Pollination Under Pressure: Grazing and Nutrient Enrichment Reshape Arctic Pollinator Communities and Interaction Networks

Global Change Biology, Volume 32, Issue 8, August 2026.
Grazing exclusion reshaped Arctic flower‐visitor communities, increased plant‐pollinator interactions, and altered interaction networks, while nutrient enrichment had weaker, context‐dependent effects. Together the two drivers produced both independent and interactive effects, with tundra grasslands showing the greatest sensitivity to environmental ...

Lost Gatherers in the 21st Century: Probability of Area, Spatial Behavior, Risk Factors and Vulnerability

Transactions in GIS, Volume 30, Issue 5, August 2026.
ABSTRACT Gathering activities have evolved from survival‐driven practices to predominantly recreational and cultural pursuits, weakening the connection with nature and potentially reducing navigational skills, which may help explain why gathering accounts for 8% of the search operations in Catalonia (Spain). A key focus of this study was the comparison

The Role of Gut Microbiota in Liver Regeneration After Partial Hepatectomy: New Evidence From Animal and Human Studies

The FASEB Journal, Volume 40, Issue 14, 31 July 2026.
Partial hepatectomy (PH) reshapes gut microbiota composition, resulting in the release of microbial metabolites and components, including short chain fatty acids (SCFAs)/β‐hydroxybutyric acid (BHB), bacterial DNA and extracellular vesicles (EVs), bile acids (deoxycholic acid, DCA), and aminobenzoate degradation products.

Influence of Emission Inventories and Secondary Organic Aerosol Chemistry on Simulated Fine Particulate Matter Over the U.S. in a Chemical Transport Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Accurately modeling ambient fine particulate matter (diameter <2.5 μm, PM2.5) is crucial to air quality management. We evaluate how uncertainties in biomass burning (BB) emissions, anthropogenic emissions, and secondary organic aerosol (SOA) production mechanisms impact simulated PM2.5 mass, composition, and statistical accuracy of modeled PM2.
