Description
Clément and a large team scan the genomes of wild beech trees where they grow in this 2026 study. Budbreak timing in European beech depends on both weather and genes, and previous garden experiments found only a few weak regions. Working in situ, in two range-edge populations surveyed over two years, avoids moving trees but exposes the full natural variation. The team ran genome-wide association tests linking DNA variants to budbreak in the field.
The significant DNA regions differed between the two populations and between years, evidence that local adaptation has occurred and that genes interact with the year's environment. Individual regions explained anywhere from almost nothing to over half the variation in some analyses. The architecture is mixed. Many effects are small, and a few are large. The diversity, the authors say, could feed assisted migration to prepare beech forests for climate change.
