Synergistic polyreactivity of antibodies—where distinct oligo- or polyreactive clones combine to enable broad-spectrum antigen binding—was recently demonstrated for human anti-galactose-α-1,3-galactose (αGal) antibodies. However, it remains unclear whether this phenomenon also occurs in other antigen-defined antibody populations. Here, we investigated synergistic polyreactivity in isohemagglutinins (naturally occurring antibod...
Aims As the Arctic warms, evidence shows that warmer summers substantially affect ecosystem functioning, including carbon cycling. Yet, the most rapid warming occurs in winter, with more frequent mid-winter warming events raising air temperatures above 0 °C. During these warm spells, rain-on-snow events often generate extensive, long-lasting ice layers (icing) at the snow-ground interface, potentially altering tundra ecosystem...
Defaunation Maps for Tropical Mammals and BirdsNARA Subscribed
Motivation Overhunting is a major driver of defaunation in tropical ecosystems, yet its impacts and spatial extent remain challenging to quantify through conventional remote sensing approaches. Novel modelling frameworks based on quantitative relationships between impacts on wildlife populations and the main drivers of hunting pressure have provided a mean to identify hotspots of defaunation for avian and mammalian communities...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Environmental drivers of early life-stage survival are critical to understanding recruitment variability and improving ecosystem-based fisheries management. We investigate how regional ocean circulation influences blue whiting ( Micromesistius poutassou ) recruitment in the Northeast Atlantic by combining multi-decadal transport analyses with Lagrangian particle simulations. Using ocean reanalysis, we compute 28-year (1993-202...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Novel Method for Collecting Skin Microbiome Samples From Free‐Ranging Bottlenose DolphinNARA Subscribed
Cetacean skin microbiome samples are traditionally collected by swabbing the skin of captured animals or using skin tissue from remote biopsies. The effects of different sampling methods are not well understood, and factors such as swab type and storage methods may affect the microbiome. The objective of this study was to determine if samples collected by swabbing biopsied skin from bottlenose dolphins yield sufficient microbi...
Impact of Staphylococcus aureus colonization and skin abscesses on formation of human anti-αGal antibodiesNARA Subscribed
IgG antibodies against terminal galactose-α-1,3-galactose (anti-αGal antibodies) are naturally occurring in humans, but their origins remain poorly understood. These antibodies target various microorganisms including Staphylococcus aureus , a common nasal commensal and the major cause of skin abscesses. This study investigates the impact of S. aureus colonization and abscess events on plasma anti-αGal antibody levels. We measu...
The Importance of Being Consistent: Circularity Policy Aims in the European Wastewater SectorNARA Subscribed
The challenge of governing transitions towards circular economy cuts across different levels and sectors. However, existing literature has had scarce attention to the multi-level and multi-sectoral nature of circular economy governance. This article investigates these topics through a multiple case study of a little studied sector in the literature on the governance of circular economy: wastewater. The article analyses the con...
Key Message Perennial ryegrass shows extensive genotype x environment interactions at the limit of its ecological niche. Accounting for GxE may improve prediction even when environmental and genetic samples are highly diverse. Background In breeding the aim is to identify and accumulate beneficial variants. However, detection of these variants may be challenging in the presence of extensive genotype x environment interactions...
Carbon dioxide activated biochars as mediators for reductive debromination of 1,2-dibromoethaneNARA Subscribed
The fuel additive and pesticide 1,2-dibromoethane (DBA) is a problematic organic pollutant found in soil and aquifers. Remediation methods face drawbacks because of undesirable by-products and slow rates of removal. Biochars (BCs) are catalysts of reductive dehalogenation in anoxic environments by the layered iron(II)-iron(III) hydroxide green rust (GR). However, so far, such catalytic properties have generally only been obser...
