Analysis of variance (ANOVA)
Statistical method that yields values that can be tested to determine whether a significant relation exists between variables.
Of or relating to zero dissolved-oxygen conditions, unsupportive of aerobic life.
Of or relating to measurement by weight.
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.
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.
Of or relating to the concentration of dissolved oxygen in an organism or environment that is considered functionally normal.
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.
An animal that feeds on fish.
The state or condition of feeding on fish.
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.
