A Generic Approach to Creating a National Soil Security Strategy

Sustainable Development, EarlyView.
ABSTRACT Soil is a living and non‐renewable resource that underpins our very existence. It produces our food, filters our water, stores vast amounts of carbon, cycles essential nutrients, and sustains the rich tapestry of biodiversity on which our planet depends.

AI‐Powered GPR Characterization of Peatland Underground Cavity Induced by Smoldering Wildfire: A Laboratory Proof‐of‐Concept

Safety Science and Technology, EarlyView.
We present an AI‐assisted ground‐penetrating radar framework to noninvasively detect and quantify smoldering wildfire‐induced subsurface cavities in peatlands. A ResNet model accurately predicts cavity geometry from GPR images, enabling improved assessment of underground fire damage and hazards.

Evaluating the Consistency of Radiometric Cross-Calibrated TOA Radiance Products Between Landsat-8 OLI and Landsat-9 OLI2

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
As China’s space technology rapidly progresses, the frequency of remote sensing satellite launches has significantly increased, elevating the demand for data consistency in integrated multiple sensors’ applications. Thus, the radiometric consistency of multiple sensors should be verified.

Evaluation of factors affecting greater prairie‐chicken nest and brood survival

Wildlife Biology, EarlyView.
Greater prairie‐chickens Tympanuchus cupido pinnatus in the Flint Hills ecoregion select recently burned grasslands for brooding and nest in areas that have been unburned for 1–3 years, suggesting the need for a mosaic of burn patches. However, it is unknown how patch area, configuration, and proximity to edges within such mosaics affect reproductive ...

Evaluating Google AlphaEarth and Landsat 8/9 Multisource Data Using Random Forest, Rotation Forest, and Canonical Correlation Forest for Enhanced Land Cover Classification

Nova Geodesia
Land cover classification is undergoing a major shift driven by advances in Earth observation and machine learning. While Landsat 8 and Landsat 9 continue to provide reliable, physically interpretable, and openly accessible multispectral data, emerging ...

Cryptic variation within and among islands in the ultraviolet reflectance of lizard throat coloration

Journal of Animal Ecology, EarlyView.
Identifying the existence of ‘cryptic’ morphs is critical in animal ecology for providing a basis for accurately testing links between phenotype and environment. This study identifies the existence of previously undocumented variation in UV reflectance in Aegean wall lizards that likely has novel behavioural and evolutionary implications within this ...

A Decadal Home‐Range Dynamics and Habitat Shift in Golden Snub‐Nosed Monkey (Rhinopithecus roxellana)

Integrative Zoology, EarlyView.
This study provides novel insights into the biogeographic patterns of the Sichuan golden snub‐nosed monkey, particularly in terms of habitat suitability and spatial‐use strategies. We found that habitat suitability has expanded over the past decade, with substantial shifts in the environmental factors influencing habitat suitability, from terrain and ...
