Elevated pCO₂ Affects Feeding Behavior and Acute Physiological Response of the Brown Crab Cancer pagurus.

ABSTRACT: Anthropogenic climate change exposes marine organisms to CO₂ induced ocean acidification (OA). Marine animals may make physiological and behavioral adaptations to cope with OA. Elevated pCO₂ may affect metabolism, feeding, and energy partition of marine crabs, and thereby affect their predator-prey dynamics with mussels. Therefore, we examined the effects of simulated future elevated pCO₂ on feeding behavior and energy metabolism of the brown crab Cancer pagurus. Following 54 days of pre-acclimation to control CO₂ levels (360 μatm) at 11°C, crabs were exposed to consecutively increased oceanic CO₂ levels (2 weeks for 1200 and 2300 μatm, respectively) and subsequently returned to control CO₂ level (390 μatm) for 2 week
