Acorn woodpeckers alter resource use, group size, and spring productivity across an urban landscapeNARA Subscribed
Access to suitable resources shapes the evolution and maintenance of avian cooperative breeding by influencing whether an individual will have a greater chance of survival and reproduction by dispersing or remaining on a natal territory. Cooperatively-breeding species exhibit altered dispersal according to food availability and habitat quality, but the relationship between resource use, group size, and reproduction in human-al...
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...
Many species within the family Moronidae possess biological traits that facilitate their success as invasive species in freshwater ecosystems. In Iowa, USA, non-native Yellow Bass (Morone mississippiensis) have expanded their range into at least 19 glacial natural lakes, yet their trophic interactions in these complex systems remain poorly understood. From 2018 to 2020, we evaluated the open-water diet composition of 1300 Yell...
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...
Habitat suitability model for identifying human-wildlife interface and implications for wildlife trade of Sunda pangolin in BorneoNARA Subscribed
Pangolins are the most trafficked mammals in the world. Sunda pangolins ( Manis javanica ), in particular, are critically endangered due to their proximity to consumption hotspots and the scale of the globalized illegal trade network. Data on their ecological drivers can inform targeted strategies to cauterize supply lines. We used data from 1455 camera-stations deployed between 2008 and 2024 across a heterogeneous mix of land...
Spatiotemporal Patterns and Drivers of Fish Biodiversity on a Remote Freshwater ArchipelagoNARA Subscribed
Aim Fish communities are shaped by environmental filters operating across different spatiotemporal scales. While many recent studies focus on anthropogenic gradients, few can isolate the role of natural drivers in community assembly. Isle Royale's inland lakes offer a rare opportunity to explore long‐term fish biodiversity dynamics with minimal confounding influences. We analysed fish communities in 23 lakes surveyed in the 19...
