This study examined the consequences of ocean climate change on the production of bioactive molecules and the lipid composition of Dicathais orbita. Exposure to elevated temperature and CO2 levels resulted in lower concentrations of the muscle relaxing choline ester murexine and the brominated indole tyrindoxyl sulphate, but higher amounts of 6-bromoisatin. The total yield of extract was not affected by elevated temperature or pCO2 treatments, but the composition of fatty acids was impacted, with a reduction in healthy polyunsaturated fatty acids under these conditions. This has potentially important implications for the production of marine secondary metabolites and the viability of the species under future climate.
