Baseline food preferences.

<p>Food choices of three strepsirrhine species are depicted for (A) all subjects tested and (B) those subjects that showed relatively strong preferences during baseline trials. Presented are the frequencies (mean ± standard error of mean) with which the animals selected red foods (i.e., young leaves or ripe fruits; shaded bars) versus green foods (i.e., mature leaves or unripe fruit; open bars) when both visual and olfactory cues were simultaneously available. Numbers at the bottom of the open bars represent the number of individuals used in the analyses (G-test: * <i>P</i><0.05, *** <i>P</i><0.001).
