Extreme climate conditions forecasted for Mediterranean areas may change soil C turnover, which is of relevance for soil biogeochemistry modeling. The effect of climate change on soil organic matter (SOM) is investigated in a field experiment mimicking environmental conditions of global change scenarios (soil temperature increase, +2-3 \u00b0C, W; rainfall exclusion, 30%, D; a combination of both, W+D). Pyrolysis-compound-specific isotope analysis (Py-CSIA) is used for C and H isotope characterization of SOM compounds and to forecast trends exerted by the induced climate shift. After 2.5 years, significant \u03b413C and \u03b42H isotopic enrichments were detected. Observed short- and mid-chain n-alkane \u03b413C shifts point to an increased microbial SOM reworking in the W treatment; a 2H enrichment of up to 40\u2030 of lignin methoxyphenols was found when combining W+D treatments under the tree canopy, probably related to H fractionation due to increased soil water evapotranspiration. Our findings indicate that the effect of the tree canopy drives SOM dynamics in dehesas and that, in the short term, foreseen climate change scenarios will exert changes in the SOM dynamics comprising the biogeochemical C and H cycles.", "keywords": ["2.

Net effects result from the combination of direct impacts of grazing on biogeochemical characteristics of microsites with indirect effects on relative cover of vegetated and unvegetated microsites. Within five independent areas, we sampled surface soils in sites subjected to three grazing intensities: (1) ungrazed sites inside grazing exclosures, (2) moderately grazed sites adjacent to them, and (3) intensely grazed sites within the same paddock. Grazing significantly reduced soil C and N pools, although this pattern was clearest in intensely grazed sites. This net effect was due to the combination of a direct reduction of soil N content in bare soil patches, and indirect effects mediated by the increase of the cover of bare soil microsites, with lower C and N content than either grass or shrub microsites. This increase in bare soil cover was accompanied by a reduction in cover of preferred grass species and standing dead material. Finally, stable isotope signatures varied significantly among grazed and ungrazed sites, with \u03b415N and \u03b413C significantly depleted in intensely grazed sites, suggesting reduced mineralization with increased grazing intensity. In the Patagonian steppe, grazing appears to exert a negative effect on soil C and N cycles; sound management practices must incorporate the importance of species shifts within life form, and the critical role of standing dead material in maintaining soil C and N stocks and biogeochemical processes.", "keywords": ["0106 biological sciences", "2.

Drought priming has been proved to improve drought tolerance of plants at later growth stages, however, whether and how drought priming at early growth stage alleviating salinity stress at later growth stage and improving water use efciency (WUE) of plants remains unknown. Therefore, two wheat cultivars were subjected to drought priming at the 4th and 6th leaf stage and subsequent moderate salinity stress at 100 mmol NaCl applied at the later jointing growth stage. The growth, physiological responses, ABA signaling and WUE were investigated to unravel the regulating mechanisms of drought priming on subsequent salinity stress. The results showed that drought priming imposed at the early growth stage improved the leaf and root water potential while attenuated the ABA concentration in the leaves ([ABA]leaf) for the primed plants, which increased the stomatal conductance (gs) and photosynthesis (Pn). Consequently, the biomass under the salinity stress was signifcantly increased due to earlier drought priming. Moreover, drought priming improved the specifc leaf N content due to the facilitated root growth and morphology, and this could beneft high leaf photosynthetic capacity during the salinity stress period, improving the Pn and water uptake for the primed plants. Drought priming signifcantly improved plant level WUE (WUEp) due to considerably enhanced dry biomass compared with non-primed plants under subsequent salinity stress. The signifcantly increased leaf \u03b413C under drought priming further demonstrated that the improved leaf \u03b413C and WUEp was mainly ascribed to the improvement of Pn. Drought primed plants signifcantly improved K+ concentration and maintained the K+/Na+ ratio compared with non-primed plants under subsequent salinity stress, which could mitigate the adverse efects of excess Na+ and minimize salt-induced ionic toxicity by improving salt tolerance for primed plants. Therefore, drought priming at early growth stage could be considered as a promising strategy for salt-prone areas to optimize agricultural sustainability and food security under changing climatic conditions.", "keywords": ["Triticum aestivum L", "0106 biological sciences", "0301 basic medicine", "2.

Backgrounds and aims: Land use is an important factor affecting soil organic carbon (SOC) dynamics and can produce positive C climate feedback, but its effects remain unknown for Tibetan ecosystems. Methods: Recent land use changes have converted the traditional winter Kobresia pastures of nomads in the northeastern Tibetan Plateau to Elymus pastures or even to cropland. Detailed SOC measurements up to 30-cm depth were combined with analysis of \u03b413C, \u03b415N, bulk density, microbial C, and N contents in three land use types. Results: Bulk density was decreased by conversion from Kobresia pasture to cropland but increased by conversion to Elymus pasture. The loss of 1\u00a0% of SOC caused by land use change leads to \u03b413C increase of 0.8 \u2030. Conversion to cropland significantly decreased SOC stocks (10\u00a0%) and microbial biomass C, but the C loss (1.6\u00a0%) was insignificant in Elymus pasture. Land use changes strongly increased soil \u03b415N in the top 5\u00a0cm. Conclusions: Conversion to Elymus pasture did not change the C stocks, but conversion to cropland decreased C stocks by 10\u00a0% within 10\u00a0years.

There is a need to quantify the rates of SOC and N budget changes, and the impact on greenhouse gas emissions from land use change in semi-arid subtropical regions where such data are scarce, so as to assist in developing appropriate management practices. We quantified the turnover rate of SOC from changes in \u03b4(13)C following the conversion of C3 native vegetation to C4 perennial pasture and mixed C3/C4 cereal cropping (wheat/sorghum), as well as \u03b4(15)N changes following the conversion of legume native vegetation to non-legume systems over 23 years. Perennial pasture (Cenchrus ciliaris cv. Biloela) maintained SOC but lost total N by more than 20% in the top 0-0.3m depth of soil, resulting in reduced animal productivity from the grazed pasture. Annual cropping depleted both SOC and total soil N by 34% and 38%, respectively, and resulted in decreasing cereal crop yields. Most of these losses of SOC and total N occurred from the >250 \u03bcm fraction of soil. Moreover, this fraction had almost a magnitude higher turnover rates than the 250-53 \u03bcm and <53 \u03bcm fractions. Loss of SOC during the cropping period contributed two-orders of magnitude more CO2-e to the atmosphere than the pasture system. Even then, the pasture system is not considered as a benchmark of agricultural sustainability because of its decreasing productivity in this semi-arid subtropical environment.

Global soil carbon (C) stocks account for approximately three times that found in the atmosphere. In the Aso mountain region of Southern Japan, seminatural grasslands have been maintained by annual harvests and/or burning for more than 1000\uffc2\uffa0years. Quantification of soil C stocks and C sequestration rates in Aso mountain ecosystem is needed to make well\uffe2\uff80\uff90informed, land\uffe2\uff80\uff90use decisions to maximize C sinks while minimizing C emissions. Soil cores were collected from six sites within 200\uffc2\uffa0km2 (767\uffe2\uff80\uff93937\uffc2\uffa0m asl.) from the surface down to the k\uffe2\uff80\uff90Ah layer established 7300\uffc2\uffa0years ago by a volcanic eruption. The biological sources of the C stored in the Aso mountain ecosystem were investigated by combining C content at a number of sampling depths with age (using 14C dating) and \uffce\uffb413C isotopic fractionation. Quantification of plant phytoliths at several depths was used to make basic reconstructions of past vegetation and was linked with C\uffe2\uff80\uff90sequestration rates. The mean total C stock of all six sites was 232\uffc2\uffa0Mg C\uffc2\uffa0ha\uffe2\uff88\uff921 (28\uffe2\uff80\uff93417\uffc2\uffa0Mg C\uffc2\uffa0ha\uffe2\uff88\uff921), which equates to a soil C sequestration rate of 32\uffc2\uffa0kg C\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0yr\uffe2\uff88\uff921 over 7300\uffc2\uffa0years. Mean soil C sequestration rates over 34, 50 and 100\uffc2\uffa0years were estimated by an equation regressing soil C sequestration rate against soil C accumulation interval, which was modeled to be 618, 483 and 332\uffc2\uffa0kg C ha\uffe2\uff88\uff921\uffc2\uffa0yr\uffe2\uff88\uff921, respectively. Such data allows for a deeper understanding in how much C could be sequestered in Miscanthus grasslands at different time scales. In Aso, tribe Andropogoneae (especially Miscanthus and Schizoachyrium genera) and tribe Paniceae contributed between 64% and 100% of soil C based on \uffce\uffb413C abundance. We conclude that the seminatural, C4\uffe2\uff80\uff90dominated grassland system serves as an important C sink, and worthy of future conservation.

Although Miscanthus sinensis grasslands (Misc\uffe2\uff80\uff90GL) and Cryptomeria japonica forest plantations (Cryp\uffe2\uff80\uff90FP) are proposed bioenergy feedstock systems, their relative capacity to sequester C may be an important factor in determining their potential for sustainable bioenergy production. Therefore, our objective was to quantify changes in soil C sequestration 47\uffc2\uffa0years after a Misc\uffe2\uff80\uff90GL was converted to a Cryp\uffe2\uff80\uff90FP. The study was conducted on adjacent Misc\uffe2\uff80\uff90GL and Cryp\uffe2\uff80\uff90FP located on Mt. Aso, Kumamoto, Japan. After Cryp\uffe2\uff80\uff90FP establishment, only the Misc\uffe2\uff80\uff90GL continued to be managed by annual burning every March. Mass C and N, \uffce\uffb413C, and \uffce\uffb415N at 0\uffe2\uff80\uff9330\uffc2\uffa0cm depth were measured in 5\uffc2\uffa0cm increments. Carbon and N concentrations, C:N ratio, \uffce\uffb413C, and \uffce\uffb415N were measured in litter and/or ash, and rhizomes or roots. Although C input in Misc\uffe2\uff80\uff90GL by M. sinensis was approximately 36% of that in Cryp\uffe2\uff80\uff90FP by C. japonica, mean annual soil C sequestration in Misc\uffe2\uff80\uff90GL (503\uffc2\uffa0kg\uffc2\uffa0C\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0yr\uffe2\uff88\uff921) was higher than that in Cryp\uffe2\uff80\uff90FP (284\uffc2\uffa0kg\uffc2\uffa0C\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0yr\uffe2\uff88\uff921). This was likely the result of larger C input from aboveground litter to soil, C\uffe2\uff80\uff90quality (C:N ratio and lignin concentration in aboveground litter) and possibly more recalcitrant C (charcoal) inputs by annual burning. The difference in soil \uffce\uffb415N between sites indicated that organic C with N had greater cycling between heterotrophic microbes and soil and produces more recalcitrant humus in Misc\uffe2\uff80\uff90GL than in Cryp\uffe2\uff80\uff90FP. Our data indicate that in terms of soil C sequestration, maintenance of Misc\uffe2\uff80\uff90GL may be more advantageous than conversion to Cryp\uffe2\uff80\uff90FP in Aso, Japan.

Recent global trends of increasing woody plant abundance in grass-dominated ecosystems may substantially enhance soil organic carbon (SOC) storage and could represent a strong carbon (C) sink in the terrestrial environment. However, few studies have quantitatively addressed the influence of spatial heterogeneity of vegetation and soil properties on SOC storage at the landscape scale. In addition, most studies assessing SOC response to woody encroachment consider only surface soils, and have not explicitly assessed the extent to which deeper portions of the soil profile may be sequestering C. 2. We quantified the direction, magnitude, and pattern of spatial heterogeneity of SOC in the upper 1.2 m of the profile following woody encroachment via spatially-specific intensive soil sampling across a landscape in a subtropical savanna in the Rio Grande Plains, USA, that has undergone woody proliferation during the past century. 3. Increased SOC accumulation following woody encroachment was observed to considerable depth, albeit at reduced magnitudes in deeper portions of the profile. Overall, woody clusters and groves accumulated 12.87 and 18.67 Mg C ha-1 more SOC compared to grasslands to a depth of 1.2 m. 4. Woody encroachment significantly altered the pattern of spatial heterogeneity of SOC to a depth of 5 cm, with marginal effect at 5-15 cm, and no significant impact on soils below 15 cm. Fine root density explained greater variability of SOC in the upper 15 cm, while a combination of fine root density and soil clay content accounted for more of the variation in SOC in soils below 15 cm across this landscape. 5. Synthesis: Substantial SOC sequestration can occur in deeper portions of the soil profile following woody encroachment. Furthermore, vegetation patterns and soil properties influenced the spatial heterogeneity and uncertainty of SOC in this landscape, highlighting the need for spatially specific sampling that can characterize this variability and enable scaling and modeling. Given the geographic extent of woody encroachment on a global scale, this undocumented deep soil C sequestration suggests this vegetation change may play a more significant role in regional and global C sequestration than previously thought.", "keywords": ["2.

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.
