Fig. 5: Demographic scenarios used to simulate mSFSs in fastsimcoal 2.6 for common toad in Scandinavia.

A single postglacial route of Scandinavia is modelled in M1 and M2 and a dual postglacial route is modelled in M3–M6. Arrows indicate migration events and population divides occur at T3–T1. Populations are resized after each population divide.
