Opis

The authors give an overview of the current process of ecological risk assessment for toxic chemicals and of how modeling of populations, ec osystems, and landscapes could improve the status quo. They present a classification of ecological models and explain the differences betwee n population, ecosystem, landscape, and toxicity-extrapolation models. The authors describe the model evaluation process and define evaluati on criteria. Finally, the results of the model evaluations are present ed in a concise format with recommendations on modeling approaches to use now and develop further.
