Table 1.

Treatment effects on embryo traits. LRTs comparing generalized linear mixed-effects models on (a) fertilization success and (b) embryo mortality, and (c) linear mixed-effects models on hatching time. Models including or lacking the term of interest were compared with the reference model in italics. Significant p-values are highlighted with bold type. Fixed effects: p, pathogen treatment; c, cryopreservation; random effects: m, male; b, breeding block.
