Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmonNARA Subscribed
Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g., juvenile development). Consequently, phenological studies often cannot discern whethe...
More inclusive conservation approaches are needed to achieve the dual goals of justice and sustainability. This imperative requires developing new strategies to adapt extant models like conservation-based tourism in protected areas to incorporate more plural perspectives. We studied guided tours in Tierra del Fuego National Park, Argentina to assess how nature and people-nature relationships were (re)produced. Specifically, we...
Soil and ruminant gut microbiomes in diverse pasture systems and regenerative agriculture: a reviewNARA Subscribed
Pasture systems strongly influence microbiome diversity in both soils and grazing ruminants, and their interactions through interconnected microbial exchange pathways. In temperate regions, grazed pasture systems are predominantly composed of perennial ryegrass-white clover, representing standard systems under contemporary management. However, sustainable alternatives such as regenerative agriculture, which emphasise diverse p...
Turbidity and streamflow as real-time indicators of microbial risk for aquatic recreatorsNARA Subscribed
Aquatic recreation is a popular pastime, but recreators often incur the risk of acquiring illnesses through exposure to waterborne pathogens. Several standards advise stakeholders on a waterbody’s recreational suitability using indicator bacteria concentrations. However, quantifying indicator organisms often takes several hours or days, resulting in a lack of real-time information. Microbe concentrations can also fluctuate dra...
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...
Background Despite important advancements in diagnostic modalities, routine use of therapeutic drug monitoring (TDM) and newer antifungal therapies, there is a paucity of contemporary data regarding clinical characteristics and outcomes of invasive aspergillosis (IA) in the United States. Methods Single-center, retrospective cohort study of hospitalized patients between 2015 and 2020, who had active hematological malignancy (H...
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...
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...
