Machine Learning‐Based Correction of Reanalysis Surface Radiation Fluxes Using Ground‐Measured Data in the Southern Brazilian Pampa Biome

International Journal of Climatology, EarlyView.
This study demonstrates that ERA5 provides more accurate surface radiation flux estimates than MERRA2 across the Southern Brazilian Pampa. Machine learning models, particularly Random Forest, further improved the precision of reanalysis data for climate applications.

Asynchronous Response of Plant Productivity and Soil Aggregate Nutrients to Grazing Exclusion Duration in Alpine Steppe

Land Degradation &Development, EarlyView.
ABSTRACT Grazing exclusion is a critical restoration measure for degraded alpine steppe ecosystems. However, research remains limited on the key factors influencing soil aggregates that affect plant productivity and the mechanisms influencing nutrient distribution across aggregates of different size fractions during long‐term grazing exclusion.

Afforestation Partially Offsets Losses of Soil Conservation Services and Carbon Stock From Direct and Indirect Urban Expansion in China

Land Degradation &Development, EarlyView.
ABSTRACT Urban expansion has exerted both direct and indirect impacts on natural land and ecosystem services it supports, driven by increasing population and food demand, yet these underlying pathways remain insufficiently distinguished. Here, we quantified the losses of soil conservation services (water erosion regulation and sandstorm prevention) and

Carbon–Phosphorus Limitation Is Associated With Shifts in Microbial Life‐History Strategies Across Vegetation Restoration Modes in Alpine Sandy Land on the Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Alpine sandy land on the Tibetan Plateau is fragile, with poorly developed soils, low nutrient availability, and weak biological resilience. Vegetation restoration is widely used to improve soil functioning, yet how microbial nutrient limitation and life‐history strategies vary among restoration modes remains unclear.

Post‐Fire Soil Organic Carbon Dynamics: Decline and Recovery Over Two Decades

Land Degradation &Development, EarlyView.
ABSTRACT Wildfire can significantly alter soil organic carbon (SOC) dynamics in forest ecosystems, with complex temporal patterns following fire events. However, research on post‐fire SOC recovery remains limited, particularly in dry‐warm valley regions that are prone to frequent forest fires.
