Figure 4 in Microgeographic differentiation among closely related species of Biomphalaria (Gastropoda: Planorbidae) from the Andean Altiplano

Figure 4. Spatial genetic structure obtained in GENELAND (setting K = 4) for Biomphalaria snails (the springs sampled in Salar de Carcote and Salar de Ascotán are numbered S1, etc.). A, posterior probabilities of population membership in clusters 1–4 (from left to right, respectively). Lighter shading indicates higher probabilities of population membership. B, summary of estimated cluster membership of the four clusters and their respective localities. The black dots correspond to the localities analysed in this study.
