Inter-plot competition in hybrid maize multi-environment yield trials in Ethiopia can reduce rate of genetic gainNARA Subscribed
Key messages The use of a competition model in the analysis of yield data from single-row hybrid maize METs improves the accuracy of genotype selection and thus the rate of genetic gain, while it ensures resource use efficiency in resource-constrained breeding programs. Abstract Conducting large-scale multi-environment trials (METs) is practically challenging to breeding programs in Sub-Saharan Africa due to limitations of lan...
Diversity and functional group composition drive biogeographic patterns in marine biogenic structural complexityNARA Subscribed
Biogenic structural complexity is a key driver of biodiversity and ecosystem functioning, yet its ecological and environmental determinants remain poorly understood across broad biogeographic scales. Here, we conducted standardized 90‐day field experiments at 16 coastal sites, spanning a 41‐degree latitudinal gradient, using naturally assembled marine fouling communities on settlement panels. We measured rugosity as our metric...
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...
National Poison Center Trends in GLP-1 Receptor Agonist Exposures Following FDA Approval for Weight LossNARA Subscribed
Introduction Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are therapies for type 2 diabetes whose use expanded sharply after semaglutide’s 2021 approval for obesity. Although gastrointestinal effects are well described, national patterns of acute GLP-1 RA exposures are poorly characterized. This study evaluated trends in GLP-1 RA exposures reported to U.S. poison centers, focusing on demographic shifts, exposure circu...
Non-native rusa deer ( Cervus timorensis ) were introduced to the 380-ha Wild Duck Island, an important flatback turtle nesting site in Broad Sound Islands National Park, Queensland, Australia, in the mid-2000s. Initial attempts to remove the population through ground and aerial culling (2007–2017) were unsuccessful. A more comprehensive eradication program commenced in 2018, employing aerial culling. In late 2019, a grid of 4...
Aim Biogeographical frameworks inform effective marine spatial planning, assessing ecological patterns across taxa and environments. In the Galapagos Archipelago, benthic bioregions guided marine reserve zoning, yet their representation of the mid‐water environment remains unassessed. Our study aimed to strengthen the understanding of patterns in marine biogeography in Galapagos by assessing whether the currently accepted bent...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
