Toward a Mechanistic Understanding of Marine Invertebrate Behavior at Elevated CO2

Elevated carbon dioxide (CO2) levels can alter ecologically important behaviours in a range of marine invertebrate taxa; however, a clear mechanistic understanding of these behavioural changes is lacking. The majority of mechanistic research on the behavioural effects of elevated CO2 has been done in fish, focusing on disrupted functioning of the GABAA receptor (a ligand-gated ion channel, LGIC). Yet, elevated CO2 could induce behavioural...
