  1. Values were extracted from linear mixed models on the respective parameters, corrected for saliva cortisol concentrations and litter size, with age and individual ID within mother as random effects.
  2. aBack-transformed values from second and third root transformations.
  3. Male body mass model 1 corresponds to calculations of male-specific body mass based on a reduced dataset.
  4. Male body mass model 2 corresponds to calculations of male-specific body mass based on a reduced dataset, additionally corrected for testes development.
