Applying the Reference Condition Approach to bioassessment of Cape Breton Island streams
The reference condition approach (RCA) to bioassessment assesses the effect of human activity on ecosystems relative to sites that are relatively unexposed to such activity. This study uses the RCA to characterize the nature of relatively pristine streams on Cape Breton Island, Nova Scotia as a …

Using impact simulations to evaluate the power of Skeena Reference Condition Approach stream bioassessments
… This study evaluated the performance of Skeena Reference Condition Approach (RCA) bioassessments by calculating Type I and Type II error rates and power using a data set of artificially-impacted test sites. Results from this study demonstrated that there are trade-offs between the two error …

Multimetric assessment of freshwater macroinvertebrate communities in Flanders, Belgium
… relative proportion of the index compared to the reference conditions. This EQR ranges from zero to one, respectively corresponding to a bad and a very good ecological status. This interval is divided into five classes reflecting bad, poor, moderate, good and high ecological status (EU, 2000). For …
