Phylogeographic analysis. a) Maximum clade credibility tree. Branches are colored by most probable country location: blue for Uruguay, green for Brazil, and red for Argentina. Key nodes 1-7 are indicated (for which more information is available in Table 2). b) Population dynamics of BCoV in South America. The Bayesian skyline plot shows the evolution in population size. Median (dark line) and upper and lower 95% HPD (blue lines) estimates of effective population size (y-axis) through time in years (x-axis) are shown. c) The two entries of BCoV to Uruguay in 2013 are indicated with arrows: red from Argentina and green from Brazil
