Impact of ocean acidification (ΔpH 0.5) and warming (+4°C) on routine metabolic rate (µmol O₂ h⁻¹ embryo) of (a) early stage embryos, (b) intermediate stage embryos and (c) pre-hatching embryos of bamboo shark (Chiloscyllium punctatum). n = 5 per stage. Values represent mean ± s.d. Different upper- and lower-case letters represent statistical differences between pH treatments at 26°C and 30°C, respectively (p < 0.05). Asterisks represent significant differences between temperature treatments at the same pH condition. For more statistical details, see electronic supplementary material, table S3.
