Extended Data Fig. 2: Principle component analyses of z-score standardized log transformed relative fitness values across fitness components.
From: Experimental evolution of adaptive divergence under varying degrees of gene flow

Each point represents one population or subpopulation subjected to the top (blue) or bottom (red) selection regime. Eigenvectors are indicated by arrows for each fitness component. Arrows pointing in the same direction reflect a positive relationship between components, arrows in opposite direction indicate a negative correlation or trade-off and orthogonal arrows suggest no relationship. The relative contribution to variance in PC1 and PC2 is symbolized by length of the arrow. Proportion of variance explained by each PC is shown in parenthesis for both axes. Results are shown for the α and β genetic background. Abbreviations of migration treatments as in the main manuscript.
