Phylogeographic summaries: Left, cladograms; Right, maps. (A) Peromyscus eremicus group. (B) Chaetodipus baileyi group. (C) Chaetodipus arenarius. (D) Dipodomys merriami group. (E) Ammospermophilus. (F) Bufo punctatus. Capital letters after taxon names refer to areas as in Fig. 2B. Open circles in C and E signify localities at which both phylogroups occur. Trees shown here were produced with the neighbor-joining algorithm. Numbers along major branches refer to relative support for a clade out of 1,000 bootstrap pseudoreplications. Scale bars indicate 0.01 substitution per site.
