| GarlandJanis.Original {PHYLOGR} | R Documentation |
This data set was used by Garland & Janis in their analysis of metatarsal/femur ration and running speed in cursorial mammals. The data refer to several ecomorphological characteristics for a set of 49 mammals (18 carnivores and 29 ungulates).
This data frame contains the following columns:
Carnivore or HerbivoreGarland, T. Jr., and Janis, C. M. (1993). Does metatarsal/femur ratio predict maximal running speed in cursorial mammals? J. Zoology, London, 229, 133–151.
