  1. The Step length 1–7 covariates report the coefficient values from the elevation-adjusted step length spline. Standard errors reflect Forester et al. [83]’s adjustment for serial autocorrelation. Values in bold indicate that the coefficient’s 95% confidence interval does not overlap zero. Overlap patterns were identical for 85% confidence intervals (cf. Arnold [96] for use of wider confidence intervals with information theoretic model selection)
