Figure 1 in Helobdella stagnalis (Hirudinea: Glossiphoniidae), the first facultative mussel-associated leech in Europe
Figure 1. Map of collecting localities in the Volga and Don River basins, European Russia. The color filling indicate river basins: Don (1) and Volga (2). The red circles indicate localities in which freshwater mussels (Unionidae) were infested by the glossiphoniid leech species Helobdella stagnalis. The green circles indicate localities in which freshwater mussels were not infested by leeches. The yellow circles indicate the larger cities. The raw data on occurrence of leech and mussel host can be downloaded from figshare (Bolotov et al. 2022: Dataset 1).
Figure 4 in Helobdella stagnalis (Hirudinea: Glossiphoniidae), the first facultative mussel-associated leech in Europe
Figure 4. Median-joining haplotype network of Helobdella stagnalis based on the COI sequence data (N = 108 sequences; see Table 2 and Appendix 1 for detail). The red numbers near branches indicate the numbers of nucleotide substitutions between haplotypes. The circle size corresponds to the number of available sequences per haplotype (smallest circle = 1 sequence). The blue dashed circles reveal the three intraspecific mtDNA lineages.
