Fig. 1. Summary of studies of the relationship between limb length and various locomotor performance categories in terrestrial vertebrates. The year of each study is shown in parentheses. Studies shown in bold represent reports of significant relationships between limb length and designated locomotor performance; those shown in regular font did not find significant relationships. Studies designated with an asterisk used lizards as the model species. The animals used in the remaining studies (salamanders, large ungulates, frogs and cats) are indicated by silhouettes. Note that the majority of the investigations of the limb-length—jump performance relationship have used frogs as subjects, and that the current study is the only one to use an endothermic system.
