Sex-specific tolerance of temperature and salinity. ANOVA was used to test effects of cohort, sex, and cohort x sex interaction, with family as a random effect. For significant interactions, significant post hoc sex differences within cohorts are shown. (***p < 0.001, **p < 0.01, *p < 0.05, nsnot significant). (A) Proportion survival after 2 h exposure to high temperature (38 °C). (B) Proportion swimming after 10 min exposure to hypersalinity (75 PSU). (C) Proportion swimming after 10 min exposure to hyposalinity (5 PSU).
