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.

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Organic Matter Quality and Microbial Activity in Soils Managed With Brachiaria Succession

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Although succession systems and brachiaria improve soil quality, gaps remain in microbial community dynamics, activity, and soil organic matter stocks. Methods The objective was to evaluate the carbon (C) and nitrogen (N) stocks of soil organic matter fractions and their distribution, molecular characterization, enzyme activity ...

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Stable isotope analysis of freshwater gastropod carbonates from Swanscombe: Insights into climate stability and seasonality during MIS 11c

Journal of Quaternary Science, EarlyView.
ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

Monitoring wolverine (Gulo gulo) distribution across the western United States for regional and national assessment

The Journal of Wildlife Management, EarlyView.
We estimated the distribution of the federally threatened wolverine (Gulo gulo) across the western United States in 2022, evaluated changes in distribution since 2017 (the last survey), and made inference on drivers of wolverine occurrence. This monitoring program and subsequent results are used by states to make management and conservation decisions ...

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

Land Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Seasonal Dynamics of Soil Multitrophic Biodiversity, Co‐Occurrence Network and Assembly Mechanisms Under Typical Vegetation Restoration Patterns in Karst Region

Land Degradation &Development, EarlyView.
ABSTRACT Previous studies often overlooked the dynamic effects of karst vegetation restoration on soil multi‐trophic biodiversity and the underlying community‐assembly mechanisms. To fill this gap, we performed a seasonal comparative analysis of soil biodiversity, co‐occurrence network architecture, and assembly processes across three representative ...

Forest Vapor Pressure Deficit Sensitivity: A Potential Indicator of Soil Carbon Stability Under Atmospheric Drying

Land Degradation &Development, EarlyView.
ABSTRACT This Short Report examines an underexplored link between atmospheric drying and soil organic carbon (SOC) stability. Rising atmospheric vapor pressure deficit (VPD) is becoming an increasingly important hydroclimatic stressor for terrestrial ecosystems.
