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

Land 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

Synergistic and Trade‐Off Effects of Plant Communities on Slope Runoff and Sediment Yield

Land Degradation &Development, EarlyView.
ABSTRACT Plant community functional structure plays an important role in regulating slope runoff and sediment yield on the Loess Plateau. Based on runoff plot monitoring and vegetation surveys in the Yangjuangou catchment, we used partial least squares regression (PLSR) and variable importance in projection (VIP) analysis to assess the effects of ...

From Model to Practice: Testing Near‐Infrared Spectroscopy as a Bone Collagen Prescreening Tool

Archaeometry, EarlyView.
ABSTRACT Collagen is a vital archaeological material, preserving biochemical signatures that provide insights into past environments, diets, and human–animal interactions. However, diagenetic processes can lead to rapid and often inconspicuous degradation of collagen. Given the variability in collagen preservation and its significance for analyses such
