摘要

Routine biomonitoring of aquatic ecosystems generally is performed with the intent of demonstrating a causal relationship between stressors and responses. However, because it is impossible to eliminate other potential explanations for observed spatio- temporal correlation between stressors and responses, demonstrating causal relationships is highly tenuous in descriptive studies. In this research we show how results of descriptive and experimental approaches can be integrated to demonstrate a causal relationship Between heavy metals and benthic community responses in a Rocky Mountain stream(CO, USA). By using a stressor identification Process, we show that effects and exposure data collected from a contaminated site (CO, USA) can be integrated With experimental data to support causal arguments.
