Fig. 2: Physical and genetic differences among parasite and host populations.

A schematic view of A Geographical distance among the sample sites, where direct distances between the sites are AM-LA = 9.2 km, CA-AM = 31.5 km, CA-LA = 33.5 km, B average pairwise relatedness (shown as 1-Φ) where Φ AM-LA = 0.244, CA-AM = 0.157, CA-LA = 0.162, C FST among parasites, from the three sample sites where, AM-LA = 0, CA-AM = 0.03, CA-LA = 0.03 and D SHUA among rats where, AM-LA = 0.21, CA-AM = 0.22, CA-LA = 0.15. Note that the scales of the metrics vary among the panels.
