Network Map of the Atmospheric Transmission of Spores Causing Wheat Stem Rust (IMAGE)
Caption
(A) This is a long-distance dispersal network of spores between all major wheat producing countries in Southern/East Africa, the Middle East and Central/South Asia. Nodes represent countries; communities of the same colour indicate regions with high airborne connectivity; the size of nodes indicates node-strength; pie charts show the fraction of out-strength to total node strength (indicating donor and receptor countries). (B) Spore transmission frequencies along principal migration routes in the Rift Valley zone for the scenario of large outbreaks.
