Toxic dinoflagellate blooms of Alexandrium catenella in Chilean fjords: a resilient winner from climate change

Exposure of the toxigenic dinoflagellate Alexandrium catenella to variations in pCO2/pH, comparable to current and near-future levels observed in Southern Chilean fjords, revealed potential functional adaptation mechanisms. Under calculated conditions for pH(total scale) and pCO2 ranging from 7.73–8.66 to 69.7–721.3 ?atm, respectively, the Chilean strain Q09 presented an optimum growth
