Figure 1 . (A) Samples of Canada lynx (Lynx canadensis , black and grey circles), bobcat (Lynx rufus , red circles), amplified at 14 neutral microsatellites and the NR1D1 cTNR locus. Coordinates for lynx samples represent the centroid of sampling units (defined in methods). Samples of Canada lynx subdivided into “eastern” (black circles) and “western” (grey circles) lynx groups for RDA analyses. Coordinates of bobcat samples represent centroids of counties (USA), traplines (Canada), or province/state when finer resolution spatial information was not available. (B) Map of introgressed Canada lynx (Lynx canadensis ) and bobcat (Lynx rufus ) identified in Koen et al. (2014), and putative introgressed lynx identified via mixed genotypes at the NR1D1 locus (current study). Samples from Saskatchewan, Alberta and Texas are plotted as the centroid of province/state. All other samples are plotted as centroids of traplines (Canada) or counties (USA) where the individual was trapped. Ranges of lynx and bobcat are represented by the solid grey and hatched grey areas, respectively. Online version in colour.
