  1. Model selection results of comparison between nine models describing the variability in the observed and expected oxygen consumption (ml  g− 1 min− 1) change between post-and pre-experimental days for juvenile and adult Meriones crassus. Values are weights (w i) in percentages of Akaike information criterion corrected for sample size—the relative likelihood of the current model, given the data and the set of models. The set of models includes the null model (#1), the pure flea effect model (#2), the data source (DS; observed or expected, #3) and the additive or multiplicative effects with age (juveniles versus adults), treatment (control versus flea-infested rodents), and the time of the day (light versus dark hours). In all models that include interaction terms, the lower order interactions were included although not shown. The best models supported by the data (wi > 20 %) are marked in bold and were used for stage 2
