Figure 3. Molecular analyses among Biomphalaria populations (springs sampled in Salar de Carcote and Salar de Ascotán are numbered S1, etc.). A, tree obtained by maximum-likelihood (ML) analysis using mtDNA COI sequences. Identical topology was recovered in the maximum parsimony (MP) analysis. Numbers above the nodes indicate bootstrap values obtained under ML and MP analyses, respectively. The first number after the salt pan and species name indicates the specimen sampled. B, median-joining network of haplotypes obtained from Biomphalaria snails sampled in Salar de Carcote (C), Salar de Ascotán (A), and Isluga. The circle sizes are proportional to the number of observations of each haplotype. White circles represent missing haplotypes. The clades recovered by the phylogenetic analyses are also indicated.
