Introduced, invasive plants can alter local soil chemistry and microbial communities, but the underlying mechanisms and extent of these changes are largely unknown. Based on characteristics associated with invasiveness in plants, it was hypothesized that introduced species that produce large amounts of litter with distinctive secondary compounds can a) alter the chemistry of both extractable and bulk carbon in the soil, b) shift microbial communities towards microbes better able to metabolize the compounds in the litter, and c) cause soil carbon chemistry and microbial communities to shift to relatively uniform, novel states at multiple sites. 2. Composition of phenolics in senescent tissues (leaves and roots) of Polygonum cuspidatum was compared to the composition of extractable phenolics and non-extractable bulk organic carbon in soils under and adjacent to large, long-established stands of P. cuspidatum at four sites in the eastern U.S. Rates of degradation of phenolics, activities of enzymes associated with the breakdown of phenolics, and shifts in microbial community composition were also measured at the sites. 3. Soils under P. cuspidatum stands contained twice as much phenolics as adjacent soils, but the composition of phenolics differed greatly between soils under stands and senescent tissues of P. cuspidatum. Flavonoids and proanthocyanidins constituted >90% of the identified phenolics in P. cuspidatum tissues, whereas monophenolic compounds accounted for > 90% of the phenolics in soils under stands. Soils under and adjacent to stands also exhibited distinctive compositions of relatively persistent bulk organic carbon; composition differed less between soils under stands at different sites than between soils under and adjacent to stands at the same site. 4. Soils under P. cuspidatum had 2.8 times greater abundance of fungi than soils adjacent to stands, and fungal markers showed clear separation of soils under and adjacent to P. cuspidatum. However, the potential activity of enzymes that degrade polyphenols was lower in soils under stands. Exogenously applied chemically complex polyphenols persisted in both P. cuspidatum invaded and adjacent non-invaded soils, whereas less complex compounds rapidly disappeared from both soils. 5. Synthesis. Results suggest that interactions between plant inputs, abiotic reactions, and biotic transformations may create and maintain new states in invaded soils that are chemically and biologically less diverse. In the case of polyphenol rich, fast growing invasive species, these interactions may alter the composition of bulk soil organic matter that has slower turnover rates, resulting in legacy effects. Restoration could thus require, not just removal of the species, but also post-removal interventions such as soil amendments.", "keywords": ["Flavonoids", "Peroxidases", "Mass spectrometry", "tannins", "Fallopia japonica", "Japanese knotweed", "Reynoutria japonica", "Polyphenols", "home-field advantage", "Legacy effect", "15.

Invasive plant species are key drivers of global environmental changes leading to the disruption of ecosystems they invade. Many invasive species engage in novel niche construction through plant-soil feedbacks facilitated by the input of secondary compounds, which help their further spread and survival. These compounds can persist in soil even after the removal of the invader thus creating a legacy effect that inhibits the return of native flora and fauna. Thus, formulating active intervention strategies that can reverse niche construction is critical for the restoration of these invaded ecosystems. 2. We hypothesized that the management practices that can reverse the soil carbon and nutrient cycling in invaded ecosystems can facilitate the rapid restoration of the invaded sites. We predicted that adding soil C amendments such as activated carbon and biochar can alter the microbial functional activity and nutrient cycling leading to the restoration of invaded habitats. We tested this hypothesis in an old-field in Massachusetts that has been invaded by Japanese knotweed (Polygonum cuspidatum) for >20 years. 3. After two years of treatment application, the activated carbon and biochar amended plots had 80% more biomass of the prairie species than the control plots. The C amendments also altered soil nutrient cycling and fungal biomass and enzyme activity compared to the control plots. The nitrate content of C amended plots was 5 times higher than the non-amended control plots indicating an increased nitrogen mineralization in C amended plots potentially due to the sorption of phenolic compounds by activated carbon and biochar that makes them unavailable. This was further supported by the increased phenol oxidase activity which might have been less inhibited by tannins and led to increased organic matter decomposition. 4. Synthesis and conclusions: Our results thus reveal the potential of soil C amendments in reversing niche construction and legacy effects of polyphenol-rich invasive species and indicate that biochar could be a more economically feasible alternative to activated carbon in restoring invaded ecosystems. Our results also emphasize that understanding the mechanism through which invasive species engage in niche construction is vital in formulating suitable knowledge-based restoration practices for invaded ecosystems.", "keywords": ["2.

This study investigated the effect of the long-term use of cropland and cropland reclamation from natural ecosystems on soil organic carbon (SOC) content and density over the past 35 years. Altogether, 2140 topsoil samples (0\u201320 cm) were collected across Northeast China. Landsat images were acquired from 1985 to 2020 through Google Earth Engine, and the reflectance of each soil sample was extracted from the Landsat image that its time was consistent with sampling. The hybrid model that included two individual SOC prediction models for two clustering regions was built for accurate estimation after k-means clustering. The probability hybrid model, a combination between the hybrid model and classification probabilities of pixels, was introduced to enhance the accuracy of SOC mapping.

Our study, conducted in a 10\u202f000\u202fha landscape in Xishuangbanna, SW China, aimed at assessing the spatial variability in SOC concentrations and stocks, as well as the relationships of SOC with land-use types, soil properties, vegetation characteristics and topographical attributes at three spatial scales: (1) land-use types within a landscape (10\u202f000\u202fha), (2) sampling plots (1\u202fha) nested within land-use types (plot distances ranging between 0.5 and 12\u202fkm), and (3) subplots (10\u202fm radius) nested within sampling plots. We sampled 27 one-hectare plots \u2013 10 plots in mature forests, 11 plots in regenerating or highly disturbed forests, and 6 plots in open land including tea plantations and grasslands. We used a sampling design with a hierarchical structure. The landscape was first classified according to land-use types. Within each land-use type, sampling plots were randomly selected, and within each plot we sampled within nine subplots. SOC concentrations and stocks did not differ significantly across the four land-use types. However, within the open-land category, SOC concentrations and stocks in grasslands were higher than in tea plantations (P\u2009<\u20090.01 for 0\u20130.15\u202fm, P\u2009=\u20090.05 for 0.15\u20130.30\u202fm, P\u2009=\u20090.06 for 0\u20130.9\u202fm depth).

In this montane landscape, variability within plots accounted for more than 50\u202f% of the overall variance in SOC stocks to a depth of 0.9\u202fm and the topsoil SOC concentrations. The relationships of SOC concentrations and stocks with land-use types, soil properties, vegetation characteristics, and topographical attributes varied across spatial scales. Variability in SOC within plots was determined by litter layer carbon stocks (P\u2009<\u20090.01 for 0\u20130.15\u202fm and P\u2009=\u20090.03 for 0.15\u20130.30 and 0\u20130.9\u202fm depth) and slope (P\u2009\u2264\u20090.01 for 0\u20130.15, 0.15\u20130.30, and 0\u20130.9\u202fm depth) in open land, and by litter layer carbon stocks (P\u2009<\u20090.001 for 0\u20130.15, 0.15\u20130.30 and 0\u20130.9\u202fm depth) and tree basal area (P\u2009<\u20090.001 for 0\u20130.15\u202fm and P\u2009=\u20090.01 for 0\u20130.9\u202fm depth) in forests. Variability in SOC among plots in open land was related to the differences in SOC concentrations and stocks between grasslands and tea plantations. In forests, the variability in SOC among plots was associated with elevation (P\u2009<\u20090.01 for 0\u20130.15\u202fm and P\u2009=\u20090.09 for 0\u20130.9\u202fm depth). The scale-dependent relationships between SOC and its controlling factors demonstrate that studies that aim to investigate the land-use effects on SOC need an appropriate sampling design reflecting the controlling factors of SOC so that land-use effects will not be masked by the variability between and within sampling plots.", "keywords": ["Soil organic carbon stocks", "Land-use type", "Soil characteristics", "15.

The study area is located in northern Quebec\u2019s clay plain, within the balsam fir-paper birch (Abies balsamea (Linnaeus) Miller-Betula papyriferaMarshall) bioclimatic domain (Grondin 1996). Climatic conditions are subpolar, subhumid, and continental with an annual average temperature and precipitation of respectively between 1-2 \u00b0C and 825-975 mm according to the Canadian climate normal 1981-2010 station data (Environment Canada, 2023). Forest vegetation mainly consisted of jack pine stands with interspersed stems of Picea mariana (Miller) Britton, Sterns & Poggenburgh, Populus tremuloides Michaux, Betula papyrifera Marshall, Abies balsamea (Linnaeus) Miller, and Acer rubrum Linnaeus. Specifically, the Abitibi region is characterized by natural gradients of soil physicochemical properties, from sandy eskers to clayey soil types. Indeed, esker soils account for ~3% of the Abitibi\u2019s surface while the remainder of the region\u2019s flat topography (~57%) is dominated by clayey soils (Robitaille and Saucier 1998; Cloutier et al. 2007). Abitibi eskers have mineral surface deposits with an overall thickness of more than 25 cm, an illuvial horizon with coarse texture, and a high stone content. Conversely, glacio-lacustrine clayey soils, which are associated with Luvisols or Gleysols in the Abitibi region (Laverdi\u00e8re and De Kimpe 1984; Bergeron et al. 2007), are characterized by an illuvial horizon with medium texture and a low stone content (Blouin and Berger 2002). Site selection Site selection was based on four main criteria, namely soil type (sandy esker/clayey), dominant vegetation (jack pine, minimum 50-75% of canopy cover), stand age (minimum 50-60 years), stand origin (natural fire-origin, totally or mostly unimpacted by anthropogenic disturbance), and accessibility (maximum 350 m from forest roads). We used satellite images and forest inventory data from the Quebec government\u2019s online platform \u2018For\u00eat Ouverte\u2019 for site selection. We selected 18 natural jack pine stands (12 on sandy eskers, 6 on the clay plain). Only six clayey sites fitting our selection criteria were found within the prospected territory due to the scarcity of unmanaged (natural) jack pine stands on clayey soils. Sites were separated by a minimum distance of 5 km to ensure independence between samples and avoid pseudoreplication. Finally, the study design consisted of a first-level factor (soil type) with two levels (sand and clay), and a second-level factor (soil horizons) with three levels (litter, organic, and mineral). Soil sampling Soil samples were collected during the summer of 2022 to characterize soil fungal communities and obtain the physicochemical composition across the soil profile. A circular plot with a 28 m radius and an area of 2,500 m2 was established at each study site, at least 20 m from the forest edge to avoid related variability bias (Dickie and Reich 2005). Within each plot, five jack pine trees were randomly selected (at least 10 m apart), and two soil sample replicates per tree (2-3 m apart) were collected, following a modified protocol by Tedersoo et al. (2014; 2021). Sampling locations around trees were randomly selected with the restriction criteria of being strictly opposite (angle of 180\u00b0). In total, 180 soil cores (2 replicates \u00d7 5 trees \u00d7 18 sites) were collected. For each sampling spot, forest fallen litter (dead leaves, needles) (hereafter referred to as litter horizon) was collected in plastic bags for DNA and physicochemical analyses, followed by samples from the organic layer (hereafter referred to as organic horizon). The latter represented a dark-colored layer rich in organic matter at various decomposition stages, mainly composed of fallen plant material. These organic samples included both F and H horizons. After the removal of the organic layer, we sampled the mineral soil (hereafter referred to as mineral horizon) using a pedological auger (25 cm in length and 7.5 cm in diameter), capturing both eluvial and illuvial horizons. For esker sites, the mineral soil profile was characterized by the formation and accumulation of organo-metallic assemblages, involving Al and Fe elements, in a leached grey eluvial and rust-brown illuvial horizon, respectively. Due to the variable thickness of the eluvial horizons within both esker and clayey soil profiles, the proportion of this horizon in the mineral soil samples varied among sites. Large roots and coarse woody debris were systematically removed from organic and mineral material while sampling. Samples were pooled per horizon for each site, resulting in one composite sample for each horizon. This represents 18 composite samples per horizon for a total of 54 composite soil samples (3 horizons \u00d7 18 sites). Each composite soil samples were divided into two sub-samples: one for eDNA-based soil fungal community analysis and the other for physicochemical analysis. Composite organic and mineral soil samples for eDNA analysis were sieved with a 6 mm mesh in the field, placed in plastic bags, transported in an ice-filled cooler and stored at \u2013 25\u00b0C in the Ecology Research Group of Abitibi RCM (GREMA) laboratory until further processing. Composite litter samples for eDNA analysis were crushed in liquid nitrogen using a mortar and pestle prior to DNA extraction. Composite soil samples for physicochemical analyses were sieved with a 4 mm mesh using an automatic vibrating sieve AS 200 Control (ATS Care Retsch, Haan, Germany) after being forced-air dried at room temperature for 14 days to facilitate the sieving process. Soil physicochemical analyses Composite soil samples (> 50g) were sent to the organic and inorganic chemistry laboratory of the Forest Research Direction (Quebec, QC, Canada) for physicochemical analysis. Total nitrogen (N) and carbon (C) contents were determined by combustion using a CN 928 elemental analyzer (LECO Corp., St Joseph, MI, USA) with thermal conductivity detection for nitrogen and non-dispersive infra-red (NDIR) cell detection for carbon. Organic matter content (hereafter OM) and percentage of humidity (hereafter humidity) were determined by incineration, a method commonly referred to as the loss on ignition (LOI) method (Davies 1974). Soil pH was measured using 10 g of soil mixed with 20 mL of distilled water with an Orion VersaStar Pro pH meter (Thermo Fisher Scientific Inc., Pittsburgh, PA, USA). Elements (P, K, Ca, Mg, Mn, Zn, Al, Fe) were extracted using the Mehlich-III method (Mehlich 1984) and measured by plasma atomic emission spectroscopy (Optima 8300 model, ICP-OES, Perkin Elmer, Waltham, MA, USA). Particle size distribution and textural class determination were performed on soil samples consisting of fine earth (<2 mm) containing 5% or less carbon using the Bouyoucos method (Bouyoucos 1962). DNA extraction, amplification and library preparation DNA extraction was carried out at the Environmental Genomic Laboratory of the Laurentian Forestry Centre (EGL-CFL) on 150 mg of composite litter and organic samples, and 250 mg of composite mineral samples using a DNeasy powersoil pro kit (Qiagen, Valencia, CA, US) and the QIAcube automated instrument (Qiagen, Hilden, Germany) in accordance with the manufacturer\u2019s instructions. DNA was quantified with the Qubit\u2122 dsDNA BR Assay Kit (Thermo Fisher Scientific Inc, Wilmington, USA). Fungal DNA amplicon libraries were prepared at the EGL-CFL following a previously described procedure (Samad et al. 2023) and sequenced on an Illumina MiSeq platform at the Next Generation Sequencing Platform of the CHU de Qu\u00e9bec-Universit\u00e9 Laval Research Centre using a MiSeq v3 600-cycle Reagent Kit. Even though one ITS region contains less genetic information than the entire ITS (Tedersoo et al. 2022), the ITS2 region of the fungal ribosomal DNA was amplified using the primer set ITS9F (5\u2019-GAACGCAGCRAAIIGYGA-3\u2019) and ITS4R (5\u2019-TCCTCCGCTTATTGATATGC-3\u2019 (White et al. 1990; Ihrmark et al. 2012; Rivers 2016) because of limitations to sequence length that can be obtained with Illumina Sequencing. Negative controls in the DNA extraction and PCR amplification were used to control potential contaminants during the process. Bioinformatic and sequence analyses All bioinformatics analyses were performed in QIIME2 v2023.2.0 (Bolyen et al. 2019). Demultiplexed FASTQ (R1 and R2) files were first imported in QIIME2 using the \u2018qiime import\u2019 command which converts the data into a QZA archive file so it can be processed by the rest of the QIIME2 workflow. First, primers were removed using the QIIME2 implementation of CutAdapt (Martin 2011). Resulting forward and reverse reads went through the DADA2 (Callahan et al. 2016) pipeline for sequence quality control and feature table construction using the \u2018\u2019qiime dada2 denoise-paired\u2019\u2019 command. During this process, low-quality regions of the sequences were trimmed, paired reads assembled, chimeric sequences filtered, remaining high-quality sequences dereplicated, and singletons and very low-frequency abundance ASVs removed using the \u201cqiime feature-table filter-features\u201d command. The output of this step was a feature table (i.e., ASV table) which contains read counts for each unique sequence in each sample of the dataset, and feature data which contains sequences corresponding to each ASV. A taxonomy was assigned to each ASV based on the UNITE reference database (version 9.0) (Abarenkov et al. 2010, 2023; K\u00f5ljalg et al. 2005, 2013; Nilsson et al. 2019b) using the \u2018\u2018classify-sklearn\u2019\u2019 with a Naive Bayes classifier.

The mean annual temperature is around 15\u00b0C and the mean annual rainfall is 885 mm (Soriano and Paruelo 1992). The landscape has a treeless physiognomy and an extremely flat topography with periodic flooding during autumn\u2013spring in lowland, except in ridge areas with well-drained sandy soils (Burkart et al. 1998). The field experiment was carried out in a commercial livestock farm (35\u00b0 01\u00b4S, 57\u00b0 50\u00b4 W). The plant community is dominated by C3 and C4 grass species (see details in Druille et al. 2015). Soil is classified as a typical Natracuol (US Soil Taxonomy), characterized by having a nonsaline acid A1 horizon, and a highly alkaline saline B2 horizon (Lavado and Taboada 1988). Glyphosate was not applied at the study site before, even though glyphosate application in the late summer is a common practice in the region with a 3 l/ha dose (Rodriguez and Jacobo 2010). We applied this dose (1440 g of acid equivalent/ha) of a commercial glyphosate formulation Glacoxan\u00ae in field and greenhouse experiments with a 20 l backpack sprayer with a constant pressure of 3 bars. Pathways of single-glyphosate application To evaluate pathways of single application of glyphosate effects through living plants (1), leaf litter (2), and soil (3), we set up a litter decomposition experiment in a greenhouse. For these pathways, we used plant material that is naturally found in the field at the end of the summer when glyphosate is applied in the Flooding Pampa. At that time of the year, Paspalum dilatatum, the native dominant perennial C4 grass, can be found as a living plant and as plant litter. In turn, Lolium multiflorum, which is an introduced annual winter C3 forage grass, is only found dead as plant litter. Considering that in this grassland the vast majority of L. multiflorum plants are endophyte-infected with Epichlo\u00eb occultans (Gundel et al. 2009), in this experiment we used L. multiflorum plants associated with the endophyte. Together, for the living plant pathway we used P. dilatatum (1) and for the leaf litter pathway (2) we used litter produced by P. dilatatum and L. multiflorum with endophyte plants. Paspalum dilatatum and Lolium multiflorum plants were grown in 1 m x 1 m monoculture plots in the experimental campus of the School of Agronomy at the University of Buenos Aires. L. multiflorum plants grew from seeds with naturally high level (82%) of endophyte association (E+), and from seeds without endophyte (E-) obtained experimentally following Omacini et al. (2004). We collected fresh senesced plant litter of both species and, in the lab, sorted leaf litter from other plant organs. Then, in the P. dilatatum plots, we removed all dead plant material to applied glyphosate on living plants. After 15 days, we collected P. dilatatum plants killed by glyphosate and separated the leaf litter from other organs. We determined the total carbon (%C) and nitrogen (%N) content of all types of litter by Dumas combustion with a TruSpec elemental analyzer (LECO, St. Joseph, MI, USA) at the University of Buenos Aires. We prepared litterbags containing leaf litter from P. dilatatum plants killed by glyphosate (Plant Gx) and from naturally senesced P. dilatatum and L. multiflorum E+ plants. Litterbags were made of fiberglass mesh, which is the most common used material for litter decomposition studies (Harmon et al. 1999, Bradford et al. 2002), and that we have successfully used before (Omacini et al. 2004, Vivanco and Austin 2006, 2019).\u00a0 We used 0.5 g of each litter type in 11 cm x 9 cm litterbags with a 3 mm opening on the upper face and a 2 mm opening on the lower face. We prepared plastic containers with 1.2 kg of soil from the study site, which had not received prior glyphosate treatment. Half of the litterbags containing naturally senesced leaves were sprayed with glyphosate (Litter G+) and the other half was sprayed with water (Litter G-). Half of the soil containers were sprayed with glyphosate (Soil G+) and the other half was sprayed with water (Soil G-). We assigned litterbags (Plant Gx, Litter G+, Litter G-) to soil containers (Soil G+, Soil G-) in a factorial design and kept them moistened with regular watering (n=5). We assessed litter decomposition as litter mass loss over time. We collected litterbags after 140 and 270 days of incubation. Litterbags were dried for 48 h at 65\u00b0C; soil and debris were removed from litter and were oven-dried again for determination of dry mass. We estimated the decomposition constant k using a single exponential decay model by regressing the log of the fraction of mass remaining against time. The decomposition constant integrates the dynamics of litter mass loss over time and it is a useful parameter to compare between litter types and treatments (Wieder and Lang 1982). We used ln (Mt/Mo) = \u2013kt, where Mo is the initial dry mass, Mt is the dry mass at time t, and k is the decomposition constant (Swift et al. 1979). Linear regressions were performed by setting the intercept to zero. In the few cases when samples did not fit a significant regression, values were considered outliers and were replaced by the mean of the treatment, following the missing value procedure (Steel and Torrie 1980, Vivanco and Austin 2008). Pathways of repeated annual application of glyphosate in natural grasslands We evaluated pathways of repeated annual application of glyphosate through legacies in ecosystem properties (4) and through the enhancement of endophytic grass (5) (Fig. 1) on decomposition of leaf litter and roots in a field experiment in the Flooding Pampa. In this field experiment, we previously studied the impacts of glyphosate application on beneficial soil microorganisms (Druille et al. 2013, 2015, 2016). We established 10 plots (1.5m x 1.5 m) in an area of similar floristic composition and randomly assigned them to control (Ecosystem G-) or glyphosate application (Ecosystem G+) treatments. Every April (late summer in the southern hemisphere) for three consecutive years, we applied 3 l / ha of water to Ecosystem G- plots and 3 l / ha (1440 g acid equivalent / ha) of commercial glyphosate formulation (Glacoxan\u00ae) to Ecosystem G+ plots. We applied these treatments using a 20 l backpack sprayer with a constant pressure of 3 bars. Cattle grazing was avoided during the experiment by keeping an electric wire around the experimental area. To avoid biomass accumulation and the consequent aging of grasslands, we made a harvest of plant biomass using a lawn mower set to leave 10 cm stubble every year before application of the treatment. To evaluate pathways of repeated annual application of glyphosate, we used litter produced by plants of L. multiflorum with (E+) and without (E-) endophyte that was accumulated above and below ground (leaf and root litter). We prepared 14 cm x 14 cm litterbags made of 2 mm fiberglass mesh. We placed leaf litterbags on the ground and root litterbags buried 5 cm belowground. Considering that the place where the litter was deposited (above and belowground) can interact with the type of litter (leaf and root litter), we placed a common substrate (stem litter) litterbags on the ground and buried at 5 cm to assess the effects of the above and belowground environment. The experiment started 15 days after the third year of application of glyphosate (n = 4) and we collected litterbags at 30, 140 and 260 days. We assessed ash-free dry mass (500\u00b0C oven for 4 h) to estimate the decomposition constant k as described in Section 2.3. Together, this experiment evaluated the relative importance of pathways 4 and 5 and provides information about the effect of an aerial symbiosis on root decomposition of the host, which has not been evaluated previously. We assessed above and belowground ecosystem properties in Ecosystem G- and Ecosystem G+ plots. We measured plant cover in December (when the last litterbag pickup occurred) in 10 plots of each level of glyphosate application. For estimation of plant cover, we used the line intercept method proposed by Canfield (1941). We determined potential water evaporation at ground level by measuring the water loss of wet filter papers. We used preweighted oven-dried filter papers and wet them in the field to full water-holding capacity. Filter papers were weighed immediately before and after incubation on the ground for 1 hour at midday in May to calculate water loss. We measured two filter papers per plot in 5 replicates for each level of glyphosate application. We determined soil gravimetric water content from 10 cm depth soil cores taken in August and December (second and third litterbag harvest dates, respectively). We also determined soil organic matter content and soil potential respiration from soil cores taken in May, approximately one year after the decomposition experiment was installed in the field. Soil organic matter content was determined by total combustion in an oven at 500\u00b0C for 4 hours. We determined soil potential respiration by incubating a 15-g sample at 25\u00b0C, in a 200-ml vial with gastight septum caps. The soil was pre-incubated at water field capacity for 48 h without seedlings or any plants. CO2 production was measured 2, 4 and 7 days after a 24-h incubation period with an infrared gas analyzer (PP Systems EGM-4, Amesbury, Massachusetts, USA). We used five replicates per level of glyphosate application for soil measurements.", "keywords": ["2.

Soil microorganisms play a key role in soil biogeochemical cycles, but their growth and activities are often limited by resource availability. Understanding soil processes that are driven by microorganisms and resource limitation of microbes will help to elucidate controls on soil fertility and improve the ability to predict the responses of an ecosystem to global changes. As a widespread ecosystem type, karst ecosystem develops from limestone or dolomite with unique soil, however, karst ecosystems remains poorly understood regarding their soil microbial processes and microbial resource limitation. 2. Here, ecoenzymatic stoichiometry was used as an indicator of microbial resource limitation, and to model major microbial processes (i.e., decomposition of soil organic carbon and microbial respiration) in a karst and a non-karst forest. 3. Results showed that the modeled decomposition and respiration rates were significantly higher in the karst forest than in the non-karst forest. In addition, results of ecoenzymatic stoichiometry showed that the karst forest was more carbon-limited than the non-karst forest. In contrast, the karst forest was likely saturated with nitrogen, but the non-karst forest was limited by nitrogen. Both the karst and non-karst forests were limited by phosphorus, but phosphorus deficiency was more evident in the non-karst forest than in the karst forest. 4. These findings highlight the specific profiles of karst ecosystems, and they suggest that the responses of karst ecosystems to global changes should be very different compared to other ecosystems.", "keywords": ["nutrient limitation", "C limitation", "ecoenzymatic stoichiometry", "calcareous soil", "13.

Freshwater systems play an active role in the carbon cycle as it receives, and decomposes, terrestrial litter material alongside decomposing aquatic plant litter. Decomposition of organic matter in the aquatic environment is directly controlled by water temperature and nutrient availability, which are continuously affected by global change. We adapted the Tea Bag Index (TBI), a highly standardized methodology for determining soil decomposition, for lakes by incorporating a leaching factor. By placing Lipton pyramid tea bags in the aquatic environment for 3 hours, we quantified the period of intense leaching which usually takes place prior to litter (tea) decomposition. Standard TBI methodology was followed after this step to determine how fast decomposition takes place (decomposition rate, k1) and how much of the material cannot be broken down and is thus sequestered (stabilization factor, S). A Citizen Science project was organized to test the aquatic TBI in 40 European lakes located in four climate zones, ranging from oligotrophic to hypereutrophic systems. We expected that warmer and/or eutrophic lakes would have a higher decomposition rate and a more efficient microbial community resulting in less tea material to be sequestered. The overall high decomposition rates (k1) found confirm the active role lakes play in the global carbon cycle. Across climate regions the lakes in the warmer temperate zone displayed a higher decomposition rate (k1) compared to the colder lakes in the continental and polar zones. Across trophic states, decomposition rates were higher in eutrophic lakes compared to oligotrophic lakes. Additionally, the eutrophic lakes showed a higher stabilization (S), thus a less efficient microbial community, compared to the oligotrophic lakes, although the variation within this group was high. Our results clearly show that the TBI can be used to adequately assess the decomposition process in aquatic systems. Using \u201calien standard litter\u201d such as tea provides a powerful way to compare decomposition across climates, trophic states and ecosystems. By providing standardized protocols, a website, as well as face to face meetings, we also showed that collecting scientifically relevant data can go hand in hand with increasing scientific and environmental literacy in participants. Gathering process-based information about lake ecosystems gives managers the best tools to anticipate and react to future global change. Furthermore, combining this process-based information with citizen science, thus outreach, is in complete agreement with the Water Framework Directive goals as set in 2010.", "keywords": ["decomposition constant", "Verwerkte data", "European lakes", "european lakes", "Carbon cycle", "15.

Despite the acknowledged importance of such ecological subsidies, surprisingly little information is available regarding the role of environmental temperature in influencing subsidy quality and the response of the recipient ecosystem. We evaluated the impacts of temperature-mediated changes in leaves from deciduous trees, an important subsidy from terrestrial to freshwater ecosystems, on both the producer-based and detritivore-based components of a pelagic pond food web in a field mesocosm experiment. We hypothesized that variation in leaf chemistry driven by increased soil temperature would alter both the quality of leaf subsidies and the pond response. We collected red maple Acer rubrum leaves from heated and ambient temperature plots from the long-term soil warming experiment at the Harvard Experimental Forest and added them to 167-l field mesocosms containing established plankton communities, creating \u2018no leaf\u2019, \u2018ambient leaf\u2019 and \u2018heated leaf\u2019 treatments during autumn 2012. We then monitored physical, chemical, and biological responses to treatments until the mesocosms froze six weeks later. Experimental soil warming altered the chemical composition of deciduous leaves, the physical and chemical environment of the aquatic ecosystems to which leaves were added, and the pelagic pond food webs as measured by community composition. Compared to leaves from ambient-temperature soils, leaves from warmed soils initially resulted in lower water column phosphorus and dissolved organic carbon, reducing bacterial densities. However, the diminished carbon and phosphorus resulting from soil warming also increased light availability that ultimately stimulated cladoceran zooplankton relative to ambient-temperature leaves.

The various CC species that belong to distinct plant functional types (PFTs) may differentially impact SOC formation and stabilization. Biogeochemical theory suggests that selection of PFTs with distinct litter quality (C:N ratio) should influence the pathways and magnitude of SOC sequestration. Yet, we lack knowledge on the effect of CCs from different PFTs on the quantity and composition of physiochemical pools of SOC. We sampled soils under monocultures of three CC PFTs (legume [crimson clover]; grass [triticale]; and brassica [canola]) and a mixture of these three species, from a long-term CC experiment in Pennsylvania, USA. We measured C content in bulk soil and C content and composition in contrasting physical fractions: particulate organic matter, POM; and mineral-associated organic matter, MAOM. The bulk SOC content was higher in all CC treatments compared to the fallow. Compared to the legume, monocultures of grass and brassica with lower litter quality (wider C:N) had higher proportion of plant-derived C in POM, indicating selective preservation of complex structural plant compounds. In contrast, soils under legumes had greater accumulation of microbial-derived C in MAOM. Our results for the first time, revealed that the mixture contributed to a higher concentration of plant-derived compounds in POM relative to the legume, and a greater accumulation of microbial-derived C in MAOM compared to monocultures of grass and brassica. Mixtures with all three PFTs can thus increase the short- and long-term SOC persistence balancing the contrasting effects on the chemistries in POM and MAOM imposed by monoculture CC PFTs. Thus, despite different cumulative C inputs in CC treatments from different PFTs, the total SOC stocks did not vary between CC PFTs, rather PFTs impacted whether C accumulated in POM or MAOM fractions. This highlights that CCs of different PFTs may shift the dominant SOC formation pathways (POM vs. MAOM), subsequently impacting short- and long-term SOC stabilization and stocks. Our work provides a strong applied field test of biogeochemical theory linking litter quality to pathways of C accrual in soil.", "keywords": ["2.

Yet, there is little understanding of soil organic carbon (SOC) sequestration processes during tropical forest succession, particularly after land abandonment from agriculture practices. Here we used vegetation and environmental data from two large-scale surveys covering a total landscape area of 20,000 ha in Southeast Asia to investigate the effects of plant species diversity, functional trait diversity, phylogenetic diversity, aboveground biomass, and environmental factors on SOC sequestration during forest succession. We found that functional trait diversity plays an important role in determining SOC sequestration across successional trajectories. Increases in SOC carbon storage were associated with indirect positive effects of species diversity and succession age via functional trait diversity, but phylogenetic diversity and aboveground biomass showed no significant relationship with SOC stock. Furthermore, the effects of soil properties and functional trait diversity on SOC carbon storage shift across elevation. Synthesis: Our results suggest that reforestation and restoration management practices that implement a trait-based approach by combining long-lived and short-lived species (conservative and acquisitive traits) to increase plant functional diversity could enhance SOC sequestration for climate change mitigation and adaptation efforts, as well as accelerate recovery of healthy soils.", "keywords": ["2.

Accounting for 10-30% of global soil organic carbon, grassland soils potentially present a large reservoir for storing atmospheric CO2. Livestock grazing management can substantially affect grassland soil carbon (C) storage, but few controlled experiments have explored how herbivore assemblages (different herbivore species and combinations) affect soil C storage. 2. We examined effects of moderate grazing by different herbivore assemblages (no grazing; sheep grazing; cattle grazing; mixed grazing by sheep and cattle) on soil organic carbon storage in two types of grassland communities (high forbs/high diversity and low forbs/low diversity), within a semi-arid grassland with a five-year grazing history. 3. We found that herbivore assemblage generated varying effects on soil C storage and the effects were subject to grassland community types. In the low diversity community, none of three herbivore assemblages studied had obvious effects on soil C storage. In the high diversity community, however, sheep grazing significantly decreased soil C storage due to high selectivity for high quality forbs, and cattle grazing had no effects on soil C storage, while mixed grazing by sheep and cattle significantly increased soil C storage. Overall, soil C storage was highest in mixed-grazed grassland sites with high diversity. 4. Synthesis and applications. Our study suggests that explicitly incorporating grazer species and the combination of grazing livestock into grassland grazing management may help mitigate greenhouse gas emissions. Caution should be exercised when using grazer species with high food selectivity when grazing management is also aimed at climate mitigation, especially in grasslands with abundant high quality forbs and high plant diversity, as sheep grazing may reduce soil carbon (C) storage. Moreover, mixed grazing, including multiple herbivore species, may contribute to a reduction in foraging selectivity for a plant community by means of complementary foraging.

Long-term grazing exclusion significantly increased species richness and seed density in the soil seed bank, but significantly decreased belowground species evenness.

Exclusion of grazing significantly decreased seed depletion in soil seed bank from April to July as compared to grazed sites.

However, all the studies carried out so far have been performed on uncontaminated marble. Unfortunately, this is rarely the case in the field, because marble artifacts exposed outdoors are often affected by sulfation, i. e. formation of a gypsum crust on the surface. Because gypsum is much more soluble than calcite, the outcome of the ammonium phosphate treatment is expected to be sensibly altered by the presence of gypsum. Therefore, in this study the nature and morphology of the new calcium phosphate phases formed by reacting gypsum with aqueous solutions of diammonium hydrogen phosphate (DAP) were investigated. In particular, the effect of DAP concentration, ethanol addition (aimed at reducing gypsum solubility), and pH were explored. The result is that phase formation can be controlled by suitably tuning the above mentioned parameters. Phases with low solubility (such as tricalcium phosphate and hydroxyapatite) can be obtained by increasing the ethanol concentration, the DAP concentration or the pH. However, their formation is associated with diffused cracking, likely because of excessive growth of the new phases. Among the investigated formulations, treatment with a 0.1 M DAP solution with 30 vol % ethanol at pH=8 seems to be the most suitable one, as it leads to formation of brushite (about 30 times less soluble than gypsum), without cracking, so that a reduction in gypsum solubility in rain is expected.", "keywords": ["Marble; Gypsum; Black crusts; Hydroxyapatite; Protection", "13.

Abstract. The particle size distribution (PSD) of mineral dust has a strong effect on the impacts of dust on climate. However, our understanding of the emitted dust PSD, including its variability and the fraction of super-coarse dust (diameter >10\u2009\u00b5m), remains limited. Here, we provide new insights into the size-resolved dust emission process based on a field campaign performed in the Moroccan Sahara in September\u00a02019 in the context of the FRontiers in dust minerAloGical coMposition and its Effects upoN climaTe (FRAGMENT) project. The obtained dust concentration and diffusive flux PSDs show significant dependencies upon the friction velocity (u*), wind direction and type of event (regular events versus haboob events). For instance, the number fraction of sub-micrometre particles increases with u*, along with a large decrease in the mass fraction of super-coarse dust. We identify dry deposition, which is modulated by u* and fetch length, as a potential cause for this PSD variability. Using a resistance model constrained with field observations to estimate the dry deposition flux and thereby also the emitted dust flux, we show that deposition could represent up to \u223c90\u2009% of the emission of super-coarse particles (>10\u2009\u00b5m) and up to \u223c65\u2009% of the emission of particles as small as \u223c5\u2009\u00b5m in diameter. Importantly, removing the deposition component significantly reduces the variability with u* in the PSD of the emitted dust flux compared with the diffusive flux, particularly for super-coarse dust. The differences between regular and haboob event concentration and diffusive flux PSDs are suspected to result from a smaller and variable dust source fetch during the haboob events, and/or an increased resistance of soil aggregates to fragmentation associated with the observed increase in relative humidity along the haboob outflow. Finally, compared to the invariant emitted dust flux PSD estimated based on brittle fragmentation theory, we obtain a substantially higher proportion of super-micrometre particles in the dust flux. Overall, our results suggest that dry deposition needs to be adequately considered to estimate the emitted PSD, even in studies limited to the fine and coarse size ranges (<10\u2009\u00b5m).

Abstract. We quantify the reductions in primary emissions due to the COVID-19 lockdowns in Europe. Our estimates are provided in the form of a dataset of reduction factors varying per country and day that will allow the modelling and identification of the associated impacts upon air quality. The country- and daily-resolved reduction factors are provided for each of the following source categories: energy industry (power plants), manufacturing industry, road traffic and aviation (landing and take-off cycle). We computed the reduction factors based on open-access and near-real-time measured activity data from a wide range of information sources. We also trained a machine learning model with meteorological data to derive weather-normalized electricity consumption reductions. The time period covered is from 21\u00a0February, when the first European localized lockdown was implemented in the region of Lombardy (Italy), until 26\u00a0April 2020. This period includes 5\u00a0weeks (23\u00a0March until 26\u00a0April) with the most severe and relatively unchanged restrictions upon mobility and socio-economic activities across Europe. The computed reduction factors were combined with the Copernicus Atmosphere Monitoring Service's European emission inventory using adjusted temporal emission profiles in order to derive time-resolved emission reductions per country and pollutant sector. During the most severe lockdown period, we estimate the average emission reductions to be \u221233\u2009% for NOx, \u22128\u2009% for non-methane volatile organic compounds (NMVOCs), \u22127\u2009% for SOx and \u22127\u2009% for PM2.5 at the EU-30 level (EU-28 plus Norway and Switzerland). For all pollutants more than 85\u2009% of the total reduction is attributable to road transport, except SOx. The reductions reached \u221250\u2009% (NOx), \u221214\u2009% (NMVOCs), \u221212\u2009% (SOx) and \u221215\u2009% (PM2.5) in countries where the lockdown restrictions were more severe such as Italy, France or Spain. To show the potential for air quality modelling, we simulated and evaluated NO2 concentration decreases in rural and urban background regions across Europe (Italy, Spain, France, Germany, United-Kingdom and Sweden). We found the lockdown measures to be responsible for NO2 reductions of up to \u221258\u2009% at urban background locations (Madrid, Spain) and \u221244\u2009% at rural background areas (France), with an average contribution of the traffic sector to total reductions of 86\u2009% and 93\u2009%, respectively. A clear improvement of the modelled results was found when considering the emission reduction factors, especially in Madrid, Paris and London where the bias is reduced by more than 90\u2009%. Future updates will include the extension of the COVID-19 lockdown period covered, the addition of other pollutant sectors potentially affected by the restrictions (commercial and residential combustion and shipping) and the evaluation of other air quality pollutants such as O3 and PM2.5. All the emission reduction factors are provided in the Supplement.

Evaluating the Poisson hypothesis for rainfall estimation using intervalometers: results from an experiment in Tanzania", "description": "

Abstract. A new type of rainfall sensor (the intervalometer), which counts the arrival of raindrops at a piezo electric element, is implemented during the Tanzanian monsoon season alongside tipping bucket rain gauges and an impact disdrometer. The aim is to test the validity of the Poisson hypothesis underlying the estimation of rainfall rates using an experimentally determined raindrop size distribution parameterisation based on Marshall and Palmer (1948)'s exponential one. These parameterisations are defined independently of the scale of observation and therefore implicitly assume that rainfall is a homogeneous Poisson process. The results show that 28.3\uffe2\uff80\uff89% of the total intervalometer observed rainfall patches can reasonably be considered Poisson distributed and that the main reasons for Poisson deviations of the remaining 71.7\uffe2\uff80\uff89% are non-compliance with the stationarity criterion (45.9\uffe2\uff80\uff89%), the presence of correlations between drop counts (7.0\uffe2\uff80\uff89%), particularly at higher arrival rates (\uffcf\uff81a>500\uffe2\uff80\uff89m-2s-1), and failing a \uffcf\uff872 goodness-of-fit test for a Poisson distribution (17.7\uffe2\uff80\uff89%). Our results show that whilst the Poisson hypothesis is likely not strictly true for rainfall that contributes most to the total rainfall amount, it is quite useful in practice and may hold under certain rainfall conditions. The parameterisation that uses an experimentally determined power law relation between N0 and rainfall rate results in the best estimates of rainfall amount compared to co-located tipping bucket measurements. Despite the non-compliance with the Poisson hypothesis, estimates of total rainfall amount over the entire observational period derived from disdrometer drop counts are within 4\uffe2\uff80\uff89% of co-located tipping bucket measurements. Intervalometer estimates of total rainfall amount overestimate the co-located tipping bucket measurement by 12\uffe2\uff80\uff89%. The intervalometer principle shows potential for use as a rainfall measurement instrument.

Abstract. A novel reference absorption instrument based on photothermal interferometry \u2013 the dual-wavelength photothermal aerosol absorption monitor PTAAM-2\u03bb \u2013 and scattering measurements are used to characterize filter photometer artifacts in measurements of absorption coefficients of soot- and dust-dominated aerosol samples within laboratory and ambient campaigns. We provide, for different aerosol types, reference values of the multiple-scattering parameter, quantifying the artifact introduced by the interaction between the light, the particles, and the filter. The Aethalometer AE33 and the Continuous Light Absorption Photometer (CLAP) were characterized during a laboratory campaign where different soot and mineral dust samples were measured. Furthermore, ambient measurements during a campaign in Granada, Spain, were used to characterize the AE33 and MAAP (Multiangle Absorption Photometer), a pseudo-reference absorption instrument. The laboratory campaign showed significant wavelength dependence of the calibration parameter, the multiple-scattering parameter C. The C of the AE33 at 450 and 808\u2009nm was 4.08 and 3.95 and 6.25 and 5.27 for propane soot and diesel soot, respectively. For the CLAP, the C was 5.10 and 4.26 and 6.79 and 5.80 for propane and diesel soot, respectively. For the different mineral dust samples analyzed in the laboratory, the C at 450\u2009nm ranged between 2.74 and 3.03 for the AE33 and between 2.50 and 2.80 for the CLAP. The ambient measurements at Granada showed an overall C of 4.72 at 450\u2009nm and of 3.90 at 808\u2009nm for the AE33. The results for both the AE33 and the CLAP show a dependence with the particle size, with fine particles having the highest C values and with the C being reduced and leveling off for larger particles. Both the laboratory and the ambient measurements of the AE33 showed overlapping results. The cross-sensitivity to scattering was smaller for the CLAP than for the AE33. The values of the cross-sensitivity parameter ms at 450 and 808\u2009nm were 3.0\u2009% and 1.5\u2009% for the AE33 and 2.4\u2009% and 0.9\u2009% for the CLAP. The intercomparison of the MAAP with the PTAAM-2\u03bb during the ambient campaign in Granada showed that the MAAP overestimates the absorption coefficients for 47\u2009% at 637\u2009nm and features a cross-sensitivity to scattering of 2.4\u2009%.

Abstract. Solar-induced fluorescence (SIF) data from satellites are increasingly used as a proxy for photosynthetic activity by vegetation, and as a constraint on gross primary production. Here we develop an improved retrieval algorithm to retrieve mid-morning (09:30 hrs local time) SIF estimates on the global scale from GOME-2 sensor on the Metop-A satellite (GOME-2A) for the period 2007\uffe2\uff80\uff932019. Our new SIFTER v2 algorithm improves over a previous version by using a narrower spectral window that avoids strong oxygen absorption and is less sensitive to water vapour absorption, by constructing stable reference spectra from a 6-year period (2007\uffe2\uff80\uff932012) of atmospheric spectra over the Sahara, and by applying a latitude-dependent zero-level adjustment that accounts for biases in the data product. We generated stable, good-quality SIF retrievals between January 2007 and June 2013, when GOME-2A degradation in the near infrared was still limited. After the narrowing of the GOME-2A swath in July 2013, we characterized the throughput degradation of the level-1 data in order to derive reflectance corrections and apply these for the SIF retrievals between July 2013 and December 2018. SIFTER v2 data compares well with the independent NASA v2.8 data product. Especially in the evergreen tropics, SIFTER v2 no longer shows the underestimates against other satellite products that were seen in SIFTER v1. The new data product includes uncertainty estimates for individual observations, and is best used for mostly clear-sky scenes, and when spectral residuals remain below a certain spectral autocorrelation threshold. Our results support the use of SIFTER v2 data to be used as an independent constraint on photosynthetic activity on regional to global scales.

Abstract. Plant shoots can act as sources or sinks of trace gases including methane and nitrous oxide. Accurate measurementsof these trace gas fluxes require enclosing of shoots in closed non-steady state chambers. Due to plant physiological activity, this type of enclosures, however, lead to CO2 depletion in the enclosed air volume, condensation of transpired water, and warmingof the enclosures exposed to sunlight, all of which may bias the flux measurements. Here, we present PlasTraGAS, ab novel measurement system designed for continuous and automated measurements of trace gas and volatile organic compound (VOC) fluxes from plant shoots. The system uses transparent shoot enclosures equipped with Peltier cooling elements and automatically replaces fixated CO2 and removes transpired water from the enclosure. The system is designed for measuring trace gasfluxes over extended periods, capturing diurnal and seasonal variations and linking trace gas exchange to plant physiologicalfunctioning and environmental drivers. Initial measurements show daytime CH4 emissions two pine shoots of 0.056 and 0.089 nmol g\uffe2\uff88\uff921 foliage d.w.h\uffe2\uff88\uff921or 7.80 and 13.1 nmol m\uffe2\uff88\uff922 h\uffe2\uff88\uff921. Simultaneously measured CO2 uptake rates were 9.2 and 7.6 mmol m\uffe2\uff88\uff922 sec\uffe2\uff88\uff921 and transpiration rates of 1.24 and 0.90 mol m\uffe2\uff88\uff922 h\uffe2\uff88\uff921. Concurrent measurement of VOC emissionsdemonstrated that potential effects of spectral interferences on CH4 flux measurements were at least ten-fold smaller than themeasured CH4 fluxes. Overall, this new system solves multiple technical problems that so far prevented automated plant shoottrace gas flux measurements, and holds the potential for providing important new insights into the role of plant foliage in the global CH4 and N2O cycles.

Abstract. Ceilometer lidars are used for cloud base height detection, to probe aerosol layers in the atmosphere (e.g. detection of elevated layers of Saharan dust or volcanic ash), and to examine boundary layer dynamics. Sensor optics and acquisition algorithms can strongly influence the observed attenuated backscatter profiles; therefore, physical interpretation of the profiles requires careful application of corrections. This study addresses the widely deployed Vaisala CL31 ceilometer. Attenuated backscatter profiles are studied to evaluate the impact of both the hardware generation and firmware version. In response to this work and discussion within the CL31/TOPROF user community (TOPROF, European COST Action aiming to harmonise ground-based remote sensing networks across Europe), Vaisala released new firmware (versions 1.72 and 2.03) for the CL31 sensors. These firmware versions are tested against previous versions, showing that several artificial features introduced by the data processing have been removed. Hence, it is recommended to use this recent firmware for analysing attenuated backscatter profiles. To allow for consistent processing of historic data, correction procedures have been developed that account for artefacts detected in data collected with older firmware. Furthermore, a procedure is proposed to determine and account for the instrument-related background signal from electronic and optical components. This is necessary for using attenuated backscatter observations from any CL31 ceilometer. Recommendations are made for the processing of attenuated backscatter observed with Vaisala CL31 sensors, including the estimation of noise which is not provided in the standard CL31 output. After taking these aspects into account, attenuated backscatter profiles from Vaisala CL31 ceilometers are considered capable of providing valuable information for a range of applications including atmospheric boundary layer studies, detection of elevated aerosol layers, and model verification.

Abstract. Partial cutting, which removes some individual trees from a forest, is one of the major and widespread forest management practices that can significantly alter both forest structure and carbon (C) storage. Using 746 observations from 82 publications, we synthesized the impacts of partial cutting on three variables associated with forest structure (i.e. mean annual growth of diameter at breast height (DBH), basal area (BA), and volume) and four variables related to various C stock components (i.e. aboveground biomass C (AGBC), understory C, forest floor C, and mineral soil C). Results shows that the growth of DBH elevated by 112% after partial cutting, compared to the uncut control, while stand BA and volume reduced immediately by 34% and 29%, respectively. On average, partial cutting reduced AGBC by 43%, increased understory C storage by 392%, but did not show significant effects on C storages on forest floor and in mineral soil. All the effects on DBH growth, stand BA, volume, and AGBC intensified linearly with cutting intensity (CI) and decreased linearly with the number of recovery years (RY). In addition to the strong impacts of CI and RY, other factors such as climate zone and forest type also affected forest responses to partial cutting. The data assembled in this synthesis were not sufficient to determine how long it would take for a complete recovery after cutting because long-term experiments were rare. Future efforts should be tailored to increase the duration of the experiments and balance geographic locations of field studies.

&lt;p&gt;Plant litter chemistry is altered during decomposition but it remains unknown if these alterations, and thus the composition of residual litter, will change in response to climate. Selective microbial mineralization of litter components and the accumulation of microbial necromass can drive litter compositional change, but the extent to which these mechanisms respond to climate remains poorly understood. We addressed this knowledge gap by studying needle litter decomposition along a boreal forest climate transect. Specifically, we investigated how the composition and/or metabolism of the decomposer community varies with climate, and if that variation is associated with distinct modifications of litter chemistry during decomposition. We analyzed the composition of microbial phospholipid fatty acids (PLFAs) in the litter layer and measured natural abundance &amp;#948;&lt;sup&gt;13&lt;/sup&gt;C&lt;sub&gt;PLFA&lt;/sub&gt; values as an integrated measure of microbial metabolisms. Changes in litter chemistry and &amp;#948;&lt;sup&gt;13&lt;/sup&gt;C values were measured in litterbag experiments conducted at each transect site. A warmer climate was associated with higher litter nitrogen concentrations as well as altered microbial community structure (lower fungi:bacteria ratios) and microbial metabolism (higher &amp;#948;&lt;sup&gt;13&lt;/sup&gt;C&lt;sub&gt;PLFA&lt;/sub&gt;). Litter in warmer transect regions accumulated less aliphatic&amp;#8208;C (lipids, waxes) and retained more O&amp;#8208;alkyl&amp;#8208;C (carbohydrates), consistent with enhanced &lt;sup&gt;13&lt;/sup&gt;C&amp;#8208;enrichment in residual litter, than in colder regions. These results suggest that chemical changes during litter decomposition will change with climate, driven primarily by indirect climate effects (e.g., greater nitrogen availability and decreased fungi:bacteria ratios) rather than direct temperature effects. A positive correlation between microbial biomass &amp;#948;&lt;sup&gt;13&lt;/sup&gt;C values and &lt;sup&gt;13&lt;/sup&gt;C&amp;#8208;enrichment during decomposition suggests that change in litter chemistry is driven more by distinct microbial necromass inputs than differences in the selective removal of litter components. Our study highlights the role that microbial inputs during early litter decomposition can play in shaping surface litter contribution to soil organic matter as it responds to climate warming effects such as greater nitrogen availability.&lt;/p&gt;

Abstract. The LPJ-GUESS dynamic vegetation model uniquely combines an individual- and patch-based representation of vegetation dynamics with ecosystem biogeochemical cycling from regional to global scales. We present an updated version that includes plant and soil N dynamics, analysing the implications of accounting for C\uffe2\uff80\uff93N interactions on predictions and performance of the model. Stand structural dynamics and allometric scaling of tree growth suggested by global databases of forest stand structure and development were well reproduced by the model in comparison to an earlier multi-model study. Accounting for N cycle dynamics improved the goodness of fit for broadleaved forests. N limitation associated with low N-mineralisation rates reduces productivity of cold-climate and dry-climate ecosystems relative to mesic temperate and tropical ecosystems. In a model experiment emulating free-air CO2 enrichment (FACE) treatment for forests globally, N limitation associated with low N-mineralisation rates of colder soils reduces CO2 enhancement of net primary production (NPP) for boreal forests, while some temperate and tropical forests exhibit increased NPP enhancement. Under a business-as-usual future climate and emissions scenario, ecosystem C storage globally was projected to increase by ca. 10%; additional N requirements to match this increasing ecosystem C were within the high N supply limit estimated on stoichiometric grounds in an earlier study. Our results highlight the importance of accounting for C\uffe2\uff80\uff93N interactions in studies of global terrestrial N cycling, and as a basis for understanding mechanisms on local scales and in different regional contexts.

Abstract. Fluvial discharge and coastal erosion of the permafrost-dominated East Siberian Arctic delivers large quantities of terrigenous organic carbon (Terr-OC) to marine waters. The composition and fate of the remobilized Terr-OC needs to be better constrained as it impacts the potential for a climate\uffe2\uff80\uff93carbon feedback. In the present study, the bulk isotope (\uffce\uffb413C and \uffce\uff9414C) and macromolecular (lignin-derived phenols) composition of the cross-shelf exported organic carbon (OC) in different marine pools is evaluated. For this purpose, as part of the SWERUS-C3 expedition (July\uffe2\uff80\uff93September 2014), sediment organic carbon (SOC) as well as water column (from surface and near-bottom seawater) dissolved organic carbon (DOC) and particulate organic carbon (POC) samples were collected along the outer shelves of the Kara Sea, Laptev Sea and East Siberian Sea. The results show that the Lena River and the DOC may have a preferential role in the transport of Terr-OC to the outer shelf. DOC concentrations (740\uffe2\uff80\uff933600\uffe2\uff80\uffaf\uffc2\uffb5g\uffe2\uff80\uffafL\uffe2\uff88\uff921) were 1 order of magnitude higher than POC (20\uffe2\uff80\uff93360\uffe2\uff80\uffaf\uffc2\uffb5g\uffe2\uff80\uffafL\uffe2\uff88\uff921), with higher concentrations towards the Lena River plume. The \uffce\uffb413C signatures in the three carbon pools varied from \uffe2\uff88\uff9223.9\uffe2\uff80\uffaf\uffc2\uffb1\uffe2\uff80\uffaf1.9\uffe2\uff80\uffaf\uffe2\uff80\uffb0 in the SOC, \uffe2\uff88\uff9226.1\uffe2\uff80\uffaf\uffc2\uffb1\uffe2\uff80\uffaf1.2\uffe2\uff80\uffaf\uffe2\uff80\uffb0 in the DOC and \uffe2\uff88\uff9227.1\uffe2\uff80\uffaf\uffc2\uffb1\uffe2\uff80\uffaf1.9\uffe2\uff80\uffaf\uffe2\uff80\uffb0 in the POC. The \uffce\uff9414C values ranged between \uffe2\uff88\uff92395\uffe2\uff80\uffaf\uffc2\uffb1\uffe2\uff80\uffaf83 (SOC), \uffe2\uff88\uff92226\uffe2\uff80\uffaf\uffc2\uffb1\uffe2\uff80\uffaf92 (DOC) and \uffe2\uff88\uff92113\uffe2\uff80\uffaf\uffc2\uffb1\uffe2\uff80\uffaf122\uffe2\uff80\uffaf\uffe2\uff80\uffb0 (POC). These stable and radiocarbon isotopes were also different between the Laptev Sea and the East Siberian Sea. Both DOC and POC showed a depleted and younger trend off the Lena River plume. Further, the Pacific inflow and the sea-ice coverage, which works as a barrier preventing the input of \uffe2\uff80\uff9cyoung\uffe2\uff80\uff9d DOC and POC, seem to have a strong influence in these carbon pools, presenting older and more enriched \uffce\uffb413C signatures under the sea-ice extent. Lignin phenols exhibited higher OC-normalized concentrations in the SOC (0.10\uffe2\uff80\uff932.34\uffe2\uff80\uffafmg\uffe2\uff80\uffafg\uffe2\uff88\uff921\uffe2\uff80\uffafOC) and DOC (0.08\uffe2\uff80\uff932.40\uffe2\uff80\uffafmg\uffe2\uff80\uffafg\uffe2\uff88\uff921\uffe2\uff80\uffafOC) than in the POC (0.03\uffe2\uff80\uff931.14\uffe2\uff80\uffafmg\uffe2\uff80\uffafg\uffe2\uff88\uff921\uffe2\uff80\uffafOC). The good relationship between lignin and \uffce\uff9414C signatures in the DOC suggests that a significant fraction of the outer-shelf DOC comes from \uffe2\uff80\uff9cyoung\uffe2\uff80\uff9d Terr-OC. By contrast, the slightly negative correlation between lignin phenols and \uffce\uff9414C signatures in POC, with higher lignin concentrations in older POC from near-bottom waters, may reflect the off-shelf transport of OC from remobilized permafrost in the nepheloid layer. Syringyl\uffe2\uff80\uffaf\uffe2\uff88\uff95\uffe2\uff80\uffafvanillyl and cinnamyl\uffe2\uff80\uffaf\uffe2\uff88\uff95\uffe2\uff80\uffafvannillyl phenol ratios presented distinct clustering between DOC, POC and SOC, implying that those pools may be carrying different Terr-OC of partially different origin. Moreover, 3,5-dihydroxybenzoic acid to vanillyl phenol ratios and p-coumaric acid to ferulic acid ratios, used as a diagenetic indicators, enhanced in POC and SOC, suggesting more degradation within these pools. Overall, the key contrast between enhanced lignin yields both in the youngest DOC and the oldest POC samples reflects a significant decoupling of terrestrial OC sources and pathways.

Abstract. Riverine Fe input is the primary Fe source to the ocean. This study is focused on the distribution of Fe along the Lena River freshwater plume in the Laptev Sea using samples from a 600\u2009km long transect in front of the Lena River mouth. Separation of the particulate (>\u20090.22\u2009\u00b5m), colloidal (0.22\u2009\u00b5m\u20131\u2009kDa), and truly dissolved (\u200999\u2009% of particulate Fe and about 90\u2009% of the colloidal Fe was observed across the shelf, while the truly dissolved phase was almost constant across the Laptev Sea. Thus, the truly dissolved Fe could be an important source of bioavailable Fe for plankton in the central Arctic Ocean, together with the colloidal Fe. Fe-isotope analysis showed that the particulate phase and the sediment below the Lena River freshwater plume had negative \u03b456Fe values (relative to IRMM-14). The colloidal Fe phase showed negative \u03b456Fe values close to the river mouth (about \u22120.20\u2009\u2030) and positive \u03b456Fe values in the outermost stations (about +0.10\u2009\u2030). We suggest that the shelf zone acts as a sink for Fe particles and colloids with negative \u03b456Fe values, representing chemically reactive ferrihydrites. While the positive \u03b456Fe values of the colloidal phase within the outer Lena River freshwater plume, might represent Fe-oxyhydroxides, which remain in the water column, and will be the predominant \u03b456Fe composition in the Arctic Ocean.

Abstract. Improving the skill of Earth system models (ESMs) in representing climate\uffe2\uff80\uff93vegetation interactions is crucial to enhance our predictions of future climate and ecosystem functioning. Therefore, ESMs need to correctly simulate the impact of climate on vegetation, but likewise feedbacks of vegetation on climate must be adequately represented. However, model predictions at large spatial scales remain subjected to large uncertainties, mostly due to the lack of observational patterns to benchmark them. Here, the bidirectional nature of climate\uffe2\uff80\uff93vegetation interactions is explored across multiple temporal scales by adopting a spectral Granger causality framework that allows identification of potentially co-dependent variables. Results based on global and multi-decadal records of remotely sensed leaf area index (LAI) and observed atmospheric data show that the climate control on vegetation variability increases with longer temporal scales, being higher at inter-annual than multi-month scales. Globally, precipitation is the most dominant driver of vegetation at monthly scales, particularly in (semi-)arid regions. The seasonal LAI variability in energy-driven latitudes is mainly controlled by radiation, while air temperature controls vegetation growth and decay in high northern latitudes at inter-annual scales. These observational results are used as a benchmark to evaluate four ESM simulations from the Coupled Model Intercomparison Project Phase\uffc2\uffa05 (CMIP5). Findings indicate a tendency of ESMs to over-represent the climate control on LAI dynamics and a particular overestimation of the dominance of precipitation in arid and semi-arid regions at inter-annual scales. Analogously, CMIP5 models overestimate the control of air temperature on seasonal vegetation variability, especially in forested regions. Overall, climate impacts on LAI are found to be stronger than the feedbacks of LAI on climate in both observations and models; in other words, local climate variability leaves a larger imprint on temporal LAI dynamics than vice versa. Note however that while vegetation reacts directly to its local climate conditions, the spatially collocated character of the analysis does not allow for the identification of remote feedbacks, which might result in an underestimation of the biophysical effects of vegetation on climate. Nonetheless, the widespread effect of LAI variability on radiation, as observed over the northern latitudes due to albedo changes, is overestimated by the CMIP5 models. Overall, our experiments emphasise the potential of benchmarking the representation of particular interactions in online ESMs using causal statistics in combination with observational data, as opposed to the more conventional evaluation of the magnitude and dynamics of individual variables.

Abstract. High biogenic silica (BSi) concentrations occur sporadically in lake sediments throughout the world; however, the processes leading to high BSi concentrations vary. We explored the factors responsible for the high BSi concentration in sediments of a small, high-latitude subarctic lake (Lake 850). The Si budget of this lake had not been fully characterized before to establish the drivers of BSi accumulation in this environment. To do this, we combined measurements of variations in stream discharge, dissolved silica (DSi) concentrations, and stable Si isotopes in both lake and stream water with measurements of BSi content in lake sediments. Water, radon, and Si mass balances revealed the importance of groundwater discharge as a main source of DSi to the lake, with groundwater-derived DSi inputs 3 times higher than those from ephemeral stream inlets. After including all external DSi sources (i.e., inlets and groundwater discharge) and estimating the total BSi accumulation in the sediment, we show that diatom production consumes up to 79\u2009% of total DSi input. Additionally, low sediment accumulation rates were observed based on the dated gravity core. Our findings thus demonstrate that groundwater discharge and low mass accumulation rate can account for the high BSi accumulation during the last 150\u2009cal\u2009yr\u2009BP. Globally, lakes have been estimated to retain one-fifth of the annual DSi terrestrial weathering flux that would otherwise be delivered to the ocean. Well-constrained lake mass balances, such as presented here, bring clarity to those estimates of the terrestrial Si cycle sinks.

Abstract. In the age of big data, soil data are more available and richer than ever, but \u2013 outside of a few large soil survey resources \u2013 they remain largely unusable for informing soil management and understanding Earth system processes beyond the original study. Data science has promised a fully reusable research pipeline where data from past studies are used to contextualize new findings and reanalyzed for new insight. Yet synthesis projects encounter challenges at all steps of the data reuse pipeline, including unavailable data, labor-intensive transcription of datasets, incomplete metadata, and a lack of communication between collaborators. Here, using insights from a diversity of soil, data, and climate scientists, we summarize current practices in soil data synthesis across all stages of database creation: availability, input, harmonization, curation, and publication. We then suggest new soil-focused semantic tools to improve existing data pipelines, such as ontologies, vocabulary lists, and community practices. Our goal is to provide the soil data community with an overview of current practices in soil data and where we need to go to fully leverage big data to solve soil problems in the next century.

Abstract. Elevated atmospheric CO2 concentration is expected to increase leaf CO2 assimilation rates, thus promoting plant growth and increasing leaf area. It also decreases stomatal conductance, allowing water savings that have been hypothesized to drive large-scale greening, in particular in arid and semiarid climates. However, the increase in leaf area could reduce the ameliorating effect of elevated CO2 concentration on soil water depletion. The net effect of elevated CO2 on leaf- and canopy-level gas exchange thus remains unclear. To address this question, a heuristic model based on the Partitioning of Equilibrium Transpiration and Assimilation (PETA) hypothesis and a model based on stomatal optimization theory are used and their outcomes compared. Predicted relative changes in leaf- and canopy-level gas exchange rates are used as a metric of responses to changes in atmospheric CO2 concentration. Both models predict reductions of leaf-level transpiration rate due to decreased stomatal conductance under elevated CO2, but negligible (PETA) or no (optimization) changes in canopy-level transpiration due to the compensatory effect of increased leaf area. Leaf- and canopy-level CO2 assimilation are predicted to increase, with an amplification of the CO2 fertilization effect at the canopy-level due to the enhanced leaf area. The expected increase in vapor pressure deficit (VPD) under warmer conditions is predicted to decrease the sensitivity of gas exchange to atmospheric CO2 concentration in both models except at growth temperatures lower than the photosynthetic thermal optimum. The consistent predictions by different models that canopy-level transpiration varies little under elevated CO2 due to combined stomatal conductance reduction and leaf area increase highlights the coordination of physiological and morphological characteristics in vegetation to maximize resource use (here water) under altered atmospheric conditions.

Abstract. Riverine Fe input is the primary Fe source to the ocean. This study is focused on the distribution of Fe along the Lena River freshwater plume in the Laptev Sea using samples from a 600\u2009km long transect in front of the Lena River mouth. Separation of the particulate (>\u20090.22\u2009\u00b5m), colloidal (0.22\u2009\u00b5m\u20131\u2009kDa), and truly dissolved (\u200999\u2009% of particulate Fe and about 90\u2009% of the colloidal Fe was observed across the shelf, while the truly dissolved phase was almost constant across the Laptev Sea. Thus, the truly dissolved Fe could be an important source of bioavailable Fe for plankton in the central Arctic Ocean, together with the colloidal Fe. Fe-isotope analysis showed that the particulate phase and the sediment below the Lena River freshwater plume had negative \u03b456Fe values (relative to IRMM-14). The colloidal Fe phase showed negative \u03b456Fe values close to the river mouth (about \u22120.20\u2009\u2030) and positive \u03b456Fe values in the outermost stations (about +0.10\u2009\u2030). We suggest that the shelf zone acts as a sink for Fe particles and colloids with negative \u03b456Fe values, representing chemically reactive ferrihydrites. While the positive \u03b456Fe values of the colloidal phase within the outer Lena River freshwater plume, might represent Fe-oxyhydroxides, which remain in the water column, and will be the predominant \u03b456Fe composition in the Arctic Ocean.

Abstract. Researchers have known for decades that silicon plays a major role in biogeochemical and plant-soil processes in terrestrial systems. Meanwhile, plant biologists continue to uncover a growing list of benefits derived from silicon to combat abiotic and biotic stresses, such as defense against herbivory. Yet despite growing recognition of herbivores as important ecosystem engineers, many major gaps remain in our understanding of how silicon and herbivory interact to shape biogeochemical processes, particularly in natural systems. We review and synthesize 119 available studies directly investigating silicon and herbivory to summarize key trends and highlight research gaps and opportunities. Categorizing studies by multiple ecosystem, plant, and herbivore characteristics, we find substantial evidence for a wide variety of important interactions between plant silicon and herbivory, but highlight the need for more research particularly in non-graminoid dominated vegetation outside of the temperate biome as well as on the potential effects of herbivory on silicon cycling. Continuing to overlook silicon-herbivory dynamics in natural ecosystems limits our understanding of potentially critical animal-plant-soil feedbacks necessary to inform land management decisions and to refine global models of environmental change.

Abstract. Peatlands are important natural sources of atmospheric methane (CH4) emissions. The emissions are strongly influenced by the diffusion of oxygen into the soil and of CH4 from the soil to the atmosphere. This diffusion, in turn, is controlled by the structure of macropore networks. The characterization of peat pore structure and connectivity through complex network theory approaches can give insight into how the relationship between the microscale pore space properties and CH4 emissions on a macroscopic scale is shaped. The formation of anaerobic pockets, which are local hotspots of CH4 production in unsaturated peat, can also be conceptualized through a pore network approach. In this study, we extracted interconnecting macropore networks from three-dimensional X-ray micro-computed tomography (\u00b5CT) images of peat samples and evaluated local and global connectivity metrics for the networks. We also simulated the water retention characteristics of the peat samples using a pore network modeling approach and compared the simulation results with measured water retention characteristics. The results showed large differences in peat macropore structure and pore network connectivity between vertical soil layers. The macropore space was more connected and the flow paths through the peat matrix were less tortuous near the soil surface than at deeper depths. In addition, macroporosity, structural anisotropy, and average pore throat diameter decreased with depth. Narrower and more winding air-filled diffusion channels may reduce the rate of CH4 transport as the distance from the peat layer to the soil\u2013air interface increases. Hysteresis was found to affect the evolution of the volume of connected air-filled pore space in unsaturated peat. Thus, the formation of anaerobic pockets may occur in a smaller soil volume and methanogenesis may be slower when the peat is wetting compared to drying conditions. This hysteretic behavior should be taken into account in biogeochemical models to explain the hotspots and episodic spikes of CH4 emissions. The network analysis also suggests that both local and global network connectivity metrics, such as the network average clustering coefficient and closeness centrality, might serve as proxies for assessing the efficiency of CH4 diffusion in air-filled pore networks. However, the applicability of the network metrics was restricted to the high-porosity near-surface layer. The spatial extent and global continuity of the pore network and the spatial distribution of the pores may be reflected in different network metrics in contrasting ways.

Abstract. Elevated atmospheric CO2 concentration is expected to increase leaf CO2 assimilation rates, thus promoting plant growth and increasing leaf area. It also decreases stomatal conductance, allowing water savings that have been hypothesized to drive large-scale greening, in particular in arid and semiarid climates. However, the increase in leaf area could reduce the ameliorating effect of elevated CO2 concentration on soil water depletion. The net effect of elevated CO2 on leaf- and canopy-level gas exchange thus remains unclear. To address this question, a heuristic model based on the Partitioning of Equilibrium Transpiration and Assimilation (PETA) hypothesis and a model based on stomatal optimization theory are used and their outcomes compared. Predicted relative changes in leaf- and canopy-level gas exchange rates are used as a metric of responses to changes in atmospheric CO2 concentration. Both models predict reductions of leaf-level transpiration rate due to decreased stomatal conductance under elevated CO2, but negligible (PETA) or no (optimization) changes in canopy-level transpiration due to the compensatory effect of increased leaf area. Leaf- and canopy-level CO2 assimilation are predicted to increase, with an amplification of the CO2 fertilization effect at the canopy-level due to the enhanced leaf area. The expected increase in vapor pressure deficit (VPD) under warmer conditions is predicted to decrease the sensitivity of gas exchange to atmospheric CO2 concentration in both models except at growth temperatures lower than the photosynthetic thermal optimum. The consistent predictions by different models that canopy-level transpiration varies little under elevated CO2 due to combined stomatal conductance reduction and leaf area increase highlights the coordination of physiological and morphological characteristics in vegetation to maximize resource use (here water) under altered atmospheric conditions.

Abstract. Framed within the Copernicus Climate Change Service (C3S) of the European Commission, the European Centre for Medium-Range Weather Forecasts (ECMWF) is producing an enhanced global dataset for the land component of the fifth generation of European ReAnalysis (ERA5), hereafter referred to as ERA5-Land. Once completed, the period covered will span from 1950 to the present, with continuous updates to support land monitoring applications. ERA5-Land describes the evolution of the water and energy cycles over land in a consistent manner over the production period, which, among others, could be used to analyse trends and anomalies. This is achieved through global high-resolution numerical integrations of the ECMWF land surface model driven by the downscaled meteorological forcing from the ERA5 climate reanalysis, including an elevation correction for the thermodynamic near-surface state. ERA5-Land shares with ERA5 most of the parameterizations that guarantees the use of the state-of-the-art land surface modelling applied to numerical weather prediction (NWP) models. A main advantage of ERA5-Land compared to ERA5 and the older ERA-Interim is the horizontal resolution, which is enhanced globally to 9\uffe2\uff80\uff89km compared to 31\uffe2\uff80\uff89km (ERA5) or 80\uffe2\uff80\uff89km (ERA-Interim), whereas the temporal resolution is hourly as in ERA5. Evaluation against independent in situ observations and global model or satellite-based reference datasets shows the added value of ERA5-Land in the description of the hydrological cycle, in particular with enhanced soil moisture and lake description, and an overall better agreement of river discharge estimations with available observations. However, ERA5-Land snow depth fields present a mixed performance when compared to those of ERA5, depending on geographical location and altitude. The description of the energy cycle shows comparable results with ERA5. Nevertheless, ERA5-Land reduces the global averaged root mean square error of the skin temperature, taking as reference MODIS data, mainly due to the contribution of coastal points where spatial resolution is important. Since January\uffc2\uffa02020, the ERA5-Land period available has extended from January\uffc2\uffa01981 to the near present, with a 2- to 3-month delay with respect to real time. The segment prior to 1981 is in production, aiming for a release of the whole dataset in summer/autumn\uffc2\uffa02021. The high spatial and temporal resolution of ERA5-Land, its extended period, and the consistency of the fields produced makes it a valuable dataset to support hydrological studies, to initialize NWP and climate models, and to support diverse applications dealing with water resource, land, and environmental management. The full ERA5-Land hourly (Mu\uffc3\uffb1oz-Sabater,\uffc2\uffa02019a) and monthly (Mu\uffc3\uffb1oz-Sabater,\uffc2\uffa02019b) averaged datasets presented in this paper are available through the C3S Climate Data Store at https://doi.org/10.24381/cds.e2161bac and https://doi.org/10.24381/cds.68d2bb30, respectively.
