The blooms of the toxic dinoflagellate Karenia selliformis can be predicted with accuracy derived from knowledge of the main forcing variables. A naive Bayes classifier modeling framework, a member of the Bayesian network family, is used to identify

Distribution and abundance of potentially harmful dinoflagellates were assessed in three matrices in relation with heavy metals concentrations in the Gulf of Gabes. Tidal Flat Waters (TFW), sediments and macroalgae (Ulva rigida) were collected from f
