Linking sources and sinks in the long distance aerial dissemination of ubiquitous pathogens
International audience The few cases where long distance aerial trajectories of plant pathogens from source to sink have been confirmed have specific traits: i) there are a limited number of sources, ii) sinks emerge along paths of air movement, and iii) sink and source populations have low enough g...
