RMR in μgO2 h−1 per embryo per treatment at the A) eyed stage (control n = 18, late hypoxia, late warm, late warm hypoxia and chronic warm hypoxia [n = 17], early hypoxia and early warm [n = 16], chronic warm [n = 15] and early warm hypoxia [n = 14]) and B) silver-eyed stage (n = 18 per treatment except late hypoxia, late warm and chronic warm hypoxia [n = 17] and control and early hypoxia [n = 16]). Boxplots of the data represent the median as the centre line, IQR as the box, values 1.5 times the IQR as the whiskers and values greater than 1.5 times the IQR as black points. Diamonds indicate the mean value. Boxplot fill colours represent the developmental treatment: control (green, 100% DO, 10°C), hypoxia (blue, 50% DO, 10°C), warm (red, 100% DO, 14°C) or warm hypoxia (purple, 50% DO, 14°C). The three boxplots for each stressor type represent the developmental timing of exposure as early (eyed stage, light colour shade), late (silver-eyed stage, medium colour shade) and chronic (fertilization through hatching, dark colour shade).
