In East Africa, RYMV emerged in the 19th century after rice intensification along the Indian Ocean coast, and later spread inland concomitantly with rice introduction. In West Africa, the contrasted history of rice cultivation among regions differently shaped RYMV populations. A biogeographical approach - which jointly considers the spatial distribution of the virus and its hosts over time - was applied to reach these conclusions. We linked the evolution of RYMV over the past two centuries to a geographical map of the history of rice cultivation in Africa. specialized AFRIQUE DE L'EST AFRIQUE DE L'OUEST 076 082 10 7-13 2015 1879-6257 https://www.documentation.ird.fr/hor/fdi:010064089 10.1016/j.coviro.2014.12.002 1879-6257 [F B010064089] https://www.documentation.ird.fr/hor/fdi:010064089 https://www.documentation.ird.fr/intranet/publi/2015/05/010064089.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-06-04 2017-08-23 fdi:010064089 fre
