## distribution

the occurrence of a species over the total area in which it occurs, i.e. its range or geographical distribution. In aquatic organisms or soil organisms, or even organisms living on mountains, vertical distribution is also important. In some organisms vertical distribution may vary seasonally, as does geographical distribution, particularly in migratory forms. See also FREQUENCY DISTRIBUTION, DISPERSION.
