Fig. 5From: Does genetic structure reflect differences in non-breeding movements? A case study in small, highly mobile seabirdsMedian-joining networks. The networks are based on cytochrome b sequences from individuals belonging to Atlantic and Indian Ocean populations of blue petrels Halobaena caerulea, thin-billed prions Pachyptila belcheri and Antarctic prions P. desolata. The size of the circles is proportional to haplotype frequency. Hash-marks crossing line connections represent mutational stepsBack to article page
