Fig 6. Results of the first 300 years of population divergence simulations (scenarios 1, 2, and 3) conducted in RMETASIM.

F_ST versus time (years) is plotted based on the 25 year increment mean values derived from 32 simulation replicates conducted for each population size (as shown in the legend), microsatellite mutation rate, and dispersal combination. Shading represents 95% confidence intervals. Horizontal hatched lines reflect the level of F_ST observed empirically between upstream and downstream populations after fast-growing outliers were removed from the downstream juvenile group.
