Effects of sex, body size and body mass on colouration of 175 common lizards caught in natural populations.

The results from an ANCOVA analysis are shown with: hue, chroma and brightness as dependent variables; sex as a fixed factor; population as a random factor; and SVL, tail length and body mass as covariates. The final model was determined using backward elimination and is shown in bold. Test statistics of backward eliminated variables are given before backward elimination.
