Table 3 Second experiment: Linear mixed model on embryo hatching time, hatchling length, larval length, and yolk sac volume at 130 dpf when predicted by treatment (exposure to Aeromonas salmonicida) and paternal skin coloration (yellowness) and/or parental kinship.

From: Parental kinship coefficient but not paternal coloration predicts early offspring growth in lake char

  1. Hatching time was included as a further covariate when testing for effects on hatchling length. The table gives the parameters as in Table 1. Family identity and the interaction between family ID and treatment were included as random factors. Significant p-values are highlighted in bold.
  2. aREML unbounded variance components ± standard error, Wald p-values.
