VARIABILITY IN REPLICATE BENTHIC MACROINVERTEBRATE SAMPLES
Benthic macroinvertebrates are the most widespread tool for assessing the biological quality of freshwater and have been used for decades in environmental assessment. Although benthic macroinvertebrates have been used for a long time, the study of variability between replicate samples has not been assessed. Matched-paired replicate Hess samples were collected within a specific habitat and time of year from the San Miguel River in Colorado, Red River in New Mexico, and multiple stream locations in West Virginia. Replicate samples were analyzed for the overall effects of sampling variation for a range of commonly used metrics.
