ATTAINING THE GOAL OF MORE “ECO” IN ECOTOXICOLOGY DEPENDS UPON BUILDING CONCEPTUAL BRIDGES BETWEEN OBSERVATION AND EXPERIMENT
Early papers on development of contaminant guidelines suggested data from nature were desirable but were too complex to be useful. However, understanding of geochemistry, bioavailability, species-specific biological effects, ecological implications and models that tie these together has advanced greatly in the last three decades. This paper will review, with examples, lessons learned in applications of these advances. Linking ecology and ecotoxicology depends upon linking experiment and observations of nature. The historic tension between the reductionist and the naturalist is no longer valid given the understanding that each has brought. Mechanistic understanding is necessary to explain observations and can lead to increasingly powerful models of nature. But data from nature, in turn, are also necessary to validate mechanisms and both validate and calibrate models. Time series are an underused but powerful tool for not only asking questions, but themselves become experiments if appropriately conceived. The bridge to more effective environmental policies lies in a superstructure made up of knowledge from interlinked disciplines like geochemistry, biology and ecology and a roadway that is paved with observations and experiments from all.
