Neonicotinoid Levels Exceed EPA Benchmarks in Half of Waterways on Illinois Protected LandsNARA Subscribed
Neonicotinoids have become widely used pesticides due to their specificity for insects. We explored how these contaminants are distributed on protected lands within Illinois. We hypothesized that there would be lower insect biomass at sites with higher neonicotinoid concentrations which we expected to occur at sites with a higher surrounding proportion of agriculture. We predicted that neonicotinoid levels would be highest at...
Peripheral and disjunct populations are often the result of historic geological changes in the landscape and because of the long temporal span of colonization or vicariance, they are often genetically distinct and, when occupying small areas, vulnerable to population declines. In freshwater fishes, such populations are very susceptible to habitat destruction and environmental changes that could hasten extirpation. Because thes...
Differences in characteristics between naturalized threatened plants and other threatened plantsNARA Subscribed
Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown. So too does the set of characteristics that distinguishes such species from other threatened species. For vascular plant species, we combined information from databases...
"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BPNARA Subscribed
This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological variability. Our results show that two distinct handaxe forms were present in different areas...
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...
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 proportion of individuals that are found to have empty stomachs during a survey of a predator population's diet has been used as an indicator of the average individual's state of energy balance and of the degree to which its feeding rate (i.e., its functional response) is saturated with respect to prey availability. As such, the proportion of empty stomachs provides insights into the effects of prey on predators and vice v...
Congener Conflict: Invasive Barred Owl Landscape Use Across the Range of the Northern Spotted OwlNARA Subscribed
Aim To map the probability of landscape use of invading barred owls ( Strix varia ) across the range of the threatened northern spotted owl ( S. Occidentallis Caurina ) in the Pacific Northwest, USA , identifying environmental drivers of barred owl landscape use to inform targeted management interventions. Location Forests of the Pacific Northwest, USA. Taxon Barred Owl ( Strix varia ). Methods We deployed 4081 autonomous reco...
GloNAF is a continuously updated, curated compilation of alien naturalized vascular plant inventories for geographic regions worldwide. Building on its predecessor, GloNAF 2.0 now contains 16,429 taxa and introduces major updates, including the standardization of taxonomic names using the World Checklist of Vascular Plants (WCVP), removal of outdated records, and the net addition of 117,229 new records. These new entries have...
