Abstract excerpt
Rapid evolution through small shifts in allele frequencies at thousands of loci is a long-standing neo-Darwinian prediction but is hard to characterize in the wild. European ash tree (Fraxinus excelsior) populations have recently come under strong selection by the invasive fungal pathogen Hymenoscyphus fraxineus. Using genomic prediction models based on field trial phenotypes and 7985 loci, we show a shift in...
