Distribution of mitochondrial haplotypes in a) arctic foxes and b) red foxes in regions defined by rabies strain distribution - North Slope region (arctic rabies variant 3) in red, Seward Peninsula region (arctic rabies variant 2) in green, and the Souwestern region (arctic rabies variant 4) in blue. The area of the pie charts are scaled to sample size. In red foxes only, samples were collected from two additional regions in Figure 3b – the Interior in yellow and Southcentral in orange. Major regional hub cities are marked with black stars, from west to east - Nome, Bethel, Barrow, Anchorage and Fairbanks.
