Lethal temperatures (°C; M ± SD) of the investigated species for the hypoxia, normoxia and hyperoxia treatment. Different letters indicate significant differences among oxygen treatments (small letters: ANOVA with Scheffé post hoc tests; capital letters: Mann–Whitney U‐test with Bonferroni correction)
