Are control of extracellular acid-base balance and regulation of skeleton genes linked to resistance to ocean acidification in adult sea urchins?

Highlights

• Arbacia lixula and Paracentrotus lividus were differently affected by low pH exposure.

• P. lividus skeleton integrity was not affected by low pH.

• Arbacia lixula exposed to low pH near CO2 vent showed decreased skeletal integrity.

• pH exposure leads to changes in biomineralization-related genes expression.

• Acid-base regulation capacity is linked with a better tolerance to low pH.
