Effect of Nanosilica Aggregates/Agglomerates on Functional Properties of Poly(Butylene 2,5‐Furandicarboxylate)‐Based Nanocomposites

open access: yesPolymer Composites, Volume 47, Issue 18, Page 16649-16665, 20 September 2026.
Effect of nanosilica aggregates/agglomerates on oxygen and water vapor diffusivity of PBF/SiO2 nanocomposites. ABSTRACT The nanofillers inclusions in poly(butylene 2,5‐furandicarboxylate) (PBF)/SiO2 nanocomposites were found to consist of aggregates and agglomerates of nanosilica particles.

Words That Warn: A Meta‐Analysis and a Systematic Review on How Media Exposure Shapes Natural Hazards Risk Perception

open access: yesJournal of Community &Applied Social Psychology, Volume 36, Issue 5, September/October 2026.
ABSTRACT The research examines how exposure to risk communication about natural hazards across different media is associated with risk perception of those hazards. Although risk perception is a key driver of protective and adaptive behaviours, evidence on the role played by exposure to risk communication through different media remains fragmented.

Sustainable Business Model Innovation and Firm's Performance: A Multiple Case Study in the Agri‐Food Industry

open access: yesCorporate Social Responsibility and Environmental Management, Volume 33, Issue 5, Page 6523-6539, September 2026.
ABSTRACT This research investigates how sustainability‐oriented initiatives aimed at innovating a firm's business model can lead to different economic, social and environmental performance configurations, with the objective of identifying the determinants that explain these differences. We carried out a multiple case study, selecting firms based on the

Genetic Structure and Signs of Local Adaptation in Icelandic Brown Trout Populations

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We present here an assessment of the genetic structure of Icelandic brown trout across 40 locations, revealing 16 distinct genetic clusters shaped by postglacial isolation and local adaptation. Our research highlights that landlocked headwater populations exhibit significantly reduced genetic diversity compared to anadromous groups and identifies ...

Long‐Term Temporal Change of Small Mammal Composition and Abundance in the Food Intake of the Western Barn Owl (Tyto alba), Comparing Two Different Lowland Mesoregions

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
The object of this study is to evaluate and compare the changes of the small mammal assemblages between two lowland mesoregions in Hungary based on Western Barn Owl pellet analysis. Prey composition, diversity, and community dynamics differed markedly between the two lowland regions, indicating that local landscape characteristics and weather ...

Unraveling the drivers of amphibian community distribution at a lowland–mountain interface: A joint modeling approach

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Understanding how environmental and biotic processes jointly shape species distributions and community composition is a central goal in ecology. Although species distribution models (SDMs) have become essential tools for quantifying environmental drivers of occurrence, their single‐species framework limits inference about interspecific ...

Neural Correlates of Fall Risk in People Aged 50 and Over With Chronic Low Back Pain: A Multimodal MRI Study

open access: yesEuropean Journal of Pain, Volume 30, Issue 8, September 2026.
ABSTRACT Background Chronic low back pain (CLBP) is common in older people and contributes to disability, physical inactivity, cognitive deficits and neural alterations that may increase fall risk. We examined associations between multimodal brain measures and daily‐life gait quality and other fall risk factors in older people with CLBP. Methods Thirty‐
