Key statistics associated with the gross cost of transport function.

Presented are the 95% confidence intervals of the fixed population parameters of Eq 9, as well as the coefficients of determination (R2) for Eq 9 fitted to each of the three species tested. Statistics obtained using nonlinear mixed-effects regression to accommodate repeated measures of M˙O2 on individuals across velocities [74]. Sample sizes for M. fluviatilis, Hypseleotris and M. adspersa were, respectively: N = 6, 7 and 6.Key statistics associated with the gross cost of transport function.
