Using high‐density SNP genotyping to determine the origin of wild boar dispersers outside the geographic range margins in Norway

open access: yesWildlife Biology, EarlyView.
Mammalian dispersal is characterized by long‐distance movements, and whether dispersal is sex‐dependent and occurs at pre‐saturation densities affects colonization speed and concurrent pathogen spread. In Scandinavia, Sweden classifies wild boar Sus scrofa as a native species and retains high densities, while Norwegian authorities considers it an alien

Design of a time‐delay‐compensated monochromator for the ARPES endstation at S3FEL

open access: yesJournal of Synchrotron Radiation, EarlyView.
This work presents the design and expected performance of an Angle‐Resolved Photoemission Spectroscopy (ARPES) branchline at the Shenzhen Superconducting Soft X‐ray Free Electron Laser (S3FEL). The branchline employs a symmetric time‐delay‐compensated monochromator (TDCM) for spectral selection and pulse duration preservation.

Machine learning for orbit steering in the presence of nonlinearities

open access: yesJournal of Synchrotron Radiation, EarlyView.
A machine learning (ML)‐based method for beam orbit correction in circular particle accelerators is explored. Traditional correction techniques rely on the response matrix. Nonlinear elements, like those in the upcoming SLS 2.0 at the Paul Scherrer Institut, challenge the effectiveness of response‐matrix‐based methods.

Effects of short‐term multi‐pollutant exposure on the oxidative stress status of captive songbirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The human influence on Earth's ecosystems is omnipresent. Artificial light at night (ALAN), anthropogenic noise, and air pollution are inherent features of human activities and infrastructure and pose novel environmental challenges to urban‐dwelling wildlife.

Setting aside areas for conservation does not increase disturbances in temperate forests

open access: yesJournal of Applied Ecology, EarlyView.
We found no evidence that setting aside forests for biodiversity conservation amplifies disturbances in temperate forests of Central Europe. Conversely, we found that strict forest reserves had lower disturbance activity, particularly in years affected by severe climatic extremes.
