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...
Diagnosis of pneumococcal pneumonia using quantitative PCR targeting lytA and piaB in adult patients with community-acquired pneumoniaNARA Subscribed
Purpose Accurate diagnosis of pneumococcal pneumonia remains challenging due to suboptimal sensitivity of conventional microbiological methods. Molecular techniques may improve Streptococcus pneumoniae detection, but their clinical utility remains uncertain. Methods In this prospective observational study, we compared conventional diagnostics with qPCR-based detection of lytA and piaB genes in nasopharyngeal, oropharyngeal, sa...
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...
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...
Waterbird hunting is to be performed sustainably with respect to conservation status and animal welfare. Birds that are hit but not killed by shotgun pellets suffer what is called crippling. Here, we present data on crippling rates., i.e., the proportion of x-rayed birds with embedded shotgun pellets, of x-rayed individuals of nine waterfowl species in six European countries during 2017–2022. We x-rayed 3,843 individuals, of w...
Regulation of chemicals demands assessment of risks rather than identification of hazards onlyNARA Subscribed
This position paper was collaboratively written during the international expert symposium “EU Chemicals Assessment - Risk- or Hazard-based?” that was organised by the German Federal Institute for Risk Assessment (BfR) in Berlin on November 27th and 28th 2025. Twenty experts from several institutions and European countries considered the scientific merits of both hazard-based and risk-based approaches to chemical safety assessm...
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...
A multi-species model for goose management: Competition and facilitation drive space use of foraging geeseNARA Subscribed
Human-wildlife conflicts are generally tackled using single-species studies and ensuing management solutions, ignoring species interactions that may moderate or augment these issues. We investigate the effects of interactions between four goose species foraging in the province of Friesland, the Netherlands, on species distributions, energetics, and consequent economic costs of agricultural damages and management, using an indi...
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...
Pure mycelium materials (PMMs) are a sustainable alternative for a range of non-sustainable products such as textile, leather and meat. So far, properties of PMMs of different fungi have not been systematically assessed. Here, 11 mushroom-forming fungi, of which 10 isolated from nature, were grown in liquid shaken cultures. Schizophyllum commune, Ganoderma resinaceum , and Trametes betulina produced the highest biomass (8.62,...
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...
