Figure S7: Patterns of empirical and simulated migratory connectivity and seasonal climate tracking. Top row: empirical patterns; second row: patterns simulated by ORSIM; third row: patterns simulated by the thermal tracking model; bottom row: patterns simulated by the precipitation tracking model;. Panels (a), (e), (i) and (m) show the connections between population migration destinations (i.e. migratory connectivity), and the other panels show the relationship between migration distance and (b,f,j,n) two-dimensional climate (temperature + precipitation), (c,g,k,o) thermal overlap (temperature only), and (d,h,l,p) precipitation overlap (precipitation only). Population acronyms are a combination of a latitudinal region: N=north and S=south; and a longitudinal region: W=west, R=Rockies, C=central and E=east. If no latitudinal letter is indicated in an acronym, it means that the population somewhat spans both north and south. If two longitudinal letters are indicated in an acronym, it means that the population somewhat spans both regions. Black curves are loess smooth splines with a span of 1.
