Analysis of genetic adaptation in European beech reveals climate vulnerabilities, suggesting urgent conservation measures.

This research aims to quantify the minimum genetic change required for European beech to adapt to future climate scenarios.
Analyzed 18 populations of European beech across altitude gradients
Used landscape genomics and multiple Genotype–Environment Association approaches
Identified putative climate-associated genetic markers including 373 SNPs
Mapped genetic offset and Required Evolutionary Rate under future climate scenarios
Detected weak but structured genetic differentiation across populations
Uncovered maladaptation hotspots in Pyrenean and pre-Pyrenean regions
Found that climate gradients like drought and temperature significantly influence allele frequency changes
Proposed a new framework for assessing adaptation risks utilizing genetic offset and REvoRate

Morando‐Milà et al. (2026) studied this question.
