Native to China and Mongolia, the brown rat (Rattus norvegicus) now enjoys a worldwide distribution. While black rats and the house mouse tracked the regional development of human agricultural settlements, brown rats did not appear in Europe until the 1500s, suggesting their range expansion was a response to relatively recent increases in global trade. We inferred the global phylogeography of brown rats using 32 k SNPs, and detected 13 evolutionary clusters within five expansion routes. One cluster arose following a southward expansion into Southeast Asia. Three additional clusters arose from two independent eastward expansions: one expansion from Russia to the Aleutian Archipelago, and a second to western North America. Westward expansion resulted in the colonization of Europe from which subsequent rapid colonization of Africa, the Americas and Australasia occurred, and multiple evolutionary clusters were detected. An astonishing degree of fine-grained clustering between and within sampling sites ... : Puckett_etal_RatPhylogeog_SNPs.tarSNPs (l=32,127) discovered from a ddRAD-Seq project with Rattus norvegicus (n=314) and Rattus rattus (n=33) samples from around the world. SNPs are aligned to the Rattus norvegicus Rnor_6.0 genome and provided as binary PLINK files (.bed, .bim, .fam). See Tables S1 and S2 of the manuscript for locations for each sample name.Puckett_etal-RatPhylogeog-MitoHaplotypesMitochondrial SNP haplotypes produced from ddRAD-Seq data. We identified 104 haplotypes in 144 brown rat (Rattus norvegicus) samples, that group into 10 clades. SNP positions found in Table S3 of the manuscript.
