The hyperiid amphipod Brachyscelus rapacoides is a warm-water species associated with gelatinous zooplankton. In the Mediterranean it has been reported in association with Rhopilema nomadica in both Israel and Turkey. Here, we document the first record of B. rapacoides in Greek waters, representing the first confirmed record for Europe, based on both morphological examination and DNA barcoding of the mitochondrial COI gene. Sp...
Assessing Climate Adaptation Among Canada Lynx ( Lynx canadensis ) Populations at the Trailing EdgeNARA Subscribed
Species must acclimate, shift their distribution, or adapt in place in response to anthropogenic climate change. Populations at the low‐latitude trailing edge of the species distribution typically experience thermal conditions closest to the upper limit of their thermoregulatory capacity. Landscape and functional genomic approaches provide quantitative measures of risk and adaptive capacity which can inform and prioritise cons...
Sporecasting Biogeography Across Scales: Continental Patterns and Local Constraints on Macrofungal DispersalNARA Subscribed
Understanding how aerial fungal diversity varies across space, habitat, and disturbance is key to linking local‐scale sporocarp (fruiting body) reproduction with continental‐scale biogeography. In this study, we combined passive spore trap metabarcoding with macrofungal sporocarp records from 31 plots in eight sites across North America to quantify how site, habitat, and fire history shape aerial macrofungal communities. From...
We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee ( Oncorhynchus nerka ) at a given level of abundance by increasing the availability of Daphnia , an important food source. Age‐specific size (length, weight, and relative weight) and biomass were compared for periods with and without N addition....
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...
Environmental Variability Shapes Life‐History Trade‐Offs Within and Between Populations of a Long‐Lived SeabirdNARA Subscribed
Individuals face a trade‐off between allocating resources to reproduction or self‐maintenance, yet the drivers of the existence and strength of such trade‐off have been hard to determine. Environmental conditions are thought to play a crucial role, as long‐lived species are predicted to favour more precautionary life‐history strategies in variable environments. However, empirical evidence remains limited. Using long‐term monit...
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...
Huntington’s disease (HD) is a movement disorder commonly recognized as being neurodegenerative. An increasing number of studies also show primary HD dysfunction in multiple tissues, consistent with the widespread expression of the mutated huntingtin gene. Studies of HD skeletal muscle have revealed membrane hyperexcitability and prolonged action potentials due to Cl – and K + channel dysfunction as well as decreased Ca 2+ rel...
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...

Aridification Shaped the Diversification of Bothriembryon Land Snails in a Global Biodiversity HotspotNARA Subscribed
Aim Resolving the spatio‐temporal diversification patterns and systematic relationships of endemic Australian land snails against the backdrop of Neogene aridification through analyses of a combined nuclear and mitochondrial DNA sequence dataset. Location Western Australia. Taxon Mollusca, Stylommatophora, Bothriembryontidae, Bothriembryon. Methods We employed Bayesian Inference and Maximum Likelihood to reconstruct the phylog...
