| Summary: | 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 (HCO3Cl) across neuronal cell membranes that occur as a consequence of maintaining pH homeostasis via the accumulation of HCO3Cl. 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 utilized for decades as a research model to study learning, the California sea hare (Aplysia californica). Aplysia exposed to CO2 elevated hemolymph HCO3Cl, achieving full and partial pH compensation at 1200 and 3000 μatm CO2, respectively. Increased CO2 did not affect self-righting ... : Zlatkin and Heuer 2019 Aplysia data Royal Society Open ScienceThis file contains raw data including individual replicates for behavioral trials and acid-base measurements, in addition to biometric data for each animal (mass). For the tail-withdrawal reflex, this includes the amount of time for the reflex in addition to the percent of the body withdrawn. For the righting reflex, the time to complete the reflex is reported. Acid-base measurement data includes extracellular pH (pHe), bicarbonate, and pCO2 levels. ... |
