marginally significantp = 0.045
There was a marginally significant interaction effect of six6 and food availability on SMR in the full model ( p = 0.045) but this was non-significant in the averaged model (electronic supplementary material, table S5), and none of the pairwise contrasts were significant (the largest effect being: six6 EE-genotype, high food versus low food, t 25.6 = −2.37, p = 0.11).
