Figure 2. Demographic inference in UCSD juncos. Summary of the four demographic models and parameters implemented in fastSIMCOAL2 for likelihood comparison using genome-wide SNP data. Branch width represents population size. Values of T correspond to the present time (T0); a recent split/founder event about [20 - 100] generations ago (T1); and a postglacial split about [5 - 20] x103 generations ago (T2).
