Visualization of Mantel tests: genetic distance vs. morphological and ecological variables.

<p>Shown are comparisons of genetic distance (pairwise F_ST) vs. (i) the absolute difference in mean relative warp (RW) score for the first two RWs for body (A, B) and head morphology (C, D); (ii) absolute difference in prey abundance (E); and (iii) the absolute difference in median depth (m) (F). Body RW1 and 2 represent 26% and 17% of the total variation; whereas head RW1 and 2 represent 36% and 23% of the total variation. The remaining visualizations of Mantel tests can be seen in Fig S8.4 in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0162325#pone.0162325.s008" target="_blank">S8 File</a>.</p

Association between morphological clusters and genetically-differentiated clusters of lake trout present in Mistassini Lake.

<p>Morphological clusters are identified by symbol shape and ellipses which represent 67% of that cluster’s variation and genetically-differentiated clusters are identified by symbol colour. (A) RW1 vs. 2 and 1 vs. 3 (55%) of body shape variation. Morphological shifts for RW1 (26%) correspond to the slope of the snout, lower jaw and dorsal and belly curvature; RW2 (17%) correspond to slope of top of cranium and dorsal side, length and depth of caudal peduncle; RW3 (12%) correspond to body depth, eye position and size. (B) RW 1 vs. 2 and 1 vs. 3 (71%) of head shape variation. Morphological shifts for RW1 (36%) correspond to length of head and snout, eye position and length of upper jaw; RW2 (23%) correspond to head depth and bluntness of snout; RW3 (12%) correspond to slope of lower and upper jaw. Inset images are visualizations of the shape at the most extreme end of each relative warp.</p

Morphological variation among individual lake trout and across all genetically-demarcated clusters within Mistassini Lake, Québec.

<p>Coloured circles and numbers represent the genetically-demarcated clusters that individual lake trout were assigned to.</p

Geographic location of Mistassini Lake, Québec, Canada and colour frequency, depth distribution and basin preferences of each one of the genetically-demarcated clusters.

<p>(A) Shown on the map are 24 hr gillnet sets (star) and lake sector (W1–6 and E7–12) divided by dashed lines. (B) Frequency of colours observed in each genetically-demarcated lake trout clusters in Mistassini Lake. (C) Depth distribution of lake trout in each one of the genetically-demarcated clusters. Beanplot shows accurate densities and the red line indicates the median. (D) Basin preferences of lake trout in each one of the genetically-demarcated clusters. Results of a generalized linear model (GLM) that took into account the fishing effort and demonstrates that clusters 1 and 5 were caught in higher numbers in the eastern basin and clusters 3 and 4 were caught in higher numbers in the western.</p

Spatial principal component analysis of lake trout showing the first global structure across Mistassini Lake.

<p>Plotted are the lagged scores in which colours (blue to red) represent the score of an individual genotype; each is positioned by its spatial coordinates. Inset is the barplot for all eigenvalues (A), and the screen plot (B) which illustrates the spatial and variance components of those eigenvalues.</p
