Figure S7. Nuclear intron networks

Statistical parsimony networks of nuclear intron sequences: (a) 08352, (b) 09385, (c) 10179, (d) 11887, (e) 12884, and (f) 15349. Each circle represents a haplotype; the size of the circle is proportional to a haplotype’s frequency. Small black circles represent inferred haplotypes. Colors distinguish the four species recognized in this study.
