Fig. 2 in Trematode infection affects shell shape and size in Bulinus tropicus

Fig. 2. Haplotype network of the 227 Bulinus tropicus specimens from Lake Kasenda that were barcoded for a fragment of COX1. Circle area is proportional to the number of specimens of each haplotype (smallest circle = 1 specimen, largest = 104). Single nucleotide polymorphisms between the haplotypes are represented by dashes on the connecting branches. For each haplotype the proportion of snails that are uninfected or infected (any trematode infection), as derived from RD-PCR results, is indicated in grey and white, respectively. Labels refer to the haplotypes used in Supplementary Table 3.
