Biodiversity is a major driver of numerous ecosystem functions. However, consequences of changes in forest biodiversity remain difficult to predict because of limited knowledge about how tree diversity influences ecosystem functions. Litter decomposition is a key process affecting nutrient cycling, productivity, and carbon storage and can be influenced by plant biodiversity. Leaf litter species composition, environmental conditions, and the detritivore community are main components of the decomposition process, but their complex interactions are poorly understood. In this study, we tested the effect of tree functional diversity (FD) on litter decomposition in a field experiment manipulating tree diversity and partitioned the effects of litter physiochemical diversity and the detritivore community. We used litterbags with different mesh sizes to separate the effects of microorganisms and microfauna, mesofauna, and macrofauna and monitored soil fauna using pitfall traps and earthworm extractions. We hypothesized that higher tree litter FD accelerates litter decomposition due to the availability of complementary food components and higher activity of detritivores. Although we did not find direct effects of tree FD on litter decomposition, we identified key litter traits and macrodetritivores that explained part of the process. Litter mass loss was found to decrease with an increase in leaf litter carbon:nitrogen ratio. Moreover, litter mass loss increased with an increasing density of epigeic earthworms, with most pronounced effects in litterbags with a smaller mesh size, indicating indirect effects. Higher litter FD and litter nutrient content were found to increase the density of surface\uffe2\uff80\uff90dwelling macrofauna and epigeic earthworm biomass. Based on structural equation modeling, we conclude that tree FD has a weak positive effect on soil surface litter decomposition by increasing the density of epigeic earthworms and that litter nitrogen\uffe2\uff80\uff90related traits play a central role in tree composition effects on soil fauna and decomposition.

Few studies have tested how plant quality and the presence of competitors interact in determining how herbivores choose between different leaves within a plant. We investigated this in two herbivorous spider mites sharing tomato plants: Tetranychus urticae, which generally induces plant defenses, and Tetranychus evansi, which suppresses them, creating asymmetrical effects on coinfesting competitors. On uninfested plants, both herbivore species preferred young leaves, coinciding with increased mite performance. On plants with heterospecifics, the mites did not prefer leaves on which they had a better performance. In particular, T.\uffc2\uffa0urticae avoided leaves infested with T.\uffc2\uffa0evansi, which is in agreement with T.\uffc2\uffa0urticae being outcompeted by T.\uffc2\uffa0evansi. In contrast, T.\uffc2\uffa0evansi did not avoid leaves with the other species, but distributed itself evenly over plants infested with heterospecifics. We hypothesize that this behavior of T.\uffc2\uffa0evansi may prevent further spread of T.\uffc2\uffa0urticae over the shared plant. Our results indicate that leaf age determines within\uffe2\uff80\uff90plant distribution of herbivores only in absence of competitors. Moreover, they show that this distribution depends on the order of arrival of competitors and on their effects on each other, with herbivores showing differences in behavior within the plant as a possible response to the outcome of those interactions.Global change is affecting soil biodiversity and functioning across all terrestrial ecosystems. Still, much is unknown about how soil biodiversity and function will change in the future in response to simultaneous alterations in climate and land use, as well as other environmental drivers. It is crucial to understand the direct, indirect\uffc2\uffa0and interactive effects of global change drivers on soil communities and ecosystems across environmental contexts, not only today but also in the near future. This is particularly relevant for international efforts to tackle climate change like the Paris Agreement, and considering the failure to achieve the 2020 biodiversity targets, especially the target of halting soil degradation. Here, we outline the main frontiers related to soil ecology that were presented and discussed at the thematic sessions of the World Biodiversity Forum 2022 in Davos, Switzerland. We highlight multiple frontiers of knowledge associated with data integration, causal inference, soil biodiversity and function scenarios, critical soil biodiversity facets, underrepresented drivers, global collaboration, knowledge application and transdisciplinarity, as well as policy and public communication. These identified research priorities are not only of immediate interest to the scientific community but may also be considered in research priority programmes and calls for funding.Soil erosion is one of the main threats driving soil degradation across the globe with important impacts on crop yields, soil biota, biogeochemical cycles, and ultimately human nutrition.

Objectives

Here, using an empirical model, we present a global and temporally explicit assessment of soil erosion risk according to recent (2001\uffe2\uff80\uff932013) dynamics of rainfall and vegetation cover change to identify vulnerable areas for soils and soil biodiversity.

Methods

We used an adaptation of the Universal Soil Loss Equation together with state of the art remote sensing models to create a spatially and temporally explicit global model of soil erosion and soil protection. Finally, we overlaid global maps of soil biodiversity to assess the potential vulnerability of these soil communities to soil erosion.

Results

We show a consistent decline in soil erosion protection over time across terrestrial biomes, which resulted in a global increase of 11.7% in soil erosion rates. Notably, soil erosion risk systematically increased between 2006 and 2013 in relation to the baseline year (2001). Although vegetation cover is central to soil protection, this increase was mostly driven by changes in rainfall erosivity. Globally, soil erosion is expected not only to have an impact on the vulnerability of soil conditions but also on soil biodiversity with 6.4% (for soil macrofauna) and 7.6% (for soil fungi) of these vulnerable areas coinciding with regions with high soil biodiversity.

Conclusions

Our results indicate that an increasing proportion of soils are degraded globally, affecting not only livelihoods but also potentially degrading local and regional landscapes. Similarly, many degraded regions coincide with and may have impacted high levels of soil biodiversity.Multiple ecosystem services (ES) can respond similarly to social and ecological factors to form bundles. Identifying key social-ecological variables and understanding how they co-vary to produce these consistent sets of ES may ultimately allow the prediction and modelling of ES bundles, and thus, help us understand critical synergies and trade-offs across landscapes. Such an understanding is essential for informing better management of multi-functional landscapes and minimising costly trade-offs. However, the relative importance of different social and biophysical drivers of ES bundles in different types of social-ecological systems remains unclear. As such, a bottom-up understanding of the determinants of ES bundles is a critical research gap in ES and sustainability science. Here, we evaluate the current methods used in ES bundle science and synthesize these into four steps that capture the plurality of methods used to examine predictors of ES bundles. We then apply these four steps to a cross-study comparison (North and South French Alps) of relationships between social-ecological variables and ES bundles, as it is widely advocated that cross-study comparisons are necessary for achieving a general understanding of predictors of ES associations. We use the results of this case study to assess the strengths and limitations of current approaches for understanding distributions of ES bundles. We conclude that inconsistency of spatial scale remains the primary barrier for understanding and predicting ES bundles. We suggest a hypothesis-driven approach is required to predict relationships between ES, and we outline the research required for such an understanding to emerge.

In this light, the present paper numerically addresses the interaction between a single cavitation microbubble and a nearby lipid vesicle of a similar size. A coupled fluid-structure interaction model is employed, from which three critical modes of vesicle deformation are identified and temporally placed in relation to their corresponding driving mechanisms: (a) unilateral stretching at the waist of the liposome during the first bubble collapse and subsequent shock wave propagation, (b) local wrinkling at the tip until the bubble rebounds, and (c) bilateral stretching at the tip of the liposome during the phase of a second bubble contraction. Here, unilateral and bilateral stretching refer to the local in-plane extension of the bilayer in one and both principal directions, respectively. Results are discussed with respect to critical dimensionless distance for vesicle poration and rupture. Liposomes with initially equilibrated envelopes are not expected to be structurally compromised in cases with \u03b4>1.0, when a nearby collapsing bubble is not in their direct contact. However, the critical dimensionless distance for the case of an envelope with pre-existing pores is identified at \u03b4=1.9.

Boreal forest soils store significant amounts of carbon and are cohabited by saprotrophic and ectomycorrhizal fungi (ECM). The \uffe2\uff80\uff98Gadgil effect\uffe2\uff80\uff99 implies antagonistic interactions between saprotrophic fungi and ECM. Plant photosynthates support the competitive fitness of the ECM, and may also shape the soil bacterial communities. Many \uffe2\uff80\uff98Gadgil effect\uffe2\uff80\uff99 experiments have focused on litter layer (OL) or have litter and root-fragments present, and thus possibly favor the saprotrophs. We compared how the restriction of plant roots and exudates affect soil microbial community structures in organic soil (mixed OF and OH). For this, we established a 3-yr field experiment with 3 different mesh treatments affecting the penetration of plant roots and external fungal hyphae. Exclusion of plant photosynthates induced modest changes in both fungal and bacterial community structures, but not to potential functionality of the microbial community. The microbial community was resilient towards rather short-term disturbances. Contrary to the \uffe2\uff80\uff98Gadgil effect\uffe2\uff80\uff99, mesh treatments restricting the entrance of plant roots and external fungal hyphae did not favor saprotrophs that originally inhabited the soil. Thus, we propose that different substrate preferences (fresh litter vs. fermented or humified soil), rather than antagonism, maintain the spatial separation of saprotrophs and mycorrhizal fungi in boreal forest soils.

Trait-environment relationships have been described at the community level across tree species. However, whether interspecific trait-environment relationships are consistent at the intraspecific level is yet unknown. Moreover, we do not know how consistent is the response between organ vs. whole-tree level.

We examined phenotypic variability for 16 functional leaf (dimensions, nutrient, chlorophyll) and wood traits (density) across two soil types, Ferralitic Soil (FS) vs. White Sands (WS), on two sites for 70 adult trees of Cecropia obtusa Tr\uffc3\uffa9cul (Urticaceae) in French Guiana. Cecropia is a widespread pioneer Neotropical genus that generally dominates early successional forest stages. To understand how soil types impact resource-use through the processes of growth and branching, we examined the architectural development with a retrospective analysis of growth trajectories. We expect soil types to affect both, functional traits in relation to resource acquisition strategy as already described at the interspecific level, and growth strategies due to resource limitations with reduced growth on poor soils.

Functional traits were not involved in the soil response, as only two traits-leaf residual water content and K content-showed significant differences across soil types. Soil effects were stronger on growth trajectories, with WS trees having the slowest growth trajectories and less numerous branches across their lifespan.

The analysis of growth trajectories based on architectural analysis improved our ability to characterise the response of trees with soil types. The intraspecific variability is higher for growth trajectories than functional traits for C. obtusa , revealing the complementarity of the architectural approach with the functional approach to gain insights on the way trees manage their resources over their lifetime. Soil-related responses of Cecropia functional traits are not the same as those at the interspecific level, suggesting that the effects of the acting ecological processes are different between the two levels. Apart from soil differences, much variation was found across sites, which calls for further investigation of the factors shaping growth trajectories in tropical forests.

Plant species diversity and identity can significantly modify litter decomposition, but the underlying mechanisms remain elusive, particularly for root litter. Here, we aimed to disentangle the mechanisms by which plant species diversity alters root litter decomposition. We hypothesised that (1) interactions between species in mixed communities result in litter that decomposes faster than litter produced in monocultures; (2) litter decomposition is accelerated in the presence of living plants, especially when the litter and living plant identities are matched (known as home\uffe2\uff80\uff90field advantage).

Monocultures and a mixture of four common grassland species were established to obtain individual litter and a \uffe2\uff80\uff98natural\uffe2\uff80\uff99 root litter mixture. An \uffe2\uff80\uff98artificial\uffe2\uff80\uff99 mixed litter was created using litter from monocultures, mixed in the same proportions as the species composition in the natural litter mixtures based on qPCR measurements. These six root litter types were incubated in four monocultures, a four\uffe2\uff80\uff90species mixture and an unplanted soil.

Root decomposition was strongly affected by root litter identity and the presence, but not diversity, of living roots. Mixed\uffe2\uff80\uff90species litter decomposed slower than expected based on the decomposition of single\uffe2\uff80\uff90species litters. In addition, the presence of living roots suppressed decomposition independent of the match between litter and living plant identities. Decomposition was not significantly different between the \uffe2\uff80\uff98natural\uffe2\uff80\uff99 and \uffe2\uff80\uff98artificial\uffe2\uff80\uff99 root litter mixtures, indicating that root\uffe2\uff80\uff90root interactions in species mixtures did not affect root chemical quality.

Synthesis. Suppressed decomposition in the presence of living roots indicates that interactions between microbial communities associated with living roots and root litter control root litter decomposition. As we found no support for the importance of home\uffe2\uff80\uff90field advantage or interspecific root interactions in modifying decomposition, suppressed decomposition of mixed\uffe2\uff80\uff90species litter seems to be primarily driven by chemical rather than biotic interactions.

The dependency of microbial activity on nutrient availability in soil is only partly understood, but highly relevant for nutrient cycling dynamics. In order to achieve more insight on microbial adaptations to nutrient limiting conditions, precise physiological knowledge is needed. Therefore, we developed an experimental system assessing traits of 16 saprobic fungal isolates in nitrogen (N) limited conditions. We tested the hypotheses that (1) fungal traits are negatively affected by N deficiency to a similar extent and (2) fungal isolates respond in a phylogenetically conserved fashion. Indeed, mycelial density, spore production and fungal activity (respiration and enzymatic activity) responded similarly to limiting conditions by an overall linear decrease. By contrast, mycelial extension and hyphal elongation peaked at lowest N supply (C:N 200), causing maximal biomass production at intermediate N contents. Optimal N supply rates differed among isolates, but only the extent of growth reduction was phylogenetically conserved. In conclusion, growth responses appeared as a switch from explorative growth in low nutrient conditions to exploitative growth in nutrient\uffe2\uff80\uff90rich patches, as also supported by responses to phosphorus and carbon limitations. This detailed trait\uffe2\uff80\uff90based pattern will not only improve fungal growth models, but also may facilitate interpretations of microbial responses observed in field studies.

Intrinsic water\uffe2\uff80\uff90use efficiency (iWUE) characterizes the physiological control on the simultaneous exchange of water and carbon dioxide in terrestrial ecosystems. Knowledge of iWUE is commonly gained from leaf\uffe2\uff80\uff90level gas exchange measurements, which are inevitably restricted in their spatial and temporal coverage. Flux measurements based on the eddy covariance (EC) technique can overcome these limitations, as they provide continuous and long\uffe2\uff80\uff90term records of carbon and water fluxes at the ecosystem scale. However, vegetation gas exchange parameters derived from EC data are subject to scale\uffe2\uff80\uff90dependent and method\uffe2\uff80\uff90specific uncertainties that compromise their ecophysiological interpretation as well as their comparability among ecosystems and across spatial scales. Here, we use estimates of canopy conductance and gross primary productivity (GPP) derived from EC data to calculate a measure of iWUE (G1, \uffe2\uff80\uff9cstomatal slope\uffe2\uff80\uff9d) at the ecosystem level at six sites comprising tropical, Mediterranean, temperate, and boreal forests. We assess the following six mechanisms potentially causing discrepancies between leaf and ecosystem\uffe2\uff80\uff90level estimates of G1: (i) non\uffe2\uff80\uff90transpirational water fluxes; (ii) aerodynamic conductance; (iii) meteorological deviations between measurement height and canopy surface; (iv) energy balance non\uffe2\uff80\uff90closure; (v) uncertainties in net ecosystem exchange partitioning; and (vi) physiological within\uffe2\uff80\uff90canopy gradients. Our results demonstrate that an unclosed energy balance caused the largest uncertainties, in particular if it was associated with erroneous latent heat flux estimates. The effect of aerodynamic conductance on G1 was sufficiently captured with a simple representation. G1 was found to be less sensitive to meteorological deviations between canopy surface and measurement height and, given that data are appropriately filtered, to non\uffe2\uff80\uff90transpirational water fluxes. Uncertainties in the derived GPP and physiological within\uffe2\uff80\uff90canopy gradients and their implications for parameter estimates at leaf and ecosystem level are discussed. Our results highlight the importance of adequately considering the sources of uncertainty outlined here when EC\uffe2\uff80\uff90derived water\uffe2\uff80\uff90use efficiency is interpreted in an ecophysiological context.

Over 50\uffe2\uff80\uff89years ago, Eugene Odum postulated that mature or climax forests reside in carbon neutrality. As climate change rose to prominence in the international environmental agenda, the neutrality hypothesis transformed from an ecological principle to a justification for using forest management in combating climate change. Despite persistent efforts, Odum's neutrality hypothesis has resisted both confirmation and refutation. In this opinion we show the limitations of past efforts to (in)validate Odum's neutrality hypothesis and propose new research directions for the community to permit a more general confirmation or refutation with current and near\uffe2\uff80\uff90future observations. We then demonstrate such an approach by using metabolic theory to formulate testable predictions for the total sink strength considering soil, litter, and biomass of mature or climax forests based on observations of tree biomass and individual density. In doing so, we show that ecological theory can create additional relevant, testable hypotheses to provide timely support to decision\uffe2\uff80\uff90makers seeking to address one of the world's most pressing environmental challenges.

Ecosystem water\uffe2\uff80\uff90use efficiency (WUE) is an important metric linking the global land carbon and water cycles. Eddy covariance\uffe2\uff80\uff90based estimates of WUE in temperate/boreal forests have recently been found to show a strong and unexpected increase over the 1992\uffe2\uff80\uff932010 period, which has been attributed to the effects of rising atmospheric CO2 concentrations on plant physiology.

To test this hypothesis, we forced the observed trend in the process\uffe2\uff80\uff90based land surface model JSBACH by increasing the sensitivity of stomatal conductance (gs) to atmospheric CO2 concentration. We compared the simulated continental discharge, evapotranspiration (ET), and the seasonal CO2 exchange with observations across the extratropical northern hemisphere.

The increased simulated WUE led to substantial changes in surface hydrology at the continental scale, including a significant decrease in ET and a significant increase in continental runoff, both of which are inconsistent with large\uffe2\uff80\uff90scale observations. The simulated seasonal amplitude of atmospheric CO2 decreased over time, in contrast to the observed upward trend across ground\uffe2\uff80\uff90based measurement sites.

Our results provide strong indications that the recent, large\uffe2\uff80\uff90scale WUE trend is considerably smaller than that estimated for these forest ecosystems. They emphasize the decreasing CO2 sensitivity of WUE with increasing scale, which affects the physiological interpretation of changes in ecosystem WUE.

Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, and soil properties. Datasets were required, at a minimum, to include abundance or biomass of earthworms at a site. Where possible, site-level species lists were included, as well as the abundance and biomass of individual species and ecological groups. This global dataset contains 10,840 sites, with 184 species, from 60 countries and all continents except Antarctica. The data were obtained from 182 published articles, published between 1973 and 2017, and 17 unpublished datasets. Amalgamating data into a single global database will assist researchers in investigating and answering a wide variety of pressing questions, for example, jointly assessing aboveground and belowground biodiversity distributions and drivers of biodiversity change.

Abstract. We studied nitrous oxide (N2O) fluxes and soil nitrogen (N) cycling following forest conversion to pasture in the central Amazon near Santar\uffc3\uffa9m, Par\uffc3\uffa1, Brazil. Two undisturbed forest sites and 27 pasture sites of 0.5 to 60 years were sampled once each during wet and dry seasons. In addition to soil-atmosphere fluxes of N2O we measured 27 soil chemical, soil microbiological and soil physical variables. Soil N2O fluxes were higher in the wet season than in the dry season. Fluxes of N2O from forest soils always exceeded fluxes from pasture soils and showed no consistent trend with pasture age. At our forest sites, nitrate was the dominant form of inorganic N both during wet and dry season. At our pasture sites nitrate generally dominated the inorganic N pools during the wet season and ammonium dominated during the dry season. Net mineralization and nitrification rates displayed large variations. During the dry season net immobilization of N was observed in some pastures. Compared to forest sites, young pasture sites (\uffe2\uff89\uffa42 years) had low microbial biomass N and protease activities. Protease activity and microbial biomass N peaked in pastures of intermediate age (4 to 8 years) followed by consistently lower values in older pasture (10 to 60 years). The C/N ratio of litter was low at the forest sites (~25) and rapidly increased with pasture age reaching values of 60\uffe2\uff80\uff9370 at pastures of 15 years and older. Nitrous oxide emissions at our sites were controlled by C and N availability and soil aeration. Fluxes of N2O were negatively correlated to leaf litter C/N ratio, NH4+-N and the ratio of NO3--N to the sum of NO3--N + NH4+-N (indicators of N availability), and methane fluxes and bulk density (indicators of soil aeration status) during the wet season. During the dry season fluxes of N2O were positively correlated to microbial biomass N, \uffce\uffb2-glucosidase activity, total inorganic N stocks and NH4+-N. In our study region, pastures of all age emitted less N2O than old-growth forests, because of a progressive decline in N availability with pasture age combined with strongly anaerobic conditions in some pastures during the wet season.

The Horizon Europe (HE) Mission \u201cA Soil Deal for Europe\u201d aims to accelerate the transition to sustainable soil and land management and healthy soils through an am-bitious transdisciplinary research and innovation (R&I) programme, largely based on actor engagement, Liv-ing Labs and Lighthouses. The H2020 Soil Mission Support (SMS) project supported the implementation of the HE Mission, and aimed to improve the coordination of R&I on sustainable soil and land management. Through a co-creation process together with actors, SMS collated available knowledge, actors R&I needs and identified R&I gaps that need to be addressed for successful transition towards sustainable soil and land management.
The first step was to identify existing R&I knowledge through a keyword-based analysis of scientific literature published and peer reviewed, related to sustainable soil and land management. The literature analysis ad-dressed the full range of societal challenges, soil health objectives, land use types and knowledge domains necessary to capture the socio-ecological complexity of soil health. Covering some 15,700 scientific articles, this literature analysis represents the current peer reviewed knowledge stock on sustainable soil and land management. A textual analysis using the digital platform CorTexT was undertaken to explore the identified literature and submitted to project consortium internal experts, who analysed and processed the collected information of their respective area of expertise (Annex III). The literature analysis revealed that the societal challenges \u201creduce soil degradation\u201d and \u201cimprove disaster control\u201d have been studied extensively. Con-versely, the societal challenges \u201cmitigate land take\u201d and \u201cincrease biodiversity\u201d and the knowledge domains \u201cscience-based policy support\u201d and \u201cawareness, training & education\u201d are less discussed. Factsheets present-ing the results of the literature analysis per societal challenge were developed and can be found in Annex VIII. Note that as the key-word based literature search was limited to Scopus-indexed scientific journals, other publishing formats such as conference papers, books, book chapters, non-digitalized articles, grey literature, reports, patents, etc., may be underrepresented or not included in the used data base. The exclusive use of Scopus-indexed scientific articles provided quality insurance of the material through the publication peer-review system. Nonetheless, important documents and knowledge have been incorporated by the consor-tium experts when analysing the collected literature.
The second step was to consult actors through online workshops and surveys in order to gain a practice-oriented \u2018real-life\u2019 picture of current knowledge and R&I needs for swift implementation of sustainable soil and land management. This step was seen as complementary of the published and peer-reviewed literature.
Finally, after exploring our stocktaking of R&I from existing knowledge evidenced by literature review and the actor\u2019s knowledge needs identified from actor consultations, we identified R&I gaps. The main knowledge gaps across all Mission Objectives were of socio-economic nature: drivers and causes of land degradation, knowledge management, governance and policies for inciting improved management, and interaction with other sectors are not sufficiently understood. Second, the HE Missions\u2019 focus on improving soil literacy was supported by the literature analysis and by the actor consultation, which both revealed knowledge gaps re-lated to education and capacity building in all land use types and domains affecting soil health: production, consumption, trade, policy and governance. Thirdly, there is a gap in the long-term implementation of a new mode of knowledge co-design, where researchers and practitioners together develop solutions for sustaina-ble soil and land management in a real-world context. The HE Missions\u2019 focus on Living Labs and Lighthouses has the potential to close this gap. Finally, there is a need to define several concepts (e.g. soil health, soil degradation, footprint). Such definitions should be shared and will be a basis to identify relevant indicators and respective thresholds, and to develop guidelines to support monitoring programmes in order to translate knowledge into evidence for decision making.
The outcome of the deliverable is a list of validated R&I gaps across all Mission Objectives which will feed into the SMS roadmap and the HE Mission.", "keywords": ["[SDE] Environmental Sciences", "2.

Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2\uffc2\uffa0m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic variables at a 1\uffe2\uff80\uff90km2resolution for 0\uffe2\uff80\uff935 and 5\uffe2\uff80\uff9315\uffc2\uffa0cm soil depth. These maps were created by calculating the difference (i.e. offset) between in situ soil temperature measurements, based on time series from over 1200 1\uffe2\uff80\uff90km2pixels (summarized from 8519 unique temperature sensors) across all the world's major terrestrial biomes, and coarse\uffe2\uff80\uff90grained air temperature estimates from ERA5\uffe2\uff80\uff90Land (an atmospheric reanalysis by the European Centre for Medium\uffe2\uff80\uff90Range Weather Forecasts). We show that mean annual soil temperature differs markedly from the corresponding gridded air temperature, by up to 10\uffc2\uffb0C (mean\uffc2\uffa0=\uffc2\uffa03.0\uffc2\uffa0\uffc2\uffb1\uffc2\uffa02.1\uffc2\uffb0C), with substantial variation across biomes and seasons. Over the year, soils in cold and/or dry biomes are substantially warmer (+3.6\uffc2\uffa0\uffc2\uffb1\uffc2\uffa02.3\uffc2\uffb0C) than gridded air temperature, whereas soils in warm and humid environments are on average slightly cooler (\uffe2\uff88\uff920.7\uffc2\uffa0\uffc2\uffb1\uffc2\uffa02.3\uffc2\uffb0C). The observed substantial and biome\uffe2\uff80\uff90specific offsets emphasize that the projected impacts of climate and climate change on near\uffe2\uff80\uff90surface biodiversity and ecosystem functioning are inaccurately assessed when air rather than soil temperature is used, especially in cold environments. The global soil\uffe2\uff80\uff90related bioclimatic variables provided here are an important step forward for any application in ecology and related disciplines. Nevertheless, we highlight the need to fill remaining geographic gaps by collecting more in situ measurements of microclimate conditions to further enhance the spatiotemporal resolution of global soil temperature products for ecological applications.Global change is affecting soil biodiversity and functioning across all terrestrial ecosystems. Still, much is unknown about how soil biodiversity and function will change in the future in response to simultaneous alterations in climate and land use, as well as other environmental drivers. It is crucial to understand the direct, indirect\uffc2\uffa0and interactive effects of global change drivers on soil communities and ecosystems across environmental contexts, not only today but also in the near future. This is particularly relevant for international efforts to tackle climate change like the Paris Agreement, and considering the failure to achieve the 2020 biodiversity targets, especially the target of halting soil degradation. Here, we outline the main frontiers related to soil ecology that were presented and discussed at the thematic sessions of the World Biodiversity Forum 2022 in Davos, Switzerland. We highlight multiple frontiers of knowledge associated with data integration, causal inference, soil biodiversity and function scenarios, critical soil biodiversity facets, underrepresented drivers, global collaboration, knowledge application and transdisciplinarity, as well as policy and public communication. These identified research priorities are not only of immediate interest to the scientific community but may also be considered in research priority programmes and calls for funding.

Few studies have tested how plant quality and the presence of competitors interact in determining how herbivores choose between different leaves within a plant. We investigated this in two herbivorous spider mites sharing tomato plants: Tetranychus urticae, which generally induces plant defenses, and Tetranychus evansi, which suppresses them, creating asymmetrical effects on coinfesting competitors. On uninfested plants, both herbivore species preferred young leaves, coinciding with increased mite performance. On plants with heterospecifics, the mites did not prefer leaves on which they had a better performance. In particular, T.\uffc2\uffa0urticae avoided leaves infested with T.\uffc2\uffa0evansi, which is in agreement with T.\uffc2\uffa0urticae being outcompeted by T.\uffc2\uffa0evansi. In contrast, T.\uffc2\uffa0evansi did not avoid leaves with the other species, but distributed itself evenly over plants infested with heterospecifics. We hypothesize that this behavior of T.\uffc2\uffa0evansi may prevent further spread of T.\uffc2\uffa0urticae over the shared plant. Our results indicate that leaf age determines within\uffe2\uff80\uff90plant distribution of herbivores only in absence of competitors. Moreover, they show that this distribution depends on the order of arrival of competitors and on their effects on each other, with herbivores showing differences in behavior within the plant as a possible response to the outcome of those interactions.

Plant species diversity and identity can significantly modify litter decomposition, but the underlying mechanisms remain elusive, particularly for root litter. Here, we aimed to disentangle the mechanisms by which plant species diversity alters root litter decomposition. We hypothesised that (1) interactions between species in mixed communities result in litter that decomposes faster than litter produced in monocultures; (2) litter decomposition is accelerated in the presence of living plants, especially when the litter and living plant identities are matched (known as home\uffe2\uff80\uff90field advantage).

Monocultures and a mixture of four common grassland species were established to obtain individual litter and a \uffe2\uff80\uff98natural\uffe2\uff80\uff99 root litter mixture. An \uffe2\uff80\uff98artificial\uffe2\uff80\uff99 mixed litter was created using litter from monocultures, mixed in the same proportions as the species composition in the natural litter mixtures based on qPCR measurements. These six root litter types were incubated in four monocultures, a four\uffe2\uff80\uff90species mixture and an unplanted soil.

Root decomposition was strongly affected by root litter identity and the presence, but not diversity, of living roots. Mixed\uffe2\uff80\uff90species litter decomposed slower than expected based on the decomposition of single\uffe2\uff80\uff90species litters. In addition, the presence of living roots suppressed decomposition independent of the match between litter and living plant identities. Decomposition was not significantly different between the \uffe2\uff80\uff98natural\uffe2\uff80\uff99 and \uffe2\uff80\uff98artificial\uffe2\uff80\uff99 root litter mixtures, indicating that root\uffe2\uff80\uff90root interactions in species mixtures did not affect root chemical quality.

Synthesis . Suppressed decomposition in the presence of living roots indicates that interactions between microbial communities associated with living roots and root litter control root litter decomposition. As we found no support for the importance of home\uffe2\uff80\uff90field advantage or interspecific root interactions in modifying decomposition, suppressed decomposition of mixed\uffe2\uff80\uff90species litter seems to be primarily driven by chemical rather than biotic interactions.

Over 50\uffe2\uff80\uff89years ago, Eugene Odum postulated that mature or climax forests reside in carbon neutrality. As climate change rose to prominence in the international environmental agenda, the neutrality hypothesis transformed from an ecological principle to a justification for using forest management in combating climate change. Despite persistent efforts, Odum's neutrality hypothesis has resisted both confirmation and refutation. In this opinion we show the limitations of past efforts to (in)validate Odum's neutrality hypothesis and propose new research directions for the community to permit a more general confirmation or refutation with current and near\uffe2\uff80\uff90future observations. We then demonstrate such an approach by using metabolic theory to formulate testable predictions for the total sink strength considering soil, litter, and biomass of mature or climax forests based on observations of tree biomass and individual density. In doing so, we show that ecological theory can create additional relevant, testable hypotheses to provide timely support to decision\uffe2\uff80\uff90makers seeking to address one of the world's most pressing environmental challenges.

The Horizon Europe (HE) Mission \u201cA Soil Deal for Europe\u201d aims to accelerate the transition to sustainable soil and land management and healthy soils through an am-bitious transdisciplinary research and innovation (R&I) programme, largely based on actor engagement, Liv-ing Labs and Lighthouses. The H2020 Soil Mission Support (SMS) project supported the implementation of the HE Mission, and aimed to improve the coordination of R&I on sustainable soil and land management. Through a co-creation process together with actors, SMS collated available knowledge, actors R&I needs and identified R&I gaps that need to be addressed for successful transition towards sustainable soil and land management.The first step was to identify existing R&I knowledge through a keyword-based analysis of scientific literature published and peer reviewed, related to sustainable soil and land management. The literature analysis ad-dressed the full range of societal challenges, soil health objectives, land use types and knowledge domains necessary to capture the socio-ecological complexity of soil health. Covering some 15,700 scientific articles, this literature analysis represents the current peer reviewed knowledge stock on sustainable soil and land management. A textual analysis using the digital platform CorTexT was undertaken to explore the identified literature and submitted to project consortium internal experts, who analysed and processed the collected information of their respective area of expertise (Annex III). The literature analysis revealed that the societal challenges \u201creduce soil degradation\u201d and \u201cimprove disaster control\u201d have been studied extensively. Con-versely, the societal challenges \u201cmitigate land take\u201d and \u201cincrease biodiversity\u201d and the knowledge domains \u201cscience-based policy support\u201d and \u201cawareness, training & education\u201d are less discussed. Factsheets present-ing the results of the literature analysis per societal challenge were developed and can be found in Annex VIII. Note that as the key-word based literature search was limited to Scopus-indexed scientific journals, other publishing formats such as conference papers, books, book chapters, non-digitalized articles, grey literature, reports, patents, etc., may be underrepresented or not included in the used data base. The exclusive use of Scopus-indexed scientific articles provided quality insurance of the material through the publication peer-review system. Nonetheless, important documents and knowledge have been incorporated by the consor-tium experts when analysing the collected literature.The second step was to consult actors through online workshops and surveys in order to gain a practice-oriented \u2018real-life\u2019 picture of current knowledge and R&I needs for swift implementation of sustainable soil and land management. This step was seen as complementary of the published and peer-reviewed literature.Finally, after exploring our stocktaking of R&I from existing knowledge evidenced by literature review and the actor\u2019s knowledge needs identified from actor consultations, we identified R&I gaps. The main knowledge gaps across all Mission Objectives were of socio-economic nature: drivers and causes of land degradation, knowledge management, governance and policies for inciting improved management, and interaction with other sectors are not sufficiently understood. Second, the HE Missions\u2019 focus on improving soil literacy was supported by the literature analysis and by the actor consultation, which both revealed knowledge gaps re-lated to education and capacity building in all land use types and domains affecting soil health: production, consumption, trade, policy and governance. Thirdly, there is a gap in the long-term implementation of a new mode of knowledge co-design, where researchers and practitioners together develop solutions for sustaina-ble soil and land management in a real-world context. The HE Missions\u2019 focus on Living Labs and Lighthouses has the potential to close this gap. Finally, there is a need to define several concepts (e.g. soil health, soil degradation, footprint). Such definitions should be shared and will be a basis to identify relevant indicators and respective thresholds, and to develop guidelines to support monitoring programmes in order to translate knowledge into evidence for decision making.The outcome of the deliverable is a list of validated R&I gaps across all Mission Objectives which will feed into the SMS roadmap and the HE Mission.", "keywords": ["[SDE] Environmental Sciences", "[SDE]Environmental Sciences", "577"], "contacts": [{"organization": "Mason, Elo\u00efse, L\u00f6bmann, Michael, Matt, Mireille, Sharif, Ibrat, Maring, Linda, Ittner, Sophie, Bispo, Antonio,", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/ftinraparis:oai:HAL:hal-04453703v1"}, {"rel": "self", "type": "application/geo+json", "title": "ftinraparis:oai:HAL:hal-04453703v1", "name": "item", "description": "ftinraparis:oai:HAL:hal-04453703v1", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/ftinraparis:oai:HAL:hal-04453703v1"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2023-01-01T00:00:00Z"}}], "links": [{"rel": "self", "type": "application/geo+json", "title": "This document as GeoJSON", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=577&f=json", "hreflang": "en-US"}, {"rel": "alternate", "type": "text/html", "title": "This document as HTML", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=577&f=html", "hreflang": "en-US"}, {"rel": "collection", "type": "application/json", "title": "Collection URL", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main", "hreflang": "en-US"}, {"type": "application/geo+json", "rel": "first", "title": "items (first)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=577&", "hreflang": "en-US"}, {"rel": "last", "type": "application/geo+json", "title": "items (last)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=577&offset=39", "hreflang": "en-US"}], "numberMatched": 39, "numberReturned": 39, "distributedFeatures": [], "timeStamp": "2026-04-17T13:07:38.874024Z"}
