Range (biology)

Probability distribution

In probability theory and statistics, a probability distribution identifies either the probability of each value of an unidentified random variable , or the probability of the value falling within a particular interval ....

Statistical population

In statistics, a statistical population is a Set of entities concerning which statistical inferences are to be drawn, often based on a random sample taken from the population....
.

In biology, the range or distribution of a species is the geographical area within which that species can be found. Within that range, dispersion is variation in local density.

The term is often qualified:

There are at least five types of distribution patterns:

-scattered/random (Random placement)

-clustered/grouped (The majority are placed in one area)

-linear (Their placements form a line)

-radial (Placements form a ' x ' shape)

-Regular/ordered (They're not random at all, but follow a set placement.

In biology, the range or distribution of a species is the geographical area within which that species can be found. Within that range, dispersion is variation in local density.

The term is often qualified:

sometimes a distinction is made between a species' native range and the places to which it has been introduced by human agency (deliberately or accidentally), as well as where it has been re-introduced following extirpation.
for species which are found in different regions at different times of year, terms such as summer range and winter range are often employed.
for species where only part of their range is used for breeding activity, the terms breeding range and non-breeding range are used.
when discussing mobile animals, the species' natural range is often discussed, as opposed to areas where it occurs as a vagrant
Vagrancy (biology)

Vagrancy is a phenomenon in biology whereby individual animals appear well outside their normal range ; individual animals which exhibit vagrancy are known as vagrants....
.
geographic or temporal qualifiers are often added e.g. British range or pre-1950 range.

There are at least five types of distribution patterns:

-scattered/random (Random placement)

-clustered/grouped (The majority are placed in one area)

-linear (Their placements form a line)

-radial (Placements form a ' x ' shape)

-Regular/ordered (They're not random at all, but follow a set placement. Much like a grid)

Colonisation (biology)

Colonisation is the process in biology by which a species spreads into new areas. The term can be used to describe colonisation on a small scale or on a large scale ....
Species distribution
Species distribution

Species distribution is the manner in which groups of species are spread out. There are three distinct types: clumped, uniform, and random. A similar concept is the species range, which focuses more on the factors determining a species' distribution....
Biological dispersal
Biological dispersal

Biological dispersal refers to a species movement away from an existing population or away from the parent organism. Through simply moving from one habitat patch to another, the dispersal of an individual has consequences not only for individual fitness, but also for population dynamics, population genetics, and species distribution....
