Kinetic impact dynamic parameters.

Shown: scaling exponent (from LMM analysis), exponent standard error, p value determining if the slope of the data is significantly different from zero, p value determining if the slope of the data is significantly different from the isometric prediction, scaling analysis conclusion, scaling trend (if conclusion is not significantly different from isometry), intercept, t statistic (observed slope vs. slope predicted by isometry), degrees of freedom, number of species, number of individuals and number of impacts (i.e. instances of foot impact analysed) per impact variable. The exponent b is for the equation: log y = b log(Mb)+log(a); where b is the slope (exponent); a is the elevation (y-intercept); and y is the impact parameter of interest. Asterisks denote an exponent that is significantly different from isometry.
