Effects of ocean acidification on embryonic respiration and development of a temperate wrasse living along a natural CO2 gradient
Volcanic CO2 seeps provide opportunities to investigate the effects of ocean acidification on organisms in the wild. To understand the influence of increasing CO2 concentrations on the metabolic rate (oxygen consumption) and the development of ocellated wrasse early life stages, we ran two field exp...
