC status. 5. Synthesis and applications. Litter quality controls SOC accumulation by regulating the fate of decomposing litter, which may explain why old-growth forests can sustainably accumulate carbon in soil. This finding questions the carbon models that predict the dependence of SOC accumulation on biomass and litter yield and suggests that litter quality should be valued in future carbon cycling models.30-Jul-2020", "keywords": ["intermediate product", "soil organic carbon", "13.

We examined the direct effects of long-term warming relative to differences in soil abiotic properties associated with vegetation type on litter decomposition across six subarctic vegetation types.In six vegetation types, rooibos and green tea bags were buried for 70-75\u00a0days at 8\u00a0cm depth inside warmed (by open-top chambers) and control plots that had been in place for 20-25\u00a0years. Standardized initial decomposition rate and stabilization of the labile material fraction of tea (into less decomposable material) were calculated from tea mass losses. Soil moisture and temperature were measured bi-weekly during summer and plant-available nutrients were measured with resin probes.Initial decomposition rate was decreased by the warming treatment. Stabilization was less affected by warming and determined by vegetation type and soil moisture. Soil metal concentrations impeded both initial decomposition rate and stabilization.While a warmer Arctic climate will likely have direct effects on initial litter decomposition rates in tundra, stabilization of organic matter was more affected by vegetation type and soil parameters and less prone to be affected by direct effects of warming.", "keywords": ["Open-top chamber", "2.

To evaluate the effects of vegetation types [alpine shrubland (AS) and alpine meadow (AM)] and litter quality on litter decomposition and related biochemical processes, the decomposition of leaf litter of two dominant shrub species, Sorbus rufopilosa (SR, high quality) and Rhododendron lapponicum (RL, low quality), was studied using the litterbag method in an alpine treeline ecotone on the eastern Tibetan Plateau. After 1 year of decomposition, cellulolytic enzyme activities and gram-negative bacterial biomass were higher in shrubland than in meadow. However, higher fungal biomass, fungal/bacteria ratio and ligninolytic activity were observed in meadow than in shrubland after 2 years of decomposition. During the first year of decomposition, litter decomposition was faster in shrubland than in meadow probably due to the home-field advantage (HFA) effect and the bacteria-dominated decomposition, whereas in later decomposition stages, litter decomposition was faster in meadow than in shrubland, as the HFA effect diminished and fungal-dominated decomposition of recalcitrant components took over. These results indicated that litter quality effects were generally strongest in the first year and diminished in later stages when the effect of vegetation type in incubation sites developed.", "keywords": ["Lignocellulolytic enzyme", "0106 biological sciences", "2.
