Purpose L-band passive microwave radiometry enables reliable soil moisture retrieval from satellites but at spatial resolutions too coarse for precision irrigation. Portable near-ground L-band radiometers offer a high-resolution alternative. This study evaluated a Portable L-band Radiometer (PoLRa) for estimating volumetric water content (VWC), comparing manufacturer-calibrated estimates with data-driven calibration approaches...
Dune Russet (COTX08063-2Ru) is the first French fry russet potato cultivar released by the Texas A&M Potato Breeding Program. It derives from a cross made by the Colorado State University Potato Program between Premier Russet and A99073-1 and was subsequently selected and advanced by the Texas Program. Dune Russet has oblong potato tubers with light russet skin texture and white flesh. It is characterized by having excellent F...
Productivity, Technical Efficiency, and Sustainability of Mechanized Potato Production: A Case Study of Tillage Service Users in KenyaNARA Subscribed
Potato ( Solanum tuberosum ) has a considerable potential to contribute to income generation and food security for smallholder farmers in Africa, but sustainable farming practices are required to exploit this potential. Kenya is an interesting example, as it is a leading potato producer in sub-Saharan Africa, but productivity has been declining in recent years. While past studies on potential reasons have focused on the use of...
Carbon source and weather in coastal North CarolinaNARA Subscribed
The increasing frequency of extreme weather events, including tropical cyclones, is altering the delivery and quality of organic matter (OM) exported from landscapes to estuaries. However, the mechanisms regulating these shifts, especially during multi‐year climatic oscillations, remain poorly understood. We used a new fluorescence–based mixing model to estimate dissolved OM (DOM) sources to the Neuse River Estuary, during a d...
Pacific Island Countries (PICs) are located in highly productive fishing regions that supply nutrient‐rich fish to global markets. Marine fisheries are a critical source of protein and essential micronutrients for billions of people worldwide, supporting both local diets and global food security. International trade shapes modern blue food systems, influencing broader distributions and availability of these ‘blue nutrients’. Y...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Shortleaf Pine (Pinus echinata): Management Challenges, Knowledge Gaps, and Opportunities for an Unsung SpeciesNARA Subscribed
Shortleaf pine has the broadest range of the southern pine species, occurring in 22 states and extending north into New Jersey, Pennsylvania, and New York (Staten Island). Shortleaf pine has been understudied compared to loblolly pine and longleaf pine, typically favored for timber production and conservation value, respectively. The extensive range of shortleaf pine contributes to a high degree of variability within and among...
Genetic Diversity Declines Toward Species' Range Edges, While Population Abundance and Growth Rate Show no Clear TrendNARA Subscribed
The centre‐periphery hypothesis (CPH) predicts that species exhibit higher abundance, demographic performance and genetic diversity at the centres of their geographic ranges than at their margins. This pattern is commonly attributed to stronger biotic interactions and declining habitat quality toward range edges. Recent reviews on the hypothesis assessed the prevalence of the centre‐periphery hypothesis using a vote‐counting a...
We announce the U.S. Geological Survey (USGS) Rotating X-ray Computed Tomography (RXCT) Coral-Core Archive, a digital resource derived from ~360 coral reef cores curated at the USGS Pacific and St. Petersburg Coastal and Marine Science Centers. The archive delivers calibrated 3-dimensional image volumes that enable reproducible values of skeletal density, linear extension, and calcification from decadal- to centennial-scale re...
