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,

Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute

Land Degradation Pathways of Open‐Pit and Underground Mining in Karst Regions: A Spatial Indicator Assessment

Land Degradation &Development, EarlyView.
ABSTRACT Mining in the karst regions of southwest China threatens ecosystem stability and accelerates land degradation. Regional evaluation rarely distinguishes between degradation pathways in open‐pit and underground operations, due to spatial heterogeneity and geomorphological confounding effects.

Forest Conversion Reduces Soil Water Retention in Tropical Rainforest

Land Degradation &Development, EarlyView.
ABSTRACT Extensive primary forests are being converted to secondary forests and plantations owing to human activities in recent decades, which have substantial effects on soil hydrological processes. However, the potential impact of forest conversion on soil water retention remains poorly understood.

Patterns and environmental drivers of root traits across hydrological gradients in old growth boreal forests

Oikos, EarlyView.
Many key ecosystem functions are affected by plant roots and their traits. However, understanding of the patterns in, and drivers of, root traits lags far behind equivalent knowledge of above‐ground tissues, particularly in boreal old growth forests. We surveyed community‐level root traits across 11 old growth forests spanning a wide latitudinal range ...

Nonlinear interactive effects of temperature and soil moisture on plant biomass and carbon fluxes

Oikos, EarlyView.
Climate warming is affecting plant growth and CO2 fluxes in high‐latitude ecosystems. However, soil moisture – and how it responds to warming – can alter the shape of the relationship between temperature and both plant performance and ecosystem processes. We conducted a microcosm experiment to test the interactive effects of temperature, soil moisture,
