Range (biology)

In biology, the range or distribution of a species is the geographical area where that species live in.

The three basic types of population distribution within an area. From top to bottom: spaced (uniform/regular), random and clumped (aggregated).

Sometimes, when species are found in different regions at different times of year, terms such as summer range and winter range can be used. When discussing about animals, the species' natural range is often discussed.

There are at least five types of distribution patterns:

• 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 are not random at all, but follow a set placement.)
