Fig 4. Observed and binning approach 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).

Predictions are presented when incorporating bins of log₁₀ body-mass (A) and irrespective of body-mass (B). The dashed lines are 1:1 lines, the solid black lines are regression lines of the observed values as a function of predictions and the grey envelopes represent the 95% confidence limits of the regression lines.
