Ocean acidification affects acid-base physiology and behaviour in a model invertebrate, the California sea hare (<i>Aplysia californica</i>).

ABSTRACT: Behavioural impairment following exposure to ocean acidification-relevant CO₂ levels has been noted in a broad array of taxa. The underlying cause of these disruptions is thought to stem from alterations of ion gradients (HCO3-/Cl-) across neuronal cell membranes that occur as a consequence of maintaining pH homeostasis via the accumulation of HCO3- . While behavioural impacts are widely documented, few studies have measured acid-base parameters in species showing behavioural disruptions. In addition, current studies examining mechanisms lack resolution in targeting specific neural pathways corresponding to a given behaviour. With these considerations in mind, acid-base parameters and behaviour were measured in a model organism used for decades as a research model to study learn
