Kendall’s τ correlation coefficients between body condition indices (BCIs) and percent fat, scaled fat, residual fat, and snout-vent length (SVL).

A desirable BCI is strongly correlated with ‘true’ body condition (i.e., percent fat, scaled fat, or residual fat) but is not correlated with size (i.e., SVL). Values with the greatest correlation coefficient for each column are italicized. Generally speaking, BCIs that are strongly correlated with percent fat are also strongly correlated with SVL in our dataset. Abbreviations for each of the BCIs are provided in Table 1.
