Parsimony networks of select Atlantic reef fishes. Statistical parsimony networks representing relationships between: A. cytochrome b sequences of Halichoeres bivittatus haplotypes; B. cytochrome b of Halichoeres radiatus and H. brasiliensis; C. combined 16s and 12s sequences of Sparisoma axillare and S. rubripinne; D. combined 16s and 12s sequences of S. chrysopterum, S. frondosum and S. griseorubra. Sizes of ovals are proportional to haplotype frequency. Small empty circles represent missing haplotypes. Arrows indicate points of support for either the center of origin or the center of accumulation hypotheses. Colors as in Fig. 2.
