AbstractGenomic signatures of local adaptation have been identified in many species but remain sparsely studied in amphibians. Here, we explored genome‐wide divergence within the Asiatic toad,Bufo gargarizans, to study local adaptation and genomic offset (i.e., the mismatch between current and future genotype‐environment relationships) under climate warming scenarios. We obtained high‐quality SNP data for 94 Asiatic toads from 21 populations in China to study spatial patterns of genomic variation, local adaptation, and genomic offset to warming in this wide‐ranging species. Population structure and genetic diversity analysis based on high‐quality SNPs revealed three clusters ofB. gargarizansin the western, central‐eastern, and northeastern portions of the species' range in China. Populations generally dispersed along two migration routes, one from the west to the central‐east and one from the central‐east to the northeast. Both genetic diversity and pairwiseFSTwere climatically correlated, and pairwiseFSTwas also correlated with geographic distance. Spatial genomic patterns inB. gargarizanswere determined by the local environment and geographic distance. Global warming will increase the extirpation risk ofB. gargarizans.
