Figure 9.

Schematic representation of the evolutionary history of Galemys pyrenaicus. The grayed area represents the historical species distribution. Sampled areas of the four mitochondrial lineages are shown in different colors. Hypothetical positions of glacial refugia are illustrated with dotted circles within the current distribution of each mitochondrial lineage. The size of the circles represents the relative importance of the refugia. Arrows indicate colonization routes from these refugia.
