(A) Global map of Bd genotypes. Points within 100 m are dispersed to decrease overlap and demonstrate sampling effort; therefore, map point locations are approximate. Colors indicate major Bd lineage, circles are newly genotyped samples (n = 222), and squares are previously published Bd genotype data (n = 334; data from refs. 14–17 and 27). (B) Best scoring unrooted maximum-likelihood tree estimated from 172 concatenated nuclear loci (23,651 bp) and 100 bootstrap replicates performed in RAxML. Branches on phylogeny are colored by major Bd lineage. This tree includes newly sequenced samples with at least 84 loci (n = 131) and whole-genome data (n = 47). Nodes with bootstrap support <50 have been collapsed and nodes >70 bootstrap support are labeled. Phylogeny with tip labels is available in SI Appendix, Fig. S1.
