Abstract: This paper emphasizes the integration of ecology and ecotoxicology. The main objective is to present the development of an early warning tool for environmental risk assessment. First, a reference ecological network of a plankton community was built from in situ flow cytometry data. Next, a set of fuzzy ecotoxicological rules to explain impacts from three pollutants were constructed from the scientific literature and expert knowledge. These rules were applied to the plankton network to simulate disturbance and produce an impacted network. Network indices were used to assess the consequences of this simulated disturbance, and a regime shift in the planktonic system was noted. Coastal zone ecosystem managers could use this type of model to anticipate early warnings in disturbance scenarios, allowing estimates of possible impacts to the marine ecosystem.
