SETAC/AFOSR New Investigator Program.

Abstract

Microbial communities were collected on artificial substrates from Spring Creek and Douglas Lake at different times of the year. Communities were exposed to copper under continuous flow conditions using the artificial substrates - microcosm procedure of Pratt and Bowers (1990). Several endpoints were monitored and included both structural and functional measures. MATC's (maximum allowable toxicant concentrations) were calculated based on significant responses and community sensitivity during different seasons within the same ecosystem and between different ecosystems. Based on these results, the biotic factors which are important in influencing community response to toxic impacts were determined.
