The number or amount of something.
(Ecol). Refers to the total number of a particular species in an area. See Frequency
Information obtained from samples or observations and used as a measure of the weight or number of fish which make up a stock.
number of organisms per unit of habitat space.
(physics) the ratio of the number of atoms of a specific isotope of an element to the total number of isotopes present
Weight or number of fish which make up a stock or species.
number of individuals in a sample area.
the total number of individuals of a species present in an area. Also see, Relative Abundance.
The number of individuals in a stock or a population.
Number of individuals in a particular area
The degree and frequency of a species population, often indicative of the success it is experiencing in the wild.
Relative number of atoms of a particular element, or isotope of an element, in the chemical composition of a single substance or object.
The relative volume among all spots representing a particular protein in a BVA data set. The weakest spot is taken as 1.00 and the others are displayed relative to this.
The total number of sub-taxa within a taxon. For example, we will commonly look at the total abundance of creatures within a genotype, or the abundance of genotypes within a species.
the number or density of individuals in a population
the prevalence of a particular RNA, or class of RNA molecules, in the cell. The relative amounts of a particular messenger RNA (mRNA) species in different samples is frequently expressed in terms of relative abundance.
The number of abalone counted or estimated. See relative and absolute abundance.
See relative abundance and absolute abundance.
number, or amount, of organisms that you can count.
Estimated number of juveniles outmigrating from a stream.
the size of a salmonid population or of a component of the population expressed as numbers of fish.
The number of individual organisms in an area
Abundance is an ecological concept referring to the relative representation of a species in a particular ecosystem. It is usually measured as the mean number of individuals found per sample.
