Fig. 2

The distribution of mitochondrial and nuclear variation within and among species. a–e Haplotype networks for each of five genes with the frequency of each haplotype within species indicated by colour coding. f Bottom panel—Structure plot of K = 3 model based on the nuclear data (bottom panel). Top panel—mitochondrial haplogroup (defined in a) of each individual indicated by bar colour. Bars are colour coded to reflect haplogroup origin: black—S. perrrico (A) red—S. rubroviolaceus (B), green—S. ghobban (C). White bars indicate individuals in which mtCR was not sequenced
