Analyses of the ash dieback pathogen, H ymenoscyphus fraxineus , suggest role of tree species diversity on colonization and population structure differentiation

Summary Microsatellite markers were used to investigate the population structure of the Ash Dieback pathogen, Hymenoscyphus fraxineus, across a tree species diversity gradient containing common ash, Fraxinus excelsior, in the Hainich National Park in central Germany. Population differentiation was determined at a local spatial scale that may be driven by tree species mixtures.
