This volume assesses where we are today in the fields of ecology and toxicology and which tools will be helpful in designing tomorrow's studies. It is divided into three sections: impact of multiple stresses on ecosystems, establishing the health of ecosystems, and future methods in ecotoxicology.

This volume pulls together information from appropriate experts and the resulting literature of an international conference sponsored by the University of California Toxic Substances Program, to assess where we are today in these relevant fields and which tools will be helpful in designing tomorrow's studies.
