Toxin content of Alexandrium catenella in response of nitrogen sources, algal alarm cues, and grazer exposure
Abstract:
Data include Paralytic Shellfish Toxin production of the marine dinoflagellate Alexandrium catenella. PST production of A. catenella was measured as a function of varying concentrations of added nitrogen sources
(ammonium and urea), alarm cues from lysed conspecific (A. catenella Group I strains) and interspecific (the diatom, Thalassiosira weissflogii, and the green flagellate, Tetraselmis sp.) algae, and the presence of a grazer (the copepod Acartia hudsonica).
Independent variable: treatment type such as nitrogen sources (mol per liter), algal alarm cues (carbon content per cell), and grazer exposure in either the F/2 or FSW assays (control)
Dependent variables: cell density (cells per liter), cell toxin content (mol per cell), cell diameter (μm per cell)
