Description:
The treatment that the orgnaisms were evaluated in, and where traits were measured and fitness was estimated. 1 = ambient (AM): temperature = 18 ?C, pCO2 = 400 uatm. 2 = ocean acidification (OA): temperature = 18 ?C, pCO2= 2000 uatm. 3 = ocean warming (OW): temperature = 22 ?C, pCO2 = 400 uatm. 4 = ocean warming and acidification (OWA): temperature = 22 ?C, pCO2 = 2,000 uatm.
