1. Mean Pcrit for each species (averaged across individuals within that species), plotted versus log mean mass (mg) of individuals in that species (filled circles, Tenebrionidae; open circles, Scarabaeidae).
Mean Pcrit for each species (averaged across individuals within that species), plotted versus log mean mass (mg) of individuals in that species (filled circles, Tenebrionidae; open circles, Scarabaeidae). Bars indicate standard errors of species means, and data points with no error bars indicate species with no replication. There was no significant effect of body size on Pcrit regardless of whether data were analyzed at the level of order (P>0.5) or family (Tenebrionidae, P>0.5; Scarabaeidae, P>0.5).
