Optimizing Soil Organic Matter Estimation Through Multi‐Factor Zoning and Tree‐Based Automated Learning

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil organic matter (SOM) is a key indicator of land degradation and soil functioning. It plays an essential role in nutrient cycling, soil structure, and long‐term agroecosystem resilience. The variations of surface cover, soil moisture and soil texture heterogeneity will affect the accuracy of SOM remote sensing mapping. This study developed

Contrasting Associations of Urbanization and Lateral Hydrological Gradients With Functional Structure and Rarity of Spontaneous Plants in River Corridors: Evidence From Changde, China

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
This study examined how urbanization and lateral hydrological gradients shape the functional structure and functional rarity of spontaneous plants in urban river corridors in Changde, China. Using field surveys, functional trait analysis, and structural equation modeling, we found that urbanization mainly affected communities through indirect pathways,

Do Shallow Slip Deficits Reflect Fault Structural Maturity or Modeling Choices? A Comparative Analysis of Tibetan Strike‐Slip Earthquakes

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).

Landslide‐Channel Coupling Controls Asymmetric Flash Flood—Debris Flow Transitions: Insights From an Extreme Rainfall‐Induced Hazard Chain in Yuzhong of China in 2025

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Extreme rainfall‐triggered landslide–flash flood–debris flow hazard chains (LFFDF) are increasingly responsible for hydroclimatic losses worldwide. Although dynamics of individual hazards are established, transition mechanisms within LFFDF governed by coupled landslide–channel responses remain unresolved.
