Schematics of fastsimcoal2 modeling scenarios. All italicized labels represent estimated parameters, except for the ancestral effective population size (N _ANC), which was set to 60,000 (see Methods). The rate of migration (m) is assumed to be directionally the same between population pairs. Each model has the same parameter values, though they vary in their order and/or representation. To crosswalk to K = 4 in Figure 4: N _WAS  = Wasatch sampling localities (red); N _EGB  = Eastern Great Basin (yellow); N _P/W  = Palouse/Wallowa (orange); and N _WGB  = Western Great Basin (blue)
