FIGURE 2.

Distribution of caribou and reindeer Rangifer tarandus sampled herds across the Holarctic distribution of the species. Sampling locations are colored according to population membership of each herd to the North American clade, considering two genetic clusters (from blue for North American clade to red for Euro‐Beringian clade) as inferred in Yannic, Pellissier, Ortego, et al. (2014). For more details on sampling locations, see Yannic, Pellissier, Ortego, et al. (2014); Yannic et al., 2018)
