1. Sample locations and morphological analysis. (A) Map of Scotland
showing the sampling locations. (B) Pictures showing an example ecomorph
pair, here from Loch Tay. Principal component analysis for landmark
analysis for Head shape (C) and Body shape (D). Individuals are coloured
by lake with larger points representing the mean values for each
ecomorph with a line connecting means in each pair. Vector plots display
how head shape (E) and body shape (F) morphology changes across PC1 with
diagrams showing where each landmark was placed on the fish for each
phenotype. Grey points show landmark positions at the minimum PC1 score
and vectors show how landmark positions changes at the maximum PC1
score.
