Figure S6
Illustration of phylogenetic relationship matrixes (Cacti) obtained from
Saguaro. Both horizontally and vertically the first samples are from the
west and then followed by the eastern samples. The horizontal and
vertical white lines separate the eastern from the western samples. The
yellow line separates the samples from Mexico from other samples. While
none of the relationships separated eastern and western monarchs, three
samples from Big Sur (visible as the differently shaded bands) appeared
to cluster together.
