Diversity and extracellular enzymatic activity of culturable yeasts isolated from soil in a Brazilian Amazonian rainforest biomeNARA Subscribed
The Amazon rainforest represents the largest and most biodiverse tropical rainforest in the world, comprising over half of the planet’s remaining rainforests. In this study, we investigated the yeast distribution in the soils in a Brazilian Amazonian rainforest biome. The collection sites included two upland forests, a black-water floodplain forest, and an Amazonian dark earth site. Yeasts were isolated using both enrichment a...
Quantitative Mineral Resource Assessment of Lithium Pegmatite Deposits in the Southern Appalachian OrogenNARA Subscribed
The first quantitative mineral resource assessment for undiscovered lithium pegmatite deposits in the southern Appalachian region of the United States was conducted. Permissive tracts for lithium pegmatite deposits were delineated by integrating lithological, tectonic, geochemical, geophysical and mineral occurrence data. Lithium pegmatite prospectivity of the tracts was ranked with simplified mappable criteria, including prox...
Quantifying Pathogen eDNA at a Trap‐and‐Haul Facility for Adult Chinook Salmon ( Oncorhynchus tshawytscha )NARA Subscribed
Adult Chinook salmon ( Oncorhynchus tshawytscha ) trap‐and‐haul operations exist in rivers across the Pacific Northwest with the objective of re‐establishing salmon populations above impoundments. These efforts are complicated by high prespawn mortality (PSM), which can hinder restoration by reducing reproductive success. Recent improvements at trapping facilities in the Willamette River Basin, Oregon, USA, may reduce PSM by s...
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...
Mechanisms driving variation in American marten winter rest site use across the Western Great Lakes RegionNARA Subscribed
At high latitudes, the thermal protection of snowpack is important for many small-bodied mammal species during the winter. As depth and persistence of snow changes due to climate change, species that rely on snowpack’s insulation must increasingly depend on alternative thermal refuges. For the American marten ( Martes americana ), winter rest sites are predominantly in ground microsites. In some regions, however, martens prima...
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...
Oxygen is fundamental to ocean biogeochemical processes, with deoxygenation potentially reducing biodiversity, and disrupting biogeochemical cycles. In recent decades, the global ocean oxygen concentration has been decreasing, but this decrease is underestimated in numerical ocean models by as much as 50 %. Mechanisms responsible for this deoxygenation include (i) solubility-driven deoxygenation due to ocean warming, and (ii)...
WaterLANDS: A Database of Carbon Stocks, GHG Fluxes and Biodiversity Indicators in Restored European WetlandsNARA Subscribed
Motivation Wetland restoration is expected to play an important role in helping Europe achieve its climate and biodiversity targets as stated in the European Green Deal. Restored wetlands sequester atmospheric carbon and provide habitat for a wide range of plant and animal species. To design effective, evidence‐based restoration targets and guide future projects, it is critical to understand the impacts of wetland restoration...
The Local Turn in a Global Sea: Identifying Sustainability Trade‐Offs in Regionalized Marine Aquaculture SystemsNARA Subscribed
Marine aquaculture, like the broader seafood industry, relies heavily on international trade and global supply chains for both production and sales. Recent global disruptions, including the COVID‐19 pandemic, the Russian invasion of Ukraine, the conflicts in the Middle East, and trade tensions, have exposed the social and economic vulnerabilities inherent in a globalized production system. In response, these events have sparke...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Predicting the progression of MCI and Alzheimer’s disease on structural brain integrity and other features with machine learningNARA Subscribed
Machine learning (ML) on structural MRI data shows high potential for classifying Alzheimer’s disease (AD) progression, but the specific contribution of brain regions, demographics, and proteinopathy remains unclear. Using Alzheimer’s Disease Neuroimaging Initiative (ADNI) data, we applied an extreme gradient-boosting algorithm and SHAP (SHapley Additive exPlanations) values to classify cognitively normal (CN) older adults, th...
An exploration of the perspectives of Dutch adults experiencing a genetic condition on human germline gene editingNARA Subscribed
Views of people with a genetic condition are crucial in deliberations on human germline gene editing (HGGE), but their perspectives are at risk to be devalued due to epistemic injustice and insufficient attention for the possible sensitivities surrounding HGGE. This study set out to explore the perspectives of people dealing with a genetic condition regarding HGGE, and the possible sensitivities surrounding this topic. We cond...
Few certainties exist regarding the optimal type, timing, or dosage of rehabilitation after stroke. Despite differing injury mechanisms and recovery patterns following ischemic and hemorrhagic stroke, most translational stroke research is conducted after ischemia. As we enter the era of personalized medicine, exploring subtype-specific treatment efficacy is essential to optimizing recovery. Our objective was to characterize co...
Species‐specific diatom dynamics shape their vertical distribution and export during bloom declineNARA Subscribed
The Southern Ocean is a critical region for global biogeochemical cycles, particularly for carbon dioxide uptake and organic carbon export, partly driven by extensive phytoplankton blooms. In naturally iron‐fertilized regions of this otherwise iron‐limited ocean, these blooms are primarily driven by diatoms. Variability in bloom occurrences on spatiotemporal scales makes it challenging to track and understand a bloom's decline...
