Fig. 2: Distribution of mean body mass differences between the sexes in mammals.
From: New estimates indicate that males are not larger than females in most mammal species
Mean mass differences are displayed relative to male body mass for all data included in analyses, color-coded by order. A proportional mass difference of −0.2, for example, indicates that females are 20% larger than males on average. Error bars indicate 95% confidence intervals, data density distributions are scaled such that the area under the curve is the same for each order, and the phylogeny on the left is derived from Upham et al. 87. Please see Supplementary Table 1 for the number of species sampled for each order and family, as well as the full datasheet on Dryad for the number of individuals sampled for each species.
