Figure 1

Map of sampling localities for ancient Castor fiber individuals. The Western clade (pink) and Eastern clade (blue) have two Holocene contact zones; one in Eastern Europe and one in NW Scandinavia. A now extinct clade existed in the Danube Basin (green) until the late Holocene26. Sampling localities for the British data are indicated with dotted square icons, all other points refer to those generated by Horn et al.26. Only localities from where successful sequences were retrieved are shown. These represented 17 specimens from the SW and SE of England (SI Table 2). Approximate locations of extant relict populations (1 to 8) from where modern C. fiber haplotypes derive are shown in black. Map created using ArcMap v10.5, accessed at www.esri.com.
