Significant non-zero HBV-D migration rates worldwide.

<p>Only the rates supported by a BF of >6 are shown. The relative strength of the support is indicated by the colour of the lines (from dark red = weak to light red = strong). The map was reconstructed using SPREAD (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0037198#s2" target="_blank">Methods</a>).</p

The maximum clade credibility (MCC) tree of HBV-D P gene sequences.

<p>The branches are coloured on the basis of the most probable location state of the descendent nodes (see colour codes in upper left inset). The numbers on the internal nodes represent posterior probabilities, and the scale at the bottom of the tree represents the years before the last sampling time (2007). The clades corresponding to the main HBV-D subgenotypes (D1, D2, D3, D5, D7) are highlighted.</p
