Typhlocharisis the most diverse eyeless endogean ground beetle genus known to date, with 62 species all endemic to the West Mediterranean region. The lineage is characterized by a conservative and singular body plan within Carabidae that contrasts with a high morphological diversity in many traits. We provide an exhaustive phylogeny of the lineage through the study of 92 morphological characters from all 62 described species and 45 potential new species from 70 additional populations, and the combination of morphological and available molecular data, in the first total evidence phylogenetic approach for a highly diverse endogean lineage. We tracked the evolution of morphological traits over the obtained phylogenies. Results suggest eight morphologically distinct clades, which do not correspond to the species groups proposed formerly. Ancestral state reconstructions and phylogenetic signal analyses of morphological traits revealed that some of the previously key characters to the classification ofTyphlocharis, such as the umbilicate series or the apical denticles of elytra, are highly homoplasic, whereas other characters show stronger phylogenetic signal, including structures in the antennae, gula, pronotum and last abdominal ventrite. This evidence supports the split ofTyphlocharisinto three genera:Lusotyphlusgen. nov.;TyphlocharisDieck, 1869 andMicrocharidiusCoiffait, 1969 (revalidated), forming the subtribe Typhlocharina Jeanne, 1973. 0.06), in which the OPF was significantly greater than the YPF (P < 0.001). The cracks area density, however, was lower in the OPF (3.66%) than in the YPF (5.13%). This discrepancy can be explained by more swelling clay content and higher soil organic matter in the OPF but greater AFD intensity in the YPF. As a result, the YPF showed higher water percolation as compared with the OPF. Our work demonstrates that the temporal changes in soil structure in paddy soils depend not only on intrinsic soil properties but also on external hydraulic stress.", "keywords": ["2.

Short-term soil incubations (29\u00a0days) were used to investigate the effects of agriculturally relevant biochar applications from two contrasting feedstocks and temperatures on CO 2 and N 2 O emissions from a fertile agricultural soil amended with different types of fertilizer (organic and synthetic). In addition, the effects of biochar on the denitrification process were examined using an acetylene based method to ascertain N 2 O and N 2 emissions during denitrification. Complementary incubation experiments without soil (biochar and biochar with compost) examined the impact on natural or amended organic matter (compost) and biochar stability and surface chemistry were also investigated. Batch incubations (25\u00a0\u00b0C) of biochar (softwood pyrolyzed at 410\u00a0\u00b0C [WF 410 ] and 510\u00a0\u00b0C [WF 510 ] and walnut shell pyrolyzed at 900\u00a0\u00b0C [WA 900 ]) amended soils were performed to determine emissions of CO 2 and N 2 O due to complete (absence of acetylene [C 2 H 2 ]) and incomplete denitrification (presence of C 2 H 2 ). Similarly, GHG emissions from the complementary incubations were also measured. Concurrent biochar surface compositional changes were investigated with attenuated total reflectance (ATR) Fourier transform infrared (FTIR) spectroscopy. Biochar effects on CO 2 emissions were not significantly different from controls. WA 900 biochar (high pH) affects N cycling resulting in significantly higher emissions of N 2 O under conditions of complete denitrification and of N 2 under conditions examining incomplete denitrification. WF 410 (highest H/C ratio and lowest surface area) treatments with compost resulted in higher GHGs emissions which is attributed to a priming effect of the compost organic matter (COM). In addition, WF 410 was most susceptible to degradation, evident from infrared spectroscopic analysis of the biochars. Although these results suggest that not all biochars provide substantial benefits as a soil amendment, the data do demonstrate potential for development of biochars with beneficial impacts on GHG emission mitigation and enhancement of soil C stocks.", "keywords": ["2.

Here we investigated soil extractable organic carbon (EOC) and nitrogen (EON), microbial biomass and microbial metabolic activities at two depths of 0\u201310 and 10\u201320\u00a0cm in response to single and combined effects of warming and increased precipitation in a semiarid grassland of northern China since April 2005. Soil EOC and EON pools were measured using KCl and hot water extractions, and microbial metabolic activities were measured using MicroResp. Results showed that warming had no effects on EOC, EON and microbial biomass C (MBC) and N (MBN) in the two extracts as well as the ratio of MBC to MBN at the two depths, but increased precipitation significantly increased MBC, MBN, EON and microbial quotient at the 0\u201310\u00a0cm depth. Warming significantly decreased microbial metabolic activities at both soil depths, but significantly increased microbial metabolic diversity (H) and evenness (E) at the 10\u201320\u00a0cm depth. Increased precipitation significantly decreased microbial metabolic activities, but significantly increased H and E at the two depths. Warming and increased precipitation significantly interacted to affect microbial metabolic activities at the two depths as well as H and E at the 10\u201320\u00a0cm depth. Redundancy analysis determined that microbial quotient, i.e., the ratio of MBC to total C, pH and NH 4 + \u2013N greatly accounted for the variances in the soil microbial metabolic profiles, but the ratio of EOC to EON, moisture and microbial quotient largely accounted for the variances in the soil microbial metabolic profiles specifically at the 10\u201320\u00a0cm depth, implying that microbial physiology such as microbial quotient rather than the amounts of labile organic C and N pools exerted more influence on driving the patterns of microbial metabolic profiles.

The data on changes in SOC pools are needed to enhance scientific knowledge regarding the effects of land use and no-till (NT) systems on soil fertility, agronomic productivity, and soil C sink capacity. Thus, the objective of this study was to quantify changes in SOC fractions due to conversion of NV to agricultural land, and to assess the rate of recovery of SOC fractions and the resilience index of NT cropping systems under sub-tropical (Ponta Grossa/PR \u2014 PG) and tropical (Lucas do Rio Verde/MT \u2014 LRV) regions of Brazil. The conversion from CT to NT was 29 and 8\u00a0years at the PG and LRV sites, respectively. Five different fractions of SOC pools were extracted by chemical methods (i.e., C in the polysaccharides \u2014 CTPS, hot-water extractable C \u2014 HWEOC, chemically-stabilized organic C \u2014 CSOC), and physical fractionation (i.e., particulate organic C \u2014 POC, and mineral-associated organic C \u2014 MAOC). Land use change primarily altered the labile (HWEOC, TPS, and POC) and also some of the stable (MAOC) pools at both sites. The CSOC pool was almost constant throughout the soil profile and represented, across land uses, 7.2\u00a0g\u00a0C\u00a0kg \u2212\u00a01 at the PG and 3.1\u00a0g\u00a0C\u00a0kg \u2212\u00a01 at the LRV sites. At the PG site, the HWEOC and CTPS concentrations in the 0\u20135\u00a0cm depth decreased by 56% (1.21\u00a0g\u00a0kg \u2212\u00a01 ) and 45% (7.21\u00a0g\u00a0kg \u2212\u00a01 ) in CT soil, respectively. At the LRV site, concentrations of HWEOC and CTPS in the 0\u20135\u00a0cm depth decreased by 50% (0.4\u00a0g\u00a0kg \u2212\u00a01 ) and 42% (4.8\u00a0g\u00a0kg \u2212\u00a01 ), respectively. In contrast, concentrations of HWEOC and CTPS fractions in soil under NT in the 0\u201320\u00a0cm depth were closer than those under NV, and exhibited a distinct gradient from surface to sub-soil layers. The adoption of CT reduced POC by 46% (4.7\u00a0Mg\u00a0ha \u2212\u00a01 ), and MAOC by 21% (15.1\u00a0Mg\u00a0C\u00a0ha \u2212\u00a01 ) in the 0\u201320\u00a0cm depth at the PG site. Using CT for 23\u00a0years at the LRV site, decreased SOC fractions in the 0\u201320\u00a0cm depth at the rate of 0.25 and 0.34\u00a0Mg\u00a0C\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 for POC and MAOC, respectively. In contrast, adoption of intensive NT systems in tropical agro-ecoregions increased POC at the rate of 0.23 to 0.36\u00a0Mg\u00a0C\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 , and MAOC by 0.52 and 0.70\u00a0Mg\u00a0C\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 . An important effect to be emphasized is the possibility of recovering, at least partially, the SOC fractions by adopting high biomass-C inputs under NT management, and despite the fact that the experimental duration at the LRV site was only eight years. With a high and diversified input of biomass-C in intensive NT systems, higher resilience index was observed for CTPS, HWEOC, and MAOC. The variation in SOC among CT and NT systems was mainly attributed to the MAOC fraction, indicating that a significant proportion of that fraction is relatively labile, and that spatial inaccessibility of SOC plays a significant role in the restoration of SOC.", "keywords": ["P33 - Chimie et physique du sol", "F07 - Fa\u00e7ons culturales", "P36 - \u00c9rosion", " conservation et r\u00e9cup\u00e9ration des sols", "2.

Ash properties depend on vegetation type, amount of fuel and fire intensity. The ash layer controls the post-fire soil hydrologic response, but little is known about the effect of ash thickness and ash type on infiltration, which is relevant for post-fire runoff and soil losses and for ecosystems rehabilitation and restoration. This paper analyses the role of i) ash type (black or white), ii) thickness (5, 15 and 30\u00a0mm-thick) and iii) temporal variation (0, 15 and 40\u00a0days) under three simulated rain events (55\u00a0mm for 1\u00a0h) on soil surface hydrology. The rainfall was simulated on 0.25\u00a0m2 plots, and time to ponding, runoff and runoff discharge were measured. The infiltration rates, the initial infiltration rate (f0), the steady-state infiltration rate (fc), and the infiltration decay factor (k), were calculated and the Horton infiltration equation applied. The results show that soils covered with white ash doubled the runoff rates of soils covered with black ash. In general, runoff decreases as the ash thickness increases and the runoff decreases with the number of rainfall events after the fire in plots covered with white ash. Ponding time and k are positively correlated by the ash thickness and f0 and fc are correlated by the rainfall events (in three runs). Ash type and ash depth are key factors on the soil hydrology after a wildfire.", "keywords": ["13.

The objective of this study is to assess the long-term cumulative effects of change in land-use type on some soil properties in the continental lowland ecosystems of Western Serbia. Three adjacent land-use types (deciduous forest, natural grassland and arable soils that have been converted from forests for more than 100\u00a0years) were chosen for the study. Disturbed and undisturbed soil samples were collected from nine sites at each of the three different land-use types from the depths of 0\u201310, 10\u201320 and 20\u201330\u00a0cm in noncarbonated Fluvisol. Conversion of forest to grassland and arable soil has led to significant decrease in total porosity (TP), infiltration rate (IR) and soil organic matter (SOM). The bulk density (BD) was lower in forest compared to the adjacent grassland and arable (ex-forest) soils. In addition, microaggregate stability, determined by the clay dispersion ratio (CDR) and aggregated silt and clay (ASC) indices, was significantly higher in forest than in grassland and arable soil. In conclusion, the results of this study indicate that removal of permanent vegetation in the conversion process from forest and grassland areas to cultivated land may lead to loss of soil productivity and serious soil degradation.

Especially the impact on physical properties is not well investigated so far. We study the impacts of biochar (BC) and hydrochar (HTC) on water retention characteristics (WRC) as well as on the wettability of sandy soils, using lab and field studies. Sandy soils with different amounts of organic matter were mixed with BC z (feedstock maize) and HTC (feedstock maize silage). Added amounts were 1, 2.5, and 5\u00a0wt.%, respectively. The mixtures were packed in 100\u00a0cm 3 soil columns. In a field campaign identical amounts of BC f (feedstock beechwood) were added to the soil. Six months after incorporation undisturbed soil samples were taken. For these field samples available water capacity (AWC) was determined. For the packed soil columns the WRC was measured in the pressure head range from saturation to wilting point (\u2212\u00a015,848\u00a0cm). The extent of water repellency was determined for all samples using the water drop penetration time test. Addition of biochar leads to a decrease in bulk density, an increase in total pore volume as well as an increase in water content at the permanent wilting point. An increase in AWC could be observed for all sandy substrates used, except for the highly humic sand. Notable differences in the effects on the AWC could be measured among the three chars used. Particle size distribution of the chars as well as their consistency had different impacts on the pore size distribution of the soil matrix. No direct impact of the chars on the wettability of the soils could be observed. Local spots with hydrophobic character were detected among the samples with hydrochar, attributed to fungal colonisation.", "keywords": ["0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "15.

We determined the LLWR for long-term tillage and cropping system experiments on an Argiustoll in the central U.S. Great Plains. The tillage (46\u00a0years) experiment consisted of wheat (Triticum aestivum L.)\u2013sorghum [Sorghum bicolor (L.) Moench]\u2013fallow (WSF) rotation under conventional tillage (CT), reduced tillage (RT) and no-tillage (NT), while the cropping system (35\u00a0years) experiment consisted of wheat\u2013fallow (WF), WSF and continuous wheat (WW) rotations managed under RT and NT. Soil water retention curves, penetration resistance curves and bulk density were determined for the 0 to 5\u00a0cm and 5 to 10\u00a0cm depths to compute the LLWR. Mean LLWR did not differ among tillage systems for the 0 to 5\u00a0cm depth, but it was higher in RT and CT than in NT for the 5 to 10\u00a0cm depth. Mean LLWR was higher for WW than for WSF and WF in RT at both depths, but it did not differ in NT. Across cropping systems, LLWR in RT was greater than in NT by 1.2 times for the 0 to 5\u00a0cm and by 4.7 times for the 5 to 10\u00a0cm depth. Analysis of the upper and lower limits of the LLWR suggested that aeration and penetration resistance were plant-growth limiting factors in both experiments. Both tillage and cropping systems were associated with a narrow LLWR, which may reflect the limited water availability in this semiarid region. Overall, the LLWR was a useful indicator of the soil physical condition for plant growth under these long-term tillage and cropping systems and indicated that RT may produce the best soil seedbed in the central Great Plains.", "keywords": ["2.

The objective of this study was to investigate to what extent the addition of corn stover (CS) and biochars produced from the pyrolysis of corn stover feedstock (CS) at 350 and 550 degrees C temperatures (CS-350, CS-550) affected aggregate stability, volumetric water content (theta(V)), bulk density, saturated hydraulic conductivity (Ks) and soil water repellency of specific soils. Organic amendments (CS, CS-350, CS-550) were incorporated into a Typic Fragiaqualf (TK) and a Typic Hapludand (EG) soils at the rate of 7.18 t C ha(-1), which corresponded to 17.3, 11.3 and 10.0 t biochar ha(-1) for the CS, CS-350 and CS-550 treatments, respectively. After 295 d of incubation (1295), soils were sampled as (i) undisturbed samples for bulk density and Ks; and (ii) mildly disturbed samples for theta(V) (at -15, -1, -0.3, -0.1, -0.08, -0.06, -0.04, and -0.02 bar), aggregate stability and soil water repellency. The theta(V) at time 0 (TO) was also determined at -15, -1 and -0.3 matric potentials for the different treatments. Biochar application significantly increased (P l 0.05) aggregate stability of both soils, the effect of CS-550 biochar being more prominent in the TK soil than that in the EG soil, and the reverse pattern being observed for the CS-350 biochar. Biochar application increased the By at each matric potential although the effect was not always significant (P l 0.05) and was generally more evident in the TK soil than that in the EG soil, at both T0 and T295. Biochar addition significantly (P l 0.05) increased the macroporosity (e.g., increase in theta(V) at -0.08 to 0 bar) in the TK soil and also the mesoporosity in the EG soil (e.g., increase in theta(V) from -1 to -0.1 bar). Both biochars significantly increased (P l 0.05) the Ks of the TIC soil, but only CS-350 biochar significantly increased (P l 0.05) the Ks in the EG soil. Biochar was not found to increase the water repellency of these soils. Overall results suggest that these biochars may facilitate drainage in the poorly drained TIC soil. However, the present results are biochar-, dose- and soil-specific. More research is needed to determine changes produced in other biochar, dose and soil combination, especially under field conditions. (C) 2013 Elsevier B.V. All rights reserved.", "keywords": ["2.

Despite the great interest in the effect of no-tillage (NT) management practice on carbon sequestration, the long-term effect of NT practice on soil organic carbon and its fractions in northern China remain unclear. We evaluated the long-term effects (after 17\u00a0years) of NT and conventional tillage (CT) practices on soil organic carbon and its fractions at different depths ranging from 0 to 60\u00a0cm using a cinnamon soil in Shanxi, China. A randomised block design with three replications was used to evaluate both the tillage and its effects on the yield performance of winter wheat ( Triticum aestivum L.). After 17\u00a0years, the soil organic carbon (SOC) concentration in the NT soil was greater than that of the CT soil, but only in the layer that was located between 0 and 10\u00a0cm. There was a significant accumulation of SOC (0\u201360\u00a0cm) in the NT soil (50.2\u00a0Mg\u00a0C\u00a0ha \u2212\u00a01 ) compared to that observed in the CT soil (46.3\u00a0Mg\u00a0C\u00a0ha \u2212\u00a01 ). The particulate organic matter C (POM-C), dissolved organic C (DOC), and microbial biomass C (MBC) levels in the 0\u20135\u00a0cm layer under NT treatment were 155%, 232%, and 63% greater, respectively, compared to the CT treatment. The POM-C, DOC, and MBC in the 5\u201310\u00a0cm layer under NT treatment were 67%, 123%, and 63% greater, respectively, compared to the CT treatment. Below 10\u00a0cm, the labile carbon observed in the NT treatment did not differ from that of the CT treatment. Significantly positive correlations were observed between the SOC and the labile organic C fractions. Moreover, the winter wheat ( T. aestivum L.) yield increased 28.9% in the NT treatment compared to the CT treatment. The data show that NT is an effective and sustainable management practice that improves carbon sequestration and increases soil fertility, resulting in higher winter wheat yields in the rainfed dryland farming areas of northern China.", "keywords": ["2.

It is not fully understood how long term addition of carbon (C) and nitrogen (N) through biomass, farm yard manure (FYM) and inorganic fertilizers are distributed in soil aggregates in a tropical rice\u2013rice system. Therefore, the objectives of this study were to investigate the long-term effects of FYM and inorganic fertilizer in a rice\u2013rice system on (i) distribution of water stable aggregates in the soil, and (ii) amount of total soil organic carbon (TOC), total N and C/N ratio in different aggregate fractions. The total water stable aggregates (WSA) ranged from 71.6% under control to 91.1% under NPK\u00a0+\u00a0FYM in the surface soil (0\u201315\u00a0cm). The incorporation of FYM increased the macroaggregates (5\u20132\u00a0mm) by 165.3% and mesoaggregates by 130.7% (2\u20131\u00a0mm) and 282.8% (1\u20130.5\u00a0mm) over control in 0\u201315\u00a0cm soil layer. Mean weight diameter (MWD), varied from 0.43 to 0.78 in 0\u201315\u00a0cm and from 0.40 to 0.72 in 15\u201330\u00a0cm soil layer. MWD was higher under FYM treated plots than inorganic fertilizer alone and unfertilized control plots. Irrespective of treatment, macroaggregates (5\u20132\u00a0mm) had the highest (4.13\u201314.03\u00a0g\u00a0kg\u2212\u00a01) and microaggregate fraction (0.25\u20130.1\u00a0mm) had the least (3.70\u20138.89\u00a0g\u00a0kg\u2212\u00a01) TOC content in the 0\u201315\u00a0cm soil layer. The application of FYM either alone or in combination with inorganic fertilizers significantly increased the accumulation of TOC in all aggregate fractions over control, however, the effect was more pronounced in macroaggregates fraction 5\u20132\u00a0mm and microaggregate fraction 0.1\u20130.053\u00a0mm. The combined application of inorganic fertilizers and FYM resulted in an increase in total N content which ranged from 0.43 to 1.0\u00a0g\u00a0kg\u2212\u00a01 in 5\u20132\u00a0mm and from 0.09 to 0.44\u00a0g\u00a0kg\u2212\u00a01 in 0.25\u20130.1\u00a0mm aggregate fractions.

A higher C:N ratio was observed in 15\u201330\u00a0cm than 0\u201315\u00a0cm soil layer.

The objective of our study was to determine the longer and short-term impacts of three different tillage treatments (conventional tillage, mulch tillage and no-tillage) on water stable aggregate size distribution. Soils from three sites with long-term tillage trials on loess soils in Germany, planted with sugar beet followed by two years of winter wheat, were sampled in 0\u20135\u00a0cm, 5\u201325\u00a0cm and 25\u201340\u00a0cm depth in April 2010 (wheat stand on all sites), September 2011 (before tillage, after wheat harvest or in the sugar beet), November 2011 (bare soil after tillage or after tillage and sowing of winter wheat) and April 2012 (bare soil or wheat stand). Generally, the soils under no tillage and mulch tillage showed higher yields of macro-aggregates and carbon contents of macro-aggregates in 0\u20135\u00a0cm soil depth than under conventional tillage for all sampling dates, probably mainly due to litter accumulation in the topsoil under reduced tillage treatments. Tillage in November 2011 showed no effect on macro-aggregate yield in comparison to earlier sampling in September 2011. This suggests that either the physical impact of the mouldboard plough did not markedly affect macro-aggregate dynamics or that high macro-aggregate rebuilding rates due to litter incorporation and soil mixing under conventional tillage counterbalanced the physical impact. In 0\u20135\u00a0cm soil depth the carbon content of the micro-aggregates within macro-aggregates was higher under reduced tillage treatments, indicating accelerated macro-aggregate turnover under conventional tillage. In contrast, it was lower in 5\u201325\u00a0cm under no tillage and 25\u201340\u00a0cm under mulch tillage and no tillage than under conventional tillage. Overall, the pattern of yields of macro-aggregates and carbon contents within macro-aggregates over time and depth suggests that the interaction of soil disturbance and litter incorporation of the different tillage treatments created a steady state in terms of macro-aggregate turnover within the different tillage treatments.", "keywords": ["2.

Two chronosequences in the Zhejiang Province, PR China, were investigated; one under paddy cultivation with a maximum soil age of 2000\u00a0years, and the other under upland crops where the oldest soil was 700\u00a0years old. Bulk soils and soil fractions of the uppermost A horizons were analyzed for OC concentrations, radiocarbon ( 14 C) contents, total pedogenic iron oxide concentration and oxalate extractable proportions of iron (Fe OX ) oxides. The specific surface area of soil minerals was measured with the Brunauer\u2013Emmett\u2013Teller (BET-N 2 ) method on four conditions: untreated, after organic matter removal, after iron oxide removal and after removal of both. Initial soil formation on calcareous marine sediments includes soil decalcification and OC accumulation. Paddy soils are characterized by an accelerated decalcification, higher contents of OC and Fe OX oxides, and a pronounced accumulation of modern OC. The mineral constitution of the soil material indicated already a certain degree of weathering since the earliest stages of pedogenesis and remained unchanged in paddy and non-paddy soils. The study provides no evidence of formation of new clay-sized minerals during soil development, which could supply new surfaces for OC accumulation. However, the study revealed higher OC coverage on mineral surfaces in decalcified paddy soils. Therefore, we assume the specific surface area and the specific affinity of Fe OX oxides for OC storage to play an important role for OC accumulation in organo-mineral associations. In contrast, the surface area of minerals in non-paddy soils, in which decalcification and the proportion of Fe OX oxides were much lower, showed significantly lower OC coverage. Selective removal of SOM or iron oxides clearly showed that iron oxides and SOM protect each other in organo-mineral associations primarily in paddy fine clay-sized fraction. Thus, we explained the higher OC coverage on mineral surfaces by complex association between clay minerals, iron oxides and SOM in paddy soils.", "keywords": ["2. Zero hunger", "13.

Recent analyses indicated that 'Redfield-like' ratios existed in plants; such data might provide insight into the nature of nutrient limitation in terrestrial ecosystems. We attempted to determine if analogous C:N:P stoichiometrical ratios exist in the soil and plant in the reed-dominated coastal wetlands of the Yellow River Delta (YRD). Under the influences of anthropogenic cultivation in the YRD, the reed-dominated wetlands could be classified into three categories, new-born wetland (NW), farmland converted into wetland (FW) and cotton wetland (CW). In these three wetland categories, our results showed that atomic C:N:P ratios (R-CNP) in both the soil (42.6:1.6:1, 71.2:2.0:1 and 63.2:1.9:1, respectively) and the plant (1753:22.4:1, 1539:23.0:1 and 1196:23.8:1, respectively) were not well-constrained. Though C:N ratios (R-CN) and C;P ratios (R-CP) were of relatively large variation among different wetland soils and plants, average atomic N:P ratios (R-CN) in both the soil (similar to 1.9:1) and the plant (similar to 23:1) were well-constrained in the reed-dominated wetlands at the YRD scale, suggesting that the N limitation and P limitation were found in the soils and the plants, respectively.

The expansion of tropical forest into savanna may potentially be a large carbon sink, but little is known about the patterns of carbon sequestration during transitional forest formation. Moreover, it is unclear how nutrient limitation, due to extended exposure to fire\uffe2\uff80\uff90driven nutrient losses, may constrain carbon accumulation. Here, we sampled plots that spanned a woody biomass gradient from savanna to transitional forest in response to differential fire protection in central Brazil. These plots were used to investigate how the process of transitional forest formation affects the size and distribution of carbon (C) and nitrogen (N) pools. This was paired with a detailed analysis of the nitrogen cycle to explore possible connections between carbon accumulation and nitrogen limitation. An analysis of carbon pools in the vegetation, upper soil, and litter shows that the transition from savanna to transitional forest can result in a fourfold increase in total carbon (from 43 to 179 Mg C/ha) with a doubling of carbon stocks in the litter and soil layers. Total nitrogen in the litter and soil layers increased with forest development in both the bulk (+68%) and plant\uffe2\uff80\uff90available (+150%) pools, with the most pronounced changes occurring in the upper layers. However, the analyses of nitrate concentrations, nitrate\uffe2\uff80\uff8a:\uffe2\uff80\uff8aammonium ratios, plant stoichiometry of carbon and nitrogen, and soil and foliar nitrogen isotope ratios suggest that a conservative nitrogen cycle persists throughout forest development, indicating that nitrogen remains in low supply relative to demand. Furthermore, the lack of variation in underlying soil type (>20 cm depth) suggests that the biogeochemical trends across the gradient are driven by vegetation. Our results provide evidence for high carbon sequestration potential with forest encroachment on savanna, but nitrogen limitation may play a large and persistent role in governing carbon sequestration in savannas or other equally fire\uffe2\uff80\uff90disturbed tropical landscapes. In turn, the link between forest development and nitrogen pool recovery creates a framework for evaluating potential positive feedbacks on savanna\uffe2\uff80\uff93forest boundaries.

Using nuclear magnetic resonance and near-edge X-ray adsorption fine structure spectroscopy, we found that both C and N became enriched in aromatic and heterocyclic aromatic structures in biochar, and this structural change led to a reduction in C and N mineralization rates. The mineralized C decreased from 32.7% of the added C of raw biomass to <\u00a00.5% of that of biochar at charring temperatures above 400\u00a0\u00b0C. N release shifted from N mineralization in raw biomass to N immobilization at charring temperatures at 500\u00a0\u00b0C. As such, soil amended with biochar produced at charring temperatures exceeding 400\u00a0\u00b0C demonstrated a 25% decrease in dry shoot biomass compared with unamended soil. The results indicated that the C stability of leguminous green manure can be achieved by converting raw material into biochar, but that the charring process may limit it to providing N.", "keywords": ["2.

We measured CH 4 and N 2 O emissions during two cropping seasons in the Philippines from field plots exposed to contrasting treatments during the fallow before land preparation for rice cultivation. The fallow treatments were continuous soil flooding (flooded), soil drying with exclusion of rainfall (dry), soil drying with dry tillage (dry\u00a0+\u00a0tillage), and a control with soil drying and wetting from rainfall (dry and wet). All plots were subdivided into removal of all aboveground rice residues from the previous crop (without residue) and retention of standing biomass after harvest of the previous rice crop (with residue). Emitted gas was collected weekly using chambers. Fallow treatments greatly influenced greenhouse gas (GHG) emissions during rice growth. Methane emissions and global warming potential (GWP) in both cropping seasons were highest following the flooded fallow, intermediate following the dry and wet fallow, and lowest following dry and dry\u00a0+\u00a0tillage fallows. The GWP was higher with than without residue across all fallow treatments. Nitrous oxide emissions were small during the season, and CH 4 emissions contributed more than 90% of the cumulative GWP during the rice crop regardless of fallow and residue management. Soil drying between rice crops in the tropics can reduce CH 4 emissions and GWP during the subsequent rice crop.", "keywords": ["2. Zero hunger", "climate change", "nitrous oxide", "13.

Arctic tundra soils contain a large amount of carbon, which may be vulnerable to decomposition under potential climate change. However, mechanistic understanding of the decomposition process and the consequent changes remains lacking. In the present study, we conducted a manipulation experiment at an arctic soil system in Cambridge Bay, Canada, where temperature and precipitation were increased artificially by installing open top chambers and adding distilled water during growing seasons. After one and half year of environmental manipulation, we investigated extracellular enzyme activities, which are related to decomposition, and analyzed stable isotope signatures (\u03b413C and \u03b415N) in soils and plants, which are related to water and nitrogen availability. Hydrolase (\u03b2- d -glucosidase, cellobiase, N-acetyl-glucosidase and aminopeptidase) activity did not differ significantly under different treatments. However, phenol-oxidase showed higher activity under warming combined with increased precipitation than under other treatments. Stable isotope ratio (\u03b413C) in plants revealed that drought stress in vegetation was induced under warming. We concluded that in the long term, climate change may amplify the feedback of soil to climate change in arctic tundra soil.", "keywords": ["13.

The increase in occurrence in recent decades has raised widespread concern about the impact of repeated wildfires on runoff and erosion, a topic that has not been widely studied. We addressed these concerns in an area of north-central Portugal by comparing runoff at the micro-plot scale and the associated transport of sediments and organic matter (OM) in unburnt, once burnt, and repeatedly burnt plantations of Maritime Pine. We selected nine sites following a large wildfire in September 2012 that affected roughly 3000 ha of the Viseu municipality. Three of the sites had not been burnt since 1975 and acted as controls, with covers of pine trees, shrubs, and annual vegetation; three sites had burnt only in 2012 and contained burnt pines but no shrubs or annual vegetation; and three degraded sites had suffered from three wildfires prior to 2012 and contained no vegetation. We established nine micro-plots (0.25 m2) at each site and collected runoff, eroded soil, and OM losses in tanks after each rain from October 2012 to September 2014. The repeated wildfires strongly increased the runoff coefficient and the risk of downstream flooding after heavy rains. OM losses were nearly half the volume of the eroded soil in the degraded sites due to the transport of ash in the runoff. Runoff and soil losses occurred not only after erosive rainstorms following a fire but also after a subsequent period of drought. Soil cover, rain intensity, and soil moisture were key factors in the amount of runoff and erosion. The insights provided by this study can contribute to pre- and post-fire activities and management in protect areas and can thus improve post-fire recovery.", "keywords": ["Pine plantation", "Runoff", "13.
