Table 1. Results of regression analyses for running/walking placental mammals.
The regression expressions are: Log(dependent variable) = slope × log(independent variable) + intercept. AVG means the cohort averaging regression method. PI(n) means the phylogenetic informed regression method using BayesTraits and the number in parentheses is the estimated value of lambda.
| Order or family | Regression type | Independent variable | Dependent variable | Slope | Intercept | R 2 | Number samples |
|---|---|---|---|---|---|---|---|
| Artiodactyla + Carnivora | AVG | Height (m) | Mass (g) | 2.6112 | 5.0584 | 0.9932 | NA |
| PI(0.89 | Height(m) | Mass (g) | 2.4893 | 5.076 | 0.8435 | 172 | |
| All | AVG | Height (m) | Mass (g) | 2.8711 | 5.1677 | 0.9886 | NA |
| PI(0.92) | Height (m) | Mass (g) | 2.4875 | 5.2517 | 0.8424 | 189 | |
| Ruminant Artiodactyla | PI(0.0) | Mass (g) | BMR (watts) | 0.7805 | −1.8058 | 0.9742 | 19 |
| Carnivora | PI(0.87) | Mass (g) | BMR (watts) | 0.7579 | −1.8826 | 0.909 | 59 |
| Carnivora less Mustelidae | PI(0.61) | Mass(g) | BMR (watts) | 0.758 | −1.8937 | 0.9053 | 46 |
| Mustelidae less Enhydra | PI(1.0) | Mass (g) | BMR (watts) | 0.6852 | −1.4688 | 0.9653 | 12 |
| Perissodactyla | PI(1.0) | Height (m) | Mass (g) | 1.784 | 5.4961 | 0.8046 | 14 |
Notes.
“All” in the Order or Family column means the combination of Artiodactyla, Carnivora, Perissodactyla and Proboscidea. Height (m) is shoulder height in meters. Mass (g) is body mass in grams. BMR (watts) is basal metabolic rate in watts. NA means Not Applicable.
