PhD position on epidemiology of Chalara Ash Dieback

The objective of this project will be to better understand what conditions the production of inoculum of H. fraxineus in forest stand litter on a density gradient of the host, the ash tree. We will rely on two existing networks on which a strong relationship between host density and ash dieback severity has been identified (network of forest stands set up to study the effect of density and mixing on ash growth, network of stands on a locality to study the effect of the landscape on disease evolution).
