Predictors of viral evolutionary rate from the Bayesian hierarchical phylogenetic model.

<p>(A) Effect sizes (<i>β</i>) on a log scale for each predictor were conditioned on the inclusion of that term in the model (i.e., <i>β</i> | <i>δ</i> = 1). Climatic region, coloniality, seasonal inactivity and long distance migration were categorical variables. Horizontal lines are the 95% highest posterior density intervals on conditional effect sizes and squares (median effect sizes) are proportional to effect sizes. (B) Violin plot showing the effect of climatic region on viral evolutionary rate. White points, black boxes and whiskers indicate the median, inter-quartile range and the total range of values for that group, respectively. The gray shading shows the probability density of evolutionary rate at different values.
