Figure 1
Comparisons among demographic, genetic and demo-genetic extinction times. In all three panels, each circle represents the median extinction time computed from 250 trajectories for a given ecological scenario. Dotted lines are the bissectrices. (1a) Demographic versus genetic median extinction times. The size of symbols is proportional to overall metapopulation size (Kt); lighter colors indicates higher levels of fragmentation (black: N < 5; dark grey: 5 ≤ N ≤ 10; light grey: N > 10). (1b) Demographic versus demo-genetic median extinction times. The size of symbols is related to the regime of perturbations (large (small) symbols = high (low) frequency of perturbations). The color of symbols indicates the basic fecundity rate (grey: F = 1.5; black: F = 1.1). (1c) Genetic versus demo-genetic median extinction times. The size of symbols is proportional to overall metapopulation size (Kt); lighter colors indicates higher levels of fragmentation (black: N < 5; dark grey: 5 ≤ N ≤ 10; light grey: N > 10).
