Forest Pathology and Plant Health

Every year a number of new forest pathosystems are discovered as the result of introduction of alien pathogens host shifts and jumps hybridization and recombination among pathogens etc. Disease outbreaks may also be favored by climate change and forest management. The mechanisms driving the resurgence of native pathogens and the invasion of alien ones need to be better understood in order to draft sustainable control strategies. For this Special Issue we welcome population biology studies providing insights on the epidemiology and invasiveness of emergent forest pathogens possibly by contrasting different scenarios varying in pathogen and host populations size genetics phenotype and phenology landscape fragmentation occurrence of disturbances management practices etc. Both experimental and monitoring approaches are welcome. In summary this special issue focuses on how variability in hosts pathogens or ecology may affect the emergence of new threats to plant species.
