Fig. 8. Correlation between residual contrasts in maximum running speed (MRS) and habitat type for non-fossorial rodents and marsupials. Habitat type was scored according to Garland et al. (Garland et al., 1988): 3=open country, e.g. deserts; 2=terrestrial, but habitat less open than in 3; 1=intermediate between terrestrial and arboreal; 0=arboreal.
