Impact of Drone Versus Car Transport on Anti‐Doping Sample Integrity Over Short Distances: A Proof‐Of‐Concept Study

Drug Testing and Analysis, EarlyView.
This proof‐of‐concept study evaluated the impact of short‐distance drone transport on anti‐doping sample integrity compared with traditional car transport. Targeted assays and untargeted metabolomics revealed equivalent biological profiles between methods, confirming that drone delivery preserves sample integrity for the athlete biological passport ...

Spatial variation in liana effects on host‐tree allometry and biomass in an intact tropical forest

Ecography, EarlyView.
Lianas are increasing in abundance across the tropics, yet local spatial variation in their effects on host‐tree allometry and biomass, and the drivers of this variation within forests, remain poorly understood. Using field inventory, drone photogrammetry, and terrestrial laser scanning (TLS) across a 50‐ha plot on Barro Colorado Island, Panama, we ...

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

Aerial Seeding for Forest and Landscape Restoration: A Systematic Review of Technology, Challenges, and Future Directions

Land Degradation &Development, EarlyView.
ABSTRACT Land degradation is a critical global challenge, threatening biodiversity, food security, and livelihoods. Ecological restoration has therefore become a priority, with aerial seeding emerging as a key method to address issues of scale, accessibility, and efficiency. By dispersing seeds from aircraft or drones, aerial seeding complements ground‐

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.
