Schematic overview of the discrete and continuous phylogeographic approaches that can be used to study the impact of environmental factors on a viral epidemic. Dispersion histories reported in both cases were informed by a consensus tree inferred from the discrete and continuous phylogeographic analyses based on the initial data set of Trovão et al. (2015) for West Africa (180 sampled RYMV sequences; see Section 2 for further details).
