Incorporating Refugia Capacity in Assessing Plant Climate Vulnerability: A Study Case on Alpine Endemics

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This study assesses the impact of climate change on seven endemic plant species in the Alps by modelling future habitat suitability under different climate scenarios. By identifying long‐term refugia, holdouts and stepping stones, the study reveals species‐specific patterns of persistence and highlights the limited potential for range shifts.
