(A) Evolutionary scenarios used in DIYABC. From left to right: 1. sequential colonization northward; 2. mass colonization of northern groves from southern groves; 3. divergence following range reduction during the Pleistocene; and 4. ancient independent colonizations from the eastern Sierra Nevada. All colonization events were followed by a bottleneck shown as thin line. t col1: time of first colonization northward for the sequential scenario and for all northern colonizations for the mass colonization model; t div1: divergence time for scenario 3 Pleistocene divergence; t div2: divergence time for scenario 4 ancient colonization; t anc: time of ancestral change in population size. (B) Output from STRUCTURE (Pritchard et al. 2000) showing individual assignments to clusters. Figure produced using DISTRUCT (Rosenberg 2004).
