Latitudinal Clines in Gene Flow and Demographic Stability Reveal Drivers of Microendemism in a Radiation of Alpine Grasshoppers

open access: yesMolecular Ecology, Volume 35, Issue 7, April 2026.
ABSTRACT Understanding the geological, ecological, and microevolutionary processes that shape range size in alpine organisms is key to explaining the high rates of local endemism that characterise mountain ecosystems. Here, we investigate the geography of speciation in Oropodisma, a radiation of alpine grasshoppers from the Balkan Peninsula that ...

Dating C/S Structures in Syntectonic Granites by In Situ Rb‐Sr Analyses on Muscovite

open access: yesTerra Nova, Volume 38, Issue 2, Page 124-129, April 2026.
ABSTRACT The interplay of crystallisation, deformation and fluid–rock interactions makes deciphering geochronological information complex in syntectonic granites. In this study, we apply in situ Rb‐Sr analyses to selected samples from the Questembert Variscan syntectonic granite in Western France, which was emplaced along the South Armorican Shear Zone
