The MBI Glossary
Need help with technical terminology? Our glossary provides clear definitions of key terms used in freshwater science and environmental research.
Use Subclasses
A subcategorization of use classes into discrete and meaningful descriptions. For aquatic life this would include a hierarchy of warmwater and cold water uses and additional stratification provided by different levels of warmwater uses and further stratification by waterbody types.
DELT Anomalies
The percentage of Deformities, Erosions (e.g., fins, barbels), Lesions and Tumors on fish assemblages (DELT). An important fish assemblage attribute that is a commonly employed metric in fish IBIs.
Biological Monitoring
The use of a biological entity (taxon, species, assemblage) as a detector and its response to change as a measure of response in determining environmental conditions. Ambient biological surveys and toxicity tests are common biological monitoring methods; also known as "biomonitoring".
Technical Reports
