1. From Reactive Remediation to Predictive Prevention: A Systems Synthesis of Global Soil Salinization and Sodicity.
PMID:日期:2026-10Soil salinization and sodicity are accelerating worldwide, reducing crop productivity across more than 160 million hectares of farmland and causing production losses approaching USD 27 billion annually. Despite decades of research documenting these impacts, the extent of salt-affected soils continues to expand. Salt-affected soil degradation emerges from feedbacks among physical, biological, and socioeconomic processes that operate across scales and resist intervention when addressed in isolation. This review synthesizes current understanding of these coupled feedbacks. We trace how ion accumulation, soil structural decline, microbial community disruption, and plant stress interact with irrigation practices, land use decisions, and governance systems. These interactions create threshold dynamics in which degradation can appear stable for years before rapid decline. Evidence from diverse regions reveals that effective restoration depends on coordinated interventions matched to the complexity of the system itself. Four research priorities emerge for advancing prediction and prevention. First, quantifying the thresholds that separate reversible from recalcitrant degradation across soil types and climates. Second, expanding predictive capacity through integrated sensor networks and data platforms that enable early warning. Third, improving understanding of how institutional structures influence adoption of restoration practices. Fourth, integrating biophysical and governance models to enable scaling from field trials to basin-wide implementation. By coupling mechanistic understanding with monitoring infrastructure and adaptive governance, reactive remediation can give way to proactive prevention.

2. Mineral Stabilization of Soil Organic Sulfur at the Continental Scale.
PMID:日期:2026-10Declining atmospheric sulfur (S) deposition makes S an emerging limiting macronutrient for plants, yet the stability and dynamics of soil organic S-the largest terrestrial S pool supplying plant-available sulfate via mineralization-remain unclear. Across North American soils, total organic S is dominated by mineral-associated organic S (MAOS; 61% ± 26%); this pool is stabilized by mineral protection but saturates at ~600 μg S/g soil. Compared with particulate organic S (POS), which is relatively labile and does not saturate, MAOS is more decomposed, chemically diverse, and climate-sensitive. Higher temperature accelerates S mineralization in both pools, but their ability to supply available S varies with moisture regime because MAOS stabilizes in wetter soils while POS remains labile. This continental-scale reassessment of the soil S cycle reveals that secondary minerals play a dual role in soil S cycling by stabilizing organic S and retaining sulfate, providing a mechanistic basis for nutrient management and carbon sequestration in response to climate change in an S-scarce future.

3. Forest Densification and Pollution Rival Climate in Driving US Tree Demographic Change.
3. 森林密度增加与污染在驱动美国树木种群变化方面可与气候相抗衡PMID:日期:2026-10Forests play critical roles in biodiversity, climate regulation, and human well-being, yet their responses to simultaneous environmental changes remain poorly understood. Across the United States, forest demographic rates are influenced by climate change, atmospheric pollution trends, and systematic changes in forest density. In spite of long-term interest in these facets of global change, their relative importance has not previously been quantified and compared. Here, we apply a framework that decomposes demographic trends into sensitivity (species' responsiveness to environmental variables) and exposure (magnitude of environmental change experienced). Using nationwide forest inventory data from 2002 to 2024, we analyzed how recruitment, growth, and mortality of 100 tree species responded to six environmental variables representing climate, pollution, and forest density. This analysis showed that, despite substantial research attention on climate impacts, changes in forest density and atmospheric pollutant deposition (particularly sulfur) showed stronger associations with all three demographic rates, driven by both higher exposure and greater sensitivity to these factors. We also found that, of the demographic processes, recruitment probability was the most sensitive to each of the six environmental drivers, emphasizing the importance of regeneration in shaping forest responses to global change. The results also document a general slowdown in forest dynamics over recent decades, with declining recruitment, growth, and mortality on average across the United States, albeit with substantial geographic and taxonomic variation. This comprehensive analysis provides a framework for understanding forest responses to complex environmental change, identifying the most influential drivers of demographic processes, and developing targeted conservation and management strategies in an era of rapid change.

4. Overwintering Strategies Drive Climate Change Impacts on Body Mass in Northern Mammals.
4. 越冬策略驱动气候变化对北方哺乳动物体重的影响PMID:日期:2026-09-30Climate change drives variable shifts in mammalian body sizes, yet the mechanisms underlying this variation remain unclear. Two explanations prevail: (1) higher temperatures reduce thermal constraints, favouring smaller bodies; or (2) warming enhances primary productivity, supporting larger bodies. We propose that species' overwintering strategies, which mitigate exposure to winter temperatures, determine which mechanism predominates. Using ~50 years of body mass data, we tested these hypotheses in three small mammals with contrasting natural histories in the rapidly warming Yukon, Canada. Snowshoe hares (Lepus americanus), exposed to ambient winter conditions, declined in mass over time and responded negatively to temperature and snow. In subnivean species, deer mice (Peromyscus maniculatus) showed no long-term trend but increased body mass with growing degree days, whereas red-backed voles (Clethrionomys rutilus) increased with temperature and snow. The results demonstrate that overwintering ecology mediates climate-driven body mass change, emphasizing the role of natural history in shaping species' responses to warming.

5. Physicochemical Protection Outweighs Microbial Carbon Use Efficiency in Regulating Soil Organic Carbon Across an Aridity Gradient.
PMID:日期:2026-09-30Microbial carbon use efficiency (CUE) has been proposed as a critical determinant of soil organic carbon (SOC) dynamics, yet its relative importance compared with plant carbon inputs, edaphic conditions, microbial attributes, and physicochemical protection remains poorly understood. Here, we conducted large-scale soil samplings across a 3000-km aridity gradient on the Tibetan Plateau to evaluate the contribution of microbial CUE to SOC variation. Microbial CUE increased with increasing aridity, whereas SOC declined, resulting in a weak negative relationship between CUE and SOC along the aridity gradient. This increase in CUE was primarily driven by reduced microbial respiration, while microbial growth remained largely unchanged. By contrast, correlation analyses revealed strong positive relationships between SOC and physicochemical protection, plant diversity and carbon inputs, edaphic properties, and microbial attributes. Random forest and structural equation models further showed that SOC variation was more strongly associated with indicators of physicochemical protection, including mineral-associated organic carbon, clay content, calcium-bound carbon, and microbial residue carbon than with microbial CUE. Together, our findings challenge the view that microbial CUE alone governs SOC accumulation and highlight the importance of stabilization processes in regulating SOC variations across the aridity gradient.

6. {"_":"Previously Unrecognized Land-Use Control on Deep Soil CO Sink.","sub":["2"]}
PMID:日期:2026-09-28Land-surface models commonly assume that soil CO production is rapidly transferred out of the soil profile, effectively equating respiration with near-surface signals. However, persistent subsoil CO enrichment despite limited in situ production reflects bidirectional exchange of topsoil-respired CO, suggesting that the surface-centric assumption may not be universally valid. Here we combine year-round, multi-depth field observations with process-based modeling (DeepCO) to quantify the effects of land use (croplands, forests, and forest-cropland edges) and climate on soil CO production-transport dynamics. We reveal pronounced vertical decoupling of soil CO, with deep CO (> 1 m) concentrations up to two orders of magnitude above surface concentrations and 9-17 times greater than can be explained by in situ production alone, revealing profile-scale production-transport imbalance. Forest soils promote ~2.3-fold greater deep CO accumulation than cropland and edge systems, driven by enhanced macroporosity and stronger advective coupling. Seasonal climate forcing regulates these regimes, with winter cold spells suppressing exchange, whereas spring-summer warming amplifies CO source strength originating from otherwise "protected" subsoil organic carbon, particularly in cropland and edge soils. These findings demonstrate that a substantial fraction of topsoil-respired CO is redistributed below the soil-atmosphere boundary and retained within the subsurface, forming a land-use-sensitive CO-C sink. Surface-based CO assessment therefore reflects a transport-limited, boundary-conditioned signal rather than a direct proxy for profile-scale production, and alone cannot resolve the full partitioning of soil-respired carbon. Incorporating depth-dependent production-transport coupling is therefore essential for accurately representing terrestrial carbon allocation and land-climate feedbacks under ongoing land-use change and climate warming.

7. {"_":"Water Table and Vegetation Shape Peatland CO and CH Fluxes With Water Table Modulating Temperature Sensitivity.","sub":["2","4"]}
PMID:日期:2026-09-28Peatland rewetting can reduce CO loss but increase CH emissions. How vegetation shapes this trade-off and how the water table modifies temperature sensitivity remain unclear. We analysed 14,643 observations from 285 peatland sites. CH emissions increased more steeply with rising water-table level (WTL) under graminoid dominance, while the pattern of declining ecosystem respiration differed between vegetation classes. Combined CO-equivalent emissions (GHGE; respiration + CH at GWP = 28) declined by 73.9% as WTL rose from 60 cm below to 15 cm above the peat surface and were still declining at the wet end of the analysed range. The decline persisted under GWP, although the magnitude of the decline above the peat surface depended strongly on the CH weighting. The within-site analysis further showed that apparent CH temperature sensitivity (Q) increased by 14.9% per 10 cm rise in WTL (95% CI 6.9%-23.5%), whereas respiration Q showed no detectable WTL dependence. A supplementary comparison within non-graminoid-dominated bogs showed that fitted CH Q increased with WTL where graminoids were present and decreased where graminoids were absent or negligible. Under +3°C warming, fixing CH Q at its value at WTL = -10 cm gave a predicted warming multiplier that was 24.7% larger at WTL = -63 cm and 11.8% smaller at +20 cm than the WTL-dependent formulation. These results suggest that assessments of peatland rewetting under warming should consider both vegetation differences in emission responses and the WTL dependence of CH temperature sensitivity.

8. Projecting Impacts of Marine Heatwaves and Their Effects on Long-Term Changes in Marine Ecosystems Over the 21st Century.
8. 预估21世纪海洋热浪的影响及其对海洋生态系统长期变化的效应PMID:日期:2026-09-27Marine heatwaves (MHWs) are increasing in frequency, duration and intensity under climate change. Although current MHWs trigger broad ecological impacts, such as coral bleaching, mass mortality of seagrass meadows, and declines in important fish stocks, the cascading effects of MHWs on ecosystem structure and functions in the 21st century remain unclear. In this study, we utilise a global biomass flow modelling framework to analyse these impacts. Leveraging climate projections from two Earth system models (ESMs), we project marine food webs dynamics at a spatial resolution of 1° latitude and longitude for the global ocean under a high-emission 'no mitigation' scenario, two MHW baseline definitions (fixed vs. moving baseline), and five organismal acclimation capacity scenarios to MHWs. We project that MHWs exacerbate declines in total consumer biomass under intensifying Global Warming Level (GWL), with spatial variations. Globally, under a scenario assuming a fixed baseline, MHWs' additional biomass decline increases with GWL at a rate ranging from 1.3% to 6.7% biomass loss per Celsius degree of warming, according to best-to-worst acclimation capacity scenarios to MHWs. Furthermore, the projected impacts of MHWs on marine biomass vary across the food web, with higher trophic levels being impacted by 0.8% more than lower trophic level compartments. Moreover, under a scenario that assumes a moving baseline, reflecting marine communities' capacity to adapt or acclimatise to climate change, the projected biomass loss from MHWs is reduced by an average of 3.7% per °C of global warming compared to fixed baseline simulations. We conclude that it is essential to incorporate extreme temperature events into climate change impact and risk assessments and examine the potential role of adaptive capacities of marine communities to inform robust climate responses and adaptations for biodiversity and fisheries. We emphasise that limiting global warming to below +2°C would significantly reduce MHWs' impacts.

9. Contrasting Energetic Pathways and Successional Trajectories of Soil Food Webs in Natural Succession and Reforestation-Based Restoration.
9. 自然演替与基于再造林恢复中土壤食物网能量途径与演替轨迹的对比PMID:日期:2026-09Forest restoration is increasingly recognised as a crucial strategy for mitigating biodiversity loss and enhancing ecosystem functioning in the face of global change. However, the long-term impacts of different restoration approaches, namely natural succession and reforestation, on the recovery of belowground food web function and energy fluxes remain poorly understood, despite the key role of decomposer food webs in the whole ecosystem. Here, we quantified energy fluxes in soil food webs across microfauna (nematodes) and macrofauna (microarthropods, earthworms) in 30-80-year-old sites under natural succession and reforestation, using a space-for-time substitution approach in southwestern China. We aimed to disentangle how natural succession and reforestation shape belowground energy fluxes and the community maintenance cost associated with sustaining soil animal biomass and biodiversity. We hypothesised that natural succession would be associated with lower maintenance costs than reforestation, while both approaches would follow similar trajectories of energy channelling underpinning belowground ecosystem functioning. Consistent with this hypothesis, natural succession had higher soil animal biodiversity (+50%) and biomass (+112%), while reducing community maintenance costs per unit biomass and biodiversity by 117% and 61%, respectively, compared to reforestation. The two restoration approaches showed divergent energy channelling over time: reforestation increased flux to higher trophic levels (a 5-fold increase in predation-to-basal consumption ratio, approaching natural forest) and shifted from detritivory- (brown) to herbivory-dominated (green) pathways, whereas natural succession enhanced fungal channels and faeces production with little change in predation or green-brown balance. We further found that reforestation increased energy flux primarily through greater litter biomass, whereas in natural succession, the increase was associated with litter quality and abiotic soil conditions. Overall, our findings highlight that natural succession, compared with reforestation, sustains soil communities at lower energetic costs and maintains belowground ecosystem functioning through more balanced and efficient energy fluxes.
