Figure
1. ML phylogenetic tree of the strain groups based on concatenated
sequences of seven Wolbachia genes (16S, MLST and wsp). Black
circles are nodes with bootstrap value > 95%.
Figure 2. Phylogenetic tree of Wolbachia strain groups (top) and
their scale insect hosts (left), with the black squares in the matrix
indicating which host species are infected with which Wolbachiastrain group(s). Colors in the phylogenies represent supergroups inWolbachia and host families, respectively. Host species are
represented by codes (for full species names please refer to File S2).
Figure 3. The effect of host
phylogenetic distance (left) and home range overlap (right)
on Wolbachia sharing probability. Points represent pairs of host
species that either share (1) or do not share (0) the sameWolbachia strain; the thick blue line represents the mean
predicted effect from our Wolbachia sharing GAMMs. The light blue
ribbon represents the 95% confidence intervals of that effect.
Phylogenetic distance is the sum of the branch lengths, i.e. the
estimated numbers of substitutions derived from the Maximum Likelihood
tree. Sharing decreased with both phylogenetic and geographic distance,
but the phylogenetic effect was significant and much steeper.
