Figure 5

Box-plot showing the significant difference in fishing pressure (corrected for population census size) on populations with significant (sign, P < 0.05, n = 8) and non-significant (ns, n = 10) genetic variation between the temporal samples (non-parametric Mann–Whitney U-test, P < 0.05). Horizontal line, open rectangle, whiskers, and open circle indicate the median, 25th and 75th quartiles, non-outlier range and an outlier, respectively. Fishing pressure was corrected for population census size by dividing the mean fishing pressure for the two sampling years by the estimated census size class of each population.
