Results of the fishery simulations of the assignment units identified using the top ranked 288 SNPs.

<p>A) 100% simulations, B) Mixed Stock Fishery simulation with equal proportions in each assignment unit, C) Mixed Stock Fishery simulation with proportions in each assignment unit based on productivity of that unit. In A and B, horizontal grey lines represent actual simulated proportions and points represent mean simulation proportion estimates. In C, black bars represent simulated proportions and light bars mean simulation proportion estimates. In all plots, bars represent 95% confidence intervals calculated over 1000 replicate simulations.</p

Assignment units as defined by <i>k</i>-means clustering.

<p>A) Results of <i>k</i>-means clustering (insert) showing <i>k</i> = 7 as best cluster number, shown by differently coloured symbols. B) Final assignment units after combining rivers with reciprocal misassignments.</p

Multidimensional plot of pairwise D_A based on all SNPs.

<p>Red points are sites identified as outliers; green points are sites south of the Tweed on the East coast; orange points are Kyle of Sutherland sites (i.e. around sites 12 and 13 on <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0164327#pone.0164327.g001" target="_blank">Fig 1</a>) and blue points represent the remaining Scottish samples.</p
