Reconstruction of the dispersal history of viral lineages for two NRRs (NRR14 for SARS-CoV-1-like viruses and NRR37 for SARS-CoV-2-like viruses) obtained through continuous phylogeographic inference (seeData S2for all other NRRs). Nodes are colored from yellow (oldest MRCA) to blue (most recent collection date) and are superimposed on 80% HPD polygons colored according to the same log-transformed timescale, reflecting the uncertainty of the Bayesian phylogeographic inference. 80% HPD polygons were only computed and reported for the last 1,000 years. Dispersal direction (anti-clockwise) of viral lineages is indicated by the edge curvature. In (C), (D), (G), and (H), tip nodes are displayed as squares and are associated with a number indicating the host species from which the virus was sampled; internal nodes are displayed as circles. The host species are numbered by decreasing order of sampling frequency.
