Fig. 4From: Phylogeography of the parasitic mite Laelaps agilis in Western Palearctic shows lineages lacking host specificity but possessing different demographic historiesHaplotype networks of 126 L. agilis specimens from the Western Palearctic and six L. clethrionomydis representatives from Russia reconstructed using a 381 bp fragment of COI. The parasite populations were categorized based on their geographic areas (A) and their hosts (B). Dash symbols and numbers next to each line indicate the number of mutational steps. The size of the circles is proportional to haplotype frequencies. Putative unsampled haplotypes are shown by black circles. Geographical distribution of the lineages is provided in Fig. 1Back to article page
