Appendix from P. A. Hohenlohe and S. J. Arnold, "MIPoD: A
Hypothesis-Testing Framework for Microevolutionary Inference from
Patterns of Divergence"
(Am. Nat., vol. 171, no. 3, p. 366)
Construction of the Phylogenetic Divergence Matrix
To further illustrate the construction of the phylogenetic divergence matrix A, we combine the G matrix shown
in figure 1A and the phylogeny shown in figure 2A. We thus have traits and taxa, so A will be am p 2 n p 3
6-by-6 matrix. First, the G matrix shown in figure 1A is parameterized by
S 5
p 0.6 , (A1)
J 0.8
so the 2-by-2 G matrix is
2.49 0.50
G p . (A2)
0.50 2.51
The matrix of shared ancestry T for the taxa x, y, and z is
t t t 1,000 200 200xx xy xz
T p t t t p 200 1,000 800 , (A3)yx yy yz
