Figure 1From: Relative role of life-history traits and historical factors in shaping genetic population structure of sardines (Sardina pilchardus)Number of sardine populations with the highest posterior probability expressed as the ΔK, for each of the nine assumed sardine populations (K). ΔK is calculated as the mean of the absolute values of the second derivative of L(K), (L" (K)) average over five runs divided by the standard deviation of L(K) [71].Back to article page
