Snippet: Because many life history traits are correlated, we performed principal components analyses (PCA) on the life history traits: logged body mass, maximum longevity, number of litters per year and litter size (separately for bats and rodents). The variables were rescaled to have unit variance before analysis in R using the 'prcomp' function (R Core Team 2012), and these principal components were then used in subsequent analyses. See Fig. S6 for PCA .....
