Figure 2

Observed and simulated values of the Garza-Williamson index for (a) Mullus barbatus and (b) Mullus surmuletus populations. The observed M-ratio values are displayed in black solid line. The simulated critical M threshold (Mc) values below which a bottleneck is evident, was calculated for different ancestral theta and displayed by grey dot (θ = 0.5), dash (θ = 1) and long dash (θ = 10) lines. Populations M-ratio and the Mc parameters were calculated using M-P-Val and Critical_M39.
