To improve the predictive capability of ecosystem biogeochemical models (EBMs), we discuss the feasibility of formulating biogeochemical processes using physical rules that have underpinned the many successes in computational physics and chemistry. We argue that the currently popular empirically based approaches, such as multiplicative empirical response functions and the law of the minimum, will not lead to EBM formulations that can be continuously refined to incorporate improved mechanistic understanding and empirical observations of biogeochemical processes. Instead, we propose that EBM parameterizations, as a lossy data compression problem, can be better formulated using established physical rules widely used in computational physics and chemistry, and different biogeochemical processes can be more robustly integrated within a reactive\uffe2\uff80\uff90transport framework. Through several examples, we demonstrate how mathematical representations derived from physical rules can improve understanding of relevant biogeochemical processes and enable more effective communication between modelers, observationalists, and experimentalists regarding essential questions, such as what measurements are needed to meaningfully inform models and how can models generate new process\uffe2\uff80\uff90level hypotheses to test in empirical studies. Finally, while empirical models with more parameters are often less robust, physical rules\uffe2\uff80\uff90based models can be more robust and show lower predictive equifinality, stemming from their enhanced consistency in representations of processes, interactions and spatial scaling.Nature Communications, 2022. We performed an observational synthesis of soil fractionation data constituting 1,144 globally-distributed soil profiles from 78 studies that reported fractionation and bulk measurements of organic carbon across depths. This dataset includes measurements of mineral-associated, particulate, and bulk soil organic carbon, as well as ancillary data on edaphic, climate, and vegetation characteristics. We also performed a separate observational synthesis of soil carbon accrual from manipulation and chronosequence studies, which included changes in carbon stocks or concentrations, bulk density, experimental duration, and edaphic properties. This latter synthesis included 103 observations from 34 studies that spanned crop, pasture, grassland, and forest ecosystems across climates and soil types.

Warming air and sea temperatures, longer open-water seasons and sea-level rise collectively promote the erosion of permafrost coasts in the Arctic, which profoundly impacts organic matter pathways. Although estimates on organic carbon (OC) fluxes from erosion exist for some parts of the Arctic, little is known about how much OC is transformed into greenhouse gases (GHGs). In this study we investigated two different coastal erosion scenarios on Qikiqtaruk \uffe2\uff80\uff93 Herschel Island (Canada) and estimate the potential for GHG formation. We distinguished between adelayedrelease represented bymud debrisdraining a coastal thermoerosional feature and adirectrelease represented bycliff debrisat a low collapsing bluff. Carbon dioxide (CO2) production was measured during incubations at 4\uffc2\uffb0C under aerobic conditions for two months and were modeled for four months and a full year. Our incubation results show thatmud debrisandcliff debrislost a considerable amount of OC as CO2(2.5 \uffc2\uffb1 0.2 and 1.6 \uffc2\uffb1 0.3% of OC, respectively). Although relative OC losses were highest in mineralmud debris, higher initial OC content and fresh organic matter incliff debrisresulted in a \uffe2\uff88\uffbcthree times higher cumulative CO2release (4.0 \uffc2\uffb1 0.9 compared to 1.4 \uffc2\uffb1 0.1 mg CO2gdw\uffe2\uff80\uff931), which was further increased by the addition of seawater. After four months, modeled OC losses were 4.9 \uffc2\uffb1 0.1 and 3.2 \uffc2\uffb1 0.3% in set-ups without seawater and 14.3 \uffc2\uffb1 0.1 and 7.3 \uffc2\uffb1 0.8% in set-ups with seawater. The results indicate that adelayedrelease may support substantial cycling of OC at relatively low CO2production rates during long transit timesonshoreduring the Arctic warm season. By contrast,directerosion may result in a single CO2pulse and less substantial OC cyclingonshoreas transfer times are short. Once eroded sediments are deposited in thenearshore, highest OC losses can be expected. We conclude that the release of CO2from eroding permafrost coasts varies considerably between erosion types and residence timeonshore. We emphasize the importance of a more comprehensive understanding of OC degradation during the coastal erosion process to improve thawed carbon trajectories and models.Abstract. Nitrous oxide (N2O) is an important greenhouse gas. N2O emissions from soils vary with fertilization and cropping practices. The response of N2O emission to fertilization of agricultural soils plays an important role in global N2O emission. The objective of this study was to assess the seasonal pattern of N2O fluxes and the annual N2O emissions from a rain-fed winter wheat (Triticum aestivum L.) field in the Loess Plateau of China. A static flux chamber method was used to measure soil N2O fluxes from 2006 to 2008. The study included 5 treatments with 3 replications in a randomized complete block design. Prior to initiating N2O measurements the treatments had received the same fertilization for 22 years. The fertilizer treatments were unfertilized control (CK), manure (M), nitrogen (N), nitrogen + phosphorus (NP), and nitrogen + phosphorus + manure (NPM). Soil N2O fluxes in the highland winter wheat field were highly variable temporally and thus were fertilization dependent. The highest fluxes occurred in the warmer and wetter seasons. Relative to CK, M slightly increased N2O flux while N, NP and NPM treatments significantly increased N2O fluxes. The fertilizer induced increase in N2O flux occurred mainly in the first 30 days after fertilization. The increases were smaller in the relatively warm and dry year than in the cold and wet year. Combining phosphorous and/or manure with mineral N fertilizer partly offset the nitrogen fertilizer induced increase in N2O flux. N2O fluxes at the seedling stage were mainly controlled by nitrogen fertilization, while fluxes at other plant growth stages were influenced by plant and environmental conditions. The cumulative N2O emissions were always higher in the fertilized treatments than in the non-fertilized treatment (CK). Mineral and manure nitrogen fertilizer enhanced N2O emissions in wetter years compared to dryer years. Phosphorous fertilizer offset 0.78 and 1.98 kg N2O ha\uffe2\uff88\uff921 increases, while manure + phosphorous offset 0.67 and 1.64 kg N2O ha\uffe2\uff88\uff921 increases by N fertilizer for the two observation years. Our results suggested that the contribution of single N fertilizer on N2O emission was larger than that of NP and NPM and that manure and phosphorous had important roles in offsetting mineral N fertilizer induced N2O emissions. Relative to agricultural production and N2O emission, manure fertilization (M) should be recommended while single N fertilization (N) should be avoided for the highland winter wheat due to the higher biomass and grain yield and less N2O flux and annual emission in M than in N.

Abstract. Earlier studies have demonstrated that soil texture and geochemistry strongly affect soil organic carbon (SOC) content. However, those findings primarily rely on data from temperate regions with soil mineralogy, weathering status and climatic conditions that generally differ from tropical and sub-tropical regions. We investigated soil properties and climate variables influencing SOC concentrations across sub-Saharan Africa. A total of 1,601 samples were analyzed, collected from two depths (0\uffe2\uff80\uff9320\uffe2\uff80\uff89cm and 20\uffe2\uff80\uff9350\uffe2\uff80\uff89cm) at 45 sentinel sites from 17 countries as part of the Africa Soil Information Service (AfSIS) project. The dataset spans climatic conditions from arid to humid and includes soils with a wide range of pHH20 values, weathering status, soil texture, exchangeable cations, extractable metals and a variety of important land cover types. The most important SOC predictors were identified by linear mixed effects models, regression trees and random forest models. Our results indicate that SOC is primarily controlled by aridity index (PET/MAP), exchangeable calcium (Caex) and oxalate-extractable aluminum (Alox); this was found across both depth intervals. Oxalate-extractable iron (Feox) emerged as the most important predictor for both depth intervals in the regression tree and random forest analyses. However, its influence on SOC concentrations was strong only below Feox concentrations of 0.25\uffe2\uff80\uff89wt\uffe2\uff80\uff89%. This suggests that Feox can act as a pedogenic threshold \uffe2\uff80\uff93 even on a continental scale. Across model-ling approaches, clay and fine silt content (

By providing an abundance of sites for the sorption and incorporation of major and trace elements, Fe minerals can govern the fate and behaviour of numerous pollutants and nutrients in soils. Furthermore, the reactivity of Fe in redox-dynamic soils produces a web of Fe mineral transformation processes with broad consequences for element cycling. The importance of Fe cycling is no exception in acid sulfate soils, although the high sulfur and low pH conditions produce unique Fe mineral transformation processes and compositions. In acid sulfate soils, jarosite, an Fe-K hydroxysulfate mineral, and ferrihydrite, a common short-range-ordered Fe oxyhydroxide mineral, play a central role in the pedological development of active and post-active acid sulfate soils. Soil pH and the dynamics of metals, such as aluminium, are key to understanding the toxicity of acid sulfate soils and can be directly influenced by jarosite and ferrihydrite transformation processes. Although the transformation of Fe minerals is a key component of biogeochemical processes in redox-active soils, the variables that control the rates and pathways of Fe mineral transformations in soil remain uncertain. The uncertainty arises from the difficulty of tracing molecular processes within a matrix of diverse soil components. Iron minerals are regularly characterised in soils, but the processes that explain the Fe mineral composition of soils cannot be easily resolved. An alternative approach is to perform simplified experiments, such as mixed mineral suspension experiments, under controlled laboratory conditions, to test the effect of individual variables. These systems often use synthetic minerals, although relatively pure jarosite may also be isolated from soils and tested in mixed suspension experiments. While useful to derive mechanistic understanding, the measured outcomes of mixed suspension experiments may not represent the rates and products of transformations that occur in soils. Therefore, the objective of this thesis was to gain new understanding of the stability and transformation of jarosite and ferrihydrite in acid sulfate soils by developing novel experimental techniques to follow the transformation of synthetic jarosite and ferrihydrite directly in soils. The central theme of the thesis is the comparison of jarosite and aluminium-substituted jarosite transformation in experimental media of increasing complexity. The experiments are performed under conditions that are relevant to rice paddy soils because of the importance of rice in global food production, and the unique management of rice paddies whereby regular flooding during the growing season produces distinct redox cycles. In Thailand, large areas of the Chao Phraya River delta are cultivated as rice paddies despite being acid sulfate soils, providing a suitable site to observe the effects of regular redox cycling on the biogeochemistry of Fe minerals in acid sulfate soils. The thesis begins with characterisation of synthetic and natural jarosite mineral composition and reactivity. Spectroscopic techniques (Raman spectroscopy, M\u00f6ssbauer spectroscopy and Energy-dispersive X-ray spectrometry) and X-ray diffraction (XRD) were used to assess the element substitution of mineral samples from two jarosite-alunite synthetic solid solution series. The same characterisation techniques were then applied to a sample of jarosite from an acid sulfate soil in Thailand has a natural Al-for-Fe substitution. The mineral characterisation was followed by a transformation experiment in a mixed-suspension system, similar to experimental designs that have been previously used to study mineral transformation processes. The experiment followed the transformation of the natural jarosite sample from an acid sulfate soil in Thailand and three jarosite samples with variable amounts of Al substitution. The reaction solution mimicked the pH (circumneutral) and Fe(II) content (up to 1:1 ratio of Fe(II) in solution to Fe(III) in solids) of flooded acid sulfate soils. Furthermore, using a 57Fe tracer, the simultaneous transformation processes that explained the distribution of mineral products could be resolved from one another. The transformation experiment revealed the relative reactivity of the minerals in the presence of Fe(II), and created a baseline that could be used to compare traditional mixed-suspension experiments with transformations in complex media such as soil. To advance mineral transformation experiments towards studies in which transformation processes may be followed within a soil matrix, several novel techniques were developed. In a first step, ferrihydrite was incubated for up to twelve weeks in microcosms, each containing 300 g of 5 mM CaCl2 solution and 250 g of one of five paddy soils. The ferrihydrite was buried in the soil within a mesh bag (polyethel terephthalate, 51 \u03bcm pores, 30 mm x 12 mm x 3 mm) that allowed free contact between the synthetic minerals and the pore water, but separated the minerals from direct contact with the soil matrix. The mineral products of the transformation were identified and quantified by Rietveld fitting of XRD patterns. Further, the spatial arrangements of the ferrihydrite and transformation products were measured after two weeks by Raman spectroscopy, which could be used to assess the effects of pore water chemistry and diffusion processes on mineral transformation in the mesh bags. The second step involved measuring jarosite and Al-substituted jarosite transformation in flooded topsoil and subsoils from a rice paddy located on the Bangkok Plain in Central Thailand using an adaptation of the mesh bag method. To test the effect of pore water on the transformation of jarosite in soil, mesh bags were filled with synthetic jarosite and aluminium-jarosite and incubated in topsoils and subsoils, both in laboratory mesocosms and directly in the field. Then, the effect of the soil matrix was tested by completing a parallel experiment using mesh bags containing soil that was pre-enriched with synthetic 57Fe-labelled jarosite and aluminium-substituted jarosite. To facilitate the deployment and collection of small mesh bags in large soil volumes, the mesh bags were inserted into soils using custom-designed 3D-printed sample holders. At three timepoints within twelve weeks, one set of mesh bags were removed from the soil. Transformation products were identified and quantified in the pure jarosite and aluminium-jarosite mesh bags using Rietveld fitting of XRD patterns, while the fate of the 57Fe in enriched soil mesh bags was traced using 57Fe M\u00f6ssbauer spectroscopy. Performing experiments in increasingly complex media provides an insight into the effect of experimental design on the observation of Fe mineral transformations and provides new information regarding the transformation rates and pathways of jarosite and ferrihydrite within full complexity of soil media. Indeed, this thesis demonstrates that the complex chemistry, biological activity, and physical arrangement of components in the soil have strong effects on the rate and products of jarosite and ferrihydrite transformation processes. The transformation of jarosite and Al-substituted jarosite in mixed-suspension experiments presented in this thesis, in agreement with previous mixed-suspension experiments on both jarosite and ferrihydrite, occurred within a matter of hours. By contrast, the rate of ferrihydrite, jarosite and Al-jarosite transformation in soil pore and in direct contact with the soil matrix occurred over the course of several weeks or months. In the ferrihydrite mesh bags, slow ferrihydrite transformation kinetics on the outer rim of the mesh bag, and deep in the core of the mesh bag, indicated that the sorption of chemical components of soil pore water and diffusion limitations of Fe(II) in pore water could be reasons for the slower rates of transformation in soil. In addition, both Al-for-Fe substitution and Fe(II) concentration in solution were important factors that altered the rate of mineral transformation. The different incubation conditions for jarosite and Al-jarosite also altered the products of the transformation. Whereas the hydrolysis of jarosite in the absence of Fe(II) resulted primarily in the formation of ferrihydrite, jarosite transformation in the presence of Fe(II) led to ferrihydrite, goethite and lepidocrocite formation. The Fe oxyhydroxide products were consistent with Fe(II)-catalysed transformation, and Fe(II)-catalysed recrystallisation of jarosite may have occurred concurrently. Aluminium-for-iron substitution hindered the formation of lepidocrocite formation in favour of ferrihydrite and goethite. Similar product phases occurred when jarosite and Al-jarosite were reacted with pore water from acid sulfate soils, indicating that similar transformation pathways may define the mineral products of jarosite transformations when the jarosite occurs as accumulations of pure mineral in soil. However, non- or poorly crystalline phases predominated in the transformation products when jarosite or Al-jarosite were incubated in direct contact with the soil matrix, indicating that the transformation of jarosite under these circumstances was governed by different pathways and processes. The new insights into the transformation of ferrihydrite, jarosite and Al-jarosite in acid sulfate soils demonstrate that phases previously considered meta-stable may participate in the biogeochemistry of soil over period of several months. In the context of rice cultivation, the transformation processes may affect the biogeochemistry of the soils throughout the growing season. The formation of poorly crystalline minerals following the transformation in flooded soils may have positive consequences on the sequestration of other trace and major elements that were associated with the ferrihydrite, jarosite or Al-jarosite prior to the transformation. However, the stabilisation of reduced Fe in the soil matrix may have the opposite effect, promoting the mobility of other ions in solution. The methods used to incubate jarosite and ferrihydrite in soils are easily adaptable to new experimental questions involving the behaviour of Fe-bearing minerals in soil. Therefore, the findings open up a new class of experiments within environmental mineralogy and biogeochemistry, that can help to uncover the processes that occur in the environment and explain the natural variation in the composition of Fe phases in soil.", "keywords": ["jarosite", "iron biogeochemistry", "soil chemistry", "acid sulfate soil", "laboratory study", "ferrihydrite", "soil", "soil incubation", "redox chemistry", "goethite", "iron minerals", "2.

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. The magnitude of carbon (C) loss to the atmosphere via microbial decomposition is a function of the amount of C stored in soils, the quality of the organic matter, and physical, chemical and biological factors that comprise the environment for decomposition. The decomposability of C is commonly assessed by laboratory soil incubation studies that measure greenhouse gases mineralized from soils under controlled conditions. Here, we introduce the Soil Incubation Database (SIDb) version 1.0, a compilation of time series data from incubations, structured into a new, publicly available database of C flux (carbon dioxide, CO2, or methane, CH4). In addition to open access, the SIDb project also provides a platform for the development of tools for reading and analysis of incubation data as well as documentation for future use and development. In addition to introducing SIDb, we provide reporting guidance for database entry and the required variables that incubation studies need at minimum to be included in SIDb. A key application of this synthesis effort is to better characterize soil C processes in Earth system models, which will in turn reduce our uncertainty in predicting the response of soil C decomposition to a changing climate. We demonstrate a framework to fit curves to a number of incubation studies from diverse ecosystems, depths, and organic matter content using a built-in model development module that integrates SIDb with the existing SoilR package to estimate soil C pools from time series data. The database will help bridge the gap between site-level measurements, which are commonly used in incubation studies, and global remote-sensed data or data products derived from models aimed at assessing global-scale rates of decomposition and C turnover. The SIDb, version 1.0, is archived and publicly available at DOI: https://doi.org/10.5281/zenodo.3470459 (Sierra et al., 2019) and the database is managed under a version-controlled system and centrally stored in GitHub (https://github.com/SoilBGC-Datashare/sidb).

Abstract. Earlier studies have demonstrated that soil texture and geochemistry strongly affect soil organic carbon (SOC) content. However, those findings primarily rely on data from temperate regions with soil mineralogy, weathering status and climatic conditions that generally differ from tropical and sub-tropical regions. We investigated soil properties and climate variables influencing SOC concentrations across sub-Saharan Africa. A total of 1,601 samples were analyzed, collected from two depths (0\u201320\u2009cm and 20\u201350\u2009cm) at 45 sentinel sites from 17 countries as part of the Africa Soil Information Service (AfSIS) project. The dataset spans climatic conditions from arid to humid and includes soils with a wide range of pHH20 values, weathering status, soil texture, exchangeable cations, extractable metals and a variety of important land cover types. The most important SOC predictors were identified by linear mixed effects models, regression trees and random forest models. Our results indicate that SOC is primarily controlled by aridity index (PET/MAP), exchangeable calcium (Caex) and oxalate-extractable aluminum (Alox); this was found across both depth intervals. Oxalate-extractable iron (Feox) emerged as the most important predictor for both depth intervals in the regression tree and random forest analyses. However, its influence on SOC concentrations was strong only below Feox concentrations of 0.25\u2009wt\u2009%. This suggests that Feox can act as a pedogenic threshold \u2013 even on a continental scale. Across model-ling approaches, clay and fine silt content (

While this has resulted in large ecological changes aboveground such as altered tree species composition and increased forest density, little is known about the long-term, belowground implications of altered, ecologically novel fire regimes, especially on soil biological processes. To better understand the long-term implications of ecologically novel, high-severity fire, we used a 44-y high-severity fire chronosequence in the Sierra Nevada where forests were historically adapted to frequent, low-severity fire, but were fire suppressed for at least 70 years. High-severity fire in the Sierra Nevada resulted in a long-term (44+ y) decrease (>50%, p < 0.05) in soil extracellular enzyme activities, basal microbial respiration (56-72%, p < 0.05), and organic carbon (>50%, p < 0.05) in the upper 5 cm compared to sites that had not been burned for at least 115 y. However, nitrogen (N) processes were only affected in the most-recent fire site (4 y post-fire). Net nitrification increased by over 600% in the most recent fire site (p < 0.001), but returned to similar levels as the unburned control in the 13-y site. Contrary to previous studies, we did not find a consistent effect of plant cover type on soil biogeochemical processes in mid-successional (10-50 y) forest soils. Rather, the 44-y reduction in soil organic carbon (C) quantity correlated positively with dampened C cycling processes. Our results show the drastic and long-term implication of ecologically novel, high-severity fire on soil biogeochemistry and underscore the need for long-term fire ecological experiments.", "keywords": ["soil organic carbon", "soil biogeochemistry", "microbial biomass", "microbial respiration", "13.

They instead rely on vapour-pressure deficit as a proxy for dryness, despite widespread evidence that soil moisture deficits have a direct impact on vegetation, independent of vapour-pressure deficit.

We develop methods to account for the influence of soil moisture and estimate that soil moisture effects reduce global annual photosynthesis by ~15%, increase interannual variability by more than 100% across 25% of the global vegetated land surface, and amplify the impacts of extreme events on primary production.

Manipulative experiments and observations along environmental gradients, the two most common approaches to evaluate the impacts of climate change on nutrient cycling, are generally assumed to produce similar results, but this assumption has rarely been tested. We did so by conducting a meta-analysis and found that soil nutrients responded differentially to drivers of climate change depending on the approach considered. Soil carbon, nitrogen, and phosphorus concentrations generally decreased with water addition in manipulative experiments but increased with annual precipitation along environmental gradients. Different patterns were also observed between warming experiments and temperature gradients. Our findings provide evidence of inconsistent results and suggest that manipulative experiments may be better predictors of the causal impacts of short-term (months to years) climate change on soil nutrients but environmental gradients may provide better information for long-term correlations (centuries to millennia) between these nutrients and climatic features. Ecosystem models should consequently incorporate both experimental and observational data to properly assess the impacts of climate change on nutrient cycling.

We assessed the evidence for dual-colonization of aspen by ecto- and arbuscular mycorrhizal (AM) fungi at two soil depths across 27 stands across nearly 1500 km spanning boreal and parkland biomes. Given the increase in arbuscular mycorrhizas with temperature and evapotranspiration and the opposite for ectomycorrhizas, we hypothesized that AM fungi would increase, and ectomycorrhizal fungi decrease in abundance with decreasing moisture availability. Second, simultaneous with our regional-scale survey, we examined some ecosystem correlates of putative shifts in the dominance of mycorrhizal type in aspen. We measured leaf traits connected to nutrient economic strategies and decomposition, and pools of carbon and nitrogen in soils of aspen forests. Studies have found that leaves from ectomycorrhizal (EM) tree species decompose slower than those from AM tree species and that mycorrhizal tree type predicts soil C and nutrient dynamics. The mechanism, however, underlying the distinct effects of EM and AM trees on soil organic matter is unclear. Namely, it may not be AM fungi per se, but rather the activity of microbes upon competitive release in the absence of EM fungi that influences soil organic matter dynamics in AM stands. Thus, we hypothesized that variation in EM fungal abundance rather than that of AM fungi may influence soil carbon and nutrient cycling.", "keywords": ["mycorrhizal ecology", "biogeochemistry", "Earth and Environmental Sciences", "15.

Wildfire activity in Arctic and boreal regions is rapidly increasing, with severe consequences for climate and human health. Regional long-term variations in fire frequency and intensity characterize fire regimes. The spatial variability in Arctic\uffe2\uff80\uff93boreal fire regimes and their environmental and anthropogenic drivers, however, remain poorly understood. Here we present a fire tracking system to map the sub-daily evolution of all circumpolar Arctic\uffe2\uff80\uff93boreal fires between 2012 and 2023 using 375\uffe2\uff80\uff89m Visible Infrared Imaging Radiometer Suite active fire detections and the resulting dataset of the ignition time, location, size, duration, spread and intensity of individual fires. We use this dataset to classify the Arctic\uffe2\uff80\uff93boreal biomes into seven distinct \uffe2\uff80\uff98pyroregions\uffe2\uff80\uff99 with unique climatic and geographic environments. We find that these pyroregions exhibit varying responses to environmental drivers, with boreal North America, eastern Siberia and northern tundra regions showing the highest sensitivity to climate and lightning density. In addition, anthropogenic factors play an important role in influencing fire number and size, interacting with other factors. Understanding the spatial variability of fire regimes and its interconnected drivers in the Arctic\uffe2\uff80\uff93boreal domain is important for improving future predictions of fire activity and identifying areas at risk for extreme events.The importance of soil age as an ecosystem driver across biomes remains largely unresolved. By combining a cross-biome global field survey, including data for 32 soil, plant, and microbial properties in 16 soil chronosequences, with a global meta-analysis, we show that soil age is a significant ecosystem driver, but only accounts for a relatively small proportion of the cross-biome variation in multiple ecosystem properties. Parent material, climate, vegetation and topography predict, collectively, 24 times more variation in ecosystem properties than soil age alone. Soil age is an important local-scale ecosystem driver; however, environmental context, rather than soil age, determines the rates and trajectories of ecosystem development in structure and function across biomes. Our work provides insights into the natural history of terrestrial ecosystems. We propose that, regardless of soil age, changes in the environmental context, such as those associated with global climatic and land-use changes, will have important long-term impacts on the structure and function of terrestrial ecosystems across biomes.Warming air and sea temperatures, longer open-water seasons and sea-level rise collectively promote the erosion of permafrost coasts in the Arctic, which profoundly impacts organic matter pathways. Although estimates on organic carbon (OC) fluxes from erosion exist for some parts of the Arctic, little is known about how much OC is transformed into greenhouse gases (GHGs). In this study we investigated two different coastal erosion scenarios on Qikiqtaruk \uffe2\uff80\uff93 Herschel Island (Canada) and estimate the potential for GHG formation. We distinguished between adelayedrelease represented bymud debrisdraining a coastal thermoerosional feature and adirectrelease represented bycliff debrisat a low collapsing bluff. Carbon dioxide (CO2) production was measured during incubations at 4\uffc2\uffb0C under aerobic conditions for two months and were modeled for four months and a full year. Our incubation results show thatmud debrisandcliff debrislost a considerable amount of OC as CO2(2.5 \uffc2\uffb1 0.2 and 1.6 \uffc2\uffb1 0.3% of OC, respectively). Although relative OC losses were highest in mineralmud debris, higher initial OC content and fresh organic matter incliff debrisresulted in a \uffe2\uff88\uffbcthree times higher cumulative CO2release (4.0 \uffc2\uffb1 0.9 compared to 1.4 \uffc2\uffb1 0.1 mg CO2gdw\uffe2\uff80\uff931), which was further increased by the addition of seawater. After four months, modeled OC losses were 4.9 \uffc2\uffb1 0.1 and 3.2 \uffc2\uffb1 0.3% in set-ups without seawater and 14.3 \uffc2\uffb1 0.1 and 7.3 \uffc2\uffb1 0.8% in set-ups with seawater. The results indicate that adelayedrelease may support substantial cycling of OC at relatively low CO2production rates during long transit timesonshoreduring the Arctic warm season. By contrast,directerosion may result in a single CO2pulse and less substantial OC cyclingonshoreas transfer times are short. Once eroded sediments are deposited in thenearshore, highest OC losses can be expected. We conclude that the release of CO2from eroding permafrost coasts varies considerably between erosion types and residence timeonshore. We emphasize the importance of a more comprehensive understanding of OC degradation during the coastal erosion process to improve thawed carbon trajectories and models.Climate change jeopardizes human health, global biodiversity, and sustainability of the biosphere. To make reliable predictions about climate change, scientists use Earth system models (ESMs) that integrate physical, chemical, and biological processes occurring on land, the oceans, and the atmosphere. Although critical for catalyzing coupled biogeochemical processes, microorganisms have traditionally been left out of ESMs. Here, we generate a \uffe2\uff80\uff9ctop 10\uffe2\uff80\uff9d list of priorities, opportunities, and challenges for the explicit integration of microorganisms into ESMs. We discuss the need for coarse-graining microbial information into functionally relevant categories, as well as the capacity for microorganisms to rapidly evolve in response to climate-change drivers. Microbiologists are uniquely positioned to collect novel and valuable information necessary for next-generation ESMs, but this requires data harmonization and transdisciplinary collaboration to effectively guide adaptation strategies and mitigation policy.

Recent hypotheses, based on atmospheric records and models, suggest that permafrost carbon (PF-C) accumulated during the last glaciation may have been an important source for the atmospheric CO2 rise during post-glacial warming. However, direct physical indications for such PF-C release have so far been absent. Here we use the Laptev Sea (Arctic Ocean) as an archive to investigate PF-C destabilization during the last glacial\uffe2\uff80\uff93interglacial period. Our results show evidence for massive supply of PF-C from Siberian soils as a result of severe active layer deepening in response to the warming. Thawing of PF-C must also have brought about an enhanced organic matter respiration and, thus, these findings suggest that PF-C may indeed have been an important source of CO2 across the extensive permafrost domain. The results challenge current paradigms on the post-glacial CO2 rise and, at the same time, serve as a harbinger for possible consequences of the present-day warming of PF-C soils.

Abstract. Biogeochemical cycling in the extensive shelf seas and in the interior basins of the semi-enclosed Arctic Ocean are strongly influenced by land-ocean transport of carbon and other elements. The Arctic carbon cycle system is also inherently connected with the climate, and thus vulnerable to environmental and climate changes. Sediments of the Arctic Ocean are an active and integral part in Arctic biogeochemical cycling, and provide the opportunity to study present and historical input and fate of organic matter (e.g., through permafrost thawing). To compare differences between the Arctic regions and to study Arctic biogeochemical budgets, comprehensive sedimentary records are required. To this end, the Circum-Arctic Sediment CArbon DatabasE (CASCADE) was established to curate data primarily on concentrations of organic carbon (OC) and OC isotopes (\u03b413C, \u039414C), yet also on total N (TN) as well as of terrigenous biomarkers and other sediment geochemical and physical properties drawn both from the published literature and from earlier unpublished records through an extensive international community collaboration. This paper describes the establishment, structure and current status of CASCADE. This first public version includes OC concentrations in surface sediments at 4244 oceanographic stations including 2317 with TN concentrations, 1555 with \u03b413C-OC values, 268 with \u039414C-OC values and 653 records with quantified terrigenous biomarkers (high molecular weight n-alkanes, n-alkanoic acids and lignin phenols) distributed over the shelves and the central basins of the Arctic Ocean. CASCADE also includes data from 326 sediment cores, retrieved by shallow box- or multi-coring and deep gravity/piston coring, as well as sea-bottom drilling. The comprehensive dataset reveals several large-scale features, including clear differences in both OC content and isotope-based diagnostics of OC sources between the shelf sea recipients. This indicates, for instance, the release of strongly pre-aged terrigenous OC to the East Siberian Arctic shelf and younger terrigenous OC to the Kara Sea and thus provides clues about land-ocean transport of material released by thawing permafrost. CASCADE enables synoptic analysis of OC in Arctic Ocean sediments and facilitates a wide array of future empirical and modelling studies of the Arctic carbon cycle. CASCADE is openly and freely available online (https://doi.org/10.17043/cascade; Martens et al., 2020b), is provided in various machine-readable data formats (data tables, GIS shapefile, GIS raster), and also provides ways for contributing data for future CASCADE versions. CASCADE will be continuously updated with newly published and contributed data over the foreseeable future as part of the database management of the Bolin Centre for Climate Research at Stockholm University.

Abstract. The magnitude of carbon (C) loss to the atmosphere via microbial decomposition is a function of the amount of C stored in soils, the quality of the organic matter, and physical, chemical and biological factors that comprise the environment for decomposition. The decomposability of C is commonly assessed by laboratory soil incubation studies that measure greenhouse gases mineralized from soils under controlled conditions. Here, we introduce the Soil Incubation Database (SIDb) version 1.0, a compilation of time series data from incubations, structured into a new, publicly available database of C flux (carbon dioxide, CO2, or methane, CH4). In addition to open access, the SIDb project also provides a platform for the development of tools for reading and analysis of incubation data as well as documentation for future use and development. In addition to introducing SIDb, we provide reporting guidance for database entry and the required variables that incubation studies need at minimum to be included in SIDb. A key application of this synthesis effort is to better characterize soil C processes in Earth system models, which will in turn reduce our uncertainty in predicting the response of soil C decomposition to a changing climate. We demonstrate a framework to fit curves to a number of incubation studies from diverse ecosystems, depths, and organic matter content using a built-in model development module that integrates SIDb with the existing SoilR package to estimate soil C pools from time series data. The database will help bridge the gap between site-level measurements, which are commonly used in incubation studies, and global remote-sensed data or data products derived from models aimed at assessing global-scale rates of decomposition and C turnover. The SIDb, version 1.0, is archived and publicly available at DOI: https://doi.org/10.5281/zenodo.3470459 (Sierra et al., 2019) and the database is managed under a version-controlled system and centrally stored in GitHub (https://github.com/SoilBGC-Datashare/sidb).

Abstract. Understanding how multiphase processes affect the iron-containing aerosol cycle is key to predicting ocean biogeochemistry changes and hence the feedback effects on climate. For this work, the EC-Earth Earth system model in its climate\u2013chemistry configuration is used to simulate the global atmospheric oxalate (OXL), sulfate (SO42-), and iron (Fe) cycles after incorporating a comprehensive representation of the multiphase chemistry in cloud droplets and aerosol water. The model considers a detailed gas-phase chemistry scheme, all major aerosol components, and the partitioning of gases in aerosol and atmospheric water phases. The dissolution of Fe-containing aerosols accounts kinetically for the solution's acidity, oxalic acid, and irradiation. Aerosol acidity is explicitly calculated in the model, both for accumulation and coarse modes, accounting for thermodynamic processes involving inorganic and crustal species from sea salt and dust. Simulations for present-day conditions (2000\u20132014) have been carried out with both EC-Earth and the atmospheric composition component of the model in standalone mode driven by meteorological fields from ECMWF's ERA-Interim reanalysis. The calculated global budgets are presented and the links between the (1) aqueous-phase processes, (2) aerosol dissolution, and (3) atmospheric composition are demonstrated and quantified. The model results are supported by comparison to available observations. We obtain an average global OXL net chemical production of 12.615\u2009\u00b1\u20090.064\u2009Tg\u2009yr\u22121 in EC-Earth, with glyoxal being by far the most important precursor of oxalic acid. In comparison to the ERA-Interim simulation, differences in atmospheric dynamics and the simulated weaker oxidizing capacity in EC-Earth overall result in a \u223c\u200930\u2009% lower OXL source. On the other hand, the more explicit representation of the aqueous-phase chemistry in EC-Earth compared to the previous versions of the model leads to an overall \u223c\u200920\u2009% higher sulfate production, but this is still well correlated with atmospheric observations. The total Fe dissolution rate in EC-Earth is calculated at 0.806\u2009\u00b1\u20090.014\u2009Tg\u2009yr\u22121 and is added to the primary dissolved Fe (DFe) sources from dust and combustion aerosols in the model (0.072\u2009\u00b1\u20090.001\u2009Tg\u2009yr\u22121). The simulated DFe concentrations show a satisfactory comparison with available observations, indicating an atmospheric burden of \u223c0.007\u2009Tg, resulting in an overall atmospheric deposition flux into the global ocean of 0.376\u2009\u00b1\u20090.005\u2009Tg\u2009yr\u22121, which is well within the range reported in the literature. All in all, this work is a first step towards the development of EC-Earth into an Earth system model with fully interactive bioavailable atmospheric Fe inputs to the marine biogeochemistry component of the model.

Soils store more carbon than other terrestrial ecosystems1,2. How soil organic carbon (SOC) forms and persists remains uncertain1,3, which makes it challenging to understand how it will respond to climatic change3,4. It has been suggested that soil microorganisms play an important role in SOC formation, preservation and loss5\uffe2\uff80\uff937. Although microorganisms affect the accumulation and loss of soil organic matter through many pathways4,6,8\uffe2\uff80\uff9311, microbial carbon use efficiency (CUE) is an integrative metric that can capture the balance of these processes12,13. Although CUE has the potential to act as a predictor of variation in SOC storage, the role of CUE in SOC persistence remains unresolved7,14,15. Here we examine the relationship between CUE and the preservation of SOC, and interactions with climate, vegetation and edaphic properties, using a combination of global-scale datasets, a microbial-process explicit model, data assimilation, deep learning and meta-analysis. We find that CUE is at least four times as important as other evaluated factors, such as carbon input, decomposition or vertical transport, in determining SOC storage and its spatial variation across the globe. In addition, CUE shows a positive correlation with SOC content. Our findings point to microbial CUE as a major determinant of global SOC storage. Understanding the microbial processes underlying CUE and their environmental dependence may help the prediction of SOC feedback to a changing climate.Soil organic carbon (SOC) is vital for terrestrial ecosystems, affecting biogeochemical processes, and soil health. It is known that soil salinity impacts SOC content, yet the specific direction and magnitude of SOC variability in relation to soil salinity remain poorly understood. Analyzing 43,459 mineral soil samples (SOC < 150 g kg\uffe2\uff88\uff921) collected across different land covers since 1992, we approximate a soil salinity increase from 1 to 5 dS m\uffe2\uff88\uff921in croplands would be associated with a decline in mineral soils SOC from 0.14 g kg\uffe2\uff88\uff921above the mean predicted SOC (SOC\uffc2\uffafc= 18.47 g kg\uffe2\uff88\uff921) to 0.46 g kg\uffe2\uff88\uff921belowSOC\uffc2\uffafc(~\uffe2\uff88\uff92430%), while for noncroplands, such decline is sharper, from 0.96 aboveSOC\uffc2\uffafnc= 35.96 g kg\uffe2\uff88\uff921to 4.99 belowSOC\uffc2\uffafnc(~\uffe2\uff88\uff92620%). Although salinity\uffe2\uff80\uff99s significance in explaining SOC variability is minor (<6%), we estimate a one SD increase in salinity of topsoil samples (0 to 7 cm) correlates with respectiveSOC\uffc2\uffafdeclines of ~4.4% and ~9.26%, relative toSOC\uffc2\uffafcandSOC\uffc2\uffafnc. TheSOC\uffc2\uffafdecline in croplands is greatest in vegetation/cropland mosaics while lands covered with evergreen needle-leaved trees are estimated with the highestSOC\uffc2\uffafdecline in noncroplands. We identify soil nitrogen, land cover, and precipitation Seasonality Index as the most significant parameters in explaining the SOC\uffe2\uff80\uff99s variability. The findings provide insights into SOC dynamics under increased soil salinity, improving understanding of SOC stock responses to land degradation and climate warming.

Manipulative experiments and observations along environmental gradients, the two most common approaches to evaluate the impacts of climate change on nutrient cycling, are generally assumed to produce similar results, but this assumption has rarely been tested. We did so by conducting a meta-analysis and found that soil nutrients responded differentially to drivers of climate change depending on the approach considered. Soil carbon, nitrogen, and phosphorus concentrations generally decreased with water addition in manipulative experiments but increased with annual precipitation along environmental gradients. Different patterns were also observed between warming experiments and temperature gradients. Our findings provide evidence of inconsistent results and suggest that manipulative experiments may be better predictors of the causal impacts of short-term (months to years) climate change on soil nutrients but environmental gradients may provide better information for long-term correlations (centuries to millennia) between these nutrients and climatic features. Ecosystem models should consequently incorporate both experimental and observational data to properly assess the impacts of climate change on nutrient cycling.

A thorough understanding of the implications of this for litter decomposition is essential to make predictions of soil-atmosphere carbon (C) feedbacks. Soil nitrogen (N) and C cycles naturally are interlinked, but we lack a detailed understanding of how insect herbivores impact these cycles. In a laboratory microcosm study, we investigated the growth responses of heterotrophic soil fungi and bacteria as well as C and N mineralisation to simulated defoliator outbreaks (frass addition), long-term increased insect herbivory (litter addition at higher background N-level) and non-outbreak conditions (litter addition only) in soils from a Subarctic birch forest. Larger amounts of the added organic matter were mineralised in the outbreak simulations compared to a normal year; yet, the fungal and bacterial growth rates and biomass were not significantly different. In the simulation of long-term increased herbivory, less litter C was respired per unit mineralised N (C:N of mineralisation decreased to 20\u2009\u00b1\u20091 from 38\u2009\u00b1\u20093 for pure litter), which suggests a directed microbial mining for N-rich substrates. This was accompanied by higher fungal dominance relative to bacteria and lower total microbial biomass. In conclusion, while a higher fraction of foliar C will be respired by insects and microbes during outbreak years, predicted long-term increases in herbivory linked to climate change may facilitate soil C-accumulation, as less foliar C is respired per unit mineralised N. Further work elucidating animal-plant-soil interactions is needed to improve model predictions of C-sink capacity in high latitude forest ecosystems.", "keywords": ["Ekologi", "0106 biological sciences", "Ecology", "herbivory", "Subarctic birch forest", "nitrogen mineralisation", "04 agricultural and veterinary sciences", "15.

However, it remains unknown how long-term river C fluxes change because of climate, land-use, and other environmental changes. Here, we investigated the spatiotemporal variations in global freshwater C cycling in the 20th century using the mechanistic IMAGE-Dynamic Global Nutrient Model extended with the Dynamic In-Stream Chemistry Carbon module (DISC-CARBON) that couples river basin hydrology, environmental conditions, and C delivery with C flows from headwaters to mouths. The results show heterogeneous spatial distribution of dissolved inorganic carbon (DIC) concentrations in global inland waters with the lowest concentrations in the tropics and highest concentrations in the Arctic and semiarid and arid regions. Dissolved organic carbon (DOC) concentrations are less than 10 mg C/L in most global inland waters and are generally high in high-latitude basins. Increasing global C inputs, burial, and CO2 emissions reported in the literature are confirmed by DISC-CARBON. Global river C export to oceans has been stable around 0.9 Pg yr-1.
