Appendix B (TABLE B1). Pearson and Spearman correlation coefficients, two-tailed p values, and power analysis (Fisher Z, based off of Pearson’s correlations) for the correlation between raw sprint speed and log10 Ucrit (raw), residual sprint speed and residual log10 Ucrit (residual), and relative sprint speed and Ucrit (bl/s). Significant correlations in bold. Residuals were obtained from the ANCOVA model with site, sex, river and site × sex interaction as a fixed effects, and standard length as a covariate.
