Sample collection
The Canada lynx and bobcat analysis was continental, incorporating the entire range of Canada lynx, and the area of range overlap with bobcat at the southern extent of Canada (see Koen et al., 2014). Hide samples (2.5 mm × 2.5 mm) of legally trapped individuals were collected from the North American Fur Auction. Species assignments were initially made by the trappers who harvest the animals, and then confirmed by fur graders at the auction house and our sampling team. In total, we assessed 1,899 Canada lynx samples and 750 bobcat samples, in addition to 2 introgressed lynx and 5 introgressed bobcat samples identified in Koen et al., (2014) (Table 1, Fig. 1). The samples used in this study were a subset of those used in Koen et al., (2014), with the addition of western Canada lynx samples used by Prentice et al., (2017a), and Cape Breton Island lynx samples used by Prentice et al., (2017b).
