Variation in average daily feeding activity and average diurnality index between tau genotypes. Feeding activity, expressed in presence (in the number of 1-min bins per day per individual) at the feeders (no effect of genotype; ANOVA, F = 1.322, P = 0.25) (A) and the diurnality index D (B) estimates from a linear mixed effect model (LME) fitted with sex as fixed effect and date, individual, and enclosure as random effects (effect of genotype with both sexes combined, χ2 = 94.7, df = 8, P < 0.0001).
