A framework for identifying paper parksNARA Subscribed
Modeling air temperature from snow-buried sensors to refine multi-decadal warming trends in Great Basin National Park, NV, USANARA Subscribed
Collecting reliable meteorological data in mountain environments is difficult because harsh conditions, complex terrain, and limited access disrupt long-term observations. In the Snake Range, Nevada, snow cover of low-cost temperature and humidity sensors creates winter gaps in near-surface air temperature records. To address this challenge, we developed three Random Forest Regression models to predict 2-m daily maximum, mean,...
Dryland ecosystems cover 41% of Earth's land surfaces, account for 44% of cultivated lands and 60% of food sources, and make large contributions to the global water and carbon cycles. However, these ecosystems are experiencing unprecedented extremes including heatwaves, floods, and droughts as well as hotter temperatures and often declining water resource availability. These ecosystems are some of the most challenging to monit...
Acoustic telemetry is a powerful tool for understanding spatial and temporal fish movements in complex freshwater systems but determining appropriate sample sizes for measuring individual variability in movement metrics is challenging. Here, the movements of 170 common bream Abramis brama were measured over two years in the highly connected River Bure wetland system, eastern England. Analyses of seasonal and spatial movement p...
Ocular Manifestations of Infectious Salmon Anaemia Virus Infection in Atlantic Salmon ( Salmo salar )NARA Subscribed
Eyes are essential sensory organs needed by teleost Atlantic salmon for high visual acuity and survival in both the wild and in aquaculture settings. In this work, we assessed the ocular manifestations of Infectious Salmon Anaemia Virus (ISAV) infection in Atlantic salmon by a cohabitation‐mediated infection assay and histological and immunohistochemical approaches. The findings reveal that Atlantic salmon with a systemic ISAV...
Population Genomics of a Cosmopolitan Weed Provides Insights Into Its Local Adaptation and Recent Demographic HistoryNARA Subscribed
Invasive plant species present a growing ecological and economic challenge, and often adapt rapidly to their novel environments through complex demographic and evolutionary processes. Invasion genomics offers powerful tools to disentangle these processes, but most studies rely on geographically narrow sampling across native and non‐native ranges. Erigeron canadensis is a cosmopolitan weed native to North America that has succe...
Capelin ( Mallotus spp.) are pelagic forage fishes that can be especially abundant in sub‐arctic marine ecosystems and are important prey for upper trophic‐level consumers. Abundance and distribution of capelin have been linked to ocean temperature, but the magnitude and directionality of thermal sensitivity can vary regionally. We used data spanning two decades (2002–2022) from autumn surface trawl surveys in three Alaska lar...
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...
Suburban land management impacts bee community composition and cucumber (Cucumis sativus) pollinationNARA Subscribed
Urban green spaces can provide quality habitat for insect pollinators. However, few studies have investigated the quality of pollination services provided by urban insect pollinator communities or compared pollination services between different types of urban green spaces. We evaluated both the taxonomic and functional trait diversity of flowering plant and bee communities in two common types of suburban green space: residenti...
Rethinking task failure in resistance training research: a framework for submaximal exercise prescriptionNARA Subscribed
Resistance exercise performed to task failure is often prescribed in muscle growth research to standardize effort and minimize between-participant variability. While effective for eliciting robust hypertrophic responses, this approach may also obscure meaningful differences attributable to manipulation of specific training variables, thereby reducing experimental sensitivity. The present perspective outlines a conceptual frame...
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...
