""Premise 5: Changing waters and a changing society call for better assessment""""Premise 6: Biological monitoring detects biological changes caused by humans""; ""Premise 7: Ecological risk assessment and risk management depend on biological monitoring""; ""Section III: Multimetric Indexes Convey Biological Information""; ""Premise 8: Understanding biological""; ""Premise 9: Only a few biological attributes provide reliable signals about biological condition""; ""Premise 10: Graphs reveal biological responses to human influence""

""Premise 11: Similar biological attributes are reliable indicators in diverse circumstances""""Premise 12: Tracking complex systems requires a measure that integrates multiple factors""; ""Premise 13: Multimetric biological indexes incorporate levels from individuals to landscapes""; ""Premise 14: Metrics are selected to yield relevant biological information at reasonable cost""; ""Premise 15: Multimetric indexes are built from proven metrics and a scoring system""; ""Premise 16: The statistical properties of multimetric indexes are known""

""Premise 17: Multimetric indexes reflect biological responses to human activities""""Premise 18: How biology and statistics are used is more important than taxon""; ""Premise 19: Sampling protocols are well defined for fishes and invertebrates""; ""Premise 20: The precision of sampling protocols can be estimated by evaluating the components of variance""; ""Premise 21: Multimetric indexes are biologically meaningful""; ""Premise 22: Multimetric protocols can work in environments other than streams""; ""Section IV: For a Robust Multimetric Index, Avoid Common Pitfalls""

""Premise 23: Properly classifying sites is key""""Premise 24: Avoid focusing primarily on species""; ""Premise 25: Measuring the wrong things sidetracks biological monitoring""; ""Premise 26: Field work is more valuable than geographic information systems""; ""Premise 27: Sampling everything is not the goal""; ""Premise 28: Putting probability-based sampling before defining metrics is a mistake""; ""Premise 29: Counting 100-individual subsamples yields too few date for multimetric assessment""; ""Premise 30: Avoid thinking in regulatory dichotomies""

""Premise 31: Reference condition must be defined properly""
