Fig 1.
Temporal development of (A) mean pCO2 and (B) mean dissolved inorganic carbon of each treatment. Error bars denote ± 1 SE (n = 3). Open symbols represent high pCO2 (1400 μatm) and closes symbols low pCO2 (560 μatm) concentrations. Symbols for the treatment combinations as in key.
Fig 2.
Mean abundance of nauplii, copepodites and adults of the last experimental day.
Error bars denote ± 1 SE (n = 3). Open symbols represent high pCO2 (1400 μatm) and closes symbols low pCO2 (560 μatm) concentrations. Symbols for the treatment combinations as in key.
Fig 3.
The nature (synergistic, additive, antagonistic) and magnitude of the observed interactions of temperature and OA on copepods.
Error bars denote ± 1 SE (n = 3).
