The University of Natural Resources and Life Sciences, Vienna, BOKU (Department of Forest and Soil Sciences; Institute of Forest Entomology, Forest Pathology and Forest Protection) in Austria is offering a 2- to 3-year PhD or post-doc position to study aspects of ash dieback, a serious disease of common ash (Fraxinus excelsior) and other Fraxinus spp caused by the invasive alien ascomycete fungus Hymenoscyphus fraxineus. The project aims at improving knowledge on the effect of admixed tree species on the intensity of ash dieback on common ash. The research will be conduced in three field experiments established in 2021 and 2022 where ash trees (reproductive material with putative higher disease resistance) have been planted in blocks (6 x 6 plants), purely and in equal mixture with various other tree species (24 in total). Another aim is to evaluate the susceptibility of various ash species and genotypes of common ash to ash dieback in existing field experiments. Applications will be accepted until the position is filled. Please find further information in the attached announcement. ================= Posted on behalf of Univ.Prof. Dipl.-Ing.
