Fig 3. Observed and PEM (Phylogenetic eigenvector map) predicted values of generation length in the wild (GLw) obtained following leave-one-out cross-validation—for 54 species (excluding 32 species with missing data).

The dashed line is a 1:1 line, the solid black line is a regression line of observed values as a function of predictions, and the grey envelope represents the 95% confidence limits of the regression line. Horizontal bars are limits of the 95% confidence intervals.
