  • Results of reduced major axis regressions of the standardised contrasts of log10-transformed morphometric data against the standardised contrasts of log10-transformed snout-vent length (morphometrics) and of the standardised contrasts of the log10-transformed jumping performance variables against the residual contrasts of the log10-transformed hindlimb length (jumping performance) for a comparative data set of 12 species. Note that the intercept of the regression on the contrast data equals 0 by definition (Garland et al., 1993)

  • * denotes a significant regression at the α=0.05 level
