FIGURE 5 Ancestral area estimation of interspecific MOTUs (A–R) and lineages of Theodoxus obtained from BioGeoBEARS. Clades (C) and subclades (SC) are demarcated by dashed lines between MOTUs. Pie charts represent the relative likelihood of the lineage occurring within Anatolia (dark blue), occurring both within and outside of Anatolia (light blue) and just outside of Anatolia (grey). Small circles with the same colour scheme as the pie charts indicate the most likely state. The bars above the MOTUs represent their current distribution. Small squares at nodes indicate significant support of divergence events found with BEAST and other phylogenetic analyses (see Figures S2.1 and S2.2), as explained through the key. Cradle, museum and tap icons represent the relative contributions of functions (cradles, museums and sinks) at different points across the topology for Anatolian diversity. The grey shading indicates the period of pronounced glacial cycles (last 900 kyr) [Colour figure can be viewed at wileyonlinelibrary.com]
