What is uniform dispersion in biology?
Uniform dispersion. In uniform dispersion, individuals of a population are spaced more or less evenly. One example of uniform dispersion comes from plants that secrete toxins to inhibit growth of nearby individuals—a phenomenon called allelopathy. In a clumped dispersion, individuals are clustered in groups.
What is uniform distribution in ecology?
In uniform distribution, organisms are spread out in a fairly regular pattern. This occurs often where individuals must compete for a limiting resource, such as water or light. Desert shrubs and redwood trees grow in a uniform distribution—shrubs compete for water, while redwoods compete for light.
What animals have uniform dispersion?
Territorial birds, such as penguins, tend to have uniform distribution. Plants with wind-dispersed seeds, such as dandelions, are usually distributed randomly. Animals, such as elephants, that travel in groups exhibit clumped distribution.
Why is random distribution so rare?
Random distribution is rare in nature as biotic factors, such as the interactions with neighboring individuals, and abiotic factors, such as climate or soil conditions, generally cause organisms to be either clustered or spread. Random distributions exhibit chance clumps (see Poisson clumping).
What causes uniform dispersion?
Uniform patterns of dispersion are generally a result of interactions between individuals like competition and territoriality. Clumped patterns usually occur when resources are concentrated in small areas within a larger habitat or because of individuals forming social groups.
What causes random dispersion?
Individuals of a population can be spaced in different ways called dispersion patterns. In uniform dispersion, individuals are evenly spaced. In random dispersion, individuals are randomly arranged. This pattern can also be caused by the formation of social groups based on protection or hunting.
Which is an example of a uniform dispersion?
Uniform dispersion. In uniform dispersion, individuals of a population are spaced more or less evenly. One example of uniform dispersion comes from plants that secrete toxins to inhibit growth of nearby individuals—a phenomenon called allelopathy.
How are individuals spaced in a dispersion pattern?
Lesson Summary. Individuals of a population can be spaced in different ways called dispersion patterns. In uniform dispersion, individuals are evenly spaced. In random dispersion, individuals are randomly arranged.
Which is the best description of a clumped dispersion pattern?
Types of Dispersion Patterns. Clumped dispersion is when individuals in a population are clustered together, creating some patches with many individuals and some patches with no individuals. In uniform dispersion, individuals are spaced evenly throughout an area. And in random dispersion, individuals are arranged without any apparent pattern.
What is the shape of a discrete uniform distribution?
Discrete uniform distribution shows that variables in a range have the same probability of occurring. There are no variations in probable outcomes and the data is discrete, rather than continuous. Its shape resembles a rectangle, rather than the normal distribution’s bell.
