Fig. 5. Clustering of 12 populations of Thomomys umbrinus along the Mexican Transvolcanic Belt, according to sex (♀♀/33) and age (2, 3). Arrows show the comparisons of the phenograms using Mantel's Z tests (r = correlation; p = significance). Cophenetic coefficients are r = 0.8728 in ♀2; r = 0.8345 in ♀3; r = 0.9150 in 32; r = 0.8062 in 33.
