Soil CH4 and CO2 emissions mediated by water and afforestation in Horqin Sandy Land

Ecological restoration in arid and semi-arid regions plays a vital role in maintaining regional carbon balance under global change. Although water management and vegetation composition regulate soil carbon cycling, their combined effects on greenhouse gas source/sink dynamics in...

Evidence of vertical soil hydraulic heterogeneity regulating hydrothermal simulations in Qinghai–Tibetan Plateau wetlands

Abstract. Alpine wetlands on the Qinghai-Tibetan Plateau host vertically structured and highly contrasting pore systems that fundamentally shape land and atmosphere exchanges, yet their hydraulic expressions and process implications remain poorly quantified. This study provides t...

A standardized permafrost ground temperature collection for Canada 2025

Abstract. Ground temperature is an essential variable for monitoring the thermal state of permafrost, developing models, and conducting fundamental research. However, the usability of GT data in Canada is often hampered by inconsistent file formats, a lack of metadata standardiza...

Repeatable Velocity Fine Structure of Lightning K‐Leaders From a Single VHF Interferometer Made Three‐Dimensional

Abstract K‐processes re‐illuminate lightning channels at speeds of order 10 7 m s −1 , but measuring their three‐dimensional (3‐D) propagation velocity has required multi‐station systems available at few sites. An error‐isomorphism range inversion upgrades a single very‐high‐freq...

Applicability evaluation of thermal insulation for existing ballasted railway and its strengthening method in cold regions

Insulation boards are widely adopted to mitigate frost heave in cold-region subgrades. However, their effectiveness and applicability under shallow groundwater levels and high water contents remain insufficiently understood. In this study, a coupled moisture–heat–mechanical model...

Trajectory-SAM: Object Trajectory-Guided Segmentation for Remote Sensing Videos

The rapid proliferation of high-resolution remote sensing video (RSV) has made object segmentation an increasingly critical yet challenging task. Existing methods face two fundamental limitations in this domain: (1) the intrinsic complexity of RSVs arising from diminutive object...

Patch fragmentation accelerates alpine meadow degradation through altering soil water migration

The bidirectional coupling of hydrological and ecological processes is pivotal for maintaining ecosystem stability. Fragmented patch patterns are widespread in degraded alpine meadows worldwide, redistributing soil hydrothermal resources and potentially exacerbating ecosystem deg...

A Compositional and Genetic Framework for Shale Lithofacies Classification and Reservoir Quality Prediction: Insights From the Wufeng‐Longmaxi Formation, South Sichuan

ABSTRACT Although shales are of fundamental importance in geological research and energy exploration, no consensus has been reached on a unified classification and nomenclature that adequately reflect their multiscale heterogeneity and genetic origins. To address this gap, we pro...

Aridity regulates scale-dependent effects of multiple resource additions on productivity stability in Eurasian grasslands

Increasing the supply of multiple limiting resources generally reduces biodiversity and community stability in grasslands. Aridity is known to modify biodiversity-stability relationships, yet it remains unclear whether the effects of multiple resource supply on biodiversity and s...

Structure of Carbon Pools in Surface and Subsurface Horizons of the Main Soil Types in the Russian Arctic

Arctic and subarctic soils store approximately half of the global soil organic carbon (SOC) pool, yet the structural stability and vulnerability of these carbon reservoirs remain poorly constrained. Most regional assessments treat the cryopedosphere as a homogeneous entity, overl...

Decadal Dynamics of Air Temperature on the Southern and Northern Slopes of the Kunlun Mountains, Qinghai‐Tibet Plateau, and the Topographic Modulation Effects

ABSTRACT Topographic conditions are key factors governing surface energy distribution in high‐alpine mountainous areas, determining the dynamic variations of local climate and the thermal state of permafrost, which holds profound implications for understanding global climate syst...

The Altitude Effect of Stable Isotopes in Rivers Over the Tibetan Plateau

Abstract The altitude effect of stable isotopes in river water is key to paleoelevation reconstruction, yet remains poorly quantified at regional scales due to monitoring challenges. This study compiled river water isotope data across the Tibetan Plateau and used a decision‐tree‐...

Elevation-dependent regulation of alpine vegetation productivity by snow cover and grazing on the Tibetan Plateau under a warming–wetting climate

Grassland productivity on the Tibetan Plateau (TP) is fundamental to regional carbon cycling and ecosystem functioning and is strongly regulated by snow dynamics and grazing under a changing climate. However, the mechanisms by which alpine grassland productivity responds to inter...

Large-scale solar parks reshape ground arthropod assembly in the Tengger desert

The photovoltaic desertification control model effectively suppresses aeolian activity while promoting vegetation recovery and soil improvement, yet its impact on the diversity and function of ground arthropods remains unclear. This study was conducted at the Jiuduntan Photovolta...

The role of permafrost at Zonag Lake with its 2011 outburst: Insights from long-term and short-term perspectives

Lakes across the Qinghai-Tibet Plateau (QTP) are experiencing widespread and accelerated expansion, with Zonag Lake representing an extreme case following its catastrophic overflow and outburst in 2011. However, the characteristics and changes of permafrost extensively distribute...

Experimental warming alleviates leaf-level physiological stress of Kobresia pygmaea in alpine meadows on the Northeastern Qinghai-Tibet Plateau

Climate warming can strongly influence alpine plant physiology, but the leaf-level responses of dominant alpine meadow species to warming may vary across elevation and growing-season stages. These spatial and seasonal patterns remain insufficiently known. We examined the physiolo...

Topographic and economic drivers of agricultural–ecological coupling in Gansu Province: spatial differentiation and threshold effects

Improved understanding of agricultural–ecological coupling is critical for sustainable development in semi-arid regions. This study integrated the Remote Sensing Ecological Index (RSEI), Agricultural Green Development Index (AGDI), Coupling Coordination Degree (CCD) model, and XG...

Topological Reinforcement of Rhizosphere Microbial Networks Facilitates the Invasive Superiority of Spartina anglica

Rhizosphere microbial interaction patterns underpin the resilience and dominance of invasive plants in fluctuating coastal salt marshes. We compared the rhizosphere microbial communities of the invasive Spartina anglica and the native Spartina maritima across varying distances fr...

A comprehensive review on the incremental synthesis characteristics and regulation mechanism of natural gas hydrates enhanced by porous skeleton structure: challenges, perspectives and future directions

Natural gas has been widely regarded as a clean transitional fuel owing to its relatively low carbon intensity, high combustion efficiency and stable energy output. Hydrate-based natural gas storage and transportation has therefore attracted increasing attention as an emerging so...

Assessing ecosystem service values responses to livelihood transitions in an Arid Mountain–Oasis–Desert system

Balancing ecological conservation and rural livelihoods represents a critical challenge in arid social-ecological systems. Livelihood transitions among agropastoral households strongly influence the area allocated to different land-use types, thereby shaping regional ecosystem se...
