Summary of results from the ANOVA.

Explaining (a) total plasma carotenoid concentration (µg/mL) in Andean condors according to status (wild or captive), age (juveniles, subadults and adults) and sex. (b) Models explaining variation in the plasma concentration of each carotenoid type according to age (pooling juveniles and subadults) and sex of wild Andean condors. (c) Models explaining variation in factor scores of the main carotenoid axis from a factor analysis according to age and sex of wild Andean condors. The estimated effect and standard error as well as F-values, associated probabilities and Partial Eta squared (η2p) are shown for those variables that significantly improved the fit of the models (final model). For those terms that were excluded from the model during the backwards procedure, F-values, P-values and η2p when added to the final model are given. Estimates refer to juveniles and subadults (pooled) and male wild Andean condors in models b and c.
