Regression coefficients (odds ratios) and 95% confidence limits from top AICc-ranked model returned by multinomial logistic regression of dorsal color on genetic group, latitude, altitude and geology.

Odds ratios are interpreted as the likelihood of being in a particular category in reference to a baseline (e.g., for the model coefficient “geology: alluvial/cone (1/4),” the β estimate represents the probability of being in color category 1 versus 4 given that animal was collected on alluvial soil versus a lava cone). Significant β estimates are indicated by an asterisk.Regression coefficients (odds ratios) and 95% confidence limits from top AICc-ranked model returned by multinomial logistic regression of dorsal color on genetic group, latitude, altitude and geology.
