Figure 6. Effects of the experimental treatment on mass excreted by nestlings according to nestling rank calculated from RM-ANOVAs in the experimental sessions where the interaction effects between treatment and nestling rank resulted significant (or almost).
The significance values of interactions between experimental treatment and nestling rank are also shown. P-values associated to LSD post hoc (i.e. treatment effect within nestling rank) tests are indicated as ns: P>0.05; st: 0.1≤P≥0.05; *: P<0.05; **: P<0.001 and ***: P<0.0001.
