Impacts of ocean acidification on sea urchin growth across the juvenile to mature adult life-stage transition is mitigated by warming.

ABSTRACT: Understanding how growth trajectories of calcifying invertebrates are affected by changing climate requires acclimation experiments that follow development across life-history transitions. In a long-term acclimation study, the effects of increased acidification and temperature on survival and growth of the tropical sea urchin Tripneustes gratilla from the early juvenile (5 mm test diameter-TD) through the developmental transition to the mature adult (60 mm TD) were investigated. Juveniles were reared in a combination of three temperature and three pH/pCO₂ treatments, including treatments commensurate with global change projections. Elevated temperature and pCO₂/pH both affected growth, but there was no interaction between these factors. The urchin
