Figure 1

Geographic location of the populations sampled and distribution of mtDNA haplotypes among islands, partitioned by Wolbachia infection status. Arrow heads indicate geographic origin of the samples. Sample number within each box corresponds to "Sample #" in Table 1. Within each island, the colours within bars indicate the relative proportion of haplotypes within each infection status. Numbers within bars indicate the number of specimens. u = uninfected, 1a = wBol1a, 1b = wBol1b, 2 = wBol2. Details on the distinction between wBol1a and wBol1b are given in the Results section, paragraph five.
