Dynamics of population isolation and contraction, and genetic variation from ancient to contemporary times. The Iberian lynx population is represented by a cylinder projected on the distribution map, that becomes progressively fragmented into subpopulations which contract, become genetically differentiated and eventually go extinct. Maps represent the distribution of microsatellite (left) and mitogenomic variation (right) among ancient (top), historical (middle), and contemporary populations (bottom). Microsatellite pies represent the average coefficient of assignment to each of the clusters identified by STRUCTURE from historical (K = 6) and contemporary (K = 2) data sets (fig. 3 and supplementary fig. S7, Supplementary Material online). Mitogenome pies represent the distribution of mitochondrial genome haplotypes. Haplotypes observed only once are represented in shades of gray. Numbers within pies refer to sample size. See figure 2 and supplementary figure S9, Supplementary Material online, for networks depicting the relationship among haplotypes.
