In July 2022, a harmful algal bloom of Heterosigma akashiwo originated in a man-made lagoon and expanded to more than 4,500 km² of open-water habitat in the San Francisco Estuary, triggering a widespread mass mortality event involving bony fishes, sharks, rays, crustaceans, mollusks, polychaetes, and jellyfish. Notably, the event affected the southernmost spawning populations of White Sturgeon ( Acipenser transmontanus ) and f...
Subnational entities such as states and provinces differ markedly in their material use, waste generation, and emissions due to variations in resource endowments, industrial structures, and living standards. These differences create distinct sustainability challenges that require regionally tailored policy responses. Yet, the development of comprehensive subnational datasets and indicators, including circular-economy metrics,...
Pacific white shrimp ( Litopenaeus vannamei ) are among the most important aquaculture species but are highly susceptible to Vibrio infections. Novel disease management strategies are necessary. Previous studies have reported that peracetic acid (PAA) is an effective disinfectant, but its application in shrimp aquaculture remains underexplored. This study aimed to determine the median lethal concentration (LC 50 ) of PAA at tw...
Dispersal and in Situ Speciation as Contributors to Plant Diversity in the Chocó Region: Insights From Inga Mill. (Leguminosae)NARA Subscribed
Aim To investigate the historical processes underlying the assembly of the flora of the Chocó region, with a focus on the relative contributions of dispersal and in situ speciation. Using Inga (Leguminosae) as a model lineage, we evaluate the origin and diversification of species present in the Chocó. Location The Chocó region, a lowland rainforest located across southern Panama, the Pacific coast of Colombia, the Magdalena hu...
Adverse childhood experiences, adult adiposity, and risk of young-onset breast cancer subtypes in a population-based case-control studyNARA Subscribed
Purpose Adverse childhood experiences (ACEs) are hypothesized to increase breast cancer risk via social and physiological pathways, yet associations between ACEs and young-onset breast cancer (BC) subtypes–and potential mediators (e.g., adiposity) of these associations–are largely unstudied. We sought to evaluate associations between ACEs and young-onset BC molecular subtypes, and the potential mediating effects of adiposity,...
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...
Early Imaging Biomarkers of Cartilage Strain After ACL Reconstruction Predict Patient Pain and Altered Knee LoadingNARA Subscribed
Purpose To investigate temporal evolution of cartilage strain and relaxometry following ACL reconstruction, and examine associations between MRI metrics, pain, and knee loading patterns during gait as potential early markers of cartilage degeneration. Methods Twenty-five participants (15 female, 10 male; mean age 25.6 years) undergoing ACL reconstruction completed MRI assessments at 6 and 12 month post-surgery, including displ...
Drought, Conflict and the Use of Historical Data and Methodologies in Interdisciplinary Palaeoclimatic ResearchNARA Subscribed
A major challenge in the interdisciplinary study of past climates is ensuring that evidence and data relating to different disciplines are analysed effectively using appropriate methodologies. In ‘Droughts and conflict during the late Roman period’, Clim. Chang 178, 2025, Norman et al. argue that historical sources support their conclusions that drought contributed causally to the ‘barbarian conspiracy’ of 367CE and to other l...
Understanding how physical transport mechanisms influence coral reef temperature dynamics is crucial for effective management. Typically, sea surface temperature (SST) is used to estimate coral heat stress, yet subsurface physical processes can significantly influence reef temperature dynamics and are imperative to consider in predictive efforts. Using observations and a 3D numerical model, we conducted a volume‐based temperat...
Aim The temperature‐size rule is often described as a reduction in ectothermic asymptotic or maximum body size with warming. Although this coincides with the expectation that faster growth under warming would lead to larger sizes early in life but smaller sizes later in life, there remain few tests of changes in size across ontogeny. Here, we use > 99,000 observations of weight‐at‐age of commercially important fishes over 25 y...
Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership of scientists and practitioners called the Shorebird Science and Conservation Collec...
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...
The volume of explosive products erupted during the ~ 1700 CE eruption of Sii Aks (Tseax), CanadaNARA Subscribed
Small mafic explosive eruptions are a globally common and frequent eruption type, and understanding the size of past eruptions is key to preparing for future impacts. However, Canadian volcanoes have received relatively little investigation due in part to their location in remote and challenging terrain. Here, we measured tephra thicknesses from 96 locations for the ~ 1700 CE eruption of Sii Aks (Tseax) in the Northern Cordill...
