摘要

This research integrates field biomonitoring and laboratory experiments to testthe hypothesis that benthic communities collected from different locations vary in their sensitivity to metals. Community-level responses of benthic invertebrates and perihyton collected from 2nd-5th order streams were examined in stream microcosms. Responses of benthic communities in experimental streams will be compared to responses observed in Rocky Mountain streams impacted by heavy metals. The specific objectives of this research were; (1) to test the hypothesis that responses of benthic communities to heavy metals measured in experimental streams can be employed to predict responses of these communities in the field; and (2) to test the hypothesis that structural and functional responses of benthic communities to metals varies along longitudinal stream gradients.
