Ocean warming and acidification alter the behavioral response to flow of the sea urchin Paracentrotus lividus.

ABSTRACT: Ocean warming (OW) and acidification (OA) are intensively investigated as they pose major threats to marine organism. However, little effort is dedicated to another collateral climate change stressor, the increased frequency, and intensity of storm events, here referred to as intensified hydrodynamics. A 2-month experiment was performed to identify how OW and OA (temperature: 21°C; pH_T: 7.7, 7.4; control: 17°C-pH_T7.9) affect the resistance to hydrodynamics in the sea urchin Paracentrotus lividus using an integrative approach that includes physiology, biomechanics, and behavior. Biomechanics was studied under both no-flow condition at the tube foot (TF) scale and flow condition at the individual scale. For the former, TF disk adhesive properties (attachment stre
