Management of community-acquired brain abscess and intracranial empyema: a survey of UK neurosurgical centresNARA Subscribed
Purpose We sought to describe current perceptions and attitudes to management of of brain abscess (BA) or sub-/extra-dural empyema (SDE/EDE) in the United Kingdom (UK) to compare this to the 2024 European Society of Clinical Microbiology and Infectious Diseases BA guidelines. Methods We conducted a web-based survey of infection specialists (IS) and neurosurgeons (NS) at neurosurgical centres across the UK. Results IS from 27/3...
Despite growing scientific evidence of the important role that wood-decomposing fungi serve in ecosystem function, we know little about how fungal community dynamics relate to decomposition outcomes. We deployed 42 standardized (same dimensions and source) wood stakes from sugar maple ( Acer saccharum ) and white ash ( Fraxinus americana ) on the forest floor of a northern US hardwood forest. After four years, we collected the...
The dispersal of ectomycorrhizal (EM) fungi is typically characterized by an ecological dichotomy in which aboveground (epigeous) mushrooms disperse via wind and belowground (hypogeous) truffles disperse via animal-mediated movement. To assess whether hypogeous EM fungi may be dispersed by wind more often than generally recognized, we used high-throughput sequencing of paired spore trap and soil samples at eight sites across t...
An experimental approach to assess the combined effects of multiple stressors on a large vertebrate speciesNARA Subscribed
The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure. The population of bottlenose dolphins in Barataria Bay, Louisiana, experienced long...
China seeks to expand forest-based carbon sinks, yet it remains unclear which pricing instruments and price levels deliver the largest additional sequestration under China’s land and governance constraints. We develop an evaluative framework that separates the extensive and intensive margins by pairing a province-level land-use share model for the extensive margin with a rotation model for the intensive margin, and benchmark a...
Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada. First observed in the Vermont portion of Lake Memphremagog, Vermont, USA and Quebec, Canada, the p...
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...
Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path ForwardNARA Subscribed
Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy. Underwater fish observation (UFObs) techniques, such as Underwater Visual Census (UVC), stereo‐Baited Remote Underwater Video (stereo‐BRUV) and Remotely Operated Vehicles (ROVs), play...
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...
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...
