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...
Ecological seasonality describes the dynamic adaptation of species to changes in the biotic community and suggests predators should alter space use synchronously with seasonal prey availability. We assessed seasonal space use states (i.e., periods of similar movement and resource use) of mainland gray wolves ( Canis lupus ), moose ( Alces alces ), and white-tailed deer ( Odocoileus virginianus ) on the Grand Portage Indian Res...
Endemic species with narrow ranges are vulnerable to extirpation, and understanding their habitat needs is fundamental to effective management. The Etowah Bridled Darter, Percina freemanorum , is a recently described fish species endemic to the Upper Etowah River in Georgia. Little is known about how its habitat requirements differ from its sister taxon, P. kusha, with which it was previously synonymous . Our objectives were t...
Quantification and visualization of 3D facial aging in individuals of European ancestryNARA Subscribed
Facial features undergo continuous transformations across the lifespan. This study quantified and visualized the effects of aging on facial morphology in individuals of European ancestry. Three-dimensional facial photographs of 4,038 individuals (1,455 males and 2,583 females), aged 5 to 85 years and of European descent, were analyzed. Morphological changes in the face were modeled using kernel linear regression, with a focus...
Ocean dissolved oxygen (O2) is an essential climate variable crucial for sustaining the marine life; thus, changes of O2 at various spatiotemporal scales should be quantified and understood. Here, we study the climatology and annual cycle of O2 at regional to global scales using eight available gridded observational products. These datasets are generated by different groups using different primary data selection, quality contr...
Organic matter respiration stoichiometry in the Arctic Ocean is linked to shifts in plankton community compositionNARA Subscribed
The global rate of ocean deoxygenation may be influenced by the molar ratio of dissolved oxygen to organic carbon consumed during microbial respiration. However, respiration stoichiometry and its environmental controls are not fully understood due to sparse direct measurements and limited global coverage. Here, we measured surface concentrations of particulate chemical oxygen demand, particulate organic carbon, and particulate...
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...
