Penotypic trait correlations. Visualisation of Spearman's rank correlations between traits. Non-significant correlations and those < 0.5 are not shown. Line width and colour represent correlation values between traits. All correlations below 0.7 are in grey, > 0.7 in green, > 0.8 in blue and > 0.9 in red. Line widths are increased from 0.6 to 0.9 in 0.1 increments for emphasis. Thick red lines show the strongest correations between traits.
