Population Distribution Maps
By Michael Grififn
What are Distribution Patterns?
They are ways to determine how organisms are interacting with each other in their area. There are 3 types of population distribution patterns: Random, Uniform, and Clumped (aggregated).
Random Distribution Pattern - Sanjiuang, China
This is an example of a random distribution pattern because the trees and plants are everywhere and they do need a specific resource. They are spaces at unpredictable distances from each other. As seen from wind-dispersed seeds. An example of a density independent factor would be a flood since there is a lake or pond nearby.
Uniform Distribution Pattern - Valencia, Spain
This is an example of an uniform distribution pattern because the trees are evenly spaced over the area they encompass. An independent limiting factor would be a lack of rain or severe heat because it would kill them all.
Clumped Distribution Pattern - Illinois
This is an example of a clumped distribution pattern because the dandelions are all grouped together. The dandelions are all clumped together because they like their home and the grass and the resources provided. A dependent limiting factor would be the temperature because if it gets too hot or cold, they will not survive.
