Glossary
- Analysis of variance (ANOVA)
- Statistical method that yields values that can be tested to determine whether a significant relation exists between variables.
- Anoxic
- Of or relating to zero dissolved-oxygen conditions, unsupportive of aerobic life.
- Gravimetric
- Of or relating to measurement by weight.
- Hypoxic
- Pertaining to, in aquatic environments, conditions in which there is a dissolved-oxygen concentration of less than 3mg per liter* of water; such conditions are usually harmful or deadly to aerobic life.
- Microbenthos
- Organisms (e.g., protozoa, nematodes) too small to be seen with the naked eye that live on or in sea or lake bottoms.
- Mitigation banking
- The process of preserving, enhancing, restoring, or creating habitat to compensate for (current or future) habitat disturbances elsewhere, especially due to development.
- Normoxic
- Of or relating to the concentration of dissolved oxygen in an organism or environment that is considered functionally normal.
- Oligohaline
- Of or relating to a body of water with a salinity measure of less than 5 parts per thousand (or 5 grams of salt per liter).
- p < 0.01
- An indicator of statistical significance in which the probability of the result of a study being a chance occurrence is less than 1 in 100.
- Piscivore
- An animal that feeds on fish.
- Piscivory
- The state or condition of feeding on fish.
- Polyhaline
- Of or relating to a body of water with a salinity measure between 18 and 30 parts per thousand (or grams of salt per liter).
- Student-Newman-Keuls multiple comparison test
- A statistical method for determining differences among groups of samples.
