Patterns of Freshwater Fish Vulnerability in European Rivers
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.ABSTRACT European rivers are home to more than 600 native freshwater‐dependent fish species, with nearly half of them raising some level of conservation concern. Tackling this decline requires prioritising efforts towards the most vulnerable communities, at a spatial scale aligned with river restoration.

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Lake Salda (SW Turkey) is one of the most compelling terrestrial analogs for Jezero Crater on Mars due to its highly alkaline, Mg‐rich waters and hydromagnesite‐forming microbialites. This study integrates hydrochemical measurements, saturation‐index modeling, SEM–TEM imaging, and X‐ray diffraction (XRD) analysis to disentangle the biotic and ...

El Niño Events Enhance Melting of Sea Ice in the West of Greenland
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Using reanalysis data sets and numerical simulations, this study investigates the linkage between El Niño events and spring Arctic sea ice melt rate (AMR) in the west of Greenland. The results indicate that the accelerated spring AMR often corresponds to the previous winter's El Niño–like sea surface temperature anomalies.

Ecology and Evolution, Volume 16, Issue 4, April 2026.We reconstructed the postglacial recolonization history of Eurasian perch using mitochondrial and nuclear genomic data spanning Europe and Western Siberia. The analyses revealed multiple glacial refugia and extensive secondary admixture, reflecting a dynamic history of range expansion and contact among divergent lineages.
