Figure 4
Graphical representation of comparisons between observed test statistics and the 95% quantile of simulated test statistics. Demographic scenarios were simulated with bottlenecks of variable age and strength and with low (μ = 10-9) and high (μ = 10-8) mutation rates. For all plots, y-axis: effective population size during the bottleneck, expressed as fraction of current population size; x-axis: approximate number of generations elapsed since the bottleneck. Lower left cells thus correspond to recent and strong bottlenecks, upper right cells to old and shallow bottlenecks. Dark cells correspond to scenarios compatible with the observed statistic (i.e. observed statistic is lower than the simulated 95% upper quantile). Upper half: tests for Tajima are D; lower half: tests for Fu and Li's F*. Left half: tests for CguPIP1.1 population SE; right half: tests for EfaPIP1.1 population NW.
