Figure 3

Median-joining networks of the mtCOI and nuclear genes. Blue and red labels represent individuals sampled from the northern (9°50'N and 13°N) and southern (7°25'S-21°33'S) EPR, respectively. Sizes of haplotype circles and lengths of connecting lines are proportional to the number of sequences studied and the number of mutations that separate two linked haplotypes, respectively. Nuclear genes are rooted by a consensus outgroup sequence of A. caudata (connecting line between A. pompejana and the A. caudata outgroup is not representative of sequence differences due to the high number of mutations).
