Land-bridge calibration of molecular clocks and the post-glacial colonization of Scandinavia by the Eurasian field vole Microtus agrestisPhylogeography interprets molecular genetic variation in a spatial and temporal context. Molecular clocks are frequently used to calibrate phylogeographic analyses, however there is mounting evidence that molecular rates decay over the relevant timescales. It is therefore essential that an appropriate rate is determined, consistent with the temporal scale of the...
