Figure 4 in Phylogeny and biogeography of African Biomphalaria (Gastropoda: Planorbidae), with emphasis on endemic species of the great East African lakes
Figure 4. Biogeographical hypothesis of the evolutionary history of the African Biomphalaria species. A, Pliocene– Pleistocene dispersal of a Biomphalaria glabrata-like snail into western Africa where the ancestral African Biomphalaria evolved, probably similar to Biomphalaria camerunensis/Biomphalaria pfeifferi. B. pfeifferi colonized most of the sub- Saharan continent. The ancestral African Biomphalaria or a B. camerunensis/B. pfeifferi-like stock migrated to East Africa and evolved into a Biomphalaria angulosa-like species, which is ancestral to the choanomphala-group snails. Within this species group the Ugandan Biomphalaria sudanica and Biomphalaria alexandrina evolved with B. alexandrina subsequently migrating along the River Nile to eastern North Africa. The river Nile and the surrounding region is indicated in the small inset.
Figure 3 in Phylogeny and biogeography of African Biomphalaria (Gastropoda: Planorbidae), with emphasis on endemic species of the great East African lakes
Figure 3. Consensus cladogram resulting from the parsimony and maximum-likelihood analyses of the combined matrix (16S, cytochrome oxidase subunit I, COI, and internal transcribed spacer I, ITS1). maximum-parsimony (MP) bootstrap values greater than 50% are positioned below the nodes, and the posterior probabilities from the Bayesian inference analysis are placed above the nodes. Species icons represent the typical morphology of the species. Species without country nomination are from Uganda. The 'Nilotic species complex' first inferred by DeJong et al. (2001) is indicated by the vertical bar. Note the basal position of Biomphalaria angulosa to the Nilotic species complex. The weak bootstrap support of this complex in the parsimony analysis is a result of the close phylogenetic relationship with B. angulosa.
Figure 2 in Phylogeny and biogeography of African Biomphalaria (Gastropoda: Planorbidae), with emphasis on endemic species of the great East African lakes
Figure 2. Plots of transitions (TS) and transversions (TV) for Biomphalaria relative to the percentage sequence divergence (p-distance). The sliding window analysis for noncoding sequences and codon position for protein coding sequences are given in the insets. A, TS/TV plot of the partial sequence of the mitochondrial 16S gene. Regions with the most variation are identified in the sliding window analysis and correspond to loop regions in the secondary structure. B, TS/TV plot of the total internal transcribed spacer I (ITS1) gene that indicates a possible saturation. The sliding window analysis (inset) illustrates that the variation is not distributed uniformly across the sequence. C, TS/TV plot of the partial sequence of cytochrome oxidase subunit I (COI; primer pair LCO/HCO). The codon position plot is given in the inset. D, TS/TV plot of the partial sequence of COI (primer pair ASMIT 1/2). The codon position plot is given in the inset.

C, Cladogram inferred from cytochrome oxidase subunit I (COI) by MP (primer pair LCO/HCO). D, Cladogram inferred from COI (primer pair ASMIT 1/2) by MP. E, Cladogram inferred from the combined data matrix by MP. F, Cladogram inferred from the combined data matrix by ML.
