Maximum clade credibility trees constructed from the EACMV-like DNA-B Full genome (FG-B) dataset. Branches are coloured according to the most probable location state of their descendant nodes, with black circled nodes indicating nodes with state probabilities < 0.5. The time-scale of evolutionary changes represented in the tree is indicated by the scale bar below it. Whereas filled circles associated with nodes indicate > 95% posterior probability support for the branches to their left, open circles indicate nodes with > 70% posterior support for these branches. Nodes to the right of branches with < 70% support are left unlabelled. The bar graph on the left corner indicates the location probabilities of the node at the root of the tree that represents the most recent common ancestor of all the sequences represented in the tree. Grey bars represent the probabilities obtained with randomisation of the tip locations. Probable introduction events from Africa to the SWIO islands are indicated with red arrows.
