Assembled and annotated reference genome and demographic history of the eastern chipmunk (Tamias striatus)NARA Subscribed
The eastern chipmunk ( Tamias striatus ) is an abundant North American sciurid rodent and the only extant member of the subgenus Tamias . Despite its abundance, a reference genome has not been produced for this species. Here we present an assembled and annotated reference genome for the eastern chipmunk using PacBio HiFi long read sequencing data. We sequenced the genome of a vouchered male eastern chipmunk collected in Maine...
Eelgrass (Zostera marina) can tolerate salinity fluctuationsNARA Subscribed
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...
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...
Practical application of BREAM2 in bystander/resident spray drift exposure assessments: accounting for variations in water volumeNARA Subscribed
The EFSA 2022 guidance on non-dietary human exposure, including operators, workers, residents and bystanders, relies on output from the original BREAM model, including simplified extrapolation for different application volumes. This study aims to present the current limitations and challenges in the European Plant Protection Product (PPP) authorizations for non-dietary exposure and risk assessments of residents and bystanders....
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...
The International Union for Conservation of Nature (IUCN) Green Status of Species (GSS), introduced in 2021, is a global standard of measurement used to assess the level to which a species has recovered (i.e., is viable and providing its ecological function across its entire range). It is also used to evaluate how a species has responded to past conservation actions and the expected conservation gains and recovery potential it...
A photophysiological model of coral bleaching simulates declines and recovery during an emulated multi-doldrum marine heatwave eventNARA Subscribed
Mass coral bleaching events have become increasingly frequent since the 1980s as sea surface temperatures have risen. Extremes of light and temperature stress leading to coral bleaching can develop when doldrum meteorological conditions occur during a marine heatwave event. The coral bleaching model simulates bleaching by tracking the build-up of reactive oxygen species driven by temperature-mediated, light-driven oxidative st...
The population of pillar coral, Dendrogyra cylindrus , in Florida was decimated from 2013 to 2020, primarily by the emergence of stony coral tissue loss disease (SCTLD). Monitoring of survivors from 2021 to early 2025 showed that the population underwent an additional 96% decline in live tissue, a 78% loss in living colonies, and a 55% loss of genotypes. SCTLD continued to be the primary cause of these losses. Although some su...
A decade of precursory seismicity at Mauna Loa: 2013–2022NARA Subscribed
