Fig. 4From: Population genetics and phylogeography of Tabanus bromius (Diptera: Tabanidae)The results of the minimum spanning network analysis of the COI haplotypes of T. bromius using HapStar 0.7. Size of the circles is proportional to the frequency of the haplotype. The branch lengths are proportional to the number of hypothetical ancestors. Haplotypes are shown in Additional file 2: Table S2Back to article page
