Resumen:
Diarrhetic Shellfish Poisoning (DSP) is a globally significant human health syndrome mostcommonly caused by dinoflagellates within the genus Dinophysis. While blooms of harmfulalgae have frequently been linked to excessive nutrient loading, Dinophysis is a mixotrophicalga whose growth is typically associated with prey availability. Consequently, field studiesof Dinophysis and nutrients have been rare. Here, the temporal dynamics of Dinophysisacuminata blooms, DSP toxins, and nutrients (nitrate, ammonium, phosphate, silicate, organiccompounds) were examined over four years within two New York estuaries (MeetinghouseCreek and Northport Bay). Further, changes in the abundance and toxicity of D.acuminata were assessed during a series of nutrient amendment experiments performedover a three year period. During the study, Dinophysis acuminata blooms exceeding onemillion cells L-1 were observed in both estuaries. Highly significant (p
