The transition from the last pelagic larval stage to the first benthic juvenile stage in the complex life cycle of marine invertebrates, such as the American lobster, Homarus americanus, a species of high economic importance, represents a delicate phase in these species development. Under future elevated pCO2 conditions, ocean acidification and other elevated pCO2 events can negatively affect crustaceans. This said their effects on the benthic settlement phase are virtually unknown. This study aimed to identify the cumulative effects of stage IV post-larval exposure to elevated pCO2 levels on the life history and physiology of stage V juvenile lobsters. Post-larval lobsters were exposed to a gradient of current and future pCO2 scenarios that were chosen based on current global ocean conditions (400 μatm) to predicted pCO2 values between now and the end of the century (600, 800, 1000 μatm, IPCC 2014), ecologically relevant coastal pCO2 fluctuations (1200 μatm), and levels potentially achieved from industrial ... : Supplement to: Menu-Courey, Kayla; Noisette, Fanny; Piedalue, Sarah; Daoud, Dounia; Blair, Tammy; Blier, Pierre U; Azetsu-Scott, Kumiko; Calosi, Piero (2018): Energy metabolism and survival of the juvenile recruits of the American lobster (Homarus americanus) exposed to a gradient of elevated seawater pCO2.
