Phylogenetic trees based on Cyt b haplotypes. (a) Fifty percent majority-rule consensus of 6884 parsimonious trees based on 122 Cyt b unique haplotypes of P. nigromaculata (CI = 0.7621, RI = 0.9027). Numbers above branches are bootstrap values (1000 replicates). Letters or numbers in parenthesis indicate the population abbreviation and the quantity of individuals sharing the haplotype within each local population. The asterisk followed by an integer indicates the number of individuals sharing the haplotype among different populations (see Table 2 for details). (b) The concordant topology of maximum likelihood, maximum parsimony and neighbor-joining trees resulting from the reduced 49 exemplar ingroup taxa. Numbers above branches are ML bootstrap values (100 replicates); numbers below branches are MP/NJ bootstrap support values (1000 and 5000 replicates).
